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!

Absolutely great customer service Absolutely great customer service. I purchased six MERV13 filters before learning that the filter could damage my HVAC because the motor wasn't strong enough to handle them. Four months later I called FilterBuy on the off chance that I could return them for credit. The customer service rep was was not only friendly, she gave me a total refund. I offered to return them at my expense, and she told me to donate them, which I did.

The customer service was great The customer service was great. I needed a filter that was no longer listed by size. Other attempts to locate the filer met with negative results. Upon contacting filterbuy, their customer service took the time to assist me in getting the filter I needed.

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.

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.
