We have looked for filters in the past and could not find the size we needed. They have every size you need. I’m going to stay with them!

So easy

These guys really got something goin here. Filters for your HVAC is way down on the thought process but very necessary. They alert you to change, the auto send when you run out. A real no brainer.

Its actually a . 25 inch smaller than the sizes stated but tbh, it fits perfectly. The true 13" was super snug trying to fit it in. Thanks!

You Refused to credit 1

You Refused to credit 1 unopened box of filters. Good business practice would have been to accept that box and/or credit new purchases, if any.

very happy with these filters! they fit great, have a very sturdy cardboard frame. The shipping was very quick. It's nice not having to go to the big box stores trying to find the size I need.

They Fit.

I had a new unit installed and the fan runs continuously. But my electric usage is down. I have four cats and one large hairy dog; live in a dusty environment and need to change filters every two weeks. The big box store was charging almost a dollar more for a MERV 5 filter and I had to bend them to get them to fit, which left gaps along the sides.
These filters fit and they cost quit a bit less than what I would have paid for a MERV 8 in store.
