I couldn't find my oddly sized filters anywhere else. The price was very reasonable and were delivered within a week. I highly recommend this company and will certainly use them again in the future.

Timely service and the filter fits. The initial impression was that the quality of construction is not as well made as others I have bought directly. Time will tell how it holds up.

Excellent filters for a very good price. I've been using Filterbuy filters for over 10 years and I couldn't be happier with the overall performance. You can't go wrong buying Filterbuy.

I give you four stars. Can't say any more until I'm able to use them not due for change until December. Just wanted to stock up. Looks like they'll be a good fit and the framing looks strong.

Have not installed filter; it is a "backup." However, the process, price, etc. were fine.

rough fit

I had to cut down the filter in order for it to fit my unit. The actual size is different than what you send me. I make it work but not sure I will be ordering them from you again.
