Air treating apparatus and method therefor

摘要

An air treating apparatus and method therefor is disclosed that can be used in spaces occupied by humans or other mammals for deodorizing the air with ozone while the humans or other mammals are present. A housing having an air inlet and an air outlet defining an air flow passageway therebetween has a fan in the inlet for drawing air through the passageway and discharging the air through the outlet. The housing contains a transformer for supplying high voltage electrical power to an ozone generator in the air passageway for enriching the air in ozone and discharging a mixture of ozone in the air at a predetermined concentration. A potentiometer controls a timer for controlling the interval over which ozone is produced in an "on/off" manner. The time averaged concentration of ozone thereby is controlled so that exposure to ozone does not exceed established limits over time.
