1.	What is an MPR rating on air filters?(a) Magnitude performance rating(b) Micro-particle performance rating(c) Macro-particle performance rating(d) Moles per rateThe question was asked in semester exam.This is a very interesting question from Sterilisation topic in division Reactor Engineering of Bioprocess Engineering
Answer» RIGHT choice is (b) Micro-particle performance RATING To explain: MPR (Micro-Particle Performance Rating) MPR Rating is a rating SYSTEM developed by 3M. It rates the manufacturer’s filters and their ABILITY to capture AIRBORNE particles smaller than 1 micron.
