    I have placed several furnace filter orders from and have never been disappointed. From the order placement to the fulfillment to the delivery, I have only had positive experiences. The quality and performance of the filters I received (20 x 25 x 1 MERV 13 2200) have exceeded expectations.

    Thick and Filtery

    Posted by Unknown on Jan 3rd 2018

    Just installed the first filter, and have to say it’s already made a difference. Kids had been sneezing and coughing with previous brand Filters. But not with these: they can breath easier now and I will use each one for about 2 months each.
