Amazing customer experience Amazing customer experience. They shipped our product and it arrived in a very timely fashion. We realized that we had ordered the wrong product - we called them, and their return process was so simple. Exceptionally good company to work with!

Avoid at all costs They sell filters that say they are a certain size (20x20x4) for example but they send filters that are 19.25x19.25x3.25. When I complained, they said to read the fine print on their website.

Customer service A+ Could not be happier with them. I originally made an order, I messed up the order, I waited five months to please exchange my order and Not only did they send me the correct filters, they told me to keep the ones that were wrong. Customer service A+

Not even close to size. The filters were supposed to be Merv 13 20x25x4. The actual size is 19-7/16 x 24-7/16 x 3-11/16. Needless to say they did not fit my filterbox and air can freely flow around the filter. Compared them to the Honeywell filter that came with my furnace and that one was sized as labeled. Who knows what the actual Merv rating is on that filter if they "cheat" on the size. Edit: After contacting Filterbuy, they have offered a full refund.

A new customer What's with all the horrible reviews? I ordered oddly sized air filters and that's what I received. Looking at the reviews I figured my filters would never ship but nope. I got mine in 2 days and they fit perfectly. The fast shipping time was great because im dealing with the texas heat right now. Will buy more soon.
