What was advertised as 24"
on September 18, 2025

What was advertised as 24" length is actually 23 1/4" so I have to shim the filter for it to not rattle when the air turns on. I have air intake on the ceiling.

It is hard to find

It is hard to find the exact size filter in my area. Until Filterbuy, I always had to buy a Filter and cut it to fit. Thank You for having my "exact" size in stock, with many quantity options!
