Never again Ordered and when they arrived they did not fit. Was given the same song and dance another reviewer was, that it is my fault that I did not measure and that not making the filters to the correct size “is industry standard” Be warned 1) Any returns require YOU THE CUSTOMER to pay shipping 2)They record all calls but never inform you of that 3)They are unable to take responsibility or blame for even the smallest thing they do wrong NEVER BUY FROM THEM! Pictures of cute puppies do not cover for fraud

A trusted brand A trusted brand, especially during a pandemic! Made right here in 🇺🇸. I love that I can order online and click and reorder, right through my email reminder! Very satisfied customer😍 Thank you!!!

Smaller Than Standard 20x20x4 Filter Size The positive: good price and fast shipping. The negative: Their 20x20x4 Filters are much smaller than 20x20x4 filters made by the name brands. As a result, they don't fit properly in my air handler. Rather than pay to send them back, I am going to glue a cardboard frame to them to make them fit properly. In addition, the manufacturing quality of the filters are suspect. Name brands have spacers that keep the pleats evenly spaced. These Filterbuy filter pleats are not evenly spaced and the pleats are bunched up near the edges. They are also glued into place and cannot be adjusted. Save yourself the hassle and get name brand filters or be sure to verify that the ACTUAL size of the filter will fit your application.

Great service I recently ordered two filters and when they arrived they were damaged. I contacted the company with pictures of the damage and they told me they would send replacements and three days later I got two replacements in perfect condition. Cannot recommend this company highly enough. Service over and beyond. Bill

Low price filters here are better than… Low price filters here are better than comparable filters from big box stores. Before filterbuy, my filters were bowing inward. The cardboard frame is very sturdy keeping my filters straight after a month. Which leads me to the subscription, it's a good and easy reminder to change. I'm an HVAC technician, I'm happy with this service and I recommend them all the time.
