Industrial dust collectors are proven engineering control systems to maintain indoor air quality and protect the health and safety of your workers. One of the key factors to keeping your dust collector operating efficiently over its lifetime is selecting the right dust collector filters. Many replacement dust collector filters offer MERV (Minimum Efficiency Reporting Value) ratings to quantify filter efficiency. MERV ratings are very useful in the HVAC industry, with higher ratings generally indicating superior filtration. However, MERV ratings don’t reflect how well a filter will perform in the active environment of an industrial dust collection system.
