Made In The USA
All air filters are manufactured by FilterBuy in the USA using 100% American made components. By purchasing directly from the manufacturer, you’re saving big on a premium product.
High Quality
11.25x11.25x1 pleated air filters are at least 20 times more efficient than fiberglass filters. Filter frames are made of beverage board, which stays strong through humidity and temperatures up to 200° F. Synthetic media provides significantly higher particulate efficiency than standard cotton media.

Excellent service
Somehow I received the wrong size air filters. The company graciously sent me, at no charge, the correct size and did not ask for the other filters to be returned. I donated them to Habitat for Humanity ReStore. Good work.

Is it Time to Change Your Filter?
Generally, we recommend you replace your air filters every 90 days. Find out below if you should change your filters more often.
If someone in your home has asthma and/or allergies...
Change your filter every 6 weeks to ensure indoor air quality is at its best.
If you have pets...
Change your filter every 2 months to avoid shedding and odor buildup.
If you have young children...
Change your filter every 2-3 months, as having clean air is even more important with children in your home.
Simply measure the length and width of your filter with a tape measure and choose the closest size
(to 1/8”) in the drop down menu. 1/8” tolerance is standard and should not cause a problem in any
standard filter application.
Please note that the ‘actual’ filter size, ie the size that your tape measure shows, should be used when
creating a filter with this tool, not a nominal filter size. Note that the depths of each filter are
standard, as shown to the right.
