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. The merv rating system is intended to be used to determine the filter s ability to remove particulates from the air. Here s an in depth description of the process used to determine merv from the national air filtration association. Filters with a merv 11 rating have a dust spot efficiency of 60 65 and are 30 times more.

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 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. 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. 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. Merv 8 rated filters are high quality 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. With a dust spot efficiency of 30 35 they are 20 times more efficient than regular fiberglass filters. Hepa is a type of pleated mechanical air filter. Minimum efficiency reporting value merv is a standard that rates the overall effectiveness of air filters.

Merv 8 filters remove basically the same particulates as a merv 6 but they are more efficient.
