9-12 MERV – These filters are more efficient and usually offer the best indoor air quality improvement for residential applications. Deep pleated filters fall into this category. Because they work so well at removing airborne pollutants, they must be regularly checked to ensure proper airflow.
Is MERV 11 too restrictive?
A MERV 11 air filter has a higher efficiency rating. Meaning, it can capture finer particles and clear more contaminants out of the air. … In most cases, a MERV 11 air filter isn’t too high for residential use.
What MERV rating should I get for home?
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.
Is MERV 8 good enough?
MERV 5–8 (good): These filters are better at catching small particles (3–10 microns) like mold spores, hair spray, dust mites and animal dander. MERV 9–12 (better): The best option for residential use.
What is filtrete MPR rating?
*Your filter’s MPR (Microparticle Performance Rating) indicates its ability to capture tiny particles between 0.3 and 1 micron in size. The higher the MPR, the more microparticles—such as pollen, pet dander, smoke, bacteria and viruses—your filter will capture from the air passing through it.
Is MERV 13 too restrictive?
“MERV” is the standard rating system used in the HVAC industry to determine how well a filter works. … And MERV 13 is the highest rating recommended for home use. (Anything above it will restrict airflow too much and could damage your HVAC system).
Can I use MERV 13 in my house?
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. Many home HVAC systems will have a MERV-8 filter installed as the default. … Be sure the HVAC filter is correctly in place.
Is MERV 11 better than 12?
Luckily, MERV 11-rated filters handle those particles — such as pet hair and dust mites — with ease. Likewise, MERV 12 filters catch about the same types of particles. The difference between 11 and 12, therefore, is quite negligible. We do not carry MERV 12; MERV 11 does just as good a job.
What MERV is too high?
High MERV filters, specifically MERV 12 to MERV 16 filters, stop more and smaller particles of pollutants, allergens and other junk that leads to bad indoor air quality (IAQ). That’s a fact.
Is MERV 11 better than 13?
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.
Can you wash Filtrete filters?
How do I clean my pre-filters? First, turn off your Filtrete™ Smart Air Purifier. Next, pull the two pre-filters out and rinse them off in your sink. Simply run them under tap water to remove any dust and debris.
What does MERV 12 filter out?
MERV rating 9-12
This range of MERV values can begin trapping particles in the 1.0-3.0 micron range. In this range, we start to see pet dander, lung-damaging dust, and auto-emissions trapped. Filters in this range can trap more than 85% of the particles sized 3.0-10.0 microns.
What MERV rating is best for allergies?
MERV ratings of 9-11 mean at least 90% particulate resistance. If you suffer from extreme allergies, you’ll want to look for a filter with at least a MERV rating of nine. These filters capture particles as small as one micron. MERV ratings of 12-16 are reserved for rooms that need absolute cleanliness.
Is MERV 16 too restrictive?
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.
What is a HEPA filter MERV rating?
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 7 good enough?
For most residential systems, experts suggest using an air filter with a MERV value between 7 and 12. These filters offer adequate filtration and remove common contaminants such as pollen, mold spores, dust, pet dander, and tobacco smoke.
What MERV rating can my HVAC 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.
Does MERV 13 filter smoke?
The minimum MERV rating for removing fine particulate in smoke is MERV 13. You don’t reach HEPA levels of particulate removal until MERV 17. However, a MERV 13 filter is effective at removing the fine particulate in smoke when air recirculates through the filter.
