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).

The Environmental Impact of Air Filters: Balancing Indoor Air Quality with Sustainability

Maintaining indoor air quality is more than just a health necessity—it’s an environmental responsibility. Clean air contributes to cognitive health, enhances productivity in schools and workplaces, and improves overall well-being. However, while air filters play a crucial role in ensuring cleaner air, their environmental impact—both positive and negative—must be carefully considered.

Can choosing the right air filters help reduce a building’s carbon footprint? How can we minimize waste while maintaining good indoor air quality? Let’s explore these critical questions.

The Positive Environmental Impact of Air Filters

Reducing Indoor Air Pollution

Not all air filters are created equal. To improve indoor air quality (IAQ) and protect building occupants, health authorities in the U.S. and Canada recommend using air filters rated at least MERV 13. The ASHRAE 52.2 test standard requires a MERV 13 filter to capture at least 85% of particles in the 1 to 3-micron range—the sizes which are particularly harmful to human health.

High-quality air filters significantly improve IAQ by reducing these particles which are linked to respiratory diseases, allergies, and other health concerns. According to the Environmental Protection Agency (EPA), indoor air can be up to five times more polluted than outdoor air, making effective filtration essential.

Energy Efficiency and Carbon Footprint Reduction

Air filters designed for energy efficiency and longer lifespan can substantially lower environmental impact. Filters with a low average pressure drop over their lifespan result in reduced:

• Energy consumption when used with variable frequency drive (VFD) fans
• Waste generation from frequent replacements
• Greenhouse gas emissions during production and transportation

By integrating high-quality filters with VFD-controlled HVAC systems, buildings can lower energy consumption and significantly reduce their carbon footprint.

Protecting HVAC Equipment and Reducing Maintenance

Air filters also extend the lifespan of HVAC systems by preventing contaminant buildup on coils and ductwork, maintaining optimal airflow, and reducing wear and tear. This translates to lower maintenance costs, fewer hardware replacements, and reduced material waste.

Preventing Nuisance Odors and Pollutant Gases

Specialized air filters help control odors and pollutant gases in industrial settings, such as:

• Cannabis production facilities (preventing odors from affecting nearby communities)
• Gas plants and waste treatment facilities (protecting workers from harmful emissions)
• Pulp and paper production facilities (reducing air contaminants in industrial zones)

The Negative Environmental Impact of Air Filters

Increased Waste from Low-Quality Filters

One of the biggest environmental concerns is the sheer volume of waste generated by disposable air filters. Many low-quality filters load with particulates too quickly, leading to frequent replacements and increased waste sent to landfills.

Additionally, non-recyclable filter components, such as dirt-loaded media, contribute to landfill overflow. However, some filter frames made from plastic or metal can be recycled, helping offset waste.

Poor Air Quality from Ineffective Filters

Using improperly rated, low-quality, or damaged filters leads to poor indoor air quality. This can negatively impact workplaces, schools, healthcare facilities, and public buildings, increasing health risks for occupants.

Many substandard filters lack evidence of following ASHRAE 52.2 with Appendix J testing procedures, which produce a filter’s MERV-A value. Lacking this MERV-A value means it’s questionable if the filter will maintain the original MERV value for the entire service life.  Poor filtration increases airborne pollutants, leading to greater respiratory illnesses and energy consumption, as HVAC systems work harder to compensate.

Solutions for Reducing Air Filter Waste

Choose High-Efficiency, Long-Lasting Filters

For sustainable air quality management, it’s best to use a minimum of MERV 13-A or the highest MERV-A rated filter the system will handle. These filters:

• Maintain efficiency over time, unlike low-cost filters that degrade quickly
• Last longer, reducing replacement frequency and waste
• Operate with less energy, minimizing carbon emissions

Low-quality pleated filters often need replacement every three months, whereas premium pleated filters can last nine months to a year or more.

Camfil’s Commitment to Reducing Waste

Camfil is at the forefront of air filter sustainability, focusing on:

• Longer-lasting filters that minimize replacements
• Recycling initiatives to repurpose filter components
• Energy-efficient designs to lower operational costs

For example, certain commercial air filters by Camfil now last up to five years, dramatically reducing waste output. Additionally, filter media can be removed for recycling, and plastic or metal frames can be repurposed for new products, such as park benches.

Converting Air Filter Waste into Energy

Non-recyclable air filter components can be safely combusted to generate energy. When combined with scrubbers to capture harmful emissions, this process can:

• Convert waste into usable energy
• Reduce landfill dependency
• Lower overall environmental impact

The Future of Sustainable Air Filtration

As air filtration technology evolves, the focus remains on innovation, sustainability, and efficiency. Advancements include:

• Enhanced filter designs for maximum efficiency and recyclability
• Improved materials that extend filter life and reduce waste
• Smart HVAC integration for optimized energy use

How Data Center HVAC Teams Can Improve Indoor Air Quality and Cut Energy Costs with High-Efficiency Air Filters

The data center industry is experiencing significant growth due to the increasing demand for cloud computing services, Internet of Things (IoT) devices and especially artificial intelligence (AI) technologies. As businesses continue to adopt cloud services, they are relying more on external data centers to host their data and applications, leading to a greater demand for larger data center infrastructures.

The surge in data generated by IoT devices, big data analytics, AI and machine learning requires more robust storage and processing power, resulting in an increase in the number of data centers. By 2030, it’s projected that AI workloads will account for approximately 70% of data center capacity, contributing to a projected 160% increase in power demand. 

Additionally, edge computing, which brings computation and data storage closer to the source of the data, is driving the establishment of smaller, localized data centers. These smaller sites are well-suited for 5G networks, which require ultra-low latency by processing data closer to the end user. 

However, the expansion of data centers poses several challenges, particularly concerning rising energy consumption. Data centers need vast amounts of energy to run servers and maintain cool environments, which could potentially double or triple energy loads from data centers in the U.S. by 2028, further escalating energy consumption. 

As data centers become larger and more complex, managing indoor air quality (IAQ) becomes vital to protect equipment and staff health as well as controlling energy consumption. For example, controlling dust accumulation on sensitive equipment is important to prevent overheating and ventilation issues, which impact equipment longevity, personnel health, sustainability and energy usage.

While proper ventilation is essential for maintaining good indoor air quality, increasing ventilation to improve IAQ can lead to higher energy consumption. Modern HVAC systems utilizing high-efficiency air filters, such as those rated MERV 13A to 16A, are capable of capturing particulate matter, dust and even bacteria, to improve data center air quality without increasing energy usage. 

In fact, as high-efficiency air filters capture more particles, they reduce the buildup of dust and debris on HVAC system components like coils and fans. This allows the system to operate more efficiently. Less dust accumulation means the system doesn’t have to work as hard, which can lower energy consumption and extend the system’s lifespan.  

The Role of HVAC Filtration in Data Centers

Who is Responsible for the Quality of the Air Inside the Data Center?

In large data centers, the selection of HVAC filters is typically the responsibility of several key roles, which may vary depending on the organization’s structure. These include:

• Facility Manager or Building Engineer: This staff member is responsible for the overall operation and maintenance of building systems including HVAC. The individual coordinates the maintenance, operation and upgrades of HVAC systems, ensuring filters are appropriately selected to maintain optimal air quality and system efficiency.
• HVAC Technicians: These specialists focus on the technical aspects of HVAC systems and filter selection. They design, plan and specify filters for the data center while considering airflow, pressure drop, filtration needs and HVAC operation. 
• IT Infrastructure Manager: This manager oversees data center operations and collaborates with facility managers and engineers to ensure that the chosen HVAC and filtration system meets the cooling, IAQ and energy consumption requirements of the data center. 
• Procurement Manager: Responsible for acquiring materials and equipment for the data center, this manager handles the purchase of HVAC filters once they are specified by engineers or facility managers
• Environment Health and Safety Manager: Focusing on ensuring air quality and fair working conditions that comply with regulatory standards, this manager ensures that filters meet health, safety and environmental regulations to prevent particulate contamination.

In large data centers, ensuring optimal environmental conditions for sensitive IT infrastructures often requires close coordination among various departments. This collaboration focuses on selecting an HVAC system, including filters, that maximizes efficiency, reduces downtime, and ensures optimal conditions for the sensitive IT infrastructure.

In smaller data centers, a more compact team manages HVAC filter selection, typically involving the facility manager and HVAC technician, along with:

• Data Center Manager: In smaller facilities, the data center manager may oversee both IT and infrastructure aspects, working closely with HVAC specialists to choose the right filters for effective cooling and airflow.
• IT Manager: While not directly responsible for the HVAC system, the IT manager may be involved in filter selection, especially if the HVAC system affects server performance or if specialized cooling is needed for sensitive equipment.

Regardless of the size of the data center, successful filter selection requires a collaborative effort based on specific requirements of the space, cooling needs and energy efficiency objectives.

Why HVAC Filtration in IT Environments Is Critical 

Maintaining an optimal operating environment is crucial to the performance, security and efficiency of data centers. HVAC systems play an important role in ensuring air quality and effective filtration, which helps maintain clean air and prevents contaminants from entering the data center. 

Particulate matter in data centers can originate from various sources such as outdoor air pollution, diesel-powered backup generators and servers. Volatile organic compounds (VOCs) are also a concern. Emitted from overheated servers, these compounds may contain harmful chemicals that can damage sensitive equipment and pose health risks to personnel. 

Trapping harmful particles through HVAC filtration is essential for data centers for several reasons.

• Protecting IT infrastructure from Airborne Contaminants. Dust and particulates can obstruct cooling systems and accumulate on sensitive equipment, resulting in reduced efficiency, overheating and damage. Effective HVAC filtration in IT environments prevents these contaminants from entering the environment where critical IT equipment operates to improve data center air quality. 
• Enhancing System Efficiency and Uptime. Poor air quality and contaminants can cause downtime or hardware failure. Robust HVAC filtration ensures that clean air is circulated, reducing the risk of dust and particulate matter affecting sensitive equipment. Additionally, proper filtration minimizes the need for frequent maintenance of both HVAC systems and data center hardware. 
• Improving Energy Efficiency and Reducing Power Consumption. HVAC systems equipped with efficient filtration optimize airflow, which enhances the performance of cooling systems. Without proper cooling, temperatures can quickly rise, potentially causing equipment damage or system failures. To compensate for inefficient cooling, HVAC systems must work harder, leading to increased energy consumption. Effective filtration helps HVAC systems operate optimally, controlling overall energy use. 
• Preventing Health Issues. Filtering out allergens, contaminants and bacteria contributes to maintaining clean and safe air for staff working in the data center. 
• Maintaining Compliance with Industry Air Quality Standards. Effective air filtration ensures that data centers meet the required air quality and environment standards for compliance and safety. Many data centers operate under strict cleanroom standards that limit airborne particles. HVAC systems equipped with high efficiency filters help meet these standards. 

Challenges in Data Center IAQ and Energy Consumption 

Poor IAQ Is a Problem

Data centers are highly sensitive to their environmental conditions. Poor data center air quality can negatively impact the performance, efficiency and reliability of sensitive equipment, including servers, storage systems and other components. When staff enters the space, impurities from their clothing can be introduced. Additionally, outdoor air pollution and dust can infiltrate data centers and server rooms through ventilation systems. 

Research conducted by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) highlights that dust and particulate contamination are primary concerns for data centers. Even small amounts of dust, dirt and other particulates can pose significant risks to this equipment.

For instance, the accumulation of dust and particulate matter on sensitive devices, fans and filters can hinder their proper operation, leading to system slowdowns. Additionally, certain pollutants, such as high levels of VOCs, can accelerate corrosion of metal electronic components in hardware. 

Data centers rely on controlled environments to maintain optimal temperatures for IT equipment. If airborne contaminants are not captured by filters, they can clog ventilation systems, reducing airflow and cooling efficiency. Clogged cooling systems increase the risk of equipment overheating, which leads to processing malfunctions or failures. In addition, cooling inefficiencies can damage or cause short circuits, resulting in maintenance costs and operational downtime. Unplanned IT downtime can cost anywhere from $5,600 to $9,000 per minute, depending on the company.

An inefficient cooling system also requires more energy to maintain proper temperatures. This increases energy consumption, operational costs and the environmental footprint for the data center. Cooling inefficiencies caused by IAQ issues can increase energy consumption.

Rising Energy Consumption

Data centers are very energy-intensive, consuming 10 to 50 times more energy per floor space than a commercial office building. As noted earlier, AI-driven workloads are growing and will significantly elevate data center energy demands. Goldman Sachs estimates that data center power demand will grow by 160% by 2030. While data centers worldwide currently consume 1%-2% of overall power, that figure is projected to rise to 3%-4% by the end of the decade due to AI advancements. 

While data center power demand remained stable despite increased workloads between 2015 and 2019 due to improved efficiency, power consumption has increased since 2020. This trend is expected to continue with the rise of AI, as a single ChatGPT query requires 2.9 watt-hours of electricity compared to 0.3 watt-hours for a Google search. According to McKinsey analysis, the United States is expected to be the fastest-growing market for data centers, with demand rising from 25 GW of demand in 2024 to more than 80 GW in 2030. 

While the majority of energy consumed in a data center is used to power computer hardware, the energy required for the HVAC systems can be a close second. As data centers expand, the need for energy-efficient HVAC solutions becomes increasingly important. Unfortunately, many data centers still utilize inefficient air filtration methods, leading to higher energy usage. Older, traditional data centers often depend on basic HVAC systems equipped with standard filters for cooling and air filtration, which are not optimized for energy efficiency or air quality. In environments with high dust levels, standard filtration solutions may be inadequate. Additionally, areas with significant pollution and humidity can exacerbate filter clogging, further diminishing system efficiency. 

If air filters fail to capture fine or specific contaminants, they can become clogged and restrict airflow. As a result, the HVAC system must work harder to maintain adequate airflow, resulting in increased energy consumption and higher electricity bills.

For example, a data center situated in a heavily urbanized area with significant traffic may experience filter clogging due to dust and other particulates. This forces the HVAC system to work harder, increasing electricity costs for ventilation and cooling. Ineffective filtration also can lead to pollution accumulation in the data center, adversely affecting hardware and increasing maintenance needs. Implementing high-efficiency filters can help alleviate these issues and reduce excessive energy use.

Air Filtration Solutions for Data Centers

Benefits of High-Efficiency Filters 

Today’s advanced HVAC systems use high-efficiency air filters to improve both data center air quality and energy performance. These filters effectively remove a significant percentage of airborne particles, resulting in cleaner air that improves airflow and reduces the load on air conditioning systems. High-efficiency filters with low pressure drops achieve a balance between effective filtration and low resistance to airflow that can reduce energy consumption while improving system performance

In some cases, HEPA filters, capable of capturing a minimum of 99.97% of particles as small as 0.3 microns, are required to remove the smallest contaminants from the air. However, because these filters with very high filtration efficiency tend to have higher pressure drops, data centers may opt to use a combination of filters in their HVAC systems to achieve several benefits:

• Energy Savings for Data Centers: Energy-efficient filters prevent air handlers from working harder to push air through clogged or inefficient filters. This reduces energy consumption and operating costs in data centers. 
• Greater system efficiency:  High-efficiency filters enhance the overall efficiency of HVAC systems, allowing for smoother air circulation. By decreasing airflow resistance, less energy is required for cooling that results in energy cost savings. 
• Enhanced IAQ: High-efficiency filters trap a range of fine particles including dust, dirt and other contaminants to maintain high levels of air quality and prevent contaminants from entering the data center. Clean air is important for the optimal performance of servers and other sensitive hardware. 
• Improved Cooling Efficiency: These filters help prevent dust and particles from accumulating on cooling systems, ensuring they function at peak performance. 
• Extended Equipment Lifespan: Reducing airborne dust and particulate matter helps prolong the lifespan of HVAC components and IT equipment. This results in fewer repairs and replacements, which reduces maintenance costs, minimizes downtime and lowers labor needs. 

• System Performance: The selected filters must balance the filtration efficiency with the pressure drop to avoid negatively impacting the HVAC system’s airflow and energy consumption.

Categories of Air Filters 

A variety of high-efficiency filtration methods are available, each designed to remove different types of contaminants at varying efficiencies. Air filters are selected based on the specific needs of the data center environment. It’s common for data centers to require various levels of air filtration efficiency for different areas and applications. Below are three general filter categories based on performance. 

• MERV (Minimum Efficiency Reporting Value) Filters: These filters are rated according to their ability to trap small particles. Ideally, data centers should use air filters with a MERV rating between 13 and 16 and labeled with a MERV-A rating. Filters indicating their MERV A value means they will maintain that efficiency value for their entire service life.

MERV filters are frequently used in data centers as they can balance the filtration efficiency with pressure drop to avoid negatively impacting the HVAC system airflow and energy consumption. These filters are usually installed at the air intakes for cooling systems to capture air contaminants as air circulates through the system. Ventilation systems in data centers and server rooms can circulate and replace air 30 to 50 times per hour, compared to an average commercial office exchange rate of only two to six times per hour. Different types of MERV filters have unique advantages and efficiencies. Often, these filters are used in combinations to address different requirements. 

• High-Efficiency Particulate Air (HEPA) Filters

HEPA filters are highly efficient at trapping very small particles, capturing 99.97% of particles as small as 0.3 microns. Made from dense layers of micro-glass fibers, they are an excellent choice for improving data center air quality under the right conditions.

Although HEPA filters are not energy efficient and tend to be more expensive, they can be used in conjunction with other MERV filters as part of a comprehensive filtration system.

• Molecular Filters

Gases are composed of particles that are so small, they are better thought of as molecules. In fact, they are so small, they can easily pass through the most efficient HEPA filters. Gaseous contaminants can accumulate on electrical components and cause corrosion damage that can cause downtime if not recognized and corrected in time.

Capturing gases requires specialized filters known as molecular filters, sometimes referred to as carbon filters. These filters remove harmful gases, VOCs and other odor-producing chemicals from the air using a filtration process known as adsorption. Identifying the gases present enables the selection of the most effective carbon media for controlling them.

Comparison of Traditional filters vs. Camfil High-Efficiency Filters

Traditional filters typically have lower filtration efficiencies, often with MERV ratings between 8 to 13. They are often constructed of thick synthetic fibers to keep manufacturing costs down. Coarse synthetic fibers often require an additional electrostatic charge added to achieve the desired MERV value, which can degrade over time. This reduction in efficiency can cause the MERV value to drop below its original rating and below what the facility requires. Designed primarily for basic HVAC systems where airflow is prioritized, these filters are often used for general air filtration and may not meet the specific needs of critical applications. Although traditional filters are affordable initially, they can cost more over time due to frequent replacements. Using low-quality air filters in a data center ventilation system results in up to a 30% drop in efficiency over the entire system. 

In contrast, Camfil air filters are engineered for higher efficiency, targeting smaller particles such as fine particulate matter and bacteria. They utilize energy-efficient materials, including fine fibers as opposed to coarse fibers and advanced composite materials, which create media that combine high filtration efficiency with strength and resistance to chemicals and temperatures. Filters that utilize fine fibers can be classified under the MERV A rating system, which indicates the filter will maintain its original MERV value. For air filtration systems designed to remove gases, odor and VOCs, Camfil uses a wide range of activated and impregnated carbon and other media.  The company’s focus on low-emission materials leads to reduced carbon dioxide emissions.

Camfil air filters are designed to minimize airflow resistance while maximizing filtration efficiency. They are used in critical environments such as data centers, healthcare facilities, cleanrooms and industrial applications. By installing Camfil’s 5-star air filters in existing air ventilation systems, organizations can reduce energy expenditures by up to 40% through improved airflow.

The Future of Energy Efficient IAQ in Data Centers

The future of air filtration in data centers will be influenced by growing demands for energy efficiency, improved sustainability and ongoing technological advancement. Since data centers are among the largest consumers of energy, IAQ will significantly impact energy efficiency and sustainability. As the demand for data grows, data centers will face more pressure to operate more efficiently. 

High-efficiency air filters, such as MERV A-rated filters, will be essential in capturing airborne contaminants to reduce load on HVAC systems and lower cooling energy requirements. These filters also will contribute to healthier working environments and help minimize the carbon footprint of data centers. 

Camfil supports current and future energy efficiency goals with filters designed to minimize air restriction while maintaining high air flow and efficiency in capturing airborne particles. These air filters reduce pressure drop so less energy is required to circulate air through the system. They also ensure cleaner air for healthier and more productive data center environments. In addition, the use of sustainable materials, innovative technologies and proprietary processes enables the development of filters that use less material and last longer, generating less waste while achieving high filtration efficiency.

The growth of digital data will increase the number of data centers and the volume of data processing within these facilities. This surge heightens the importance of maintaining superior indoor air quality to protect equipment, optimize operations, ensure safety and control energy consumption.

Air Quality May Impact Aspects of Emotional Intelligence, According to New Study

Air pollution has long been recognized as a leading environmental health risk, causing respiratory and cardiovascular diseases. But recent research sheds light on another critical, lesser-known impact—its effect on brain health, specifically cognitive function and emotional intelligence. This blog explores the science behind these findings, the implications for mental health, and practical tips for managing air quality in personal and professional environments.

The Basics of Air Quality

Air quality refers to the degree of pollution present in the air, influenced by factors such as emissions, weather conditions, and natural disasters.

Air pollution can broadly be categorized into two types: molecular (or gaseous) and particulate. Molecular pollutants include gases such as carbon monoxide (CO), sulfur dioxide (SO₂), nitrogen oxides (NOₓ), and volatile organic compounds (VOCs). These gases are often emitted from industrial processes, vehicle exhaust, and the burning of fossil fuels. They can have significant effects on respiratory health and contribute to issues like smog and acid rain.

Particulate pollutants, also commonly referred to as particulate matter or particle pollution, consist of tiny solid particles or liquid droplets suspended in the air, known as particulate matter (PM). They are typically classified based on their size: PM10 (particles with a diameter of 10 micrometers or less), PM2.5 (particles 2.5 micrometers or less) and PM1 (particles 1 micrometer or less). Particulate pollutants can originate from sources like construction activities, wildfires, and industrial emissions. These particles are particularly concerning as they can penetrate deep into the lungs and even enter the bloodstream, posing serious health risks.

Understanding these two types of pollution is essential for developing effective strategies to improve air quality and protect human health.

Study Shows Air Pollution Impacts on Cognitive Processes, Including  Ability to Recognize Emotions

A 2025 study published in the peer-reviewed journal Nature Communications (2025) exposes the correlation between air pollution and diminished cognitive capabilities.

Cognitive function refers to various mental processes essential for daily activities. Supermarket shopping is a great example of how these functions work independently and together. Executive function, particularly selective attention, helps with decision-making and staying focused on your shopping list while ignoring distractions and avoiding impulse purchases. Working memory acts as a temporary space for holding and processing information, like comparing prices or brands to make smart choices. Socio-emotional cognition allows us to recognize and understand emotions, ensuring smooth social interactions and appropriate behavior while shopping. These cognitive skills, while distinct, operate in harmony to complete everyday tasks. Examining each function individually helps identify which are most affected by air pollution, paving the way for targeted interventions and strategies to build resilience.

The study involved exposing participants to high levels of particulate matter and tracking their cognitive and emotional responses four hours later. Conditions were blinded (meaning that study participants did not know which air quality conditions they were exposed to) so that knowledge or perception of air pollution exposure didn’t confound results. Findings showed impairments in key brain functions:

• Selective attention – the ability to focus on specific tasks while ignoring distractions.
• Emotion recognition – the capacity to interpret and respond to emotional cues in the environment, such as the ability to

Selective Attention

Selective attention is the ability to focus on specific stimuli for further processing while ignoring irrelevant or distracting inputs. Distractions can come from external sources, like background noise or visual clutter, or internal ones, such as wandering thoughts or habitual responses that interfere with the task at hand. Selective attention is essential for complex analytical tasks, such as learning a new language or solving math problems, but also for basic daily tasks, such as choosing what to eat or engaging in conversation.

In the study, selective attention was measured by assessing participants’ reaction time (RT) in seconds. The change in reaction times (before exposure to either the clean air condition or the pollution condition and after exposure) was analyzed, and researchers found a statistically significant increase in reaction time (indicating a decrease in selective attention) under the pollution condition, and a statistically significant decrease in reaction time (indicating an increase in selective attention) after exposure to clean air. On average, post-exposure reaction times in the pollution condition group were 10 milliseconds slower than in the clean air group.

Emotion Recognition

In the study, researchers focused on emotion discrimination, which is the ability to identify and distinguish emotions conveyed through facial expressions, sounds, body language, and other signals. Emotion discrimination is a critical skill for effective social interaction and communication. Being able to accurately identify and interpret emotions allows individuals to respond appropriately to others’ needs, fostering empathy and strengthening relationships. This skill is particularly important in collaborative environments, where understanding emotional cues can help to de-escalate conflicts, build trust, and enhance teamwork; therefore, it is crucial in both personal and professional relationships.

The study found that acute exposure to PM pollution significantly impaired participants’ ability to recognize emotional expressions compared to clean air exposure, as indicated by a larger performance decline post-exposure. Though a significant main effect of session time was found (meaning that participants’ emotion recognition was generally better the first time it was tested), the decline in performance under the clean air condition was not found to be statistically significant.

Implications of the Study’s Results

Other functions, such as working memory, showed resilience to short-term pollution exposure. This suggests varying vulnerabilities within our brain functions—an area ripe for further exploration.

The authors propose two potential mechanisms for these effects:

1. Direct pathway — Particulate matter may directly reach the brain through the olfactory system or cross the blood-brain barrier.
2. Indirect pathway — Systemic inflammation triggered by lung exposure to pollutants may harm brain tissue over time.

These findings underscore the pressing need to address air pollution and its multifaceted impact, particularly in urban environments with high PM2.5 levels.

Managing Air Quality for Health and Well-Being

Fortunately, not all is lost. Understanding and mitigating the influence of air quality on brain health can empower individuals and institutions to protect themselves. Here are actionable steps to improve air quality and safeguard your cognitive and emotional well-being:

1. Monitor Air Quality Levels

Sources such as AirNow.gov provide real-time air quality updates based on aggregated data from thousands of air quality monitors across the United States. Individuals can use these services to plan activity for times when pollution levels are lower. 

2. Ask Facility Managers Questions  

Concentrations of air pollutants can be up to fifty times higher indoors than in the surrounding outdoor area. Ask your employer or facility manager at your school if they’ve appointed a CAO, Chief Airgonomics Officer. This is the person in an organization with the responsibility to ensure all reasonable steps are being taken to protect the occupant’s health from poor indoor air quality.  During extended breaks, for example, it’s not unreasonable to ask the facility manager to explain what steps are taken to maintain acceptable indoor air quality. 

3. Minimize Exposure During High Pollution Events

Avoid outdoor exercises or strenuous activities near high-traffic areas during times of increased pollution, like wildfires or smoggy days.

4. Make Ventilation a Priority

To improve indoor air quality, facilities managers can collaborate with Camfil’s air quality specialists to monitor indoor air quality and determine specific focus areas for improving it. 

Here are measures that can be integrated into building strategies:

• When planning new construction, include in the design advanced HVAC systems with the capability to provide high indoor air quality. For existing systems, educate yourself on its capabilities and select air filters that deliver the optimal filtration solution for your facility.
• Work with a quality air filtration supplier who can assist you in developing the appropriate maintenance schedule.  
• Educate employees about air pollution’s effects and mitigation strategies and encourage open dialog.

Watch Video: Understanding Airborne Pollutants in Data Centers

Particulate Matter vs. Molecular Contaminants

Air pollution comes in two main forms:

Type	Description	Common Examples	Filtration Solution
Particulate Matter (PM)	Solid or liquid particles suspended in air	Dust, dirt, soot, PM1,  PM2.5, PM10	HEPA & MERV A-rated filters
Molecular Contaminants	Gaseous pollutants, much smaller than PM	Ozone, nitrogen dioxide, sulfur dioxide	Molecular filtration (adsorption)

Why Molecular Contaminants Matter

While traditional air filters can capture dust and airborne particles, they cannot remove molecular contaminants. In data centers, these gases accumulate undetected, accelerating corrosion and increasing the risk of equipment failure.

3. How Corrosion Damages Electronic Equipment

Watch Video: The Hidden Dangers of Corrosion

What Is Corrosion?

Corrosion occurs when reactive gases interact with metal surfaces, forming oxidation layers that degrade electronic performance.

A well-known example is the Statue of Liberty, which is slowly turning green due to copper corrosion over decades. In data centers, this process happens much faster, potentially within months!

How AirImage-COR Measures Corrosion Risk

The AirImage-COR assigns a G-Rating based on the severity of corrosive gas exposure:

Rating	Corrosion Risk	Impact on Equipment
G1	Minimal risk	No immediate action needed
G2	Gases detected	Source should be identified
