12.75x21x1 (Actual Size) Accumulair Diamond 1-Inch Filter (MERV 13) (4 Pack)
These seem to work pretty good !! I change my filters out 4 times a year, every season.., and you can always see the stuff it has taken out of the air
I use these at home and they do the job. When I change them out you see all the gunk and residue left behind
I like this! You can actually see the change when you switch it out. I would recommend, it really works!
