Negative ions to reduce the airborne transmission of Covid-19

This idea concerns Covid-19. Since the Covid-19 campaign no longer exists here, I have no recourse but to post this idea, and many others, in the five current campaigns which still exist here.

It appears that DHS no longer reviews ideas that are submitted on this site. I hope they will disprove this assumption by communicating with me on each of my ideas and directly address any potential which they may have.

My idea follows.

The following concept, involving the use of negative ions (created by negative ion generators), has the potential to greatly limit the airborne transmission of Covid-19 in health care facilities, indoor work settings of all types, waiting areas, public modes of transportation, etc.

In a nutshell, the negative ions weigh down any particulates in the air (including microorganisms) and cause them to fall to the ground. Furthermore, there is research which indicates that negative ions can kill viruses outright. If the negative ions from negative ion generators can indeed have these effects, they have great potential for limiting the exposure of people in buildings to any airborne Covid-19 in the area. It is the indoor environment where the threat from airborne transmission is the highest, as Covid-19 does not do well in sunlight or in hot temperatures.

Negative ion generators have been in existence for many years and manufacturers have made various improvements to them. They have been mentioned very sparsely during the Covid-19 pandemic, despite the reported benefits. Despite their negligible use, to date, there is sufficient research available to suggest that active consideration of them as a viable weapon against Covid-19 is merited. If a respected entity concludes that these devices could indeed be a significant contribution in the fight against Covid-19, I would envision that high capacity units that do not emit ozone could be installed in the settings as mentioned above. It may not be feasible to place devices in every room of various buildings, but at least hallways and public areas should be considered. Studies could be performed which look at the infection rate at health care facilities with the devices and those without the devices.

All we need at this stage is for someone to confirm whether or not the overall concept has merit and, if so, initiate efforts for mass production and distribution. If this were to take place, all types of health care settings, work settings and entertainment/dining settings would be much safer for the people who work there. They would also increase public confidence in the safety of such settings and, in turn, increase public patronage at such sites. And that will be a tremendous boost to the economy.
