      This can be sometimes rather technical, but there are some good methods of sterilizing that are easy to do, as well as how to convert various alcohol percentages to the best percent-range (according to Tech Ingredients, it’s from 70-75%).

      One of the comments also says that you can get much of the alcohol out of a lower-percent type by just adding a lot of salt to it. I don’t know amounts, so maybe the chemists around here can detail that trick 🙂

      Leave the ozonolysis to chemists who want to oxidize olefins to carbonyl compounds.  Just plain soap and water kills viruses; virus coat proteins can’t stand up to very much at all.   If it makes you feel better to put some bleach in the water to give it a fresh smell, by all means go for it.

        Plus, he explained the use of the UV-tube to sterilize rooms, not just masks. He seemed to defeat the making of such devices due to the power-supply issues with such lamps (such as fluorescent).

        What I was talking about with the salt and alcohol was from a comment on the video at YT. If you go to it, you’ll see. They just do not give an amount of how much salt it takes to how much rubbing alcohol (a ratio would be nice).
