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.

Excellent Customer Service Response First time ever, I received the wrong order. Size sent was 17"x25"x1". Mine were supposed to be 20"x21.5"x1". I called them and they apologized and said that they would immediately send out the replacements. So the rating is the middle ground. 5 stars on the customer service and 1 star for the original order. Great Company to work with and excellent products. Update: The replacement filters arrived four days later.

Amazing customer experience Amazing customer experience. They shipped our product and it arrived in a very timely fashion. We realized that we had ordered the wrong product - we called them, and their return process was so simple. Exceptionally good company to work with!

Ordered custom filters (15.5 x 29.5 x… EDIT 2/1/22 Filterbuy reached out because of my review - and shipped a new replacement set free of charge. They mentioned they would do this without review - so my bad, I should have reached out. New filters are great and arrived fine. Raising to 5 stars from original 3! Original review: Ordered custom filters (15.5 x 29.5 x 2) from them. Fast shipping, got in 4-5 days for reasonable cost. Filters fit just perfect with the custom fit. However, the filters are seemingly of very poor quality, and were heavily damaged during shipping. The sides of the filter easily detach from the cardboard (weak glue.) Removing two stars for cheap construction and not providing enough box protection to prevent UPS/Fedex from destroying.
