If you’re worried about the effects of breathing in fine air particles, that’s another reason to choose a MERV 11 air filter over a MERV 8 air filter. Fine air particles are 2.5 microns and smaller. MERV 11 air filters can filter out a large percentage of fine particles, but a MERV 8 air filter can’t.
Is MERV 11 a good rating?
MERV 11 rated air filters have a filtration efficiency of a little over 90%, making them highly efficient. MERV 11 furnace filters effectively trap pollen, dust, lint, dust mites, and mold, along with smoke, pet dander, smog, auto emissions, bacteria, and other such fine particles.
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.
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.
Is MERV 8 good enough?
A MERV 8 air filter is efficient at trapping a majority of indoor particulates that could debilitate those with asthma and allergies, or even cause long-term respiratory problems.
Can my furnace handle MERV 11?
The short answer is that it can, but it’s not really an issue except under extreme circumstances. Most modern HVAC systems have no problem working with higher MERV filters, which is why millions of homeowners depend on them.
Can I use a MERV 11 filter on my furnace?
The MERV 11 rating is one of the most popular choices when it comes to residential use. A MERV 11 rated furnace filter can trap the majority of harmful contaminants that are present in the air. This includes pollen, dust, lint, mold, dust mites, smoke, pet dander, and smog.
Does MERV 8 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.Learn how to maintain your. home and HVAC this fall. MERV Minimum Particle Size 5–8 10.0–3.0 μm 9–12 3.0–1.0 μm 13–16 1.0–0.3 μm 17–20 < 0.3 μm.
How often should MERV 8 filters be changed?
The basic recommendation for furnace filters replacement is every 3-4 months for MERV 8, every 6 months MERV 10 and 11 and every year for MERV 16. There are other several factors to consider when determining when to change your home air filter.
What does MERV 11 mean?
The MERV 11 will increase indoor air quality by removing 85% of micron sized contaminants in the air which maintains the efficiency of the HVAC unit. It is also highly recommended if there are pets in the home which can greatly reduce the air quality indoors.
Does air filtration help with Covid?
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 level is HEPA?
All HEPA filters have a rating of a MERV 17 or higher. A HEPA filter with a MERV 17 rating will trap 99.97% of air particles that are 0.3-1.0 micron in size and an even better % of particles below 0.3 microns and above (HEPA filters are rated at their worst performance).
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.
Are MERV 8 filters washable?
Washable and reusable MERV 8. 99.99% inactivation of SARSCoV-2 (COVID 19) viral particles. Proven post wash MERV 8 ratings.
Is MERV 11 better than 12?
The difference between 11 and 12, therefore, is quite negligible. We do not carry MERV 12; MERV 11 does just as good a job. MERV 12 filters trap 80 to 89 percent of average particles of 1.0 to 3.0 microns, with an average particle size efficiency of 90 percent or better. As you can see, they’re pretty close.
Does MERV 8 filter wildfire smoke?
While MERV 8 filters are probably ok most of the year, they aren’t rated for removing the fine particulate in wildfire smoke. Last wildfire season, buildings recirculating air through a MERV 8 filter were in better shape than those with less filtration, but they struggled during Missoula’s worst smoke days.
Is MERV 11 good for allergies?
Our MERV 11 furnace filters are great for anyone with allergies. Not only do they filter out more contaminants than the MERV 8 filter, but they are an affordable option.
What MERV filter is best?
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.
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.
Which is better MERV 10 or MERV 11?
MERV rating 9-12 A MERV 9 will trap less than 50% of particles sized 1.0-3.0 microns, MERV 10 will stop up to 64%, MERV 11 will get up to 79%, and MERV 12 is capable of catching up to 89%.
Does MERV 11 filter smoke?
A MERV 11 filter traps all that stuff plus pet dander, smoke, smog, and airbornes from coughs and sneezes. A MERV 11 is a must if you have kids or pets. It will filter out a lot of the most common air pollutants and irritants.
