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.

Great service I recently ordered two filters and when they arrived they were damaged. I contacted the company with pictures of the damage and they told me they would send replacements and three days later I got two replacements in perfect condition. Cannot recommend this company highly enough. Service over and beyond. Bill

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.

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.

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!
