MERV is an abbreviation for Minimum Efficiency Reporting Value. The MERV rating of furnace air filter indicates how well it catches microscopic particles that you don’t want to escape into your home, such as dust, pollen, mold, and other irritants. The MERV rating of a filter determines how effective it is in trapping airborne particles. The greater the MERV rating, the better. The lowest potential performance of any filter is represented by its MERV rating.

How Does the MERV Scale Work?

The scale ranges from 1 to 16, with 1 indicating a filter’s capacity to capture particles between 0.3 and 10 microns. A higher MERV grade means a higher percentage of particles are captured on each pass. This value is useful for selecting dust collector filters with the necessary starting filtration efficiency, but it doesn’t tell you anything about how the filters or the collector as a system will function.

Why aren’t MERV ratings helpful when it comes to selecting dust collector filters?

It’s not very practical because MERV ratings only apply to new filters and their initial filtering level in a static environment. Dust collectors and their filters, on the other hand, regulate emissions over time in a dynamic system.

The Advantage of Using Filters with the Highest MERV ratings:

The MERV rating is determined by comparing the filter’s efficiency to the particle size it can trap. While higher MERV ratings are more efficient, household filters should have a MERV rating of between MERV 7 and MERV 13. Most of the airborne pollutants present in residential units may be eliminated using a MERV 7 or MERV 13 air filter. Reach out to the experts for furnace repair in Queens.

What MERV Rating can your HVAC handle?

Because it is the most effective at keeping your home’s air clean and pure, the EPA recommends MERV values of 9-12. Particulates as fine as 1 micron will not enter your HVAC system if you use a filter with this grade. This level is considered HEPA (high-efficiency particulate absorption).

Why is it necessary for a MERV rating to include the air velocity through the filter?

The reason an MERV specifies the air velocity through the filter is because the filter efficiency decreases as the velocity increases.

MERV Ratings Breakdown:

MERV 6-8

The cheapest furnace filters are those with MERV ratings of 6-8, which are considered the basic minimum of efficiency. MERV 6-8 filters keep your HVAC system safe, but they aren’t the best at capturing huge amounts of airborne particles.

MERV 8-10

Comparatively affordable, these air filters are ideal for residential homes. MERV 8-10 filters can trap more of the large particles and at least half of the smaller particles like pollen, mold, and mildew spores.

MERV 11-13

MERV 11-13 air filters are a suitable middle ground between cheap and expensive air filters. They can collect almost all of the larger particles, alongside most of the smaller ones.


The finest air filters for household HVAC systems are MERV 13 air filters. MERV 13 air filters are routinely used in schools to create clean learning environments for students and staff.

MERV 14 and higher

These air filters are quite efficient; however, they are not recommended for use in homes. They are massive and bulky, primarily designed for heavy duty filtration in hospitals and clinics.
