What does HEPA stand for?

HEPA stands for High Efficiency Particulate Air. This term refers to a type of air filter that can trap a high percentage of very small particles, including dust, pollen, mold spores, and even certain bacteria and viruses. Specifically, to qualify as a HEPA filter, it must be able to filter out at least 99.97% of particles that are 0.3 microns in size.

In environments where asbestos handling takes place, the importance of HEPA filters cannot be overstated. They are crucial for maintaining air quality and ensuring that airborne contaminants, including asbestos fibers, are adequately captured and not inhaled by workers or released into the environment. This capability is central to safety standards in industries where hazardous materials are handled, making the use of HEPA filters a vital part of protective measures.
