Customer Reviews
Consistent quality, reliable service
This isn't my first time ordering from AirFilters.com, and they continue to deliver. I got my usual Aprilaire replacement filters, and the quality is just as good as always. In the past, I've tried other sites, but I keep coming back here because I know what to expect. My orders consistently arrive within a reasonable timeframe, typically a week to Colorado, and the filters are always correctly sized and well-packaged. I appreciate that consistency; it makes reordering a no-brainer. I've never had an issue that required customer service, which is also a good sign.
Good filters, shipping could improve
I ordered a pack of MERV 11 allergen filters for my home. The filters themselves seem to be of good quality, they fit my HVAC system perfectly and I've noticed a slight improvement in air quality since I put them in. The price was competitive, especially with the bulk discount I got. My only minor complaint was the shipping speed; it took about a week and a half for them to arrive in Texas, which felt a bit long. I understand things happen, but a slightly quicker delivery would make the overall experience excellent. Customer service was responsive when I inquired about the delay, which was a plus.
Easy to order, arrived fine
Needed to replace my furnace filter, so I hopped on AirFilters.com. Found the right size 1 inch filter quickly, the site was straightforward. Placed my order without any fuss. It showed up on my doorstep maybe 5 days later. Packaging was good, nothing was bent. Just a simple, easy transaction, which is exactly what I wanted. No complaints from me, it just worked out.
Fast delivery, correct item
Ordered custom size air filters. They arrived quickly. Filters were exactly as specified. Good experience.
Decent price for AC filters
I needed new AC filters and found AirFilters.com. I was looking for the best deal and ended up getting the 2 inch pleated air filters. The price was pretty good compared to what I'd pay at a local store. I also got a small discount for my first order which helped. Overall, I feel like I got good value for my money. It was worth buying them online.

Does anyone know if you can use a discount code AND get the subscription price? Or is it one or the other? Trying to save as much as possible lol.
Hey, thinking of getting some filters from here. Just wondering if these are like, legit brands or generic stuff? Don't want to mess up my furnace with some cheap knock-offs.
