However, some particle mixtures were composed with larger particles up to 1000 micron, but with a fraction of smaller particles down to 200 microns at the same time. This shows the effect of strong drag from early fluidizing smaller particles. The

Although positive RNA samples indicated the infectious virus possibility, except in sub-micron-sized particles, the results of cell culture were inconclusive (Santarpia et al., 2020). Recently, an important study was able to measure the infectious virus using the "gentler" collection method ( Lednicky et al., 2020 ).

Clearly a media with a ratio of Beta 1000 is far more efficient than one with a rating of Beta 2 on that given particle size. Your shirt sleeve may well have a Beta ratio higher than 2000 on particles the

The D50 number mean that 50% of the particles that were measures are larger than this number, and 50% were smaller. So, if a particle when measured you may have a D50 of, say, 4 microns. (Usually written as D50= 4 microns.) This means half the particles were over 4 and half were under.

Particles from 1 to 1,500 microns are produced in different sizes: particles below 100 microns, around 400 microns and larger than 800 microns. A grinder can never produce 100% of particles of the same size, but they are more or less accommodated in a few micron ranges. This is called grind distribution.
