For glass fiber HEPA media, MPPS typically falls in the 0.1–0.3 micron range depending on fiber diameter and media structure. EN 1822 rates filters at MPPS because it represents the worst-case filtration scenario: if a filter meets its rated efficiency at MPPS, it will exceed that efficiency at all other particle sizes. MPPS efficiency is therefore a more rigorous and meaningful metric than fixed-particle-size efficiency alone.
