How To Choose A Merv Level Filter？

What does merv mean in filter？

MERV (Minimum Efficiency Reporting Value)is a standard used to measure the efficiency of air filters. This value was developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to evaluate a filter's ability to capture particles of different sizes.

MERV numbers range from 1 to 20, with higher numbers making the filter more efficient and capturing smaller particles.

What level of MERV filter should I use?

MERV 1-4: Minimum efficiency filters for homes and commercial buildings that capture larger particles such as pollen and dust.

MERV 5-8: A more efficient filter for homes and commercial buildings that captures smaller particles such as mold spores and pet dander.

MERV 9-12: High-efficiency filter suitable for use in places such as hospitals and laboratories to capture smoke and fine dust.

MERV 13-16: Very efficient filter for use in clean rooms and operating rooms, capable of capturing extremely small particles such as bacteria and smoke.

MERV 17-20: The most efficient filter, typically used in industrial settings or special applications such as the electronics manufacturing and pharmaceutical industries, to capture ultrafine particles and viruses.

Choosing the appropriate MERV-rated filter depends on the specific application and the types of particles that need to be filtered. In general home and office environments, MERV 8-12 filters can already provide quite good air quality protection.
