A controlled crossover human volunteer study of the in vivo filtration efficacy of a high-efficiency particulate air-filtering oxygen mask.
Am J Infect Control. 2011 Nov; 39(9):782-4.AJ

Abstract

Nosocomial airborne disease transmission can be important in some epidemics. An oxygen mask incorporating a high-efficiency particulate (HEPA) filter may reduce the chance of inhaling airborne particles. In a randomized controlled crossover volunteer study, the median ratio of ambient:intramask 0.02 to 1-μ particles was significantly higher for the HEPA oxygen mask than for a Hudson-type mask (P < .001), and was ≥100 in 59%-64% of subjects. The use of HEPA masks may protect patients receiving supplementary oxygen against airborne pathogens.
