Furnace Filter

These filters seem to do the job. House ducts are clean which to me means the filters work.

A cost effective way to replace your furnace filter monthly reducing blower workload and maximizing air filtration. You basically can't go wrong.

The filters you sent are

The filters you sent are clearly lower quality than the ones I typically use. Thin, fewer heavy duty folds etc. Really cheap product and I was hopeful you could be my ongoing supplier rather than a one time fix. Too bad!

Filters dont fit snuggly
on October 15, 2025
Posted by: Anonymous
The filters are off size a little so they dont fit snuggly. They fall and lay on the grate and get sucked back up when air comes on. I have 9 left. I request a replacement order. I can send the others back at your expense for your review. I am afraid to reorder again. Dont want the same problem twice
