How MERV Rating Is Determined?
Determining the MERV ranking of an air filter includes evaluating its filtering performance based on specific criteria. The MERV ranking estimation takes into account the filter's capability to catch and retain particles of differing sizes. To determine the MERV score, air filter makers subject their items to MERV score screening, which is performed in specialized labs.
During MERV rating testing, air filters are exposed to a series of particles of different sizes, consisting of dust, pollen, mold spores, pet dander, and germs. The test measures the filter's efficiency in capturing these particles and assigns a numerical value to it. The higher the MERV score, the more effective the filter is at removing airborne pollutants.
To figure out the MERV rating, the filter's efficiency is compared to a standardized referral chart. The chart specifies the percentage of particles that the filter can record at various particle size varieties. Based on the filter's efficiency, it is assigned a MERV score on a scale of 1 to 20. Filters with higher MERV scores are capable of trapping smaller particles and offering much better air quality.
It is very important to keep in mind that MERV ranking screening is performed under-regulated laboratory conditions and may not always show real-world performance. Factors such as airflow, filter loading, and maintenance can impact an air filter's effectiveness. For that reason, it is essential to think about other aspects, such as the specific requirements of your indoor environment, when picking an air filter.
