Lincoln said there are two ways to measure the size of particles: investigating their mass and measuring their physical size, like calculating the diameter of a ball. Official guidelines from the CDC indicate that most masks are unable to filter out particles as small as those causing smoke, and Ive seen a lot of angry claims that if masks cannot filter out smoke, they surely must not be effective against viruses such as SARS-CoV-2. Lincoln offered this sense of scale: A typical virus particle is about 250 to 400 nanometers long (a nanometer is a billionth of a meter, or 10^-9 m), and the typical atomic nucleus measures about .
