What Does MERV Mean?

MERV stands for Minimum Efficiency Reporting Value. MERV Ratings are a rating system designed by ASHRAE to report the effectiveness of air filters.

What MERV Rating Filter Do I Need?

The higher the MERV value, the greater the percentage of particles captured within the air filter.

MERV Rating Categories

MERV Ratings 1 to 16 are considered HVAC system grade filters suitable for residential HVAC systems. Anything above 13 is considered HEPA.

MERV Rating 17 - 20

MERV 17 to 20 filters are used explicitly in industrial or scientific applications such as surgical theaters and other applications that require absolute cleanliness.

How to Choose the Right Filter

Check the MERV rating, as not all filters are created equal then check the dimensions. Check your furnace as it might not accept a higher MERV rating.
