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 8 corresponds to Filtrete MPR 600 and MPR 1000 (marketed as its Dust and Pollen / Clean Living tiers) and to Home Depot FPR 5.
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.
