American Air Filter

American Air Filter became AAF Flanders in April 2016, when American Air Filter Co. Inc., doing business as AAF International, acquired Flanders Corp. During this transition to the become the largest air filtration manufacturer of air filtration solutions they consolidated many models and re-branded many of the filters with new model names. As an authorized AAF Flanders retailer we have a large selection of replacement filters. If you don't see your old American Air Filter model listed please let us know and we can let you know what the recommended replacement filter is.

As with all furnace, HVAC and AC filters they are interchangeable with any brand as long as you replace with the same filter size. While we don't carry the American Air Filter brand since they are now AAF Flanders, we have a large selection of replacement air filters in the same standard sizes that perform just as well if not better.

Exact Fit Furnace and AC Filters

The most important thing when replacing your filter is the size. Brands are interchangeable.

Instead of bringing in cheap restrictive filters from overseas, high priced filters because of marketing or  brands using lesser quality materials and processes like some of our competitors, our air filters are made by leaders in indoor air filtration.

Choose from MERV 8 filters designed to protect your system, capture dust and allow maximum airflow, or go as high as a MERV 13 filter to pull viruses and bacteria out of the air.
