What does MERV 11 mean?

MERV stands for Minimum Efficiency Reporting Value, and it is used to tell how well an air filter can catch and trap particles in your home’s air. The higher the MERV rating, the more efficient the air filter is at trapping tiny, harmful air borne particles in your home’s air.
