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!

Customer service A+ Could not be happier with them. I originally made an order, I messed up the order, I waited five months to please exchange my order and Not only did they send me the correct filters, they told me to keep the ones that were wrong. Customer service A+

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.

Good experience all around 1 - Ordering and fulfillment - excellent. Product went out same day and was delivered next day (I'm just one state away). 2 - Customer service - excellent. Fedex mis-delivered to some place I still don't know where - nothing recognizable in Fedex's photo. Constance researched while I was on the phone, shipped out again within an hour or two, and replacement shipment arrived next day. (This Fedex driver must have had a GPS.) 3 - Size of product. I read the complaints before I ordered. The complaints don't seem valid. First, the actual size is plainly stated. Second, before I ordered I measured one of the 12x12x1 filters I already had (different brand) and IT TOO was 11.75x11.75x0.75, so this seems to be a standard. Maybe not the universal standard, but filters fit the duct opening just fine.

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.
