Prefect fit!
on June 22, 2025
Posted by: Leah C.
Ive had lots of trouble finding a filter that actually fits in my unit. While they all list the same general dimensions, they are not all the same. This one slid right in! I will be back in a few years to buy more from you!

NOT the size as advertised!

Very disappointed in this purchase. The filters are advertised as 20x20x4 but are NOT that size, they are 19. 3x19. 3x3. 25. These don't fit at all, entirely too small. Will not order again.

Too small

In large print the ad said 16x25x4, I am sure in tiny font it said the actual size, which was 1/2 smaller in 3 dimensions than what fits welll in my HVAC . Had to add tape so it wouldnt fall through.

Tighter fit compared to same

Tighter fit compared to same unit I purchased last year. Struggled to install. Had to force it into place. Seemed slightly wider than previous filter.
