Not satisfied!
on May 2, 2026

These filters do not fit! They are the wrong size! They are 1/2" too short all around and do not filter anything! They just rattle around and let the dust and dog hair pass right through! They are 15 1/2" by 19 1/2" by 3 1/2". The quality is poor and they are not anything like the the filters I bought before.

I didn’t think the actual size would be an issue but it was especially the width

The filter is not thick enough for the slot I put it in my attack ac unit like the Honeywell one was.

It was the way my ac is made but I could not use it because it didn't fit.
