MERV Rating

MERV stands for Minimum Efficiency Reporting Value. It is a rating system that measures the effectiveness of air filters in trapping airborne particles. The MERV rating scale ranges from 1 to 20, with higher numbers indicating a higher level of filtration. In the context of space and astronautical engineering, MERV ratings are important for maintaining clean air in spacecraft and space stations. Air filters with high MERV ratings are necessary to remove harmful particles and contaminants from the air, which can be especially important for the health and safety of astronauts during long-duration missions. Additionally, MERV ratings are used in the design and testing of life support systems for space habitats and vehicles.
