Merv Air Filter

Merv otherwise known as minimum efficiency reporting value is a measurement scale that rates the effectiveness of filters at trapping airborne particles.

Merv air filter.

The scale ranges from 1 16 with 16 being the most effective. Merv stands for minimum efficiency reporting value. 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. Filters with a merv 11 rating have a dust spot efficiency of 60 65 and are 30 times more.

It is an acronym for high efficiency particulate air filter as officially defined by the u s. Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings. Micro dust merv 13 replacement for trion air bear 259112 102 and 255649 102 air filter 2 pack. 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 8 rated filters are high quality filters. With a dust spot efficiency of 30 35 they are 20 times more efficient than regular fiberglass filters. 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.

An air filter s merv rating is a scale from 1 16 that describes the minimum efficiency of the air filter. Merv 8 filters remove basically the same particulates as a merv 6 but they are more efficient. Higher value merv rating equates to finer filtration meaning fewer dust particles and other airborne contaminants can pass through the filter. Some of the common particles that filters are tested for include pollen dust mites textile.

The merv rating system is intended to be used to determine the filter s ability to remove particulates from the air.
