I have not used one yet. They look just as good or even better than the ones I can buy in the store. The size 20x22x1 is hard to find. So glad I found a company that has this size. Thank You

So far they seem to be working fine, but I only installed them a month ago so still to early to tell.

Easy to install and since we have cats, do a great job plus they still look pretty good even after three months.

This is a little early to look for a review. They just arrived and were installed. The only valid review right now was that they fit.

I always get first class service from Filter Buy. My most recent purchase I ordered Monday afternoon and was shocked to find them on my porch the next day. The filter quality is top shelf. I highly recommend them.
