Great buys

I’ve been buying my filter for these guys for the last six months. Delivery is super quick. Price is greatly, just as good as the products in the big box stores for less price. Do yourself a favor and give them a try.

Too Short
on September 12, 2026
Posted by: Customer
Filters are too short. I purchased the 14x24x1 and they aren’t 24 inches in length, they are just barely 23. 5, I have pictures to prove it. Air ducts make sucking noise every time the air comes on. Drives us nuts. Will buy Filtrere air filter in the future because they fit.
