Whole House Air Filters are also known as Residential Air Cleaners, Media Filters, and Whole House Air Cleaners. They all perform identically to protect your HVAC system, remove particles from the air, and improve indoor air quality. These large filters function just like 1-inch filters, but only need to be changed every 6-12 months because of the greater surface area. Also, they offer a much higher airflow rate due to the increased filtering media. We have a large selection of OEM brand names and quality lower-cost aftermarket options. Select your brand name below to view your options. Or, if you already know your model# (from the filter or filter housing), you may enter it at the top right of this page in our keyword search to go directly to your filter!
