Do higher MERV filters 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.

Is a MERV 13 filter 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.

Does MERV 11 restrict airflow?

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

the thickness of the filter material can restrict airflow

.

What MERV rating do I need for Covid 19?

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.

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.

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 MERV rating is best for air flow?

If your unit is older and/or very sensitive with airflow, use a filter that ranks from MERV 1 up to possibly MERV 6. If you want your air to at least be cleaned and handle dust, mold, pollen, and bacteria, then a

MERV 8

will do the job.

What MERV rating is filtrete 2200?

How often should I change a MERV 13 filter?

Change Filters Often

For Merv 8, 11 and 13 filters, we recommend that you change your filter

at least every 3 months

, however changing your filter every 2 months provides better filtration which provides healthier and cleaner air in your home.

Is MERV 13 bad for HVAC?

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.

What MERV rating is a HEPA filter?

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 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

.

Is a 2 inch filter better than a 1 inch?

Most air filters are 1 inch thick, but some systems can accommodate filters 2 to 5 inches thick. In our tests, we found that the

thicker the filter

, the better it works and the longer the replacement intervals. That means it’s better for you and for your heating, ventilating, and air conditioning (HVAC) system.

What MERV rating is filtrete 1500?

Each Filtrete Healthy Living 1500 filter has a microparticle performance rating (MPR)

of 1550

, which is comparable to a MERV 12 rating. This is one of the highest residential MERV ratings, which were created by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
