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.

A new customer What's with all the horrible reviews? I ordered oddly sized air filters and that's what I received. Looking at the reviews I figured my filters would never ship but nope. I got mine in 2 days and they fit perfectly. The fast shipping time was great because im dealing with the texas heat right now. Will buy more soon.

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.

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!

Not even close to size. The filters were supposed to be Merv 13 20x25x4. The actual size is 19-7/16 x 24-7/16 x 3-11/16. Needless to say they did not fit my filterbox and air can freely flow around the filter. Compared them to the Honeywell filter that came with my furnace and that one was sized as labeled. Who knows what the actual Merv rating is on that filter if they "cheat" on the size. Edit: After contacting Filterbuy, they have offered a full refund.
