MERV is the ASHRAE 52.2 standard. Filtrete (3M) prints its own MPR number and Home Depot prints an FPR number, and the two only approximate MERV. MERV 13 corresponds to Filtrete MPR 1900, 2200 and 2800 (Healthy Living / Ultimate tiers); the same filter often ships as MPR 1900 at one retailer and MPR 2200 at another and to Home Depot FPR 10.
Match on MERV when you cross brands. The same physical filter can carry a different MPR sticker at different retailers, so the MPR alone is not a reliable identity.
