The effectiveness of air filters in stopping dust and other contaminants from entering the air stream is measured by their Minimum Efficiency Reporting Value (MERV) rating. The higher the filter rating, the better the filter is at trapping small particles. Usually, a MERV 16 rating or lower is appropriate for homes, businesses, and general hospital facilities. However, for those locations requiring utmost cleanliness, such as surgical operating rooms and clean rooms, then filters with a MERV 17 to 20 rating should be used.
