Ideal for rooms up to 3000 cubic feet. You can breathe easy while the Uvonair attacks and neutralizes odours at the source. Uvonair eliminates odors caused by tobacco smoke, plants, moulds and mildew. It tackles the unpleasant odors from pets, cooking and damp basements. The Uvonair generates Ozone (O3) - one of the most powerful oxidizers available. O3 doesn't just mask odours like mere air fresheners, it neutralizes odours at the source, then harmlessly converts to CO2 and oxygen. Cheaper to run than a 100w light bulb.
