You can use air cleaners equipped with high efficiency particulate air (HEPA) filters to reduce crew member exposures to the coronavirus.
That’s your takeaway from a recent experiment conducted by the Health Effects Laboratory Division of the National Institute for Occupational Safety and Health. Researchers used respiratory simulators to mimic a person with COVID-19 and other, uninfected people in a 584- square-foot room, and then positioned two air cleaners with HEPA filters in four locations.
They found that the use of the HEPA-equipped cleaners reduced exposures to aerosol particles by 65%.
They also learned that the combination of masks and air cleaners with HEPA filters lowered particle exposures by 90%.
