Air filters trap particles like dust and mold spores before they enter the air you breathe; keep your family healthy by changing your home air filters on a regular basis.

When replacing a new filter, flush about 2 gallons of water through the filter before drinking the water. This will eliminate any carbon particles leftover from the manufacturing process.

Affordable Air Filters Delivered to your Door

Few things are as important as indoor air quality when it comes to protecting your family's health. By installing the right air filters, you can keep the air in your home free of airborne particles like dust, pollen, mold spores and dust mite debris. A quality air filter will even keep your HVAC system running at peak efficiency through improved air flow. We sell air filters from premier brands like Trion, Trane, GeneralAire, Space-Gard, Skuttle and White-Rodgers.

Our product pages show you air filter images, as well as performance specifications, compatibility information and Minimum Efficiency Reporting Value (MERV) ratings. MERV ratings were developed in the 1980s by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). Ratings on a scale of 1 to 16 serve as indications of how a filter will perform. Average residential air filters typically range from MERV 1 to MERV 4. Filters are able to capture smaller particles � and generally last longer � as the MERV rating increases.
