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 DuPont and Accumulair (Carbon, Diamond and Titanium). 

Please expect 5-10 business days for custom orders to ship. 

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