Carpet Washers that are certified Asthma & Allergy Friendly® are tested according to the ASP:13-01/101 Carpet Washer Certification Standard. The certification process uses an algorithm of proprietary and recognized scientific techniques to assess carpet washers for their ability to reduce allergenic and irritant materials. Product samples that pass certification testing are granted a certificate stating that the particular carpet washer meets the requirements for the Asthma & Allergy Friendly® ASP:13-01/101 Certification Standard.
Allergy Standards Limited subjects carpet washers to allergen and particle count performance testing to ensure that the carpet reduces total allergen burden without significantly contributing to an increase in airborne allergen levels.
The Asthma & Allergy Friendly® certification mark is awarded to those carpet washer products that have been scientifically demonstrated to contribute to the goal of allergen reduction.
The carpet washer standard includes:
- Evaluation of the capability of the carpet washer to remove allergen-containing test dust from soiled carpets
- Evaluation of airborne allergen and particle levels during carpet washing
- Measurement of relative humidity levels in the room in which the carpet washer is operated
- Measurement of moisture levels in the carpet following washing of the carpet
All certified Asthma & Allergy Friendly® carpet washers carry a unique certification code.
