Best answer: Does air filter reduce airflow?

“A dirty filter will slow down air flow and make the system work harder to keep you warm or cool—wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.”

Do air filters restrict airflow?

All filters will restrict the air flow to some extent because, in every case, the air has to move through the filter for the unit to be able to remove the particles in the atmosphere. The higher the MERV rating, the denser the filter is going to be, and so the more restricted air flow will become.

Do higher for filters restrict airflow?

Generally, a filter with a higher MERV rating will reduce airflow. However, there are many other factors at play such as the size of the filter and the type of blower motor in your HVAC system.

Do MERV 11 filters restrict airflow?

A MERV 11 air filter has a higher efficiency rating. … Air filters with higher MERV ratings can filter more, but the thickness of the filter material can restrict airflow. Restricted airflow can decrease comfort, increase energy use, and accelerate the wear and tear of HVAC components.

Do pleated air filters restrict airflow?

Because they restrict airflow to your HVAC system. Pleated, high-MERV filters definitely capture a lot of pollutants, but they also restrict the movement of air into your blower or furnace. … These cover all the air filtration basics – dust and pollen removal, for example – without restricting airflow.

Is MERV 13 too high?

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.

Is MERV 14 too high?

MERV 14 is too strong for most home HVAC systems.

And these are some of the best on the market. … MERV is an industry-standard, or rating. The abbreviation stands for Minimum Effective Reporting Value. In other words, it’s a measurement showing how small the holes are in the filter.

Are pleated air filters bad for your HVAC system?

Pleated filters are bad for your system because they block too much air, forcing the HVAC motor to work harder to pull in the air it needs and burning it out faster.

Do HEPA filters restrict airflow?

HEPA filters are the gold standard in hospitals and clinics because they remove not only inorganic dust, but microorganisms such as mold spores, bacteria, pollen, dust mites and many viruses. … As filtration efficiency increases, so does restriction to system airflow caused by the filter.

Does MERV 13 restrict air flow?

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 can my HVAC handle?

The EPA recommends MERV ratings of 9-12 because it is the most effective at keeping your home’s air clean. A filter with this rating will prevent particulates as small as 1 micron from entering your HVAC system. This rating qualifies as HEPA (high-efficiency particulate absorption) level.

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.

Do air filters make a difference house?

At its most basic function, an air filter removes impurities such as dust, pet dander or even bacteria from the air flowing through the system. Not only does this improve the air quality within your home, but it also protects your HVAC system from damage.

Why are air filters pleated?

By pleating the media, these filters can have an increased surface area and density while minimizing the reduction in airflow. In other words, pleated filters can collect more particles than standard throwaway filters without increasing your air conditioner’s energy consumption.

Is there really a difference in home air filters?

The short answer is, no, they’re not all the same. In fact, there are many different types of air filters available and choosing the right one can make a real difference in the lifespan of your HVAC system. … You see, the higher the MERV rating, the more the filter restricts air flow.
