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.

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.

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.

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!
