Air Filtration and the Use of HEPA Filters in Biological Safety Cabinets

Efficient, high-quality, air filtration is instrumental in meeting occupational safety requirements, addressing environmental concerns, or improving indoor air quality in the home. Control of airborne particulate in
indoor environments is critical to develop quality products, protect employees from contact with hazardous materials, or prevent health problems from prolonged exposure to allergens. How airborne particulate is controlled varies from industry to industry and from an occupational setting to a home environment. To better understand why HEPA filters are used in the biological safety cabinet industry, it is necessary to explore particle sizes, types of filters available for home and occupational use, efficiency and penetration, filter standards, and performance testing.
