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.

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.

Excellent Customer Service Response First time ever, I received the wrong order. Size sent was 17"x25"x1". Mine were supposed to be 20"x21.5"x1". I called them and they apologized and said that they would immediately send out the replacements. So the rating is the middle ground. 5 stars on the customer service and 1 star for the original order. Great Company to work with and excellent products. Update: The replacement filters arrived four days later.

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.

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!
