• Respirators are your best option for protecting healthcare and different frontline employees, but not really helpful for source control. The valve does absolutely nothing to forestall transmission from contaminated wearers to different nearby people. I would recommend the authors embody references to masks with valves. Many of the investigations included on this review did not carry out filter or match tests appropriately. For example, the article by Davies et al. didn’t problem the filters with small particles.
