Avoid at all costs They sell filters that say they are a certain size (20x20x4) for example but they send filters that are 19.25x19.25x3.25. When I complained, they said to read the fine print on their website.

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!

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 Customer Service I ordered 12x12 filters and when I received them, they had shipped 10x10 by mistake. I called and they to care of the mistake quickly. I received the correct filter the next day. Great customer service. Thank you for the quick response. Highly recommend Filter buy.

Bought 20x20x4 filters. They're not even close to that size. Bought 20x20x4 filters. These are a standard size available at any hardware store. Typically 19 5/8 x19 5/8. Filterbuys were 19 3/8 x 19 3/8 and weren't same thickness either. (smaller all around) So needless to say, they don't fit. Not sure how they can list it at 20" when it's much closer to 19". Very misleading on their website. Had to pay for return myself.
