What MERV rating is best for home use?
Why We Recommend MERV Rating of 8 or Higher Protects your HVAC system from dust clogs and corrosive particles.
Reduces dust in your home making for less housework.
Improving indoor air quality, especially when you are spending a lot of time at home, is important for your health..
Should I use MERV 8 or 11?
A MERV 11 filter would make their lives a lot more comfortable because it can pick up even smaller particles than a MERV 8 filter. If members of your family have those health concerns, we recommend a MERV 11 air filter—especially in the spring and summer seasons.
Is 3m Filtrete HEPA?
Designed for compatibility, this Filtrete™ Room Air Purifier Filter works with Honeywell™, Holmes® and Filtrete™ air purifiers and offers True HEPA Filtration to capture 99.97% of all airborne particles*. … Our top-of-the-line filter even captures ultrafine particles 1000x smaller than the human eye can see.
What MERV rating do I need?
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. The home air filters you’re looking for are rated anywhere between MERV 5 and 13.
What Merv level is HEPA?
Acronym for High-efficiency Particulate Air. A HEPA filter is ranked between 17-20 MERV; the highest group in MERV ratings. All HEPA filters are tested and certified to be at least 99.97% efficiency in removing particles as small as 0.3 microns.
Is filtrete a HEPA filter?
This Filtrete™ Room Air Purifier Filter features True HEPA Filtration, which pulls in and traps 99.97% of airborne particles from the air passing through the filter media**. Our top-of-the-line filter also helps capture exhaust particles, smoke, mold spores and pollen from the air you and your family breathe.
Is MERV 13 bad for HVAC?
Minimum Particle Size 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.
Should I use a MERV 13 filter?
13-16 MERV – Filters in this category are used in hospitals and clean rooms, where airborne contaminants must be almost completely eliminated. These are not recommended for residential use as they restrict airflow and can damage your heating and cooling system.

What is better than a HEPA filter?
Rated at removing 99.999% of airborne contaminants, ULPA filters are considered more efficient than HEPA filters. A HEPA filters efficiency rating is 99.995%.
Is MERV 13 the same as HEPA?
While a MERV 16 filter captures >95% of particles in the entire size range tested (0.3-10.0 microns), a HEPA filter captures 99.97% of particles with a size of 0.3 microns. The filtering efficiency is even higher for particles larger or smaller than 0.3 microns.
Do HEPA filters have MERV ratings?
HEPA Filters HEPA air filters are not MERV rated as they exceed the ASHRAE test protocol 52.2 used in determining the MERV ratings. In fact, HEPA air filters are the ONLY mechanical air filters that are tested and certified to meet a specific efficiency at a specific particle size.
Is MERV 15 a HEPA filter?
HEPA stands for High Efficiency Particulate Air filters and they are super-efficient. They will range from 17-20 MERV. HEPA filters meet standards that remove at least 99.97% of airborne particles down to the size of 0.3 microns.
Is MERV 13 too high?
One factor to consider is air flow through the system. … In some cases, using an air filter that is too restrictive for your system may cause low air flow problems as well. MERV 13 is the highest MERV value safe for residential furnaces; the higher ratings are used primarily in commercial units.
What happens if you wash a HEPA filter?
Washing the HEPA filters probably broke some of the fibers or made the gaps between the fibers larger. That would explain why more air passed through after washing, but also more particles! Washing bottom line: Washing HEPA filters with water significantly decreases performance you should not wash a HEPA filter.
What’s better than a HEPA filter?
Yes, ionic air filters can kill finer particles than the HEPA air purifier anywhere in the room. This is why it is suitable for larger spaces. The ionic air purifier is the choice for large rooms and commercial areas to keep dust at a controllable level.
Does MERV 11 restrict airflow?
A decade ago, it used to be that if you had an HVAC system that used panel filters rated 6 through 9 MERV, putting in a MERV 11 or higher filter would restrict airflow (known as filter pressure drop). … The thicker the filter, the more surface area per pleat.
How efficient is a HEPA filter?
HEPA filters have a minimum particle collective efficiency of 99.97% for particles of 0.3 µm diameter or more. A HEPA filter typically lasts three to five years, depending on hours of operation, cleanliness of the laboratory, and type of work being performed.
