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).
Oxygen Concentrators are often referred to as oxygen machines, oxygen generators, or O2 concentrators. They provide a cost-effective way for oxygen therapy patients to supplement their oxygen needs without the need of bulky, heavy oxygen tanks. Unlike tanks, concentrators do not run out of oxygen.
Ozone is the fastest acting oxidizing disinfectant and the most efficient broad spectrum micro biological control agent commercially available. Being highly reactive and completely non-discriminating it immediately starts oxidizing anything it comes in contact with air.?
