Making Your New Year’s Resolution Last: How an Air Purifier Can Optimize Your Workout

A popular goal among those who participate in setting New Year’s resolutions is the commitment to exercising more often and more consistently. However, the quality of the air we breathe during workouts is an often overlooked factor that can significantly impact our performance and overall health. Just as you wouldn’t use equipment or consume products that hinder your progress or pose harm, it’s essential to hold the air you breathe to the same high standard for optimized athletic performance.

Continue reading to learn from air quality specialists about how an air purifier can protect your health and enhance your workouts.

How Does Air Pollution Affect Athletic Performance? 

There is a long-standing scientific link between exposure to air pollution and declines in academic performance; these effects become even more prominent in more advanced athletes. Researchers have found that air pollution levels are predictors of athletic performance in populations ranging from average Americans to high school track runners and even Olympic athletes, with short-term air pollution exposure having greater impacts than long-term exposure. 

Extensively documented evidence underscores the notable impact of exercising amidst pollutants on respiratory health as a whole. When engaging in physical exertion, even activities such as yoga and weight-lifting that may not necessarily induce breathlessness, the heightened oxygen requirement of the muscles necessitates deeper and more frequent inhalations compared to a state of rest. As a result, the amplified intake of air during exercise exposes the lungs to an increased concentration of pollutants.

When exercising, the increased rate of breathing and airflow velocity make you more vulnerable to the effects of air pollution. Keep an eye out for the following impacts during your workout:

• Respiratory irritation, including coughing, sneezing, watering eyes, sore throat, and runny nose.
• Worsening of respiratory conditions such as asthma and COPD.
• Increased likelihood of developing bronchitis and other respiratory infections. 
• Dizziness, confusion, and decreased cognitive function.

For individuals at all levels of athletic ability, exercising in an environment that causes unnecessary physical discomfort and/or pain may become a deterrent from exercising altogether.

What Air Pollutants Are Found in Home Gyms and Fitness Centers?

While the health impacts of outdoor air pollution are a primary concern for many, it is worth noting that indoor air can be up to fifty times more polluted. Structures from previous eras were frequently constructed with stringent seals to prevent outdoor air pollution from infiltrating indoors. However, the unintended consequence of that construction technique is that it can also trap indoor pollutants and any outdoor contaminants that manage to enter through doors and windows. 

Pollutants commonly found inside gyms and home gyms include:

• Particulate matter (PM). Particulate matter is a common air pollutant which is defined as any solid or liquid substance suspended in the air. There are three subcategories of particulate matter, based on the size of the particles: PM10 (anything less than ten microns in diameter), PM2.5 (anything less than 2.5 microns in diameter), and PM1 (anything less than 1 micron in diameter). The smallest particles can penetrate the lungs’ alveoli and enter the bloodstream, causing harm to major organs including the brain. Particulate matter includes common everyday pollutants such as pet dander, dust, and pollen, but can also include more directly harmful substances such as byproducts of the combustion process. The infected respiratory droplets and aerosols that are responsible for spreading COVID-19 are also classified as particulate matter.
• Carbon monoxide (CO). Carbon monoxide is a silent and invisible gas that can lead to dizziness, confusion, or even fatality. Although natural sources like volcanoes or lightning exist, it is primarily produced through incomplete combustion in everyday items such as car engines, fireplaces, lanterns, stoves, and furnaces. If your home gym is located in your garage, it is crucial to be mindful of this potentially lethal pollutant.
• Volatile organic compounds (VOCs). Volatile organic compounds (VOCs) are gaseous or molecular pollutants that commonly originate from indoor sources, such as cleaning chemicals, air fresheners, and even off-gassing from low-priced, mass-produced furniture (including exercise equipment). VOCs are characterized by high vapor pressure and a low boiling point, resulting in a gaseous state at room temperature. Benzene, ethylene glycol, formaldehyde, methylene chloride, tetrachloroethylene, toluene, xylene, and 1,3-butadiene are among the commonly found VOCs.

Other common pollutants may include nitrogen oxides (NOx) and ozone (O3). 

Home Gym Air Pollution Sources

Sources of indoor air pollution in home gyms can also vary wildly, depending on the location of your home gym within your home, as well as the location of your home.

The air supply in your home gym is likely shared with the rest of your house. Consequently, the pollution generated by your day-to-day activities could potentially affect your workout sessions. The panel air filters typically utilized in HVAC systems are designed to safeguard the equipment from excessive debris. They do not offer an adequate level of filtration to safeguard human lungs against most particulate matter, nor do they provide any defense against gaseous pollutants, such as volatile organic compounds, which are a significant risk when exercising at home.

For home gyms located in garages, other uses of the space, such as tool and chemical usage, or parking a car, present additional risks of harmful air pollution.

Many people who exercise primarily at home do so in their living room, bedroom, home office, or other location used for multiple purposes. Even if you have a specifically designated space for a home gym in your house or apartment, managing indoor air pollution in the areas where you exercise is important. Indoor air pollution can have negative long- and short-term effects on your body even at rest, which are heightened during exercise when the lungs are working harder and taking in more air.

Additionally, the makeup of the air pollution inside your home is, in part, determined by where it is located. Homes located near major roadways or industrial areas will have lower indoor air quality than those with minimal nearby pollution sources unless adequate air filtration systems are put in place.

Why Your Home Gym Needs an Air Purifier in 2024

• Reach Your Athletic Goals. Breathing clean air has been shown to increase athletic performance. When you breathe in clean air, your body is more easily able to deliver oxygen to your muscles, increasing strength and endurance. Additionally, because air purifiers help eliminate harmful airborne particles, you’ll be less likely to experience headaches, dizziness, and other short-term side effects that are likely to hinder your performance.
• Eliminate Allergens. Indoor air in houses and apartments is often full of pollen, pet dander, dust, mold spores, and other allergens, even in the winter. The presence of allergens can make exercising uncomfortable and exacerbate seasonal allergies, asthma, and other respiratory conditions. Allergens are a type of particulate matter, meaning that they can be effectively targeted by a true HEPA filter.
• Reduce Health Risks. As discussed above, breathing polluted air during exercises strains the respiratory system and poses short- and long-term health risks.  Short-term symptoms include coughing, wheezing, headaches, and nausea. Long-term effects can be more serious and include respiratory diseases and heart complications. Air purifiers with activated carbon filters are particularly effective at removing harmful pollutants like ozone and volatile organic compounds (VOCs) to prevent health complications.
• Create a Comfortable Atmosphere to Stick to a Routine. Using air purifiers in your home gym to reduce indoor air pollution and increase the circulation of clean air helps to create a comfortable, rejuvenating atmosphere that will make working out a more positive experience. When working out is more physically comfortable, sticking to a routine and making exercise a habit becomes easier.

Finding the Right Air Purifier for Your Home Gym

The ideal air purifier for a home gym should be able to target both particulate matter and gaseous pollutants. For the most effective results, choose an air purifier that uses a factory-tested and certified HEPA filter (to target particulate pollution) and an activated carbon filter (to target gaseous pollutants).

To target gaseous pollutants, including volatile organic compounds, and particulate matter, use an air purifier that uses a scan-tested and certified HEPA air filter and an activated carbon filter, such as Camfil’s City M. The City M is a standalone in-room air purifier that you can plug into any standard outlet and use immediately with no special installation or HVAC specifications required.

Air Filter Procurement Guide: How to Properly Procure Air Filters

The importance of procuring high-quality air filters cannot be overstated. The proper air filters not only ensure the health and well-being of the occupants but also contribute significantly to the building’s energy efficiency and longevity.

Many professionals should be able to understand the technical, environmental, and economic aspects of air filtration equipment, as well as what an HVAC technician will see when installing and replacing filters, to make the best purchasing decisions for their organizations. Professionals involved in air filter purchasing decisions include procurement managers, procurement specialists, buyers, purchasing agents, purchasing managers, supply chain managers, chief financial officers, accounting managers, quality control personnel, quality engineers, and quality managers. Getting all of these professionals up to speed and on the same page about air filter procurement is a challenging task.

Camfil has launched a new series of videos where their Director of Comfort Air, r Dave Blackwell discusses the process of air filter procurement for commercial buildings and provides steps for ensuring that you are getting the highest quality filters for your building’s specific needs.

This article will serve as an additional resource for those who are responsible for ensuring the air quality in commercial buildings. In the following sections, we will navigate you through the process of identifying, selecting, and obtaining the highest-quality air filters for your commercial building.

Problem Identification: Why RFQ Doesn’t Work

In most cases, companies use an RFQ (request for quote) to procure air filters. The RFQ process typically involves requesting quotes from multiple suppliers and then comparing them based on price and delivery time.  For example, a large corporation purchasing paper goods for numerous facilities across North America may list a need for 5000 boxes of two-ply, soft, facial tissues in two different-sized containers. Suppliers responding to this RFQ would input their price per piece for each size on a spreadsheet included with the RFQ. The assumption is made that the products submitted by all suppliers responding to the RFQ are the same or at least similar enough from a performance perspective that users would be unable to tell the difference.

Unfortunately, many companies currently source air filters the same way. Often, the only  requirements listed are the size of the filter,  the efficiency (MERV rating) and sometimes  the annual quantity is included. The filters are listed on a spreadsheet and the supplier is requested to submit (quote) their best price for each filter size / MERV rating. The assumption is filters submitted by various suppliers are all basically the same, or  close in performance. Since the piece price of each filter is the primary factor for  the supplier  granted the business, a bidding war begins and the lowest bid wins. The company adds up the savings and assumes that by using this commodity-type purchasing procedure to source air filters, they’ve saved the company X% of money.

However, air filters are not commodity products, but highly technical pieces of equipment. While it may be true that there is no significant difference in performance between various types of 2-ply facial tissues, the same cannot be said for air filters of the same depth and MERV rating.  

An air filter is just one component (and often one of the lowest priced) in a much larger and more complex HVAC system. However, an air filter can have drastic effects on the overall performance (and therefore, the operational cost) of the entire HVAC system. Poor quality filters that become clogged quickly drive up energy prices and reduce air circulation. Air filters that allow debris to pass through can result in major damage to sensitive HVAC equipment that requires expensive repairs. Sourcing air filters as if they are commodities costs money. It does not save money.

 The Technical Nature of Air Filters

Air filters may seem like a simple and straightforward product, but they are actually quite technical in nature. There are various types of air filters available in the market, each with its own unique features and specifications. This makes it difficult for procurement teams to identify  and specify the optimum air filter for each HVAC system within  their building using a spreadsheet. Hidden Lifetime Costs of Air Filters

When procuring air filters, it’s crucial to consider more than just the initial purchase price. There are several hidden lifetime costs associated with air filters that are often overlooked, which can significantly impact a company’s budget and the health of building occupants.

• Energy Costs. Air filters directly affect the energy efficiency of your HVAC system. A poor-quality, old, or clogged filter can make the system work harder to maintain air quality and temperature, leading to increased energy consumption and higher utility bills. Look for filters with a 5-Star Energy Cost Index rating for the lowest energy consumption.
• Labor and Replacement Costs. Filter change frequency depends on the quality of the filter and the environmental conditions. Lower-quality filters require more frequent replacements, resulting in higher labor costs. When in-house maintenance staff is used, the lost labor hours could have been reallocated to far more valuable projects. Replacing an air filter also necessitates the disposal of the old filter, which is another expense that needs to be accounted for when assessing lifetime costs.
• Health Implications. The quality of air filters also has direct implications on occupant health. Lower-quality filters allow more pollutants and allergens to circulate in the indoor air, impacting not only the physical health of occupants and employees but also their cognitive functioning and capacity for productivity. Inadequate air filtration therefore leads to additional costs as a result of increased employee sick days and decreased productivity. (Read more: Exploring the Link Between Better Indoor Air Quality and Improved Productivity.)

It’s important to remember that financing for energy usage, contracted maintenance, and employee labor are likely handled by different departments in large organizations, and budgets may be fragmented even further in regional and national companies that operate dozens of buildings in multiple districts.

Because costs are possibly dispersed into different budgets, it can be difficult to see just how much current air filters are costing your company.

Learn more: How Do You Know If Your Air Filters Are Costing You Extra?

Why Cheap Air Filters Need to Be Replaced So Frequently

There are air filters that incorporate an electrostatic charge which essentially functions as a magnet for particulate matter, enhancing particle capture efficiency across all three size ranges. Consequently, manufacturers can assign the filter a higher MERV value after factory testing. However, as the filter accumulates dirt, the charge loses its ability to attract particles, causing a decline in the actual particle capture efficiency of the filter.

A MERV-13 filter, for example, can drop to a particle capture efficiency equivalent to that of a  MERV-8 filter within a short period of time, sometimes as little as a month, leaving people and equipment less protected than expected.  ASHRAE’s testing standards specify an optional testing method for determining filter efficiency without electrostatic charge. The values determined from this test are MERV-A values. MERV-A-rated filters will retain their rated efficiency across the lifespan of the filter.  An easy way to remember the distinction between MERV and MERV-A is to think of the “A” as standing for “actual,” so a filter’s MERV-A rating represents its “actual” efficiency. 

Additional Resources for Air Filter Procurement

For those seeking in-depth knowledge and understanding of air filter procurement, the following resources are useful:

• Camfil’s official website provides a range of expert advice, product details, case studies, industry news, and insightful articles.
• Camfil’s YouTube channel provides comprehensive and easily digestible information on a wide array of including cost-efficiency, maintenance, and quality assessment.

Camfil’s Solution for Air Filter Procurement:  Focusing on TCO

Understanding the application and performance expectations of each air filter is crucial in making the best-informed decision for your commercial building. Not all air filters are made equal, and it’s important to choose a high-quality air filter that meets or exceeds industry standards and fits the unique needs of each building, which include:

• HVAC System Specifications. Many commercial HVAC systems have shallow tracts to house filters, usually limiting options to one-,  two-  or four-inch deep air filters. (Learn more: Do All Air Handling Units Use the Same Air Filter?) 
• Air Pollution Composition.  The location of your building and local air quality, in addition to what indoor air pollutants are being generated inside the building, are important factors to consider when selecting an air filter.
• Air Quality Goals. Each organization’s goals for indoor air quality in their buildings may vary based on recommendations from professional organizations, state regulations, and federal standards.

Once the factors have been considered, the ideal filtration solution will consider the total cost of ownership (TCO) rather than the initial purchasing price of individual filters.

Air filters may seem like a small expense, but they can add up over time. Consider the total cost of ownership when selecting an air filter, including initial purchase price, replacement frequency, and energy efficiency. A lower-priced filter may seem like a bargain, but if it needs to be replaced more frequently or has higher energy consumption, it may end up costing your company more in the long run.

Example Analysis

The following example uses round numbers to illustrate the difference in TCO between an inexpensive commodity filter and a higher-priced technical filter. The figures do not represent real filter or energy prices. For a real-life example of the savings a building-wide filter upgrade can bring, read about how Nasville’s Music City Center decreased labor by 80% and energy consumption by 34% with Camfil air filters.

 

Cost Category	Inexpensive Commodity Filter	Premium Technical filter
Filter Replacements	4 x $10 = $40	1 x $20 = $20
Replacement Labor	4 x $10 = $40	1 x $10 = $10
Disposal	4 x $5 = $20	1 x $5 = $5
Annual Energy Usage	$10	$5
Total	$110	$40

In this example, purchasing the higher quality filter saves $70 annually for every filter opening in the HVAC system that requires a filter to be in place. Within just one commercial building, savings can quickly add up, and for large organizations with branches across the country and internationally, it can quickly total tens or even hundreds of thousands of dollars saved each year.

 The above example only considers costs that are easily quantifiable and generally consistent and predictable across time. Cheap panel filters, which lose their rated effectiveness rapidly (sometimes in as little as one month), additional costs such as maintenance and downtime for damaged HVAC equipment, and decreased employee productivity due to poor air quality must be added to the total cost of ownership. Additionally, when workers gain access to rooftops using ladders or lifts, it can affect employee productivity or the customer shopping experience in retail environments. This is especially bothersome if quarterly service is needed due to air filters with limited service life. Plus, repeated worker visits during very hot or very cold days can damage sensitive roof membranes requiring expensive repairs.  

To accurately calculate the total cost of ownership (TCO) and potential savings of air filter procurement for your specific organization, seeking expert guidance can prove invaluable. Industry specialists, well-versed in HVAC systems, can conduct a comprehensive analysis of your current air filter usage, energy consumption, and replacement frequency, providing a detailed cost-benefit analysis. This will not only assist you in identifying the most cost-effective and efficient air filters for your needs but also help identify which pollutants affect your building the most. Furthermore, having an expert on board ensures that all factors influencing the TCO are taken into account, enabling your organization to make an informed decision that optimizes both financial savings and air quality.

Recommended Action Plan

Evaluating the effectiveness of your current air filtration technology and determining what changes need to be made can be a lengthy and potentially complicated process.

Camfil recommends beginning the process three to four months in advance of your next scheduled filter changeout for larger organizations with multiple buildings. Smaller organizations need less time, but consulting with an air quality professional sooner rather than later is recommended for the best results.

Changing the Approach to Air Filter Procurement for Cost Savings and Better Results

Proper air filter procurement is crucial for the well-being of both the personnel and the HVAC equipment in a commercial building. It’s not simply about securing the most affordable filters, but rather sourcing filters that ensure optimal air quality and energy efficiency. The right filters can mitigate pollutant impact, reduce downtime and maintenance costs, and enhance overall productivity. Undertaking a comprehensive cost-benefit analysis with the aid of industry specialists can guide organizations in making a well-informed decision that optimizes financial savings and air quality. Starting this process well in advance of the next filter changeout is recommended to achieve the best results.

The Role of Air Filters in Air Handling Units for Maintaining Commercial and Public Building Indoor Air Quality

Ensuring high indoor air quality in commercial and public spaces is crucial for the well-being, health, and comfort of occupants and visitors. According to the Environmental Protection Agency, Americans typically spend around 90% of their time indoors, including prolonged periods at work. 

The EPA notes that indoor air can often contain more pollutants than outdoor air. Consequently, subpar indoor air quality can lead to significant health issues. The resulting loss in productivity and increased sick days can lead to national revenue losses amounting to tens of billions of dollars each year.

What causes poor indoor air quality?

Indoor air quality can be diminished by a range of pollutants and chemicals originating from both outside and inside the building. Building occupants may be exposed to these harmful elements for long and frequent durations. The EPA cites the following:  

• Biological contaminants like bacteria, viruses, pollen, mold, dust mites, and water spills can enter enclosed spaces, triggering allergic reactions, shortness of breath, dizziness, and infectious illnesses such as influenza. 
• Chemical pollutants from sources like tobacco smoke, cleaning products, gases expelled by building materials and furnishings can irritate the nose, throat, lungs, and cause headaches. 
• Suspended air particles and pathogens can remain suspended in the air or travel on air currents until they settle on surfaces or individuals. These contaminants are more likely to spread among people in indoor environments due to higher concentrations, raising the risk of diseases such as influenza. 

The Role of Air Handling Units in Building Environments

Today’s modern buildings feature complex designs with diverse spaces dedicated to different functions, making it challenging to ensure proper ventilation and air quality throughout. HVAC systems are the first line of defense in removing and diluting airborne pollutants. 

Central to the systems are air handling units (AHUs), which process and circulate clean air back into the building through a network of ducts. Commonly positioned on rooftops, AHUs draw in outdoor air, filtering contaminants before redistribution. They have a direct impact on indoor air quality and the HVAC system’s lifespan by keeping equipment clean.

Central to the systems are the air handling units (AHU) which contain equipment such as cooling coils or heating elements that condition the air for temperature and humidity. A certain percentage of outdoor air is mixed with the recirculated indoor air to maintain a regular supply of fresh air. Powerful fans then direct the air mixture through filters for contaminant removal and then throughout the building within a network of ducts. 

MERV (minimum efficiency reporting values) indicates a filter’s effectiveness at trapping particles between 0.3 to 10 microns in size. This rating, established by ASHRAE Standard 52.2, aids in  selecting the appropriate filter for specific filtration need. ISO has introduced a filter standard as well, known as  ISO16890. This standard relies on  particle sizes classified into  PM1, PM2.5, and PM10. The table below is helpful when determining the appropriate filter efficiency required and the relationship between MERV and ISO16890.

During the pandemic, ASHRAE’s Epidemic Task Force  recommended  using filters with a minimum  MERV 13 rating for HVAC systems and many still follow the recommendation today. Filter selection should also consider the specific HVAC system’s capabilities to properly hold the filter in place and move air through the filter.  While HEPA filters might seem like a universal solution due to their high filtration levels, HEPAs require specialized holding frames and fans that can overcome the higher resistance to airflow which  could render them an impractical choice.

Air Filter Types for AHUs in Commercial Settings

AHUs in commercial buildings are generally larger and more powerful which means they are often capable of holding a wide variety of air filter styles.  Here are various filters with the respective MERV ratings:

• HEPA or high-efficiency particulate air filters have very high efficiency, capturing a minimum of 99.97% of particles  as small as 0.3-microns which include respiratory aerosols that could contain harmful viruses.  The particles are much smaller than the eye can see.  
• V-bank style mini-pleats are the high-performance air filters on the market today for general ventilation. They have a very low resistance to airflow and coupled with the high dirt-holding capacity,  can remain in service for long periods. In some applications, V-bank-style filters can remain operating in AHUs for up to three years. 

• Bag filters are prevalent in commercial and public structure HVAC systems  for both primary and secondary filtering stages. Bag filters can be standalone for general air quality or act as pre-filters for specialized environments. The filters are also installed in the exhaust air or recirculation systems to protect air handling units.  With MERV ratings from 11 – 15, bag filters offer higher dust-holding capacity and longer lifetimes than most other filters. 

• Pleated panel filters are used as the primary filter in AHUs with limited space for air filters.  In AHUs with multiple filtration stages, panel filters are used as prefilters to keep the heating and cooling coils clean and to protect and extend the life of more expensive final filters by capturing larger particles in ventilation intake or recirculation air. The filters have a MERV rating of 8 to 13.

• Molecular filters are designed to eliminate gases, vapors, and molecular-scale pollutants. These substances are up to 1,000  times smaller than the particles that HEPA filters can capture. Molecular filters often use activated carbon or alumina to trap these tiny molecules using the adsorption filtration principle.

Air Filtration Solutions for Different Facilities

No single filter type is universally ideal for all commercial and public buildings. For instance, the filters needed in airports differ from those required in restaurants due to the various sizes and types of airborne particles that must be removed. The filter choice also hinges on several factors, including the capacity of the existing AHUs, the building’s function, cost considerations, desired efficiency levels, air quality objectives, and compatibility with the existing HVAC system. The overarching objective is to improve indoor air quality.

Below is a snapshot of the requirements and types of filters used in different spaces.

Airports 

Every day, millions of passengers pass through airport terminals, inadvertently shedding particles from their luggage, skin, and clothing that pollute the air. This is compounded by diesel fumes from passenger buses and baggage wagons, and the vapors from cleaning chemicals used within the terminal.

Airports combat these hazards by circulating a combination of outdoor and recirculated filtered indoor air,   throughout the terminals, thus protecting travelers and staff from dangerous substances. Typically, the central station HVAC systems or rooftop AHUs are equipped with air filters rated MERV 13 to 16, providing the greatest level of protection against fine particle contaminants while maintaining economic operation.

 Camfil, a leading manufacturer of premium clean air solutions, recommends these filters to strike an ideal balance between operational efficiency, long service life, and energy conservation. Additionally, carbon air filtration systems are employed to absorb diesel exhaust and odors from airport vehicles.

Retail Space

Maintaining fresh air in the confined spaces of shopping malls and retail stores is essential for a pleasant and safe shopping environment. Research indicates that indoor air quality in malls can be up to 10x times worse than air outdoors. A variety of factors contribute to this:  particles shed from customers’ skin and clothing, carbon dioxide from the breath of shoppers and staff, dust from restocking activities, intense cleaning processes, and emissions from transport vehicles all play a part in degrading air quality.

Short-term exposure to these elements can cause headaches and irritate the eyes and respiratory system. Airborne viruses shared by sick individuals can increase the risk of illness. Choosing an air filter depends on space, number of visitors, and type of airborne contaminants.  While there are no standards to follow, the Occupational Safety and Health Administration and ASHRAE recommends using filters with a minimum MERV rating of 13 to minimize the potential  spread of viruses such as COVID-19. 

 Hotels

Hotel guests expect easy check-ins, clean rooms, and fresh air.  In the hospitality industry, clean indoor air, along with climate control, ranks high on guests’ requests. Hotels face the challenge of filteringexternal pollution that seeps indoors, neutralizing cleaning agent odors, kitchen smoke, renovation dust, ductwork mold and bacteria, and carpet emissions. Different hotel zones like kitchens, lobbies, bars, and rooms each have unique air quality needs.

Energy-efficient filters with varying MERV ratings can effectively trap and remove a multitude of contaminants, from dust and bacteria to gases and volatile organic compounds (VOCs), to maintain high indoor air quality. These filters also contribute to energy savings and a lower carbon footprint.

Ensuring clean air is key to providing comfort and safeguarding the health of visitors, which in turn fosters guest loyalty and creates a wholesome environment for both work and leisure. While MERV 8-12 filters are commonly used for commercial buildings, higher MERV-rated filters such as 13-16,  control finer particles such as bacteria, tobacco smoke,  and some droplets from sneezes and coughs. The use of energy-efficient filters to improve indoor air quality can help save on energy costs that represent 15 – 20% of the total cost of hotel operations. 

Offices

Many offices have poor air circulation with outdated ventilation systems that just move unclean air from one part of the office to another. The wrong filters won’t offer the right results in removing small particles and odors in the air.  Studies indicate that good indoor air quality positively affects worker productivity.  

In addition to upgrading HVAC systems, office buildings should place the right filters throughout their space to purify air for occupants and increase the efficiency of HVAC systems. Filters with a MERV rating between 8 and 16 are recommended for the HVAC systems.  However, the higher the rating, the more contaminants a filter will block to protect equipment, operations, and building occupants.

Restaurants

Dining out is as much about the ambiance as it is about the food and service. Customers expect delicious meals, top-notch service, and a dining environment that’s comfortable and clean. Ensuring high-quality indoor air contributes to this experience by eliminating odors that can interfere with the enjoyment of the food and by safeguarding the health of both patrons and staff.

Managing the various spaces within a restaurant comes with distinct air quality challenges. Kitchens require robust ventilation to expel smoke, steam, and heat, while dining areas need to maintain an odor-free and comfortable environment. The solution is a proper combination of air filtration that removes oil and grease, collects particles, and eliminates gases responsible for odor.  

As outdoor air is brought in to replace the air extracted from kitchens and dining areas, it must be filtered to achieve high levels of indoor air quality. Fine airborne particles are particularly concerning and need to be efficiently captured with a minimum of  MERV 13 to 16 rated air filters,  ensuring an environment that meets the expectations for clean air in a dining setting.

Maintaining Filter Efficiency

After installing the appropriate air filters, it’s crucial to properly maintain them to ensure optimal performance and extend the life of the filters and the HVAC system. Buildings should have strict protocols for routine maintenance, checks, and filter replacements.  Ideally, air filters should be replaced when the resistance to airflow, aka pressure drop, increases to the point where clean airflow into the space is so restricted, proper conditions within the space are not being maintained.  Air filters should not be automatically replaced such as every one to three months. Changing air filters is an expensive undertaking and should be done when the filter’s usable service life is exhausted.  

Likewise, neglecting to replace filters when resistance has built up too high, can cause the filter to collapse in on itself and create serious bypass where no air is being filtered. Regularly monitoring pressure drop readings can be used to determine when filters need changing.  

Investing in high-quality air filtration to improve indoor air quality is directly associated with the good health, satisfaction, and productivity of building occupants and visitors and extended equipment life.

A specialist in air filtration, with expertise in servicing commercial and public buildings, can conduct a thorough evaluation and develop a tailored air filtration plan to meet the unique needs of the facility for the most effective results.

Commercial and Public Building Air Filters for Dental Offices: A Dental Health Imperative

Air quality in dental offices, like any healthcare facility, plays an important role in healing. Maintaining good indoor air quality is critical to good oral health, especially when patients have their mouths open for extended periods of time. 

When dentists and hygienists are caring for patients, whether through routine cleaning or more invasive dental procedures, the right air filters will reduce the presence of airborne contaminants, which not only benefits patients but also dentists and staff. Of course, dental practices also have to meet regulatory compliance standards to ensure a safe environment.

Let’s take a closer look at the importance of air quality in dental offices, the need for high-quality air filters, the challenges to maintaining clean air and the types of air filtration solutions and strategies available.

Air Quality in Dental Offices: Why It Matters

Maintaining good air quality in dental offices can reduce the risk of infection and illness caused by exposure to contaminants through the air and on dental instruments. Dentists, hygienists, and staff are also susceptible to health problems that can be traced back to airborne contaminants. 

Because dental procedures can produce airborne particles and hazardous aerosols that can be inhaled, proper air filtration and ventilation are needed to remove these substances from the air. Patients who suffer from respiratory conditions such as allergies and asthma can experience physical discomfort, breathing difficulty and fatigue when exposed to harmful substances in the air. 

Unpleasant odors from a variety of sources such as dental materials, biological substances and cleaning solutions can make people feel uneasy and nervous. Given the fear that many people associate with dental visits, effective air quality management can help put the patient at ease by reducing or eliminating odors.

Beyond the health of patients and dental staff, safety standards must be satisfied to meet regulatory requirements for infection control, transmission-based precautions and proper cleaning and disinfection. Air filtration, air filter efficiency, ventilation, air changes per hour,  staff training and air quality monitoring and recordkeeping are all key components of a comprehensive compliance strategy.

Potential Airborne Threats in a Dental Environment

A dental environment is susceptible to most of the same contaminants that can be found in any indoor environment, such as viruses, bacteria, allergens and dust particles. However, many substances are unique to dental environments and must be filtered continuously to maintain clean air and meet compliance requirements.

Saliva, blood and oral fluids can enter the air as aerosols and potentially spread airborne infections. This can occur during routine cleaning, scraping of plaque, drilling and other dental procedures. Endotoxins released by bacteria can increase the risk of fever, nausea, vomiting and other health issues.

Dental materials such as amalgam fillings can release mercury into the air, which can be harmful to the nervous system and kidneys. Some materials used to create an impression of the patient’s teeth can produce mercury vapor. Even asbestos, an ingredient found in older dental resins and impression material, can increase the risk of respiratory disease.

While disinfectants are necessary to clean various surfaces in dental offices and treatment rooms, the chemicals used to kill contaminants can be dangerous. Disinfectants can irritate the skin, eyes and respiratory tract and cause allergic reactions. Some disinfectants are toxic if inhaled or ingested. 

Air Filters:  Tailored for Dental Settings

Commercial HVAC systems continuously recirculate air inside the facility while adding a small volume of air from outside the facility. In addition to capturing particles brought in from the outside, air recirculated s within dental offices contains  contaminants   from dental procedures and patients and staff themselves that require filtering.. The air is drawn into the air filter by a fan and contaminants are captured as air passes through the filter and clean air is recirculated  into the room.

There are different types of filters that are commonly used in dental offices:

• HEPA filters. High-efficiency particulate air (HEPA) filters tested and certified to a minimum efficiency level of 99.97% on 0.3-micron-sized particles.
• MERV filters. Minimum Efficiency Reporting Value (MERV) filters are rated on a scale of 1 (largest particles) to 16 (smallest particles). 
• Activated carbon filters. Activated carbon filters utilize a technique known as adsorption to  remove gas, odors, volatile organic compounds (VOCs), and other molecular contaminants from the air.

These types of air filters are generally used to protect the air in  in dental treatment rooms but can also be used in other office areas, such as x-ray rooms and reception, to maximize effectiveness and prevent cross-contamination.

Challenges of Ensuring Optimal Air Quality in Dental Practices

As discussed previously, there are many types of contaminants in a dental environment. Viruses, bacteria, allergens, dust particles, aerosols formed from saliva, blood, and oral fluids from the patient, mercury vapor from dental materials, cleaning disinfectants, and various odors make proper air filtration in dental environments fairly complex.

Because aerosols and other types of airborne pollutants can be suspended in the air for a period of time, and patient turnover is fairly frequent in dental offices, there is an increased risk of these contaminants spreading. While dentists and staff can wear protective gear to reduce risk, patients are largely exposed.

Also, dental offices are typically small and part of a much larger facility, which can make it difficult to install the appropriate air filtration and ventilation systems. X-ray rooms, dental surgery suites and treatment rooms in particular require more advanced systems and air filters with higher ratings than the average office space. Designing a system to meet the specific demands of specialized spaces can be difficult.

Selecting the Right Air Filter for Dental Offices

There are many factors to consider when choosing air filters for dental offices. Start by answering the following questions.

• How big is your dental office? 
• How big are the rooms that have strict air filtration requirements?
• What types of procedures are performed?
• What types of contaminants need to be removed?
• What is your average daily patient volume?
• What is your patient turnover frequency?
• How is maintenance handled?
• What is your budget?

Air filters need to be paired with the HVAC equipment  to maximize efficiency and the right type to ensure effective removal of the most common contaminants in dental offices. The system will need to be configured to keep up with patient turnover. Of course, air filters need to be changed and systems maintained, so processes and filterlifespan need to be considered when choosing air filters specifically for a dental environment.

Emerging Innovations in Dental Air Filtration

Given heightened sensitivity to airborne contaminants and the spread of disease since the pandemic, dental practices and all healthcare facilities have been under pressure to implement more sophisticated air filtration and ventilation solutions. Innovation is a business imperative, and the industry is responding. 

Some HVAC systems use internet-connected sensors and artificial intelligence (AI) to monitor the air to ensure it  meets compliance standards. Modern systems can  provide real-time data on air quality, automatically adjust fan settings as needed and send alerts to technicians if air quality dips below a certain threshold and maintenance or repairs are needed. 

The capabilities can reduce exposure to harmful contaminants. The data generated by HVAC systems equipped with sensors  can  predict potential problems before they happen and optimize air quality.

Installation and Upkeep:  A Dental Perspective

Once the right air filters are chosen, they should be securely installed in an unobstructed location by a qualified technician. Properly installing  air filters in systems that supply air to  treatment rooms, waiting rooms, and reception is essential to maximizing effectiveness and efficiency. Follow the manufacturer’s instructions when installing as well as removing old filters for disposal. 

Like any equipment and technology, HVAC  systems and air filters should be maintained regularly. Gaskets should be inspected to ensure they are sealing and preventing bypass. Generally speaking, air filters should be replaced based on pressure drop and by the number of weeks or months they’ve been in service. The cost of energy to power the fan in an HVAC system is the single highest cost component of an air filtration program. Assuming the correct MERV value has been selected, air filters that maintain the lowest average resistance to pressure drop deliver the lowest total cost of ownership.. HVAC equipment  should be inspected according to the manufacturer’s recommendations. .

Conclusion:  Prioritizing Clean Air in Dental Care

Unlike most other types of healthcare practices, dental environments are home to procedures that have a direct, immediate impact on air quality. At the same time, dental practices face intense scrutiny to maintain a safe environment for staff and patients and meet compliance requirements that will likely increase in number and complexity.

With unique air quality challenges, a wide range of contaminants, and very strict compliance requirements, proper implementation and maintenance of highly effective air filtration and ventilation solutions are an absolute necessity. At the same time, continued research and innovation are needed to capture the smallest contaminants while maximizing efficiency and sustainability. 

Recognizing the important role air filters have in dental care, Camfil will continue to be a strong advocate for these efforts. Camfil partners with dental practices and property managers to design, install, and maintain air filtration and ventilation systems that meet the unique needs of the industry. Clean air in dental environments must remain a top priority, and Camfil will continue to step up with strategies and solutions that ensure safety and compliance.

The Importance of Air Filtration in Cities with Heavy Traffic

More than 45 million people in the United States live, work, or attend school within 300 feet of a major road, airport, or railroad. Air pollution in these areas can be especially high, meaning that people living close to large roads should be even more aware of the impacts of road traffic pollution.  

In this article, air pollution experts from Camfil explain the effects of air pollution resulting from excessive traffic in urban areas and the importance of air filtration to address these concerns. 

What Air Pollutants Come from Heavy Traffic?  

Cars, trucks, and other vehicles emit hundreds of different chemicals into the air, which are found in higher concentrations near major roads. Examples of common pollutants that are directly emitted by automobiles and other vehicles include: 

• Particulate matter (PM), also known as particle pollution, is a mixture of airborne particles made up of solid and liquid droplets. By themselves, these particles are so small,  they can be seen only with a microscope. In addition to road traffic, particulate matter comes from a variety of sources, such as power plants, construction activities, wood burning, and agricultural burning. Particulate matter can affect health in a number of ways. The smaller the particle, the deeper it can penetrate the lungs, leading to serious health risks such as heart and lung diseases. Long-term exposure to PM can cause asthma, bronchitis, and even premature death. PM can also have a detrimental effect on the environment, as it can cause smog and haze, reduce visibility, and damage crops.
• Carbon monoxide. Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that is released from combustion processes. It is a major component of vehicle exhaust, and can also come from gas or kerosene stoves, portable generators, and other combustion sources. Exposure to high levels of carbon monoxide can cause dizziness, headaches, weakness, confusion, and nausea, and can even be fatal in some cases. Long-term exposure can lead to brain damage, and pregnant women and fetuses are particularly sensitive to its effects. 
• Nitrogen oxides. Nitrogen oxides (NOx) are a group of air pollutants that are released into the atmosphere from combustion sources, such as vehicle exhaust, power plants, and industrial activities. These gases react with other pollutants to form dangerous particles, such as ozone, which can lead to respiratory problems and worsen asthma symptoms. NOx can also react with other chemicals in the atmosphere to form acid rain, which can damage crops, buildings, and aquatic life.
• Benzene. Benzene is a component of vehicle exhaust and is a known carcinogen, meaning it can cause cancer. People living near major roads, airports, or railroads are particularly at risk of inhaling benzene in their air. Research has shown that people who are exposed to higher levels of benzene in the air are more likely to have some types of cancers than those who are not exposed. 

Motor vehicles additionally release compounds that contribute to the generation of other pollutants in the atmosphere, including nitrogen dioxide, which is present in higher concentrations near main roads, and ozone, which forms further downwind. In addition to emissions from vehicle exhaust and evaporation, traffic on roadways also releases brake and tire particles and can disperse road dust into the air. Collectively and individually, numerous pollutants found in close proximity to roadways have been linked to negative health impacts.

How Does Pollution from Traffic Affect Human Health? 

People who live, work, or attend school near major roads have increased rates and increased severity of air pollution-related health problems, including: 

• Asthma onset and aggravation
• Cardiovascular disease
• Impaired lung development 
• Pre-term birth and low birth weight in infants
• Childhood leukemia 
• Premature deaths

Air pollution from traffic is associated with a wide range of adverse effects to human health. Long-term exposure to air pollutants from traffic can cause systemic damage to the body, including damage to the lungs, heart, and immune system. It can also aggravate existing medical conditions like asthma and allergies. Research has linked air pollution from traffic to increased risk of stroke, heart attack, lung cancer, and chronic obstructive pulmonary disease (COPD). Additionally, there is evidence that exposure to air pollution from traffic can cause cognitive impairments in children and adults, including reduced attention, memory, and executive functioning.

• Air Pollution and Migraines
• Air Pollution and Antibiotic Resistance

• Why Air Filters are Essential in Hospitals and Healthcare Facilities

What Factors Affect Air Pollution Levels Near Major Roads?

According to the EPA, there are many factors that influence the concentration and composition of air pollution in areas adjacent to major roadways:

• The type of vehicles and fuel being used. 
• Wind speed and direction. 
• Traffic conditions. 
• Climate and ground composition.

The highest concentrations of roadway pollutants occur on or just downwind of a roadway. With greater distance from a roadway, concentrations generally decrease to background levels within 500-600 feet. Pollutant concentrations tend to be higher when winds blow from the road and wind speeds are low.

The type of vehicles and fuel used, traffic activity, and the wind speed and direction can all have big effects on pollutant levels near major roadways. Generally, the more traffic, the higher the emissions; however, certain activities like congestion, stop-and-go movement or high-speed operations can increase emissions of certain pollutants. The combination of rush hour and calm winds in the morning often leads to the highest concentrations during this time of the day.

Emissions in close proximity to major roadways may be elevated due to a range of vehicle-related processes, including tailpipe exhaust, fuel evaporation, brake and tire wear, and traffic-induced dust. Concentrations of air pollution can rise under specific wind and terrain conditions, as well as during peak traffic hours. The dispersion of pollutants is influenced by structures such as sound walls, buildings, and vegetation. Generally, pollutant levels tend to decrease as one moves away from traffic, although the extent of this decrease may vary.

Traffic activity, wind speed, and direction can significantly impact pollutant concentrations. Typically, increased traffic results in higher emissions. However, specific factors such as congestion, stop-and-go movement, or high-speed operations can further contribute to the release of certain pollutants. The combination of rush hour and calm winds in the morning often leads to peak concentrations during this time of day. Other factors that influence pollutant concentrations include the composition of vehicles, roadway design, and neighboring land uses.

What About Air Pollution Inside Vehicles? 

The quality of air inside a vehicle is affected by nearby vehicles and occasionally by emissions from the vehicle itself. Research typically indicates elevated levels of air pollutants inside vehicles when trailing heavy-duty trucks and cars emitting visible tailpipe emissions. Following closely and stopping too near the vehicle ahead, whether in a traffic jam or at an intersection, can escalate air pollution in the subsequent vehicle. An important determinant of driver and passenger exposure is the ventilation system of the vehicle. Additionally, older diesel-powered buses may exhibit heightened concentrations of exhaust components within the cabin.

The air quality inside vehicles can be adversely affected by traffic emissions on the roadway, resulting in elevated concentrations of pollutants that mirror those present outside the vehicle. Studies consistently indicate higher concentrations of air pollutants in vehicles that are trailing heavy-duty trucks or cars emitting visible tailpipe emissions. Additionally, tailgating and closely following the vehicle ahead during traffic congestion can intensify air pollution in the following vehicle.

The ventilation of a vehicle plays a crucial role in determining the exposure of both drivers and passengers. When windows are open, fresh outdoor air enters the passenger compartment quickly. However, when windows are closed, the vehicle’s ventilation settings have a greater impact on exposure. If the ventilation system is set to bring in outside air, it enters rapidly. On the other hand, the recirculation setting reduces the amount of outdoor air entering the vehicle. In vehicles with properly functioning cabin air filters, recirculation helps reduce particulate matter (PM) concentrations from the outside. 

Older diesel buses, including school and public transit buses, may have higher levels of exhaust components inside the cabin. Emissions from the tailpipe and crankcase ventilation can lead to increased concentrations of PM and other air pollutants inside the cabin compared to outside. 

What Are the Worst Areas for Traffic-Related Pollution? 

Traffic-related air pollution is a major issue in many cities and communities across the globe. With large highways, infrastructure built around cars, and a culture of commuting, the United States is no exception, particularly in large metropolitan areas. 

The ten U.S. cities with the worst traffic, based on 2022 data, are: 

1. Chicago 
2. Boston
3. New York City
4. Philadelphia
5. Miami
6. Los Angeles
7. San Francisco
8. Washington, D.C.
9. Houston
10. Atlanta

These cities are all densely populated, with large numbers of people living, working, attending school, or all three, within three hundred feet of heavy traffic, putting them at risk of severe health issues due to pollutant exposure. 

Air Purifiers Protect  Building Occupants from Traffic-Related Air Pollution 

Air purifiers are an important tool for protecting building occupants, tenants, and guests from traffic-related air pollution in buildings located close to busy roads. 

Although controlling outdoor air pollution exposure can be challenging, the average American spends over 90% of their time indoors. Surprisingly, indoor air can be up to fifty times more polluted than outdoor air. Therefore, utilizing appropriate air filtration technology is crucial for enhancing indoor air quality and minimizing exposure to harmful air pollutants that can lead to both short- and long-term health consequences.

To ensure optimal protection against harmful pollutants, it is advisable to include a portable room air purifier equipped with both factory-tested and certified HEPA filters, designed to trap particulate matter, as well as activated carbon filters, which effectively eliminate gaseous pollutants like ozone, sulfur dioxide, nitrogen dioxide, and volatile organic compounds. With air purifiers in place, buildings are better protected against the negative impacts of traffic-related air pollution.
