As a first time filter buyer I was a little skeptical. I ordered a custom size and received something else. But to my surprise it fit perfectly! Plus it works great! I will definitely be reordering!

Manufacturing off by 1/8+ inch
on July 25, 2025
Posted by: Anonymous
Manufacturing - the 24" side of the filter measures 24 1/8 inches due to the frame note being attached evenly along the edge. The specifications on the website showed the filter size as 23 7/8 inches, which would have fit perfectly. Now, I have to bend / crinkle the filter to fit it into the opening.
