Air filter merv rating 11.

Many new jersey homeowners ask us about merv ratings especially when it comes to choosing between merv 8 and merv 11 air filters. The merv rating system is intended to be used to determine the filter s ability to remove particulates from the air. The chart below shows the merv ratings corresponding particle size ranges and efficiency level as measured by the percentage of particles captured. This type of air filter can theoretically remove at least 99 97 of dust pollen mold bacteria and any airborne particles with a size of 0 3 microns µm.

An air filter s merv rating is a scale from 1 16 that describes the minimum efficiency of the air filter. Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings. An air filter s minimum efficiency reporting value merv rating measures how effectively the filter stops dust and other contaminants from passing through the filter and into the air stream. A low merv rating means that the filter does not remove as many particulates from the air.

Merv 11 filters can filter particles as small as 0 3 micron or pm0 3. As the merv rating increases the finer the filtration becomes. What is a merv rating. In this article we ll go into more detail about merv filters and how to choose the right one for your new.

Hepa is a type of pleated mechanical air filter.

It is an acronym for high efficiency particulate air filter as officially defined by the u s. Merv means minimum efficiency reporting value merv and is an industry standard that measures the overall effectiveness of air filters. Think of merv 8 filters as a good option and merv 11 filters as the better option for normal residential use. Mpr microparticle rating is a rating system that includes microscopic particles not visible to the naked eye.

Note with poor air quality more frequent filter changes will be needed. The higher the merv rating on a filter the fewer dust particles and other contaminants that can pass through it. At 3m we believe merv only tells part of the story. Our filters are available in three grades merv 8 merv 11 and merv 13.
