Understanding MERV Ratings

MERV (Minimum Efficiency Reporting Value) is a scale that measures the effectiveness of air filters in capturing particles between 0.3 to 10 microns. The MERV scale ranges from 1 to 16, with higher numbers indicating better filtration. For example, a MERV 16 filter captures over 95% of particles. Field Controls offers Media Air Cleaner Cabinets with MERV 8, MERV 11, and MERV 13 ratings, allowing you to choose the right level of filtration for your needs.
