Will MERV 11 filter hurt my furnace?
A MERV 11 air filter has a higher efficiency rating. In particular, using an air filter with a MERV rating that’s too high can damage the compressor, heat exchanger, and air conditioner coil. In most cases, a MERV 11 air filter isn’t too high for residential use.
Will MERV 12 hurt my furnace?
The short answer is this: The best MERV rating for your heating and air conditioning equipment is the MERV recommended by the manufacturer. It’s usually in the range of 8-12 MERV. When in doubt, choose a MERV 8 to MERV 10 filter rated for high airflow, so it won’t damage your furnace or air handler.
What MERV filter can my furnace handle?
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.
Is there a downside to high MERV filters?
Wrong. 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. If the MERV rating on your furnace is too high, it may force your furnace to work too hard and leave it vulnerable to damages.
Is MERV 8 good enough for Covid?
Filters with MERV-13 or higher ratings can trap smaller particles, including viruses. Many home HVAC systems will have a MERV-8 filter installed as the default. By itself, using an upgraded HVAC filter is not enough to protect people from COVID-19.
What MERV rating is best for home use?
between 8-10
In general, the best MERV rating for a home is somewhere between 8-10. These filters will capture a large portion of the airborne particles and improve indoor air quality without making your energy costs rise significantly.
Is MERV 13 too restrictive?
At this point, it’s also important to note: MERV ratings go above 13. However, they’re too restrictive for normal home HVAC systems, and thus using them can cause potentially expensive problems.
What MERV rating does YORK recommend?
8-15
York furnace filters are good at trapping a variety of particles, including smoke, mold, dust, pollen, viruses, and more. Our premium aftermarket York replacement furnace filters are available in Minimum Efficiency Reporting Value (MERV) 8-15.
Is MERV 13 too high for home?
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.
Will a HEPA filter stop COVID-19?
When used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from COVID-19.
What MERV rating is HEPA?
MERV 17
A HEPA is the creme de la creme of air filters with an equivalent rating of a MERV 17 or higher. 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.
Is FPR and MERV the same?
MERV ratings extend from 1 to 16. MPR measures ratings based on sizes 0.3 to 1 microns. FPR ratings are on a scale from 4 through 10. The MERV filter rating is the domestic and international industry standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers.
