Great filters

Found exactly what I needed for my furnace. Can't find these in a regular home improvement store. Just bought my home and needed new filters and this was in it and I got the information off the old filter and looked this site up and found my replacement very easily. Recommend this site and very fast shipping also.

Your filters were substantially inferior to the filters that I had previously used. I am so disappointed and will never buy them again. I wish I had not purchased in bulk. 😢

The filters are great but how often am I supposed to change them? I received another box of them and haven't finished using the first box. My filters look brand new when I swap them out.

I have been purchasing my filters from them and they have always been of the best quality. they are very cost effective buying in bulk. And i get reminded when to order again so I never run out. That a great program.

We were VERY disappointed in
on September 24, 2026
Posted by: Customer
We were VERY disappointed in the lack of service. We gave the correct dimensions, you sent the filter with the correct dimensions printed on the filter, but the filter does NOT fit, it’s too big!!!!
When we called about the problem you indicated you wouldn’t help us to straighten the problem out and that’s the way it was left. Now we are out of 50 + dollars!!
We are senior citizens who live on a very fixed income
I will NEVER recommend anyone to your company ever again!!!!!!!
