Which term is a mask filtering at least 95% of airborne particles?

• A. Protective Gloves
• B. N-95 Respirator
• C. Biological Hazard Bags
• D. Resuscitation Equipment

Answer: (B)

The key idea is protective equipment designed to filter inhaled air. The term that fits is the N95 respirator, which is designed to filter at least 95% of airborne particles when it’s properly fitted. The designation means it meets testing standards for filtration efficiency (about 95% for small particles, including most aerosols) and is meant to seal to the face to minimize leaks. That combination of high filtration and a tight seal is why it’s specifically described as filtering at least 95% of airborne particles. Other items listed aren’t designed for filtering inhaled air. Protective gloves protect the hands; biological hazard bags are for containment and disposal, not air filtration; resuscitation equipment includes devices for delivering breaths but aren’t rated to filter 95% of airborne particles.
