At the end of this Fact Sheet, you will find a list of questions you should ask before purchasing a Gas Mask or Escape Respirator. Both are built on the premise that infectious respiratory viruses like SARS-CoV, SARS-CoV-2, MERS-CoV, and influenza are, COVID-19 and flu are spread by aerosol inhalation. This specific capability is one reason why the governing agencies, namely the NIOSH and OSHA, require employees to wear it for their ultimate safety and protection. The most important variables are filter efficiencyhow well the filter collects particles of all sizes; fithow well the facepiece prevents leakage around the edges; and breathing resistancehow easy it is to inhale and exhale through the filter.

Make sure it covers both your nose, mouth and chin. Respirators have very effective filters and are designed to fit most faces. A healthcare study with a non-randomized control group and full-time wearing of the interventions has clearly demonstrated that respirators are superior to surgical masks in preventing respiratory illness.32 But this study was ignored and its findings diluted by combining it with dissimilar investigations. Tang S, Mao Y, Jones RM, et al. While only 3% to 10% of the wearers were able to achieve a fit factor of 100, a strong majority (76% to 86%) were able to achieve a fit factor of 10. Surgical mask vs N95 respirator for preventing influenza among health care workers: a randomized trial. The filter tests required by the US Food and Drug Administration are not predictive of surgical mask filter performance, so it's impossible to know which surgical mask filters can collect small particles.15,16 Surgical masks are not expected to fit tightly against the face, so they have considerable inward and outward leakage of particles. Environ Int 2020 (published online Apr 10), 5. We wear the mask for short periods of time and change it out at the first signs of the excessive moisture build-up that we know degrades mask effectiveness and increases their negative effects.

Consideration of the aerosol transmission for COVID-19 and public health. In fact, studies have found that infection rates for healthcare workers wearing respirators in intensive care units with COVID-19 patients are much lower than in other healthcare settings.2325 This fact alone demonstrates that respirators and other measures such as negative-pressure rooms will protect healthcare workers from SARS-CoV-2 aerosols. BMC Infect Dis 2020;20(1):853 doi:10.1186/s12879-020-05587-2, 24.
