An ozone generator is a device that uses ozone to cleanse the air of odors, kill mold, bacteria, and even viruses. The generator exploits the reactivity of ozone (O3), which possesses one extra oxygen (O2) atom compared to naturally occurring oxygen. Ozone is highly reactive when attaching itself to other molecules in the atmosphere. It gives away it's extra oxygen molecule, which then reacts with odor-causing pollutants, neutralizing them.\r
