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.

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. Minimum efficiency reporting value merv is a standard that rates the overall effectiveness of air filters. Some of the common particles that filters are tested for include pollen dust mites textile.

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. Here s an in depth description of the process used to determine merv from the national air filtration association.

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. Micro dust merv 13 replacement for trion air bear 259112 102 and 255649 102 air filter 2 pack. Filters with higher merv ratings trap small particles more effectively than filters with lower merv ratings. Higher value merv rating equates to finer filtration meaning fewer dust particles and other airborne contaminants can pass through the filter.

Hepa is a type of pleated mechanical air filter. 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. Merv 8 filters remove basically the same particulates as a merv 6 but they are more efficient. It is an acronym for high efficiency particulate air filter as officially defined by the u s.

Merv 8 rated filters are high quality filters.
