Everyone knows that the coronavirus is transmitted in droplets expelled by coughing and sneezing. The droplets can quickly spread up to 6 feet and more. Indeed, the Fluid Dynamics of Disease Transmission Lab at MIT concluded that, “given various combinations of an individual patients’ physiology and environmental conditions, such as humidity and temperature, the gas cloud and its payload of pathogen-bearing droplets of all sizes can travel 23 to 27 feet (7-8 m).” Furthermore, viruses can remain suspended in the air for hours.
That’s why we are keeping physical distance and wearing masks outdoors. The transmission can come from someone who is asymptomatic and totally unaware of being infected. This means we should use extreme caution, even within families staying at home in isolation, where air circulation is confined compared with the outdoors. Pandemic experts advise that the safest course is to behave as if everyone is infected.
Unfortunately, while coughing and sneezing help the virus travel farther, even talking is likely to transmit the virus. A May 2020 study used lasers to make it possible to see, and videotape, the results of talking. The study concluded that, “normal speaking causes airborne virus transmission in confined environments.”
Here is where the technology of a high-density negative air ionizer may offer significant protection. It places an imperceptible charge on the gas cloud, or aerosol, including relatively large particles (like dust), smaller particles like bacteria and mold spores, and even tiny virus particles measuring as little as 0.052-0.140 micrometers. The charged particles fall to the floor, or are attracted to surfaces of grounded electronic devices (like computer screens), which can be wiped away during normal housecleaning. Subjectively, the air becomes more breathable and refreshing – and less hazardous to health….
