Ozone concentrator

A method for preventing microorganism multiplication, including using 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 the ozone and ions. The generation of ozone is suppressed by reducing the discharge current in the ionization chamber using a pulse converter, which is provided to control the current flowing at the time of discharge, when generating the ions and ozone in the ionization chamber. Ions are produced in the ionization chamber in a high concentration to produce and supply ionized gas containing a low concentration of ozone and a high concentration of ions, which prevents microorganism multiplication on the objects.
