What is the MERV Rating System?
The Minimum Efficiency Reporting Value (MERV) rating system is a standard measure used to rate the effectiveness of air filters. It was developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) to help consumers understand the efficiency of various air filters.

How Does the MERV Rating System Work?
The MERV rating system assigns a value between 1 and 20 to air filters, with a higher number indicating a higher level of effectiveness in removing airborne particles. The rating is determined based on the filter’s ability to capture particles of different sizes, ranging from large dust particles to microscopic contaminants.
Understanding MERV Ratings
Filters with a MERV rating of 1 to 4 are considered to have low efficiency and are typically used in residential settings to protect HVAC systems from large particles. Filters with ratings of 5 to 8 offer better filtration and are suitable for residential and commercial use. Filters with ratings of 9 to 12 provide even higher efficiency and are commonly used in commercial and industrial settings. Filters with ratings of 13 to 16 offer exceptional filtration and are often used in hospitals and other high-risk environments. Finally, filters with a MERV rating of 17 to 20 are extremely efficient and are typically used in clean room environments such as pharmaceutical manufacturing facilities and electronics manufacturing plants.
Choosing the Right MERV Rating
When selecting an air filter, it’s important to consider the specific needs of the environment where it will be used. For residential purposes, a filter with a MERV rating of 8 to 13 is typically sufficient to maintain indoor air quality. Commercial and industrial settings may require filters with higher MERV ratings, especially in areas where air quality is a critical concern. It’s important to note that using a filter with too high of a MERV rating for a given system can lead to reduced airflow and system strain, so it’s crucial to consult with an HVAC professional when selecting the right filter for a specific application.
Benefits of Higher MERV Ratings
Filters with higher MERV ratings offer superior indoor air quality by capturing a wider range of airborne particles, including allergens, bacteria, and viruses. This can be particularly beneficial for individuals with respiratory issues or allergies. Additionally, high MERV rated filters can help prolong the life of HVAC systems by preventing the buildup of debris and contaminants within the system.
