Highly recommend! Great service and affordable

I was able to buy this online and receive it in a few days. This filter is not sold in any of the big box stores, so I was pleasantly surprised. I did not realize my husband ordered the same filter through our AC repairman. He dropped it off and charged us more than twice what we paid through Filterbuy. I highly recommend them!
