IIRC, they have UV sterilizers for central HVAC systems. So while it may not sterilize surfaces, it will kill all airborne pathogens.

A bit of the old Ultraviolence, eh?

Not necessarily agreeing with the article posted, but for all the people who clearly didn't read the article:

That's just one paper I found searching for far-UV. Seems to be many more.

Again not saying it's 100 % safe or anything, but it looks promising.

An actually halfway decent idea might be adding a strong UV light inside the washing machine or dryer to kill germs. Modern eco methords with 30-40 C° just dont kill the germs effectively. You'd need to wash your clothes at last at 60C° which most clothes (especially sports wear) cant handle anymore. Or just dry them on the outside where we also have a Strong UV source aka. The sun.

In Macau, they have little trash garages which are flooded with UV at night

The bulbs don't last very long last time I looked into this for home use

I always thought these were pretty cool. I'm not sure how HEV compares to UV though, or if it even works

UV light kills almost all viruses because it's ionizing EM radiation. So it also fucks humans up, xd. I mean just stay on sunlight naked for a day. Your body will be so happy. All the mutations from ionizing radiation would be great.

But yeah we life in a society where ppl is scared of Radiofrequency EM waves (non-ionizing), "dangerous cell phone towers, wifi dangerous". That same people recomends staying long periods of time with direct sunlight contact without protection (yeah we need protection because sunlight spectrum has UV and higher freq ionizing radiation).

Sunlight healthy/radio waves dangerous, that is the most stupid statement ever.

Sunlight is beneficial in small dosis because of how we syntetise vitamins (as little as i know). But remeber if you are scared of microwaves, remeber that sunlight has much more higher freq(higher energy) waves.

That’s how you get UV resistant strains of all kinds of microbes

This is the best summary I could come up with:

Ultraviolet retained a small coterie of enthusiasts over the ensuing decades, focused narrowly on preventing transmission of tuberculosis — which has no reliably effective vaccine for adults — in its remaining hotbeds, like homeless shelters.

The biggest test it received, the Tuberculosis Ultraviolet Shelter Study of 1997-2004, demonstrated that “upper room” UV, in which UV-emitting lamps are placed at least 6.9 feet above the floor where they can disinfect air without harming humans, was safe.

It wasn’t — detective work from scholars including Linsey Marr, Jose-Luis Jimenez, and Katherine Randall in the middle of the pandemic determined that this conclusion was based on a misinterpretation of the Wellses’ research that had somehow persisted for decades in the medical profession.

“This is the most difficult talk I’ve had to give in my career,” Jose-Luis Jimenez, a distinguished professor of chemistry at the University of Colorado, told the audience at the first International Congress on Far-UVC Science and Technology this past June.

But 2020 was also an unusually brutal year for airborne disease: 49,783 Americans died from influenza in 2019, for instance (and none from Covid); 1 percent of that number is about 500 people, which starts to feel comparable to the air pollution cost Jimenez identifies.

Jimenez favors using UV in very high-risk locations, such as hospitals, but worries that construction companies, schools, malls, and the like will seize on the potential of far-UV as an excuse not to invest in proper ventilation and filtration, leaving us with the ugly trade-off he identifies.
