Explanation:

HEPA (High - Efficiency Particulate Air) filters are specifically designed to remove particles (including microbes in some cases) from the air. They are commonly used in air purifiers, HVAC systems in hospitals, etc. Liquids have different filtration methods (like membrane filtration for some liquids). Human tissues do not use HEPA filters for microbe removal as it is an internal biological system. Medical instruments are sterilized by methods like autoclaving, not HEPA filtration.

air
