Merv Air Filter

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.

Merv air filter.

Merv 8 filters remove basically the same particulates as a merv 6 but they are more efficient. The scale represents a quantum leap in the precision and accuracy of air cleaner ratings and allows for improved health reduced cost and energy efficiency in. Merv 8 rated filters are high quality filters. Minimum efficiency reporting value merv is a standard that rates the overall effectiveness of air filters.

Minimum efficiency reporting value commonly known as merv is a measurement scale designed in 1987 by the american society of heating refrigerating and air conditioning engineers ashrae to report the effectiveness of air filters. Higher value merv rating equates to finer filtration meaning fewer dust particles and other airborne contaminants can pass through the filter. Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings. The merv rating system is intended to be used to determine the filter s ability to remove particulates from the air.

The scale ranges from 1 16 with 16 being the most effective. Micro dust merv 13 replacement for trion air bear 259112 102 and 255649 102 air filter 2 pack. Filters with a merv 11 rating have a dust spot efficiency of 60 65 and are 30 times more. Merv otherwise known as minimum efficiency reporting value is a measurement scale that rates the effectiveness of filters at trapping airborne particles.

Here s an in depth description of the process used to determine merv from the national air filtration association. Hepa is a type of pleated mechanical air filter. Merv stands for minimum efficiency reporting value. An air filter s merv rating is a scale from 1 16 that describes the minimum efficiency of the air filter.

It is an acronym for high efficiency particulate air filter as officially defined by the u s.
