Merv 11 home air filters 20x25x5
Your review: Exactly like the one installed in my old electronic filter slot when I got a new furnace/AC unit; got these for the other unit. Perfect fit, slid right in.
Pros: Perfect conversion
Cons: Took longer than usual to get product, but I was in no rush. Had never dealt with this company before, but they came through with flying colors! Would buy again
