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.
