All About MERV Ratings (Infographic)
MERV Ratings were first created in 1987 by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) as a scale to rate the effectiveness of air filters. MERV ratings serve as a standard that allows buyers to understand the efficiency of their filter. MERV ratings run from 1-16, with 8-13 being the most common household filters. Before you can choose which MERV rating is best for your home, it’s important to understand what MERV ratings really mean.
