Answer:

The HEPA filter removes particulates (generally called aerosols) such as micro-organisms, from the air. The HEPA filter does not remove vapors or gases. HEPA filters used in clean benches and biosafety cabinets should have a minimum filtration efficiency of 99.99% against airborne particles 0.3 microns in size.
