Getting to Know MERV

MERV (minimum efficiency reporting value) is a measurement scale to rate the effectiveness of air filters. The scale allows for improved health, reduced cost and energy efficiency in heating, ventilation and air conditioning design. The scale ranges from 1 to 20. The higher the rating, the greater filtration achieved. A MERV 16 filter captures more than 95% of particles.

 

Residential window A/C units generally use air filters rated 1-4. These filters help to control pollen, dust mites, cockroach debris, sanding dust, spray paint due, textile fibers and carpet fibers.

 

Better residential air-conditioning units and general, commercial and industrial workspaces generally use air filters rated 5-8. These filters help to control the things that a 1-4 rating does, as well as mold, spores, dust mite debris, cat and dog dander, hair spray, fabric protector, dusting aids and pudding mix.

 

Superior residential air-conditioning units and better commercial, better commercial workspaces and hospital laboratories generally use air filters rated 9-12. These filters help to control the things that a 1-8 rating does, as well as Legionella, humidifier dust, lead dust, milled flour, auto emission particulates and nebulizer droplets.

 

Hospital and general surgery air conditioning units generally use air filters rated 13-16. These filters help to control the things that a 1-12 rating does, as well as bacteria, droplet nuclei, cooking oil, most smoke and insecticide dust, most face powder and most paint pigments.

 

Electronics and pharmaceutical manufacturing clean rooms generally use air filters rated 17-20. These filters help to control that a 1-16 rating does, as well as viruses, carbon dust, sea salt and smoke.
