A MERV 13 filter is designed to capture a minimum of 75% of air particles that have a size between 0.3-1.0 microns. This efficiency increases to 90% or more when the size range of airborne particles is between 3 and 10 microns. The Minimum Efficiency Report Value (MERV) rating of an air filter measures how effectively it prevents dust and other contaminants from passing through the filter and reaching the air stream. MERV indices range from 1 to 16, with higher MERV indices trapping small particles more effectively than filters with lower MERV indices.
The efficiency of the filter in the three size ranges is compared to a MERV graph and the final MERV value is the highest value when the filter meets the three MERV requirements. The ratings do not exceed those of the MERV 16, but high-efficiency particulate air (HEPA) filters trap even smaller particles at a speed even higher than that of the MERV 16. These filters are generally used in surgical operating rooms, clean rooms, and other contexts that require absolute cleaning. When it comes to air filtration, it's important to understand what size particles a MERV 13 filter can capture. This type of filter is designed to capture particles that are between 0.3-1.0 microns in size, with an efficiency rate of 75%.
When it comes to particles between 3-10 microns, the efficiency rate increases to 90% or more. The MERV rating system is used to measure how well an air filter can prevent dust and other contaminants from passing through it and entering the air stream. The ratings range from 1 to 16, with higher ratings trapping smaller particles more effectively than filters with lower ratings. Although the ratings do not exceed those of the MERV 16, HEPA filters are able to trap even smaller particles at a speed higher than that of the MERV 16. When selecting an air filter, it's important to consider what size particles you need to capture.
A MERV 13 filter is designed to capture particles between 0.3-1.0 microns in size, with an efficiency rate of 75%. For particles between 3-10 microns, the efficiency rate increases to 90% or more. HEPA filters are able to trap even smaller particles at a speed higher than that of the MERV 16.
