These filters are great. We have a hard to find size. We have been ordering these filters for several years. They work super!

I did not sign up for or want reoccurring purchases. Will decide when I need more filters.

It makes noise

My last pleated filters didnt make any noise. This one makes a bit of a whistling noise when the air handlers running. Not enough to be annoying, but I wonder if its indicative of a longer term problem?

Sizing not the same as other filters
on August 31, 2025
Posted by: Shelby O.
The filters are a great price however they were not the same size as my current filters. I was able to get the filter in my furnace but it was pretty tough. Worried about getting it back out!
