Customer Reviews
Good filters, delivery took a bit
I ordered a few MERV 11 allergen filters, specific size 20x25x1. The website was easy to navigate to find what I needed. Placed the order, got a confirmation email right away. Shipping said 3-5 days, but it took about 7 days to reach me in California. The filters themselves were well-packaged and seem to be good quality, no damage. They fit my HVAC unit fine. Haven't had to contact support, so can't speak to that. Overall, decent experience.
Perfect custom size AC filter!
My AC unit has this weird size filter, and I always struggle to find them. AirFilters.com literally saved me! I got a custom size air filter, 18x23x1, and it arrived much faster than I thought it would for a custom order. It fit like a glove when I put it in. The quality felt really sturdy, not flimsy at all like some I've gotten before. I'm so happy I found this site; it makes getting filters so much less of a headache. I'll definitely be back for more filters next season!
Easy to find filters
Needed some new MERV 8 pleated air filters for my furnace. Found the size quick and ordered a 4-pack. They shipped fast, got to me in about 4 days. Fit perfectly, no issues.

Hey, thinking of ordering some furnace filters from here. Are these guys legit? Like, are the filters good quality or just some cheap knockoffs?
Anyone know if you can stack coupons here? Got a 10% off for signing up for emails, but also found a code for like 15% off for bulk orders. Can I use both?
