Does higher MERV rating restrict airflow?

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 is a good MERV rating for air filters?

about 5 to 8
Using an air filter with a MERV rating of about 5 to 8 is appropriate for most residential homes. MERV 5 – MERV 8 filters provide good filtration and will remove most pollen, mold spores, and dust mites.

What MERV 17?

A HEPA filter at a MERV 17 rating will trap 99.97% of air particles that are 0.3-1.0 microns in size. The filter is able to trap 99% of air particles 3 to 10 microns in size. This is much better than a MERV 13, and this is the efficiency of the lowest-rated HEPA.

Is MERV 11 too restrictive?

Can my furnace handle a MERV 13 filter?

The ideal MERV filters for both air filtering and furnace efficiency are 7-13, experts say. These filters can be used without any modifications to your equipment. Your system may handle MERV 14-16 with no discernable stress. However, many residential systems require modifications to pull air through these filters.
