Haven't actually used the filters yet. But the cardboard edging comes apart. Had to tape together.

I purchased 6 - 16 x 20 x2 Mervin 8 filters. We dont have issues or pets. They are as good quality as any filter Ive purchased over the years, just less expensive. So, far very content!

20x20x1 Filters
on August 26, 2025

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!
