What Does Merv 11 Mean

A MERV 11 air filter has a higher efficiency rating. Meaning, it can capture finer particles and clear more contaminants out of the air.

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 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.

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.

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%.

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 does MERV 11 filter out?

MERV 11 is effective at controlling dust, pollen, dust mites, and pet dander. Applicable in most commercial buildings, residences, industrial workplaces, and paint booths.

Can I use a MERV 11 filter in my furnace?

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.

Is MERV 11 A good furnace filter?

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.

Can I replace Merv 11 with MERV 12?

In general no. In order to use a Merv 12 to replace a Merv 11, you need to know if you system can handle the extra pressure drop caused by the higher efficiency Merv 12. My heat pump/ ventilation system cannot support the pressure drop of a Merv 12.

Do HVAC filters reduce dust?

1. Change Your HVAC Air Filter Regularly. The humble air filter inside your HVAC system plays a big role in keeping dust and debris at bay. Your air filter serves as the first line of defense against dust buildup, trapping dust and other allergens before they have a chance to circulate elsewhere inside your home.

How often do you change a MERV 11 filter?

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 MERV rating do I need for pollen?

MERV 1-4: Filters with MERV ratings of 1 to 4 are generally capable of removing only large particulates such as carpet fibers, dust mites, pollen, dust, and textile fibers. MERV 5-8: MERV 5 to 8 filters routinely capture mold spores, hairspray, and even the dust from cement.

Does MERV 11 filter coronavirus?

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.

What is the difference between MERV 8 11 and 13?

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 13–16 (best): These filters are usually only found in hospitals because they can capture particles as small as 1–0.03 microns in size.

What is MERV number?

MERV stands for Minimum Efficiency Reporting Value. MERV ratings are on a scale of one to 20 depending on the minimum size of the particles a filter can be expected to capture: A filter with a MERV rating of nine to 12 captures particles greater than one micrometer. This includes most dust and common pollutants.

Can my HVAC handle MERV 12?

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.

Are allergen filters bad for HVAC?

Letting the air filter work overtime Not only that, it’s actually hurting your heating and cooling system and raising your energy bills. According to ENERGY STAR: “A dirty filter will slow down air flow and make the system work harder to keep you warm or cool—wasting energy.
