Ozone Generator
An ozone generator is a device designed to produce the gas ozone. Ozone is used effectively in water purification, but ozone in the air must reach high levels to remove air pollutants. Ozone also masks the odour of some pollutants by impairing a person's sense of smell. Ozone generators also referred to as ozone machines, are ozone-generating devices that intentionally produce ozone gas. When sold as air purifiers to be used in indoor occupied spaces, they are marketed to be safe and effective (though these claims are generally false).
