Corona fear… and what we’re doing about it:

All hotel rooms in our house are treated with an ozone generator after departure. This effectively “disinfects” the air in the room! The ozone molecules attack the cell walls of bacteria, mold spores and viruses, so that these microorganisms are reliably rendered harmless.
During the oxidation process, the odor molecules “burn off” without leaving any residue. The only residual product after oxidation is natural oxygen.
