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.

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.

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.

Initial request on order asked for any… Initial request on order asked for any further contact on sales, prices or sizes be sent to receiver of first order. They are still coming to me who has no need of them to the address they where sent to,which does. Please do so as requested. Thanks Other then that, EXCELLENT SERVICE!

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.
