Microparticle Performance Rating (MPR)
Micro-Particle Performance Rating is a metric developed by 3M Filtrete indicating how effectively a filter can capture particles between 0.3 and 1 micron in size. MPR is a metric indicating good, better and best, with filters containing the highest MPR (1900 or greater) being the most effective at filtering airborne particles.
