Is MERV 11 too high for home?

In most cases, a MERV 11 air filter isn't too high for residential use. Generally speaking, anything under a MERV 13 air filter should provide very efficient air purification in a home without impacting airflow.

Will MERV 11 hurt 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.

Does MERV 11 restrict airflow?

Be aware, too, that some retailers also use their own rating system instead of MERV. 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).

Is MERV 11 good enough for Covid?

What kind of filter should I use in my home HVAC system to help protect my family from COVID-19? 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.

Can MERV be too high?

If the MERV rating on your furnace is too high, it may force your furnace to work too hard and leave it vulnerable to damages. In addition, you may not get the air velocity required to reach all parts of your home leaving inconsistencies in temperature.

Is MERV 11 or 13 better?

MERV 11 furnace filters have a particle arrestance of a little over 90%. In comparison, MERV 13 HVAC filters have a particle arrestance of around 98%. Naturally, it is significantly more efficient. MERV 11 rated air filters are ideal for those who live in a moderately polluted area, have mild allergies, or own a pet.

What MERV rating should I use in my house?

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.

Which air filter is best for Covid?

The longer they run, the more particles they will likely remove. When assembling a DIY air cleaner, choose a high-efficiency filter, rated MERV 13 or higher, for better filtration.

Will MERV 13 damage my furnace?

What Are MERV 13 Air Filters? 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.

How often should you change a MERV 11 filter?

Which filter is better MERV 8 or 11?

A MERV 11 rated filter captures 85% or better of particles between the sizes of 0.3 and 10 microns. This may not seem like a significant difference compared to the MERV 8 filter, but a MERV 11 is also more capable of capturing between 65% and 79% of smaller particles.

Is MERV 12 better than MERV 11?

MERV rating 9-12

Filters in this range can trap more than 85% of the particles sized 3.0-10.0 microns. 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%.

What MERV filter does carrier recommend?

Selecting a good quality filter with 12 – 16 MERV to remove a high percentage of offending particulates. Be sure to check your filter at a minimum of once per month.

What MERV Can my furnace handle?

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. US Department of Energy recommends MERV 13.

Can air filters be too restrictive?

Burnt out motors and controls can result from too-restrictive filters. Coils, motors, and blowers can also easily become clogged by weak filters creating higher fan usage resulting in higher energy costs.

How much MERV do I need?

If your family has health or allergy issues, then you may want to look for a high-efficiency filter that's MERV 11 or higher. But for most households, a MERV 7 or 8 filter might be the sweet spot between performance and cost.

Is MERV better than HEPA?

High Efficiency Particulate Air or HEPA have an even higher performance than MERV 16. While a MERV 16 filter captures >95% of particles in the entire test range (0.3-10.0 microns), a HEPA filter captures 99.97% of particles with a size of 0.3 microns.

Are MERV 13 filters worth it?

A MERV 13 filter is a step in the right direction and captures more particles than a typical MERV 8 filter. However, it is not as good at capturing small virus sized particles like a HEPA can. 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).

Why are the highest rated MERV filters not used in residential applications?

What is MERV 11 air 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.

What's the difference between MERV 11 and MERV 16?

The higher the MERV number, the smaller the holes, and fewer airborne particles can pass through.
