MERV Ratings
MERV ratings measure the effectiveness of air filters in capturing particles of different sizes. This rating, developed by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE), ranges from 1 to 20, with higher values indicating a greater ability to trap smaller particles.
Filters with a MERV rating of 1-4 are typically used in residential settings and can capture larger particles like dust and pollen. Filters rated 5-8 are generally effective for residential and commercial use, while those rated 9-16 can significantly improve air quality in environments such as schools and hospitals. Filters with ratings of 17-20 are often used in medical facilities and clean rooms, where high filtration is crucial.
| MERV Rating | Appropriate Environment | Best For |
|---|---|---|
| 5–8 | Homes and commercial settings | Basic dust, pollen, mold spore, and dander filtering |
| 10 | Schools and medical offices | Environments with allergy or asthma sufferers |
| 13 | Hospitals and higher air-quality buildings | Bacteria and smoke removal |
| 14–16 | Medical facilities and clean rooms | Filtering viruses and very fine particles |
