Abstract

A method for decontaminating air in an ice making machine, comprising: controlling the level of ozone outputted from an ozone generator by modulating the voltage using pulse width modulation; and contacting the air with the ozone. Preferably, the level of ozone is about less than 0.1 ppm. The pulse width modulation controls the level of the ozone by controlling or manipulating the grams per hour of ozone introduced from the ozone generator into the ice making machine.
