AIR FILTRATION
WHY FILTRATION MATTERS
Harmful Particles Circulating in the Air
Filtration is an essential component of indoor air quality. Filter media physically captures airborne contaminants – from dust, pollen, and mold spores to fine particulate matter like microplastics – before they can recirculate through your HVAC system.
Filtration not only traps particles to protect the occupants, it also protects the HVAC system downstream. HEat Exchangers and AC Coils surfaces are susceptible to build-up of duct and dirt. In the dark, damp environment, this can attract growth of biofilm which impedes efficiency of the system and requires maintenance and cleaning. A well-designed filter improves comfort, protects health, and keeps systems running efficiently.
WHAT FILTRATION DOES FOR YOUR AIR — AND YOUR EQUIPMENT
High-performance air filters do more than just clean the air. They impact multiple systems at once:
Improves Air Quality: Traps particulate matter that contributes to allergies, asthma, and respiratory irritation.
Protects HVAC Systems: Keeps coils, blowers, and ductwork cleaner — improving airflow and reducing energy use.
Enhances Other Technologies: Filters out debris before air reaches UV, PCO, or humidity control components, allowing them to work more effectively.
Reduces Maintenance Costs: Cleaner systems experience less wear and require fewer service calls.
MERV-RATED FILTERS
Field Controls offers filters rated up to MERV 13, designed to capture particles as small as 0.3 microns, including:
- Pollen, dust, and pet dander
- Mold spores and bacteria
- Smoke and smog particles
- Fine debris that can damage HVAC components
These filters are ideal for homeowners seeking cleaner air to breathe and efficient HVAC performance. They also reduce maintenance and system cleaning for HVAC contractors.
HEPA FILTRATION
In specific products like portable air purifiers, Field Controls uses H13 HEPA filters, which capture 99.97% of particles at 0.3 microns — including allergens, pathogens, and other airborne threats. HEPA is best suited for:
- Portable air purification units where fans are designed to pull air efficiently through the HEPA filter.
- Occupants with allergies, asthma, respiratory illness or compromised immune system.
FLEXFILTER™ DUAL-SIZE TECHNOLOGY
A smarter filter design that simplifies installation and reduces inventory space.
FlexFilters are patented, expandable technology which reduces storage space and most expand to two different common size media cabinets. This allows contractors and distributors to:
- Cover more systems with fewer SKUs
- Reduce truck space and warehouse clutter
- Minimize trips back to the office or distributor to get the necessary size filter.
This innovative dual-size approach maintains high filtration standards while maximizing convenience — ideal for fastpaced job sites and service calls.

Standard 1-inch HVAC filters often fall short on airflow, lifespan, and particle capture. FlexFilters offer a smarter solution with expanded surface area, balanced airflow, and longer service life—helping protect your system while improving indoor air quality.
Your HVAC system moves air through your home all day long, but without proper filtration and purification, it may also be circulating dust, allergens, mold spores, microbes, and chemical pollutants. These contaminants can repeatedly cycle through your ductwork and living spaces, affecting comfort and long-term health. Understanding how HVAC airflow works and why standard filters often fall short can help homeowners take the right steps to improve indoor air quality and reduce airborne contaminants throughout the home.
A media air cleaner is a whole-home filtration upgrade that integrates directly into your HVAC system to capture more airborne particles, improve airflow, and extend filter life. Unlike standard 1-inch filters, media air cleaners use deep-pleated filters and sealed cabinets to deliver cleaner air throughout your entire home with less maintenance.
Indoor air can be up to five times more polluted than outdoor air, particularly in energy-efficient homes that are tightly sealed, allowing pollutants like germs, VOCs, and odors to accumulate over time and potentially cause health problems for residents. Learn how a whole house air purifier can help.
Your HVAC system may be circulating more than just air. Dust, mold, and bacteria can build up and impact your health. Discover how whole-home purification helps.
As temperatures drop, your furnace becomes the heart of your home. Before winter arrives, make sure it’s running efficiently and safely. From replacing filters to checking burners, these simple maintenance steps can lower energy costs, improve air quality, and keep your family comfortable all season.
