FilerBuy A/C filters; excellent result… The FilerBuy A/C filters did an excellent job over the past year in trapping the particles in our air. We change the filters every 3 months throughout the year in our Florida home and we will be ordering this next year's supply today.

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.

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!

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.
