Using the same technology found in casinos and five-star hotels, this is the most effective home odor-eliminating device available. The device automatically releases an invisible, dry mist of odor-eliminating microdroplets that are 100 times smaller and 1,000,000 times lighter than aerosol mist droplets. Unlike aerosol or plug-in sprays that quickly fall to the floor, the lightweight microdroplets remain airborne for up to 14 hours and drift to all corners of a room, eliminating unpleasant odors produced by tobacco smoke, cooked food, or any foul smell and replaces it with a pleasant, subtle scent. The device covers up to 10,000' Cu. (the equivalent of a 35' x 35' space with 8' ceilings), neutralizing bad smells in two or three adjacent rooms. About the size of a box of tissues, the device sets up unobtrusively on a table. Includes one fragrance cartridge that lasts up to 60 days; specify Lavender-Herb, Citrus-Mint, or Pine. Plugs into AC. 5 1/2" W x 5 1/4" D x 5 1/2" H. (2 3/4 lbs.)
