We supply a great range of ozone generators that kill bacteria and viruses, including coronavirus, and eradicate unpleasant smells. They require no refills and are environmentally friendly. Based in the UK. What can Ozone do for me? Ozone helps reduce the risk of bacterial and viral transmission, it also kills mould and mildew spores and can prevent some pesky insects from hatching. Ozone doesn't just remove bad or unwanted smells, it eradicates them at the source. Ozone produces no sickly sweet chemical smell you get from air fresheners, instead cleans the air, making it smell fresh.
