So far, all is okay but they have been installed for only one week at this time. I would appreciate seeing the MRV number printed on the filters themselves, but so far have noted it only on the shipping container. How am I to truly know that they are MERV 13? Can you respond to this question?

They're used in in the garage and they collect a lot of dirt. I changed them often
