Protecting against airborne infections requires both a respirator that filters aerosols and barriers that prevent contact with contaminated surfaces. An airborne pathogen can be inhaled through the lungs, so a high-filtration respirator that seals to the face is essential. At the same time, protecting skin and clothing from potential contact with contaminated materials is important, which is why gloves and a gown are included. A surgical mask or regular eye protection alone doesn’t provide adequate filtration for airborne particles, and a respirator without barrier protection misses the risk from contact with contaminated surfaces. The combination of a high-filtration respirator (HEPA-style) with gloves and a gown gives simultaneous protection against inhalation of aerosols and contact transmission, making it the best option in this scenario.
