#427 Can semiconductor clean-rooms provide SARS-Cov-2-free environment?

When not interacting with the living cells aren’t the viruses behaving like independent particles? Aren’t then class sub-1 clean-rooms used in cutting edge semiconductor manufacturing creating a virus-free environment? At least SARS-Cov-2-free environment?


The size of the SARS-Cov-2 virus which is causing coronavirus disease wreaking incredible havoc around the world these days is apparently in the range of 120 nm while the advanced ULPA (Ultra Low Particulate Air) filters are removing from the air particles as small as 100 nm. Besides, air in the clean-rooms is continuously exchanged and ULPA filtered which further limits any potentially harmful interactions with viruses.


People working in semiconductor clean-room are wearing elaborate gowns to protect environment against particle generating people, no other way around. In the case of clean-rooms used for virus protection such a costly  gear wouldn’t be needed.


All in all, I think there is good chance clean-room technology will be spreading in the future well beyond semiconductor labs and fabs.
