Is MERV 13 a good filter?
A MERV 13 filter is a step in the right direction and captures more particles than a typical MERV 8 filter. However, it is not as good at capturing small virus sized particles like a HEPA can. A MERV 13 will trap less than 75% of air particles that are 0.3-1.0 micron in size (the coronavirus is 0.1 microns).
Can my furnace handle a MERV 13 filter?
MERV 13 is the highest MERV value safe for residential furnaces; the higher ratings are used primarily in commercial units. If you are wondering what MERV to try, keep these recommendations in mind; ASHRAE recommends MERV 6 or higher. US Department of Energy recommends MERV 13.
What is better than a MERV 13 filter?
If you are looking for a filter that can capture small particles, then HEPA is a better option. MERV 13 filters are the most popular type of air filter, and they are designed to remove particles from the air that are larger than 0.30 microns.
