Virus particles come from people, like you and me, when we are ill, even before we are symptomatic. While the necessity for masks for this pandemic may be ending, barrier face coverings (BFC) may, in ...

Air filters are able to capture viruses, bacteria, and fungi, which can remain biologically active on them. Is it something to worry about? Details on CCJ.

The company says recent testing showed that it can remove 99.5% of particles as small as 0.003 microns (about 1/4 the size of the SARS-CoV-2 virus and influenza particles, so quite useful for cold ...

Viruses in droplets, which are larger than 100 microns, fall to the ground in seconds within about six feet of the source or spray onto people nearby, the letter states.

Viruses are roughly 100 times smaller than bacteria, and typically range from 0.004 to 0.1 microns in size. This means even the most powerful air filters would struggle to purge a virus from the air.

The newly discovered virus belongs to a class of giants discovered just a decade ago. Because of its size (1.5 microns in length), it can be seen under a microscope, unlike other types of viruses. (A ...

Air filters have been known to capture viruses and a lot of other nasty microscopic things so take special care when changing one out in the cab. That advice comes from leading air filtration ...

Researchers don’t know how many virus-laden particles people infected with COVID-19 might expel in the average droplet, including the micron-size droplets — called aerosols — that linger in ...

In fact, there is no neat and no meaningful cutoff point — at 5 microns or any other size — between droplets and aerosols: All are tiny specks of liquid, their size ranging along a spectrum ...

In 2013 "Pandora virusAlthough the largest size virus called "virus" has been discovered,Aix-Marseilles UniversityofJean-Michel ClaverieWith Mr.Chantal AbergelMr.'s research team took over 30,000 ...

The company says recent testing also showed a 99.9 percent reduction rate for viruses as small as 0.025 microns in size (about 1/4 the size of the SARS-CoV-2 virus and influenza particles, so ...
