20x20x1 Filters

I bought these but they run a little small & sometimes I look in & they have slipped out! All my other 20x20x1 fit perfectly! Will probably have to add some duct tape to make them fit correctly! Was a bit disappointed!

Filters are expensive, but Im grateful this company exists for landlords, business owners or just residential homes. It saves so much time and the price is something you cant beat.

Bad filter sizing
on August 26, 2025
Posted by: Anonymous
I purchased (6) six 18x24x1 merv 8 filters for my daughters house. Upon installing one of the filters I almost lost it in opening for the filter. Upon inspection and measuring the filters, I found the filter were 1/4 tonarrow and 1/4 to short. The filters are barely held in place by the return air register. I am not pleased sizing of the filters.
