Is there a downside to high MERV filters?

Is there a downside to high MERV filters?

The higher the MERV rating, the fewer particles and other contaminants will be allowed into your home. 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.

What MERV rating can my furnace handle?

The ideal MERV filters for both air filtering and furnace efficiency are 7-13, experts say. These filters can be used without any modifications to your equipment. Your system may handle MERV 14-16 with no discernable stress. However, many residential systems require modifications to pull air through these filters.

Is MERV 11 too restrictive?

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. In most cases, a MERV 11 air filter isn’t too high for residential use.

Is MERV 12 too high for HVAC?

9-12 MERV – These filters are more efficient and usually offer the best indoor air quality improvement for residential applications. Deep pleated filters fall into this category. Because they work so well at removing airborne pollutants, they must be regularly checked to ensure proper airflow.

What MERV rating should I get for home?

As a general rule, residences do not use higher than MERV 8 filters. We do recommend that everyone uses filters that have at least an 8 MERV rating. These filters will remove the majority of pollutants from your indoor air.

Is MERV 8 good enough for Covid?

Filters with MERV-13 or higher ratings can trap smaller particles, including viruses. Many home HVAC systems will have a MERV-8 filter installed as the default. By itself, using an upgraded HVAC filter is not enough to protect people from COVID-19.

What MERV rating is filtrete 1500?

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 7 good enough?

For most residential systems, experts suggest using an air filter with a MERV value between 7 and 12. These filters offer adequate filtration and remove common contaminants such as pollen, mold spores, dust, pet dander, and tobacco smoke.

What MERV rating do I need for Covid-19?

What does MERV rating mean on Furnace filter?

The rating indicates the size of particles the air filter is designed to capture. Ranging from 1 to 20, the larger the number, the better the filter is at catching small particles. What MERV Should I Use in My Home Furnace?

Which is better a higher Merv or lower Merv?

Higher = More Filtration in the MERV Filter Rating Chart Generally, the higher the MERV (M), you get better filter performance. M values 1 through 4 are designed to remove large particles. These filters are used primarily to protect equipment.

How big does a Merv 11 filter need to be?

A MERV 11 filter only needs to stop 20% of particles in the 0.3 to 1.0 micron (three to ten times bigger than a COVID-19 particle), a MERV 12 only needs to stop 35% of particles under 0.3 micron, and a MERV 13 only needs to stop half.

What should I look for in a furnace filter?

For residential furnaces, filters range from 4 to 12 on the MERV scale. A basic MERV 4 filter will likely be the cheapest but won’t catch certain small particles (like dust mites and pet dander) that could be in your home. 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.
