I specially ordered MERV 14 filters to protect my operation with a higher degree of filtration. This box of 6 filters arrived unlabeled. There is no indication of what MERV rating I received. I feel ripped off. They look slightly better than the FPR 7 (MERV 11) I used. But I have no idea what it is. Should I assume I have MERV14 and have good protection? No! The whole point of rating filters is that you KNOW what they are. Sending unmarked filters with no paperwork is unforgivable!
