Just what I was looking

Just what I was looking for! Quality filters at a reasonable price, without having to order in bulk (I purchased 4 filters) and, in the size I needed (21x21x1). Easy to order, prompt delivery. The improved air quality inside my home was detectable from day one. Needless to say, I am one happy customer.

This is my first order. Filters are well constructed, sturdy, and the size is perfect. Before I found FilterBuy, I tried the usual suppliers and was unable to find the size that I needed and the MERV rate that I wanted. In addition, ordering is easy, the price is great, and delivery is fast.
I am sure that I will keep ordering my AC filters from FilterBuy. Highly recommended. Adriana
