MERV stands “minimum efficiency reporting value” and a filter receives a MERV rating as determined by the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE). 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).
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.
Is MERV 11 or 13 better?
A MERV 11 rated furnace filter can trap the majority of harmful contaminants that are present in the air. A MERV 13 filter is capable of filtering out all particle impurities like dust, lint, pollen, mold, dust mites, pet dander, smog, and smoke. On top of this, it can also trap bacteria and viruses.
Is MERV 13 too high?
Filters within a MERV rating of 17-20 are almost never necessary in a residential home. A MERV rating of 13-16 is considered hospital level air quality, so it is unlikely your home needs any more than that.
Do MERV 13 filters help with Covid?
Minimum Efficiency Reporting Values, or MERV, reports a filter’s ability to capture particles. Filters with MERV-13 or higher ratings can trap smaller particles, including viruses. By itself, using an upgraded HVAC filter is not enough to protect people from COVID-19.
Is MERV 13 safe for my furnace?
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.
Is a MERV 13 filter washable?
A: Yes. After using the mask in public, the mask should be cleaned or sterilized. If you need to wash the mask, remove the filter material and hand wash. Machine washing tends to crumple the nose wire which will cause it to eventually break.
How long do MERV 13 filters last?
For Merv 8, 11 and 13 filters, we recommend that you change your filter at least every 3 months, however changing your filter every 2 months provides better filtration which provides healthier and cleaner air in your home.
What does MERV 13 mean in air filters?
MERV stands “minimum efficiency reporting value” and a filter receives a MERV rating as determined by the American Society of Heating, Refrigeration, and Air-Conditioning Engineers (ASHRAE). 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).
Is Aerostar a good filter?
Aerostar MERV 13 Pleated Furnace Filters It’s suitable for people with allergies, and especially for the ones suffering from asthma. The efficiency of this product is mainly because of the high MERV rating and its sturdy construction.
Can my HVAC handle MERV 11?
In most cases, a MERV 11 air filter isn’t too high for residential use. Meanwhile, air filters with a MERV 14 rating or higher are designed for commercial HVAC systems that can handle the thicker filter material.
What is the difference between MERV 13 and MERV 16?
MERV 13-16 filters are capable of trapping 90% or more of particles in the 1.0-10.0 micron range. MERV 13 will prevent less than 75% of the 0.3-1.0 micron particles from passing through, MERV 14 will get up to 84%, MERV 15 up to 94% and MERV 16 can trap 95% or more of the smallest particles.
What MERV rating does Rheem recommend?
What MERV rating does Rheem recommend? Rheem recommends filters of MERV 8 and above. This MERV level is strong enough to remove substances like pollen, dust mites, dust and pet dander from the air.
How many microns does MERV 13 filter?
MERV 13 filters are a step up from the MERV 8 or 9 rating. A MERV 13 filter can capture less than 75 percent of air particles that are 0.3 to 1.0 micron in size.
What are MERV filter ratings?
MERV ratings signify an air filter’s effectiveness at reducing airborne particles and contaminants. A filter’s rating is determined by the minimum size particle it’s capable of trapping (measured in microns). As filters become better at improving indoor air quality, their MERV rating increases, ranging from 1 to 20.
Do HEPA filters stop coronavirus?
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 is the difference between MERV 12 and 13?
MERV 10 – MERV 12 filters remove most 1.0 to 3.0 micron particles plus bigger ones. These include all those listed under MERV 8 filters plus pet dander, bacteria, most smoke/smog particles and most auto emission particles. MERV 13 – MERV 16 filters remove most . 3 – 1.0 micron particles plus bigger ones.
What MERV rating is best for home use?
As a general rule, residences do not use higher than MERV 8 filters. We do recommend that everyone uses filters that have at least an 8 MERV rating. These filters will remove the majority of pollutants from your indoor air.
What MERV rating should I use in my house?
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 washable furnace filters as good as disposable?
Disposable filters are more effective at trapping smaller particles. Washable are only good at protecting from large particles like dust. They do not filter out pet dander, bacteria, viruses or smoke, especially when they aren’t changed often enough.
