Quizplus · Accepted Answer

Both HEPA filters and ultraviolet light can be used to disinfect air. HEPA filters trap and remove airborne particles, including viruses and bacteria, while ultraviolet light kills the microorganisms. As a result, using both methods together can significantly reduce the number of harmful pathogens in the air. Ethylene oxide, on the other hand, is a chemical sterilant that is typically used to disinfect medical equipment and supplies, but is not recommended for air disinfection.
