I have been using FilterBuy filters for five years. The filters work great, doing exactly what they are designed to do.

Only been on a week. Recieved them in a timely fashion. Look like the filters will work out fine.

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.
