MERV 9-12 Filters: The U.S. Environmental Protection Agency advises that filters with MERV ratings of 9 to 12 are almost as effective as true high-efficiency particulate absorption, or HEPA, filters when it comes to removing particles from indoor air that are hazardous to your health, which makes them ideal for homes …
Is MERV 9 good enough?
MERV rating 9-12
Filters in this range can trap more than 85% of the particles sized 3.0-10.0 microns. A MERV 9 will trap less than 50% of particles sized 1.0-3.0 microns, MERV 10 will stop up to 64%, MERV 11 will get up to 79%, and MERV 12 is capable of catching up to 89%.
Is MERV 9 too high?
While the highest MERV ratings are the most effective for air quality, they can harm your HVAC system. A higher MERV rating means a higher resistance, which means less airflow.

What MERV rating can my HVAC handle?
The EPA recommends MERV ratings of 9-12 because it is the most effective at keeping your home’s air clean. A filter with this rating will prevent particulates as small as 1 micron from entering your HVAC system. This rating qualifies as HEPA (high-efficiency particulate absorption) level.
What is MERV number?
MERV stands for Minimum Efficiency Reporting Value. MERV ratings are on a scale of one to 20 depending on the minimum size of the particles a filter can be expected to capture: … A filter with a MERV rating of nine to 12 captures particles greater than one micrometer. This includes most dust and common pollutants.
