Create Your Custom Air Filter

AC units and furnaces are not a one-size-fits-all commodity. Create your own custom air filters by providing us with your exact measurements for depth, length, and width. Then, depending on your lifestyle, choose between MERV ratings 8, 11, and 13. We find MERV 11 to be best for pet owners and MERV 13 for those with allergies or asthma. If you aren't sure what's best for you and your family or office, check out our MERV guide, or see below for comparisons between energy savings and filtration efficiencies. Once you know your measurements and MERV rating preference, let us know how many custom filters you want delivered right to your door, and we will get them to you with free shipping, no minimums.

Nominal Depth Actual Depth
1 ¾"
2 1¾"
The minimum size is 5" x 5" and the maximum is 40" x 40".
Please Note: Due material limitations used to build a custom filter, we construct a double filter (two filter fused together) when any filter dimension is larger than 24.75" on both sides and or larger than 29.75" on one side.
