How masks work A basic understanding of how masks work helps. Masks are filters. The material used in a standard surgical mask (by far the more common type of mask) reduces transmission of bacteria. Both bacteria and viruses are microscopic microbes, but they differ greatly. Bacteria are living cells, while a virus is a particle that requires a host cell to replicate. A coronavirus virion (particle) is spherical, averaging around 125 nanometers in diameter. Compare that to bacteria’s 1,000-nm size. It’s a grape compared to a grapefruit. A surgical mask whose purpose is to block bacteria will do little to prevent passage of the smaller coronavirus particle. That’s why N95 masks, which block 95% of all airborne particles, are the gold standard in hospitals treating COVID-19 patients. They have a much more selective filter. … [Read more...] about Why masks aren’t better at protecting us from viruses
