Which term refers to a high-efficiency filter for airborne pathogens?

• A. Resuscitation Equipment
• B. HEPA Respirator
• C. N-95 Respirator
• D. Contaminated Materials

Answer: (B)

High-efficiency filtration for airborne pathogens is provided by HEPA filters. HEPA stands for High-Efficiency Particulate Air and is rated to remove at least 99.97% of particles at the most penetrating size (about 0.3 micrometers). A respirator that uses such a filter is called a HEPA respirator. This is more stringent than an N95, which filters at least 95% of non-oil particles but does not meet HEPA’s 0.3 μm efficiency. The other options don’t describe a filtration term for airborne pathogens.
