The search is over.

For over 23 years, I have searched for those little 14"squares. I had to resort to those green things you cut to size, and it wasn't until my fairly new furnace blew a breaker, and the repair guy showed me the filters...the bathroom 14" was not right and let a lot of dust into the ducts. I had a crew come and clean the ducts, and they discovered the damage. Now I have the proper filter that actually catches dirt...and I learned they need to be replaced at least every 3 months. This house is dusty, and you saved me from any further problems.

I like the filters.

I like the filters. They were delivered quickly and do a good job job of cleaning up my air. The best, though, is the site. It gave me information that I needed to decide what to buy. It was easy to follow the explanation.

These air filters are great and easy to install and change. Its hard to find this size in any stores they always have to special order them. So with this being said I just purchased mine from your company and the price is excellent.

Took a few days to get, but they are what I expected. Seem to be of good quality, time will tell. They do seem to fit the return a little looser then the ones I had from big box store
