Chem-Dry decided to not only test allergen removal from carpets, but also allergen removal from upholstery and our ability to remove bacteria from the home. The study was conducted in a cross-section of consumer homes in the U.S. and abroad, using the HCE process along with a pre-spray.
Here are the results from the final report:
We remove an average of 98.1% of common household allergens from carpets and upholstery (combined). The common household allergens we tested were cat dander, dog dander and dust mite allergen. This broke down further into the respective service lines as follows:
o We remove an average of 97.4% of allergens from carpets
o We remove an average of 99.1% of allergens from upholstery
· We remove an average of 89.0% of the airborne bacteria in the home, showing that we have a significant impact on improving indoor air quality. This test incorporated the addition of a sanitizer to the cleaning process.
