For airborne infections, which protective equipment is recommended?

• A. N95 respirator
• B. Cloth mask
• C. Surgical mask
• D. Full face shield

Answer: (A)

Airborne infections require protection that both filters out very small particles and creates a tight seal around the nose and mouth. An N95 respirator is designed for this purpose, filtering at least 95% of airborne particles when properly fitted and seal-checked. It is the standard choice for protecting the wearer from inhaling infectious aerosols, often used with an airborne isolation setup to minimize exposure. Cloth masks have variable filtration and do not reliably block aerosols. Surgical masks protect against large droplets and splashes but do not provide a reliable seal against airborne particles, so they aren’t sufficient for airborne precautions. A full face shield protects the eyes and face from splashes, but it does not seal the face or filter inhaled air, so it cannot replace an N95 for airborne protection. So, the best choice for airborne infections is the N95 respirator, used with proper fit testing and seal checks to ensure effective protection.
