*Based on results of studies conducted by independent laboratories of the Chem-Dry HCE (Hot Carbonating Extraction) and P.U.R.T. (Pet Urine Removal Treatment). Allergens tested were dog and cat dander and dust mite matter. Pet odor results based on testing with the most common odor sources found in dog and cat urine. Figures are an average across multiple tests.

**In independent laboratory studies, the Chem-Dry HCE cleaning process reduces surface non-living allergen matter from cats, dogs, and human dust mites when measured from pre clean to 24 hours post clean and airborne non-living allergen matter from cats and dogs when measured from pre clean to 24 hours post clean.
