I think they’re great

I love that these come to the house. They are good quality. I have four cats in my house. Not sure if the furnace filter has anything to do with it or not, but there’s a lot of hair in the filters when they are changed and not so much laying around in my house.

Good value, convenient...avoids having to search - and hope they have them - at a large store.
