I was pleased to find an American made source for filters that saves me money and delivers them right to my front door fast. The filters are as good or better quality than any I’ve used in the past. I highly recommend that you give Filterbuy a try.

Filter is fine. Nothing special but the price is hard to beat.

I feel like I immediately felt the air in my home cleaner. Our furnace has a built-in air purifier and my home was less dustier and it didn't have the usual after cooking smell that lingers for a day or so.
