Ultraviolet light can kill almost all the viruses in a room. Why isn’t it everywhere?::Can special lightbulbs end the next pandemic before it starts?

      Joke aside, looks like they’re using a higher bandwidth of light, 222nm compared to more common 254nm uv for medical uses. It doesn’t penetrate the skin or eyes sufficiently to cause damage.

      And bleaching all materials in the room. And slowly destroying anything made of paper or plastic or wood.

      What if, and hear me out,

      What if…

      What if… we just ran them when people weren’t in the room? 🤯

      Crazy what happens when you can come up with your own thoughts instead of parroting reddit comments ad nauseam.

        This is already a thing in many hospitals, and has been used extensively even before covid.

          And there are also UV systems that can be added to air ducts to kill off airborne pathogens as well. But they’re not cheap and not commonly used outside of medical facilities.

        Won’t work in spaces where people are around all day, like offices, but it doesn’t matter. The eye and skin dangers are already addressed for the most part. The major remaing question is ozone and the VOCs it combines with.

        Ozone is a concern (it’s bad to breathe it), as is using it as a cheap way to do less proper ventilation

        It also wouldn’t do much for things like COVID, where ventilation does help

        Lemmy users don’t respond well to reasonable criticism or facts.

        Only toxic and stupid comments allowed.
