Great price for this four pack of a somewhat uncommon size..

Have only used one of these. My first time buy but happy with it

If you have pets get this filter

These filters are well made and effective

Installed 2 of them ... worked well. Had a good "feel" to them.

Best quality around and excellent price

been using for years buy when they our on sale

Did not fit properly was off by a few mm it’s the same size as the one currently in the vent however not sure if it was not cut properly when manufactured but had to squish it in place

Strong material.

I like the 4 pack
