1. A “COVID-19” virus’s diameter varies from 60 to 140 nm (nano metres) or 0.14 μm [0], according to the New England Journal of Medicine. [1]

2. The highest efficiency masks, as rated according to the NIOSH classifications, are tested against 0.3 μm (300 nm) particles. [2]

3. There are claims that, quote ‘particles with a size both less than and greater than 0.3 μm are filtered at an efficiency greater than 99.97%’. [2]

4. There are claims by the CDC, that ‘COVID-19’ viruses ‘travel’ not as individual detached entities, but attach themselves to droplets of 5 µm in size. [3]


5. Claims 3. and 4. lack provable empirically derived data open to universal review and scrutiny.

6. In particular, Claim 3. should demonstrate how many of the < 0.3 μm particles go through and how many get filtered. The main thrust of Claim 3.’s argument for the filters being efficient is Brownian motion (the chaotic motion of free particles in space). However, by the same token, Browning motion by the very virtue of its randomness, can be brought against Claim 3. arguing that probably the most of particles twice as small as the mask pore will get through.

It is important to notice that Claim 3., as stated on http://wikipedia.org, comes with a disclaimer, quote: “That statement does not derive from given reference [10]”.

7. Claim 4. must go with a provable demonstration of the ‘COVID-19’ virus’ ‘travelling’ patterns, how many will travel by themselves and how many in droplets, all with experimental data open to public scrutiny, review and researches available to support their findings.

8. The vast majority of the masks worn aren’t NIOSH N95 or N99 compliant. Their pore sizes vary from 0.5 to 10 µm for the “surgical masks” and upwards of that for all other “face coverings”.

What is your reason for wearing a mask?
