Custom Air Filters

Can't find your filter size you need off-the-shelf (you can double check by searching for at top right of this page)? For many applications, custom air filters are required for the furnace or AC unit. We proudly feature custom 3M Filtrete and Accumulair (Carbon, Diamond and Titanium). 

 Need your custom filters fast? We build and ship these custom sized air filters within 3 business days of ordering!

Please note: Custom filters are not eligible for returns/exchanges/refunds since they're uniquely-prepared.
