Too Short
on September 12, 2026
Posted by: Customer
Filters are too short. I purchased the 14x24x1 and they aren’t 24 inches in length, they are just barely 23. 5, I have pictures to prove it. Air ducts make sucking noise every time the air comes on. Drives us nuts. Will buy Filtrere air filter in the future because they fit.

Work great

These filters are great, change them once a month and they are a tad smaller that what I usually buy. They fit exactly right, with no bending.

Haven’t used yet but they look better than what I had bought so I returned them. I’m using the last of my good ones then I will be using your brand. I’m sure I will be satisfied

Fits good but it’s to early to tell how well it works.
