Can HEPAs Filter Out Everything?

HEPA filters are the main line of defense against contamination for biological safety cabinets. They capture particles using three methods:

• Inertial impaction rapidly changes air direction to separate particles from the air stream
• Interception forces particulate matter to make contact with the filter matter
• Diffusion occurs when the random motion of particulate matter results in contact with the filter
