My wife had had severe allergies, sinus congestion, and asthma for years. She has never breathed so well since we started using Filterbuy HVAC filters.

Best price.

These filters fit perfectly. I have 2 AC units. The units hold 2 20x20x1 filters. I change them every 5 to 6 months. The price is the best. I purchased 8 or 10 filters have enough for several years.

I thought it was cheaply made and fits very loosely. I won't be buying anything from you again

Good response to a shipping problem

I feel OCD to mention it, but I found it disturbing that my side by side 2 in filters had vertical pleats in one and horizontal pleats in the other. I doing see that it makes any difference though. I am hoping I will have nothing to think about when my subscription brings me two new Merv 11s in 3 months.

Finally

After many years of trying to find the right size and coming up long/short, I finally have the correct size for my 30+year AC intake plenum; and I didn't have to custom cut the size, myself.
