Web26 mei 2024 · The MPR system, like the other two, uses a numerical scale on which higher numbers indicate better filtration. The MPR scale, however, uses much larger numbers. Their basic filter is rated at 100 and their most efficient filter is rated at 2800. The MPR-2800 would qualify as a MERV-14, so even though 3M emphasizes the smallest size … WebThe table is based on the new ISO norm which is actually defining, for each filter, an efficiency on particles of 1 micron, 2.5 microns and 10 microns. To be noted however that those filters are also often able to filter smaller particles to a certain extent. nwsports photo
