I just ordered an Enerzen O3 generator for the house. $85. My wife was complaining about the pet smells anyway!
I ordered some more N95 masks to supplement my supply from two years ago (wildfires).
Heh - that ozone generator that I ordered. I cancelled it. Sounds like it won’t do much to a virus in the house. Plus there are side effects from some chemicals that it will break down.
THEN I read your article - they were doing fancy medical stuff with 03. The article I was reading said it works well in water (and bodily fluids I guess?) - but not so well in air.
Sounds like my large 3M room air HEPA filter is probably better anyway.
