How Air Pollutants Absorbed by Industrial Air Filters Are Threatening Plants and Animals (Update)

The air pollutants that industrial air filters remove from the air can harm the health of animals and plants as well as the health of humans.

When most people think about damage from air pollution, they think of it in terms of its effects on human health. This is understandable, as we’re humans and we filter what we know about the world through our own experiences. Yet it’s important to remember that air pollution negatively affects the entire world around us, which includes plant life and animal life as well.

Animals and plants are damaged by many of the same pollutants that damage human health, and since our ecosystem includes the plants and animals around us, it’s important to look at pollution reduction across the spectrum. After all, reducing the amount of air pollution in the environment doesn’t just benefit us by shielding our lungs from air pollution, it also benefits the animals and plants in our environment, which play a vital role in how we live our daily lives.

Commercial HVAC Air Filters Absorb Toxic Pollutants That Can Harm the Environment

Air pollutants can damage the leaves and roots of plants, and harm animal lungs in much the same manner that they harm human lungs. These pollutants come from a variety of sources: some are natural and some are man-made. It’s important to note, however, that man-made sources are the primary way most air pollutants get into the air.

The air pollutants released by human activity include:

  • Chlorofluorocarbons that are released by refrigerants, solvents, and propellants. They wear away at the stratospheric ozone layer, which protects the surface of the Earth from the sun’s ultraviolet radiation.
  • Nitrogen oxides and sulfur dioxide that come primarily from the combustion of fossil fuels at industrial facilities, power plants, and by motor vehicles. The pollutants contribute to the acidification of water droplets in the air, which causes acid rain.
  • Volatile organic compounds have a variety of human sources, and they are capable of interacting with heat and the chemical energy from the sun to create ground-level ozone.
  • Particulate matter is an umbrella term for any small particles of air pollution capable of doing damage to people’s health. Particulate matter is divided into different categories like PM1, PM2.5, and PM10 (these particles are smaller than 1-micron in size, smaller than 2.5-microns in size, and smaller than 10-microns in size respectively).

Commercial HVAC air filters are capable of removing most of these pollutants, but animals living outdoors can’t take advantage of their protective capabilities.

Commercial Air Filtration Systems Prevent The Damaging Health Effects Of Air Pollution

The various air pollutants released by human activity can harm plants and animals in a number of different ways. Acid rain and ozone can harm plants, while particulate matter can damage the lungs of animals. A weaker ozone layer can harm almost all life on the planet.

“The degradation of the ozone layer caused by chlorofluorocarbons means that more ultraviolet radiation hits the surface of the planet, damaging the leaves of plants and harming the skin of animals,” stated Camfil’s Mark Davidson, Manager of Marketing & Technical Materials and ASHRAE member and active committee participant. (1)

Unlike when ozone is in the upper atmosphere, tropospheric ozone is a harmful air pollutant that damages the lung tissue of animals and prevents plants from being able to respire. Since plants can’t respire when in clouds of ozone they can’t photosynthesize as efficiently, meaning they’re unable to grow.

In terms of how air pollution harms the lungs of animals, the lungs of other mammals tend to be similar in construction to the lungs of humans. Particulate matter and ozone air pollution can degrade the cells of the lungs, impacting their ability to supply the body with the oxygen it needs. Ozone and particulate matter can permanently decrease lung function if exposure to the air pollutants is at a high level or exposure continues over a long period of time. The two pollutants can lead to the development or exacerbation of asthma in humans, and to similar respiratory diseases in other animals.

Particulate matter can penetrate into the lungs and bloodstream of humans and other animals, doing substantial damage to the lungs and heart. In humans, exposure to particulate matter can cause stroke, brain damage, ischemic heart disease, and other cardiovascular or respiratory ailments. Particulate matter can also damage the body of animals in other ways.

“There is some evidence that other animals can develop similar ailments to humans,” explains Davidson. “Studies examining dogs from the heavily polluted regions of Mexico City found that the animals displayed forms of neurodegeneration similar to Alzheimer’s disease, not unlike the  implications for humans who are continually exposed to air pollution as well.” (2)

The Pollutants Neutralized by Industrial Air Filtration and Ventilation Can Harm Entire Ecosystems

Air pollutants can harm animals and plants in ways other than direct exposure. This is because air pollution can damage ecosystems and lead to global warming.

Acid rain is one-way air pollution can damage an entire ecosystem. It can easily destroy plant leaves, rendering the plants incapable of photosynthesis, which eventually causes them to die off. When the acidic water soaks into the ground it can also damage plant roots, and harm aquatic wildlife living in streams, ponds, and lakes.

Even if the damage caused by air pollution seems small, the die-off of a single species of fish in one pond, for example, can have ripple effects that harm many more animals and plants. Ecosystems depend on a delicate balance of interactions between different species. If one species dies off, it can destabilize an entire food web, leading to an ecosystem collapse.

“Species that play critical roles within an ecosystem are referred to as keystone species because the loss of them makes the entire arch (ecosystem) collapse,” expanded Davidson. “If a keystone species were to be damaged or wiped out by severe air pollution, the rest of the ecosystem would suffer greatly. If an insect cannot breed due to the acidification of the water it normally breeds in, the frogs that feed on it will have less food and can die off themselves.” (3)

Certain kinds of air pollution, like methane and carbon dioxide, also lead to global climate change. Global climate change can cause certain areas of the globe to warm and other areas to cool. The hotter climate is causing desertification of fragile ecosystems, the gradual elimination of vegetation and other forms of life from an area. Global climate change is also causing sea level rise due to the melting of the polar ice caps, causing many biomes and ecosystems near the shore to be flooded and swept out to sea.

Commercial HEPA Air Purifiers Are a Way to Protect Ourselves and Our Domestic Animals

The variety of air pollutants that can harm human and animal health can typically be captured with commercial HEPA air purifiers. HEPA stands for High-Efficiency Particulate Air, and it refers to the fact that the filters used in the purifier can absorb most of the dangerous air pollutants exposed in a home. While wild animals can’t benefit from these devices, domestic house pets and humans can, so it remains vital to use them to defend against damaging air pollutants.

When making purchasing decisions about commercial HEPA air purifiers, look for air purifiers that use replaceable HEPA filters. HEPA filters are capable of absorbing up to 99.97% of all particles of pollution as small as 0.3-microns in size. If you live in a particularly polluted area, you may wish to employ a HEPA air purifier to protect the health of your pet, as well as your own health.

Ecosystems Require Protection Beyond Air Filtration Units

It’s critical to think beyond air filtration units and to develop and sustain pollution control methods that will reduce overall emissions of air pollutants. Pollution control strategies can include regulations by government bodies, investments in clean energy and travel technology, and education about ways to reduce individual emissions of pollutants.

Government bodies have the power to create regulations that will curb emissions. It’s important to place limits on smokestack emissions from industrial facilities, mandate motor vehicle mileage standards, and institute cap and trade programs to incentivize companies to reduce air pollution emissions.

Investing in technology that reduces emissions is another way to improve air quality. Emissions reduction technology includes electrostatic precipitators, smokestack scrubbers, and catalytic converters. Electric vehicles and associated infrastructure like charging stations can also reduce emissions.

“Educational programs can help citizens understand the role they can play in curbing emissions and managing their carbon footprint,” claimed Davidson. “Educational programs can address how citizens can carpool, use public transportation, use energy efficient appliances, make use of environmentally-friendly cleaners, and lower their energy consumption to prevent air pollution.” (4)

Air pollution leads to shorter, unhappier, tougher lives for both animals and humans alike. It’s important to reduce our air pollution emissions where possible and to use commercial or industrial air filters to protect the health of our families and our pets.

The Growing Need for Better Air Filtration in Data Centers Amid the AI Boom

As the world accelerates into the age of artificial intelligence (AI), data centers—the heart of our digital economy—are facing new and unprecedented challenges. From powering complex algorithms to storing vast amounts of data, these hubs are critical for AI’s growth. However, with increased computing and energy demands, there is a pressing need to reevaluate how data centers manage their indoor environments, particularly in terms of air filtration. 

The AI Explosion and Its Strain on Data Centers

AI technologies are changing the nature of many industries, from healthcare and finance to manufacturing and entertainment. However, these advancements come at a significant cost in terms of computing power. As these systems evolve, the demand for processing power and storage continues to skyrocket.

AI is inherently energy-hungry. From training complex neural networks to running real-time inference on vast datasets, AI workloads are intensive. As AI systems scale, they require more servers, more storage, and more energy. AI models, especially large language models (LLMs) like GPT, require enormous computational resources. Training a single LLM comparable to GPT-3, for example, consumes approximately 10 gigawatt-hours (GWh), which is around the equivalent annual electricity consumption of over 1,000 American households. 

Data centers are already responsible for a significant portion of global energy consumption. The International Energy Agency (IEA) reported that data centers consumed about 1% of the world’s total electricity in 2020. With the surge in AI applications, that figure is expected to rise.  In fact, researchers from MIT’s Sloan School of Management estimate that by 2030, data centers could account for up to 21% of global energy demand with the current rate of growth of AI.

This explosion in demand has created a new level of strain on data centers. The more AI models are used, the more energy is consumed, and the more heat is generated. The physical infrastructure within these data centers is under immense pressure to keep up with this rapid growth, and one often overlooked aspect of their operations is air filtration. Better air filtration would not only improve the lifespan and efficiency of equipment but also reduce the need for overreliance on cooling systems, helping to minimize energy consumption and overall environmental impact.

The Impact of Poor Indoor Air Quality (IAQ) on Data Center Equipment

Data centers house highly sensitive servers and computing hardware that require pristine operating conditions. With thousands of servers running around the clock, cooling them becomes one of the most important challenges. The increased computing capacity needed for AI processing is producing higher heat loads, requiring data centers to ramp up cooling systems to maintain safe operating temperatures, but cooling systems alone are not enough. Air quality—the cleanliness of the air circulating in the data center—is a critical, yet often underestimated, element in ensuring that this massive energy consumption is sustainable in the long run.

Airborne contaminants such as dust, particulate matter, and chemical pollutants can infiltrate cooling systems and damage critical components. Accumulation of contaminants can lead to:

  • Overheating: Dust and particulates clog ventilation pathways, reducing airflow efficiency and increasing the risk of overheating, which can shorten hardware lifespan. Keeping data centers cool is essential to maintaining the performance and longevity of computing hardware. When servers overheat, they can throttle performance to prevent damage, leading to slower processing speeds and inefficiencies. In extreme cases, overheating can cause unexpected shutdowns, data loss, and irreversible damage to critical components.
  • Corrosion: Airborne pollutants such as sulfur compounds and moisture can corrode metal components, leading to system failures and costly downtime. This can be especially problematic for data centers located in high-humidity environments or areas with poor air quality.
  • Increased Maintenance Costs: Contaminated equipment requires more frequent cleaning and component replacement, driving up operational expenses. This can also result in additional labor costs as technicians must spend more time maintaining and repairing equipment.
  • Environmental Impact: The energy consumption of data centers is a major contributor to greenhouse gas emissions. Excessive heat can require additional cooling, leading to higher energy usage and a larger carbon footprint. In some jurisdictions, companies may be fined or otherwise penalized for unsustainable energy practices. 

WATCH: Corrosion in Data Centers

In addition to these technical concerns, poor air quality in data centers can reduce the overall lifespan of servers and other critical infrastructure. Server downtime due to overheating or malfunctioning equipment can lead to costly outages and data loss, which is a risk data centers and AI services simply cannot afford.

Prioritizing Data Center IAQ for Better Cybersecurity

Indoor air quality (IAQ) is not only crucial for hardware performance but also plays a role in cybersecurity. Contaminants such as dust and pollutants can lead to unexpected hardware malfunctions, increasing the risk of downtime and potential security vulnerabilities. A compromised cooling system due to poor air quality can force servers into emergency shutdowns, disrupting critical cybersecurity monitoring and exposing networks to external threats. In fact, cybersecurity experts from VentureBeat warn data center managers and tech users that modern-day attackers “aim to weaponize heat and exfiltrate billions of dollars in data from data centers by attacking cooling systems.”

By investing in high-efficiency air filtration, data centers can maintain a stable operating environment, ensuring that security systems, firewalls, and intrusion detection mechanisms remain continuously operational. Clean air helps safeguard both the physical and digital assets of an organization, reinforcing the resilience of data centers in an era of increasing cyber threats.

How Poor Filtration Increases Energy Costs

Selecting low-quality air filters may seem like a cost-saving measure, but it can lead to increased energy consumption and inefficiencies. Many budget-friendly filters have a high pressure drop, meaning they create resistance in airflow, forcing cooling systems to work harder to maintain optimal temperatures. This results in:

  • Higher Energy Usage: The additional strain on cooling fans and HVAC systems leads to greater electricity consumption, increasing overall operational costs.
  • Reduced Cooling Efficiency: Inadequate filtration allows more contaminants to pass through, causing HVAC components to clog faster and reducing cooling effectiveness.
  • Frequent Filter Replacements: Lower-grade air filters may require more frequent changes, adding to labor and material costs over time.

Resurgence of Nuclear Energy in the U.S. and the Integral Safety Role of Air Filtration

Learn how advanced air filtration systems are ensuring safety and compliance as nuclear energy makes a comeback in America’s energy industry. 

Nuclear energy is reclaiming its place as a reliable, carbon-free power source that strengthens both energy security and sustainability. In 2024, the U.S. government set targets to triple nuclear energy capacity by 2050. In 2023 alone, the U.S. Department of Energy reported a 20% increase in planned nuclear reactor projects, signaling a dramatic shift in the nation’s energy strategy. This resurgence isn’t just driven by government initiatives—tech giants like Amazon, Google and Meta are heavily investing in nuclear power to meet their ambitious clean energy goals.    

But with this nuclear revival comes an unwavering focus on safety. Modern reactor designs promise efficiency and resilience, yet robust safety measures remain paramount to prevent contamination and protect both workers and communities. Among these critical safeguards, air filtration stands as a cornerstone in nuclear facility safety, ensuring that hazardous particles and radioactive contaminants are effectively contained.

This blog examines the drivers behind nuclear energy’s resurgence, the essential role of high-efficiency air filtration in reactor safety and how innovations in filtration technology are shaping the future of nuclear power. As the U.S. embraces nuclear once again, understanding the intersection of clean energy growth and advanced safety systems is more important than ever.

The Nuclear Renaissance

From 1895 to 1945, significant advancements were made in the science of atomic radiation, atomic transformation and nuclear fission. Between 1939 and 1945, research efforts were primarily directed toward developing the atomic bomb. After 1945, the focus shifted to harnessing nuclear energy for controlled applications, including naval propulsion and electricity generation. Since 1956, the primary objective has been the continued technological advancement of reliable nuclear power plants.

Commercial nuclear power generation in the United States began in 1958. As of August 1, 2023, the country had 93 operational commercial nuclear reactors across 54 power plants in 28 states. A power plant refers to the entire facility, which may house both nuclear and non-nuclear electricity-generating units. Each nuclear reactor within a commercial plant is distinct, with its own personnel and equipment. The reactor generates heat to produce steam, which powers a turbine connected to a generator that produces electricity. Once a reactor is retired from commercial service, it undergoes a decommissioning process. As noted above, The U.S. Department of Energy has set ambitious targets to triple nuclear energy capacity by 2050, aiming to meet future power demands and achieve net-zero emissions. ​ 

Camfil’s Origins in Nuclear Air Filtration

In the early 1960s, Sweden embarked on its nuclear power program, necessitating high-quality air filters for its nuclear facilities. Recognizing the lack of suitable filters in Europe, Gösta Larson, working for a small air handling unit company, collaborated with Cambridge Filter Corporation in the U.S. to meet these stringent requirements. This partnership led to the founding of Camfil AB in 1963, establishing a legacy in providing clean air solutions for the nuclear industry. 

Role of Major Tech Companies in Supporting Nuclear Growth

Major technology companies are playing a pivotal role in the nuclear energy renaissance. Amazon, Google and Meta have signed a pledge to support the goal of tripling global nuclear capacity by 2050. These companies, known for their energy-intensive data centers, recognize nuclear power’s potential to provide consistent, carbon-free electricity to meet their sustainability objectives. 

Nuclear Power and Carbon Neutrality

The International Atomic Energy Agency (IAEA) emphasizes nuclear energy’s role in displacing coal and other fossil fuels, facilitating the integration of renewable energy sources and serving as an economic option for large-scale hydrogen production. These attributes underscore nuclear power’s versatility in supporting various aspects of a carbon-neutral energy infrastructure.

Nuclear power plants generate electricity without emitting greenhouse gases during operation. Over their entire lifecycle, nuclear energy produces a similar level of carbon dioxide-equivalent emissions per unit of electricity as wind power and only one-third of the emissions compared to solar energy, according to the World Nuclear Association.

Safety Challenges in Modern Nuclear Facilities

Ensuring safety in modern nuclear facilities is paramount, particularly concerning airborne hazards that can pose significant risks to both personnel and the environment.​ Historical nuclear incidents have prompted significant advancements in safety standards. For instance, the Three Mile Island and Fukushima accidents underscored the need for robust containment and filtration systems, leading to stricter regulations and improved safety protocols worldwide.​

Regulatory bodies, such as the U.S. Nuclear Regulatory Commission (NRC), mandate comprehensive criteria for the design, inspection, and testing of air filtration and adsorption units in nuclear facilities. These regulations ensure that engineered safety features effectively manage and mitigate airborne radioactive contaminants. 

Potential Airborne Hazards in Nuclear Environments

Airborne contamination in nuclear power plants primarily includes particulates, noble gases, radioiodine and tritium, which need to be carefully managed to keep workers and the environment safe. These contaminants can originate from routine operations, maintenance activities or accidental releases, necessitating stringent monitoring and control measures. Here are the main types: 

  • Particulates – These are microscopic particles of radioactive material that can become suspended in the air. If inhaled, they can get into the lungs and cause health issues, and they can settle on surfaces, leading to internal or external contamination.​
  • Noble Gases – Gases like krypton and xenon are produced during nuclear reactions. They are inert radioactive gases that, while not chemically reactive, can pose inhalation risks and contribute to external radiation exposure.
  • Radioactive Iodine – A specific type of radiation that can be absorbed by the thyroid gland, increasing the risk of thyroid cancer if not properly contained.
  • Tritium (Radioactive Hydrogen) – This type of radiation can mix with water, making it easy to spread in the environment. 

Consequences of Inadequate Air Filtration

Failure to implement effective air filtration systems can lead to the uncontrolled release of radioactive materials, resulting in environmental contamination and health hazards for workers and the public. Such incidents can erode public trust and lead to costly decontamination efforts and operational shutdowns.​

Current Best Practices for Containment and Air Filtration

Nuclear plant air filtration systems are used for containment control during dismantling or maintenance work at the site. Air cleaning and containment systems are vital in minimizing public exposure to radioactive material and protecting public safety.

Modern best practices include the use of high-efficiency particulate air (HEPA) filters, regular testing and maintenance of filtration systems and continuous airborne contamination monitoring. These measures are designed to ensure that any release of radioactive materials remains within permissible limits, safeguarding both personnel and the environment. ​

The Role of Different Facility Stakeholders in Maintaining Safety

Maintaining air safety in nuclear facilities is a collaborative effort involving various stakeholders:​

  • Facility Operators:  Responsible for implementing and adhering to safety protocols, conducting regular system checks and ensuring compliance with regulatory standards.​
  • Regulatory Bodies:  Establish and enforce safety regulations, conduct inspections and provide guidance on best practices.​
  • Maintenance Personnel:  Perform routine inspections, testing and maintenance of air filtration systems to ensure optimal functionality.​
  • Safety Engineers:  Design and evaluate air filtration and containment systems, ensuring they meet safety requirements and effectively mitigate risks.​

By addressing these safety challenges through stringent regulations, advanced technologies and collaborative efforts, modern nuclear facilities can effectively manage airborne hazards, ensuring the safety of both personnel and the surrounding environment.

Air Filtration Technology:  The First Line of Defense

Air filtration systems are crucial in nuclear facilities, serving as the primary barrier against the release of radioactive particles and gases into the environment. These systems ensure the safety of personnel, the public and the environment by effectively capturing and containing hazardous substances.​

Fundamental Principles of Nuclear Air Filtration

Nuclear air filtration operates on the principle of removing airborne radioactive contaminants through mechanical and adsorptive methods. Mechanical filtration captures particulate matter, while adsorptive techniques target gaseous contaminants. The design and operation of these systems are governed by stringent standards to ensure maximum efficiency and safety. 

HEPA Filtration Requirements Specific to Nuclear Applications

High-efficiency particulate air (HEPA) filters are the cornerstone of particulate removal in nuclear facilities. They are designed to capture at least 99.97% of particles as small as 0.3 microns. In nuclear settings, HEPA filters must meet rigorous standards, such as those outlined by the American Society of Mechanical Engineers (ASME) in the AG-1 Code on Nuclear Air and Gas Treatment. These specialized filters are designed, engineered and manufactured and tested to be suitable for use in high-risk nuclear facilities. In addition, the HEPA filters meet the UL-586 Standard for High Efficiency Particulate Air Filter Units, which ensures that they will not support a flame.

Carbon Adsorption for Gaseous Contaminants

Activated carbon filters are employed to adsorb radioactive gases, notably iodine isotopes, which pose significant health risks if released. High-efficiency gas adsorber (HEGA) filter, also known as a carbon adsorber. These filters are designed to adsorb potentially life-threatening contaminants in the air stream and are used in containment filtration systems. For an adsorber to qualify as a HEGA, it must demonstrate a minimum mechanical efficiency of 99.9% when tested according to the Institute of Environmental Sciences standard IEST-RP-CC008.2, which outlines the design and testing of modular gas-phase adsorbers. Additionally, the adsorber cell must be designed, constructed, filled and packaged in alignment with the core requirements of this standard.​

Camfil’s CamContain Self-Contained Systems:  Engineering for Nuclear Safety

Camfil’s CamContain systems are engineered to provide robust air filtration solutions, particularly in environments where hazardous contaminants pose significant risks. These self-contained units are designed to effectively remove radioactive, toxic or biological particles and gases, ensuring the safety of personnel and the environment.

​CamContain Technology

The CamContain series encompasses gastight welded filter housings tailored for critical applications. Constructed from stainless steel, these housings are gas-tight welded and torsion-resistant, meeting the highest safety demands required in sensitive environments. ​

Clean Air for Academic Success: Camfil’s Guide to Boosting School Performance by Improving IAQ

Indoor air quality in schools is often overlooked, yet it plays a critical role in student health, cognitive performance, and overall well-being. By addressing air quality proactively, schools can create safer and healthier spaces that enhance learning outcomes.

This article explores why clean air is vital for academic success, the air quality challenges schools face, and how filtration systems can mitigate these issues. Additionally, Camfil’s team of air quality specialists provides practical insights into choosing the right air filtration systems and strategies for schools to maximize their indoor air quality.

Air Quality Challenges in Schools

Schools are unique environments in terms of air quality, but share many of the same challenges as other commercial and public buildings.

Common Pollutants Found in Schools

Schools can harbor a variety of airborne pollutants, such as:

  • Particulate Matter (PM): Dust, dirt, and small particles that come from both indoor and outdoor sources.
  • Airborne Allergens:  Pollen, pet dander, and dust mites can trigger allergies and asthma symptoms in students and staff.
  • Biological Contaminants: Biological contaminants are microorganisms like bacteria and viruses that can pose the risk of illness outbreak when present in the air.
  • Mold: Often allowed to grow by poor ventilation or water damage, breathing in mold can cause a range of health issues, ranging from mild respiratory irritation to neurological and organ damage depending on the species of mold.
  • Volatile Organic Compounds (VOCs): Chemicals found in cleaning supplies, art materials, and building materials that can cause headaches, nausea, and other health issues.

Health Risks of Poor Air Quality

Exposure to these pollutants has significant health implications, particularly for elementary and middle school children, due to their lung capacity being larger relative to their body size than that of adults and because their respiratory systems are still developing. Poor air quality has been linked to:

  • Increased incidences of asthma and allergies
  • Cognitive impairments such as difficulty concentrating
  • Long-term risks like respiratory illnesses

In regard to the health effects of specific types of pollution, PM can irritate the respiratory system and exacerbate existing conditions like asthma. Allergens can trigger allergic reactions or even cause new allergies to develop over time with frequent exposure. Volatile Organic Compounds (VOCs) can pose serious health risks, including respiratory irritation, headaches, and long-term exposure may lead to liver, kidney, or central nervous system damage.

Added Challenges in Colleges and Universities

Although there are plenty of challenges related to indoor air quality in elementary, middle, and high schools, higher education institutions have additional concerns to address:

Higher education institutions face unique challenges when it comes to indoor air quality. Shared living spaces, like dormitories, increase the need to eliminate mold spores, bacteria, and viruses. Additionally, both the age of college students and the fact that many of them live on campus means that the risk of on-campus substance use is higher than in high schools, making it crucial to protect students from secondhand smoke from tobacco and marijuana.

Large public universities face even greater challenges due to high population density and large lecture halls, which create ideal conditions for the spread of airborne illnesses. Unlike K-12 schools, where vehicle pollution is concentrated at drop-off and pick-up times, universities experience constant traffic throughout the day due to varied class schedules.

Research institutions add another layer of complexity, with campus spaces generating potentially dangerous air pollutants depending on the type of research conducted. Some labs also require cleanroom conditions to ensure the integrity of their work. Addressing these factors is essential to maintaining safe and healthy environments on college campuses.

Finding the Right Filters: Standalone Units vs Integrated Air Filtration Systems

Two main ways of approaching air filtration in commercial and public buildings are integrated air filtration systems and standalone units. Regardless of what approach is chosen, building coordinators should also be aware of the difference between molecular and particulate pollution and the approaches required for each. 

To effectively combat the dual threats of gaseous and particulate pollutants, it’s crucial to understand that each requires a distinct type of filter. For particulate pollutants, which include dust, pollen, mold spores, and other solid or liquid particles, mechanical filters (such as HEPA and MERV-rated filters) should be implemented. 

To target molecular (or gaseous) pollutants (such as VOCs, odors, and smoke), which are made up of molecules too small to be captured by even the most efficient mechanical filters, activated carbon filters are more suitable. Activated carbon works through a process called adsorption, where gas molecules stick to the surface of the carbon particles. This method is highly effective for reducing harmful gases and improving indoor air quality.

Integrated Systems

Integrated air filtration systems are permanent solutions that work within a building’s HVAC system to filter out pollutants. They offer the benefit of whole-building coverage but also require more upfront investment and a more involved installation process. Key considerations for integrated systems include:

  • Choosing the right type of filtration media based on specific pollutants present.
  • Ensuring proper maintenance and replacement of filters to maintain effectiveness.
  • Coordinating installation with existing HVAC systems.

Standalone Units: Air Cleaners and Air Purifiers

Standalone units offer notable advantages over HVAC filters, particularly in their flexibility and targeted filtration capabilities. Unlike HVAC systems, which are designed to filter air across an entire building, standalone units can be placed in specific areas requiring enhanced air quality, such as classrooms, offices, or medical spaces. They are typically easier to install and maintain as they operate independently of a building’s central system. Additionally, standalone units often provide advanced filtration technologies, like HEPA filters, which can capture smaller particles and allergens more effectively than the panel filters that most HVAC units have the capacity to house. This makes them an ideal choice for addressing localized air quality concerns quickly and efficiently.

Standalone air purifiers, like the CamCleaner CC500, are portable solutions perfect for temporary spaces, classrooms without integrated HVAC systems, or when flexibility is paramount. Key considerations for standalone units include:

  • Determine if both particulate and molecular pollution are addressed.
  • Confirm the use of real, individually factory-tested HEPA filters to ensure effectiveness.
  • Identify their maintenance requirements, such as replacing filters as needed.

A Mid-Atlantic school system faced significant challenges related to indoor air quality (IAQ), particularly in aging facilities without modern HVAC systems. To address these concerns, the district worked with Camfil to implement standalone air purifiers equipped with medical-grade HEPA filters across multiple classrooms. The initiative resulted in measurable improvements in air quality, producing a 98% reduction in particulate matter. The case study highlights the importance of implementing cost-effective, portable air purification solutions in educational settings to create healthier, more productive learning environments. 

CASE STUDY: School Systems 

Combining Integrated Systems with Standalone Units

Combining integrated HVAC filtration systems with standalone air purifiers offers an effective strategy for addressing air quality challenges in areas with higher pollution levels or a greater need for clean air. Integrated systems work as a baseline solution, continuously filtering air across an entire building, while standalone units can be strategically placed in specific high-need locations, such as near entrances, high-traffic zones, or areas with vulnerable populations, by delivering more air changes per hour and filtering smaller particles out of the air. This dual approach ensures comprehensive coverage and provides an extra layer of protection against airborne pollutants.

Implementing Air Filters in Schools

Improving air quality in schools is essential for creating a safe and healthy learning environment for students and staff. One effective way to achieve this is by implementing high-quality air filters. These filters work to remove pollutants, allergens, and harmful particles from the air, ensuring a cleaner and more breathable atmosphere. With concerns about airborne illnesses and environmental contaminants, investing in air filtration systems has become a priority for many schools.

1. Assessing IAQ Needs

The first step in implementing air filters is assessing the specific needs of the school. This involves evaluating the current ventilation systems, identifying areas with poor air circulation, and understanding the unique challenges of the building. Schools in urban areas, for instance, may need filters designed to handle higher levels of outdoor pollutants, while older buildings might require upgrades to accommodate modern filtration systems.

2. Determining Placement Strategies

Once the needs are identified, schools can determine the most effective placement strategies for air filters. Filters should be installed in high-traffic areas such as classrooms, cafeterias, and hallways to maximize their impact. Depending on the products chosen, this step may be limited by the configuration of the building’s HVAC system.

3. Integrating Best Practices for Air Quality Management

Recommended best practices include combining effective filtration systems with proper ventilation to ensure that clean, fresh air circulates throughout the building. Educating staff and students about the importance of air quality helps everyone understand how their actions can make a difference. Additionally, addressing sources of indoor air pollution—such as cleaning chemicals, allergens, and outdated equipment—further enhances the overall air quality, ensuring a healthier space for learning and growth.

4. Stick to the Correct Maintenance Schedule

Maintaining and replacing high-performance air filters on the correct schedule is crucial to ensure they are functioning effectively and providing proper protection for students and staff. Lower quality air filters can become clogged more quickly with dust, allergens, and other airborne particles, reducing their efficiency and potentially allowing harmful pollutants to circulate in the air. 

When filters are clogged, it not only leads to less filtered air being delivered into the intended space but also increased resistance, which increases energy consumption as the HVAC equipment must work harder to circulate air through the obstructed filters.

By adhering to a  maintenance schedule based on the performance of the filter and not on a routine based on the number of months a filter has been inservice,  you can improve indoor air quality, reduce the risk of respiratory issues, create a healthier environment for everyone in the building, while lowering the operational cost of the HVAC systems.

5. Monitoring IAQ to Determine Effectiveness

Continually monitoring pollution levels within school environments is essential for maintaining optimal air quality. This ongoing assessment allows schools to adapt their air quality management strategies in real time, ensuring the health and safety of students and staff. Utilizing advanced sensors and air quality monitoring systems can provide precise data on various pollutants, such as volatile organic compounds (VOCs), particulate matter, and carbon dioxide levels. By analyzing this data, schools can identify trends, detect emerging issues before they become significant problems, and adjust ventilation rates or filtration effectiveness accordingly. Such proactive measures not only safeguard health but also contribute to creating a conducive learning atmosphere by minimizing potential distractions caused by poor air quality conditions.

Initial Investment vs. Total Cost of Ownership: The Value of Camfil Systems

When evaluating the cost of an air filtration system, it’s important to move beyond the initial investment and consider the total cost of ownership. While the upfront cost of a premium air filter may sometimes be higher, its superior energy efficiency and long-term durability result in significant savings over time. By reducing energy consumption and extending filter life, Camfil systems help lower operational expenses, providing an excellent return on investment (ROI).

Camfil systems are engineered for optimal energy efficiency, which directly translates to reduced utility bills. These systems use cutting-edge technology to minimize pressure drop, ensuring your HVAC systems work more effectively without overexerting energy.

HVAC Engineers Resource for Low-Pressure Drop Air Filters

Camfil experts in air filtration explain  – Why Facility Managers favor low-pressure drop HVAC filters. 

HVAC Engineers: HVAC design professionals prioritize filters with low-pressure drop to ensure adequate airflow without overloading fans. A low resistance filter means the system can meet ventilation requirements with less fan energy and without needing oversized equipment (Government Lab Sees Energy, Cost Savings From Camfil Air Filtration Systems – Air Filters for Clean Air). This improves energy efficiency and helps maintain stable indoor air quality (IAQ) by delivering design airflow even as the filter loads, all while avoiding excessive strain on HVAC components.

Facility Managers:  Facility managers are charged with keeping building operations cost-effective and reliable. They favor low-pressure drop filters because these filters lower HVAC energy bills and often have longer service life (Air Filters Case Study: Camfil Filters Provide Significant). Less resistance in the system can translate to less runtime or fan speed needed from blowers, directly cutting electricity use. Longer-lasting filters also mean fewer purchase orders and less frequent shutdowns for changes, contributing to maintenance cost savings and consistent IAQ for occupants.

Maintenance Directors:  Maintenance teams value low-pressure drop since it can correlate with longer filter life and less frequent change-outs. High-pressure drop filters clog up faster and trigger more frequent replacements or alarm conditions. By using low-drop filters that hold more dust before clogging, maintenance directors can reduce labor hours and downtime – one case showed an 80% reduction in filter change labor by switching to more efficient, lower-drop filters (Case Study: Camfil Air Filters Decrease Labor by 80% and Energy Costs by 34% at Music City Center in Nashville – Air Filters for Clean Air). Lower resistance also means fans and motors work more efficiently,  potentially extending the lifespan of equipment (belts, bearings, motors) and reducing unexpected breakdowns.

Sustainability Officers/Energy Managers:  These stakeholders are focused on energy efficiency and carbon footprint. They know that HVAC systems can account for over 50% of a building’s energy use, and around 30% of that HVAC energy is just to overcome air filter resistance (E-mobility battery cell plants | Camfil). Low-pressure drop filters directly reduce this portion of energy consumption, yielding major savings in kilowatt-hours and greenhouse gas emissions. In practice, many sites using Camfil’s low-drop filters have seen double-digit percentage reductions in HVAC energy use (e.g. 15–30% energy cost drops in hospitals) (Government Lab Sees Energy, Cost Savings From Camfil Air Filtration Systems – Air Filters for Clean Air). For sustainability programs, this means lower carbon emissions and easier achievement of energy targets or LEED credits, all while generating operational cost savings.

Environmental Health & Safety (EHS)/IAQ Professionals:  EHS and IAQ experts prioritize healthful indoor air without compromising ventilation performance. They seek high-efficiency filtration to remove contaminants but also need low-pressure drop so that airflow isn’t choked off. Filters that maintain low resistance even at high efficiency (e.g. Camfil’s fine fiber filters that hold their MERV rating over time) ensure that air quality stays high and ventilation rates meet safety standards (Government Lab Sees Energy, Cost Savings From Camfil Air Filtration Systems – Air Filters for Clean Air). Low-pressure drop is also tied to fewer filter changes, meaning less waste going to landfills and less exposure of staff to dirty filter handling – additional environmental and safety benefits. In sum, EHS professionals appreciate that low-pressure drop filters can sustain clean air levels for occupants and critical processes while also supporting energy and waste reduction goals.

Low-Pressure Drop Filtration: Real-World Success Stories

Facilities across various sectors have documented significant improvements in performance, energy use, and costs by adopting Camfil’s low-pressure drop air filtration solutions. Below are examples from hospitals, universities, EV manufacturing plants, data centers, and other critical facilities, illustrating how reduced pressure drop translates to tangible benefits in efficiency, IAQ, and sustainability:

Hospitals & Healthcare Facilities

Healthcare facilities often run large HVAC systems 24/7, making filter energy losses a big concern. Many hospitals have turned to low-pressure drop filters to balance strict air cleanliness standards with cost control. For instance, Bornholm Hospital in Denmark experienced chronic high differential pressure alarms and frequent filter changeouts. After switching to Camfil Hi-Flo XLT bag filters (optimized for low resistance), the hospital cut HVAC energy use by ~36% within four months and eliminated most pressure alarms (Major energy savings in the ventilation operation | Camfil). This equated to about DKK 20,000 (~$2,800) energy savings per year per air handling unit, plus fewer filter replacements and lower CO₂ emissions (Major energy savings in the ventilation operation | Camfil). Similarly, Camfil notes that hospitals using their low-pressure-drop filters have seen 15–30% drops in HVAC energy costs alongside extended filter life (Government Lab Sees Energy, Cost Savings From Camfil Air Filtration Systems – Air Filters for Clean Air). In a large U.S. hospital trial, Camfil’s Absolute VG HEPA filters had roughly half the initial pressure drop of a competitor’s filters (0.55″ vs 0.82″ w.g.), indicating significant energy savings for the facility (Case Study Healthcare Absolute VG). The hospital also found the Camfil HEPA filter’s service life was estimated to be twice as long (10 years vs 5) before needing replacement (Case Study Healthcare Absolute VG). These outcomes show why hospital facility engineers and EHS managers prefer low-drop, high-efficiency filters – they maintain critical IAQ inpatient areas while delivering major energy and cost reductions.

Universities & Educational Campuses

Universities and schools, with their large campuses and tight facility budgets, have also benefited from low-pressure drop filtration. A notable case is a well-known university in the Western U.S. that evaluated Camfil’s filters via life cycle cost analysis. The Camfil Durafil filter showed a 24% lower annual energy cost than a rival filter (Viledon T-60) in the same HVAC units (All case studies | Camfil). This translated to roughly $14 savings per filter per year in energy costs (All case studies | Camfil), which adds up significantly across hundreds of filters campus-wide. By adopting these filters, the university not only saved on energy but also reduced its operational carbon footprint. Another educational facility case study (“School Learns the Benefit of Fresh Air”) similarly found that Camfil’s low-resistance filters ran far more economically. In general, by lowering filter pressure drop, schools can reduce strain on older HVAC fans and improve classroom ventilation rates without expensive retrofits. The result is healthier air for students and staff and measurable savings – truly a win-win for campus energy managers and sustainability officers focusing on both air quality and cost control.

EV Battery Manufacturing Plants

EV battery production plants and other high-tech manufacturing facilities are extremely sensitive to air cleanliness and typically have energy-intensive cleanrooms and dry rooms. In these facilities, stakeholders (from facility engineers to sustainability leads) prioritize low-pressure drop filters to reconcile two critical needs:  ultra-clean air for product quality and minimal energy overhead. Clean air is essential – studies show uncontrolled particulate contamination can cut lithium battery cell yield nearly in half (E-mobility battery cell plants | Camfil) – but high filtration efficiency must be achieved. Camfil addresses this by supplying filters that keep the pressure drop low for the entire service life while still capturing microscopic particles. Many leading EV battery plants have aggressive “Net Zero” goals, so every kWh saved matters. Camfil notes that HVAC systems can be over half of a site’s energy use, and about 30% of HVAC energy is due to overcoming filter resistance (E-mobility battery cell plants | Camfil). By using long-life filters with optimized media and open pleat designs, EV manufacturers reduce that resistance, directly slashing energy draw on massive air handling units. This yields cost savings and carbon reductions at scale. For example, Camfil’s filters in battery cell cleanrooms help maintain ISO-cleanliness standards with lower fan speeds, protecting the process while trimming energy bills. Although specific savings data is often proprietary in this competitive sector, the trend is clear:  EV facilities that implement low-pressure drop air filtration solutions see significant energy efficiency gains without compromising the ultra-clean environments required for quality and safety. In short, low-pressure-drop filtration has become a key part of sustainable manufacturing in the EV industry, allowing higher yields and lower utility costs per battery produced.

Data Centers

Data centers are another critical environment where air filtration and energy efficiency go hand-in-hand. While data centers primarily focus on cooling, air filters protect the equipment from dust and particulates that can cause overheating or failures. Here, energy managers and facility teams are very sensitive to pressure drop because any added resistance in airflow means higher fan power and higher PUE (Power Usage Effectiveness). Camfil’s experience in a large multinational data center in Spain highlights these benefits. The facility was replacing pre-filters every month and final filters twice a year due to dust, and the filter system’s high-pressure drop was driving up energy use (Energy, waste & materials savings for Datacentres | Camfil) (Energy, waste & materials savings for Datacentres | Camfil). Camfil introduced a two-stage solution using low-drop filters – 30/30 panel pre-filters and Hi-Flo XLT bag filters – which have extensive media area and very low resistance (Energy, waste & materials savings for Datacentres | Camfil). This immediately extended filter lifetimes (less frequent changeouts) and cut the pressure drop in the AHUs. The results were dramatic: the data center’s annual filter spend dropped from about €50,000 to €30,000 due to reduced replacement frequency (Energy, waste & materials savings for Datacentres | Camfil), and the lower pressure drop translated into roughly €10,000 in annual energy savings on fan power (Energy, waste & materials savings for Datacentres | Camfil). In total, the site is saving ~€30k per year and also generating less waste, thanks to longer-lasting filters (Energy, waste & materials savings for Datacentres | Camfil) (Energy, waste & materials savings for Datacentres | Camfil). More broadly, Camfil reports that using “A+” energy-rated filters with low-pressure drop yields significant energy savings in data centers, lowering total cost of ownership while still keeping dust off sensitive IT hardware (How Data Center HVAC Teams Can Improve Indoor Air Quality and Cut Energy Costs with High-Efficiency Air Filters – Air Filters for Clean Air). By improving airflow efficiency, these filters help data center HVAC systems deliver the necessary cooling with less effort, which in turn means lower electrical costs and improved PUE. The outcome is a more sustainable data center operation that protects servers and saves money – a priority for facility managers and IT operations alike.

Industrial & Other Critical Facilities

Beyond the above sectors, many industrial and commercial facilities have realized the value of low-pressure drop filtration. In manufacturing, for example, a large frozen food production plant found that upgrading to Camfil filters yielded huge benefits. In a controlled test, Camfil’s 30/30 MERV 8A pre-filter + Hi-Flo ES MERV 13 final filter combo allowed the HVAC fans to run more efficiently, resulting in about $33,000 in annual energy savings for the plant (Air Filters Case Study: Camfil Filters Provide Significant). The energy savings were so substantial that the facility received a utility **rebate check effectively offsetting the filter costs (“air filters were basically free”) (Air Filters Case Study: Camfil Filters Provide Significant). Equally important, the Camfil filters lasted longer in the high-dust environment, avoiding production downtime from frequent filter changes.

Critical infrastructure sites also see performance gains. For instance, in power generation, the Auburndale Power Station in Florida replaced its turbine intake filters with Camfil’s low-pressure-drop CamPulse GTC cartridges and saw a notable improvement in output. The lower pressure drop improved the gas turbine’s power output, saving about $390,000 over three years from increased energy production efficiency (Pressure Drop, The Energy Hog | Camfil). The filters’ longer life also reduced man-hours for maintenance and cut life-cycle costs (Pressure Drop, The Energy Hog | Camfil). While a power plant is a different scenario than building HVAC, it underscores the universal principle: reducing resistance in any air system leads to major economic gains.

Even commercial public venues have similar success stories. The Music City Center – a 2.5 million sq ft convention center in Nashville – switched to Camfil Hi-Flo ES filters and was able to eliminate its pre-filter stage thanks to the product’s high dust-holding capacity. This change dropped the overall pressure in the HVAC system and reduced the Center’s HVAC energy consumption by 34% (Case Study: Camfil Air Filters Decrease Labor by 80% and Energy Costs by 34% at Music City Center in Nashville – Air Filters for Clean Air). Over a three-year span, the Center saved heavily on energy, cut filter landfill waste by using 1,000 fewer filters, and reduced filter change labor by 80% (Case Study: Camfil Air Filters Decrease Labor by 80% and Energy Costs by 34% at Music City Center in Nashville – Air Filters for Clean Air). Such results highlight that low-pressure drop = low operating cost across many facility types, from factories and power plants to arenas and office towers.

In summary, stakeholders from HVAC engineers to sustainability officers are leveraging low-pressure drop air filters to achieve their goals:  better energy efficiency, lower costs, and superior IAQ. Real-world cases from hospitals, universities, EV plants, data centers, and industrial sites consistently show double-digit percentage energy savings, longer filter service intervals, and reduced waste/emissions when high-performance Camfil filters are installed. By maintaining peak filtration with minimal airflow resistance, these solutions deliver clean air in a more sustainable and economical way – addressing the core concerns of all key stakeholders involved (Government Lab Sees Energy, Cost Savings From Camfil Air Filtration Systems – Air Filters for Clean Air) (E-mobility battery cell plants | Camfil).
