Understanding a MERV 8 Rating

Air filters are measured, evaluated, and rated using a variety of data. Understanding and comparing these figures is an important part of comparison-shopping for filters. One key element you want to look for in a high quality residential filter is a rating of about MERV 8 or higher.

MERV stands for minimum efficiency reporting value, and its scale is used to measure a filter’s poorest performance levels when filtering the smallest particles. The scale ranges from 1 to 16, with 1 being the worst performance and 16 being the best.

Choosing an electrostatic air filter with a MERV rating of 6 to 8 is a good way to separate the filters that aren’t worth your time from the rest. Although a 6 or 8 out of 16 doesn’t sound that great, remember that MERV ratings signify the worst-case performance of any given filter. With regular cleaning and care, you won’t have to worry about ever getting such poor performance out of your filter. Still, MERV figures can reveal much about the quality and sophistication of any given filter.
