Here is the full MERV rating chart: The most prevalent MERV ratings are MERV 4, 6, 8, 10, 12, 14, and 16: A Higher MERV rating automatically means a better filter. You can see from the MERV scale above that MERV 10 filter will filter out 85% of 3.0-10.0 μm particles. MERV 12 filter, for comparison, will filter out 90% of the same particles.

Oct 7, 2024 · Which MERV-rated air filter should you be using? Here we list and explain everything you need to know about MERV ratings, ranging from 1-20.

Oct 19, 2024 · MERV 5 – MERV 8 filters provide good filtration and will remove most pollen, mold spores, and dust mites. Using MERV 5-8 filters will keep your HVAC system more efficient than using higher-rated filters, as long as you replace your filters regularly.

Jun 6, 2024 · A MERV 5 filter will trap up to 34%, MERV 6 will stop 35-49%, MERV 7 will prevent up to 69%, and MERV 8 will catch up to 85% of particles. These filters are slightly more restrictive than the MERV 1-4 filters and have the ability to catch mold spores and some pet dander along with dust and pollen.

Feb 24, 2025 · Minimum Efficiency Reporting Values, or MERVs, report a filter's ability to capture larger particles between 0.3 and 10 microns (µm). The rating is derived from a test method developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) [see www.ashrae.org].

Apr 29, 2022 · This chart is an overview of MERV Ratings and what pollutants each tier removes. The higher the MERV for each set, like MERV 8-10, the more of the pollutant will be removed. A MERV 8 filter removes about 70% of pollen while a MERV 10 removes 85% of pollen.

Aug 13, 2022 · What is MERV 8? If you are looking for something that does more than just improve air quality, MERV 8 filters do that job. These are about 20 times more efficient than regular glass fiber filters and with a dust spot efficiency of 30-35%. They are also more efficient than a MERV 6 filter.

The MERV rating is determined by the size of the particles that the air filter can remove, with the smallest particles being the most efficient at removing. The MERV rating is a scale from 1 to 16, with the higher numbers being the most efficient at removing particles.

Choose a MERV rating that matches your needs: Residential use typically requires MERV 6-8. Hospitals and sensitive industrial applications might opt for MERV 13 or higher.

Aug 12, 2021 · merv 5-8 Filters with MERV ratings between 5 and 8 are often considered medium-quality, which is sufficient for most homes. However, they need to be replaced more frequently than high-quality filters.
