HEPA filters can protect against which hazard?

Explanation:
HEPA filters remove solid particles from the air as air passes through the filter material, using mechanisms like interception, impaction, and diffusion to trap tiny particles. Because many pathogens travel in airborne droplets or aerosols, a properly installed HEPA filter can significantly reduce the concentration of bacteria and viruses in a space, lowering exposure risk. They do not remove gases or vapors, so they’re not effective for chemical hazards or odors. They also don’t affect oxygen levels or offer protection against heat; those require different controls or equipment. Proper sealing, fit, and maintenance are essential to ensure the filter actually provides the intended protection.
