Review on FilterBuy 20X20X1 Pleated Furnace Filters by James Crofton

They work. During this time the whole house got sick and I found myself changing the filter every 10 days or so. Given that the house was dusty and dirty I figured it was my fault and bought another set believing that now that we are in better condition the filters will last longer. God how wrong I was. I bought and received filters, not 10 pieces. Days ago. I immediately put a new one in as the old one was choking my oven. The filter lasted 3 days. I just installed another one a few days ago and today my oven went into panic mode because it just couldn't get air through that filter. I've had 3M filters of this grade and even when they were dead dirty my oven was at least able to let some air through. These filters have no discoloration and look brand new when removed. I will definitely not buy these again.
