We needed to order a hard to find filter size and the folks at FilterBuy make it for us. The price is reasonable and the product's quality is excellent.

FilterBuy filters do an excellent job filtering the air from our air conditioning systems. The system sizes are not easy to find and FilterBuy makes it easy and convenient for us! The cost is also very reasonable!

My wife has bad allergies so we thought wed try these filters. Amazingly they worked great for her allergies. We are so impressed with the quality of the filters! We will only buy them from now on.

Unusable

The size is on the filter but not even close! I understand a little room for easy installation and imperfections. But this is crazy! The filters don't even reach the holding tabs. If you want a filter bypass at low fan speed these are for you..At high speed it gets sucked into place. I bought 4 for the year, now in the garbage, what a waste!
