Merv Air Filter

Micro dust merv 13 replacement for trion air bear 259112 102 and 255649 102 air filter 2 pack.

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. Hepa is a type of pleated mechanical air filter. Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings. Merv 8 filters remove basically the same particulates as a merv 6 but they are more efficient.

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. The merv rating system is intended to be used to determine the filter s ability to remove particulates from the air. Filters with a merv 11 rating have a dust spot efficiency of 60 65 and are 30 times more. Minimum efficiency reporting value merv is a standard that rates the overall effectiveness of air filters.

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. The scale ranges from 1 16 with 16 being the most effective. 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. Here s an in depth description of the process used to determine merv from the national air filtration association.

Merv 8 rated filters are high quality filters. Some of the common particles that filters are tested for include pollen dust mites textile. It is an acronym for high efficiency particulate air filter as officially defined by the u s. 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.
