Odor Killer originated as a natural odor control product for industrial use. In use on the toughest industrial odor environment, it proved its capabilities over and over in the field and in laboratory tests. Now the industrial strength Odor Killer is available for home use. Odor Killer safely eliminates smoke, food, sanitation, and biological odors in even the most confined areas. It is not a masking agent and does not operate in the same way as less efficient counteractants. Odor Killer creates a neutral atmosphere where objectionable odors are removed without any replacement odors.
