Great way to buy filters!

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.
The emails after the purchase though! My lord. Talk about being spammed!

Clean home

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.

Smaller than standard filter.

The filters that I’ve used for the last 10 years measure 23 7/8 square and fit snuggly into the return air receiver. Your filters measure 23 3/8 square and barely cover the edges of the receiver allowing blow by around the edges. I had to tape them in to keep this from occurring. Not pleased with the product at all for this reason. I don’t believe I’ll purchase anymore regardless of the filter quality which I don’t know yet. I changed them quarterly and my ducts are super clean after 10 years and I want to keep them that way. I liked the price, but I guess I found out that you get what you pay for. Disappointed!
