device and method to prevent the spread of germs

摘要

By use of a gas containing a low concentration of ozone and a high concentration of ions, so that the multiplication of microorganisms can be safely and fully prevented by an additive effect of ozone and ions. While the generation of ozone is suppressed by suppressing the discharge current with a pulse converter 23 being provided for controlling the current flowing at the time of discharge to be made for the generation of ions and ozone in the ionization chamber, ions are produced in a high concentration to produce and supply ionized gas 10 containing a low concentration of ozone and a high concentration of ions to objects 14.
