CDC advises health-care workers to “consider the addition of portable solutions" (e.g., portable HEPA filtration units, air purifiers)
HEPA-rated media provides superior performance for removing virtually 100% of particulates.
Purafide H13 HEPA Filters Capture Covid-19 Airborne Virus, including the Omicron Variant.
Size of Covid-19 virus particles measure between 0.12 and 0.16 microns. The virus itself attaches to droplets when airborne, which are larger than 1 micron.
Purafide H13 HEPA Filters will capture particles down to 0.1 microns. This captures the Covid virus and variants.
“There is never a naked virus floating in the air or released by people,” said Linsey Marr, a professor of civil and environmental engineering at Virginia Tech who specializes in airborne transmission of viruses. "The virus attaches to water droplets or aerosols (i.e. really small droplets) that are generated by breathing, talking, coughing, etc. These consist of water, mucus protein and other biological material and are all larger than 1 micron." -USA Today on 06/12/2020
