What is the highest rated MERV filter?
Well, MERV ratings range from 1 to 20, with 1 being the lowest level of filtration, and 20 being the highest. Filters that are MERV 16 through 20 are usually only found in hospitals, cleanrooms, and nuclear power plants.
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.
Are higher rated air filters better?
High-rated air filters use more energy than lower-rated varieties. More pleats means more surface area to capture dust, dirt, and allergens.
What MERV rating does Lennox recommend?
We advise buying no less than a MERV 13 if the system allows for it.
What MERV rating is filtrete 1500?
MERV 12 rating
Each Filtrete Healthy Living 1500 filter has a microparticle performance rating (MPR) of 1550, which is comparable to a MERV 12 rating. This is one of the highest residential MERV ratings, which were created by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
What MERV rating is HEPA?
MERV 17 to 20
High-Efficiency Particulate Air (HEPA) filters are not MERV-rated, but a HEPA filter is typically considered as MERV 17 to 20, which is the highest group in MERV ratings.
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?
In most cases, a MERV 11 air filter isn’t too high for residential use. Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in a home without impacting airflow.
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.
Can my HVAC handle MERV 13 filter?
MERV 13 air filters are the highest-rated air filters for home use. Any air filter with a rating higher than 13 will restrict air flow to the point of which could cause damage to your HVAC system, resulting in an added expense to fix it.
