Our Certification has been around for over 12 years and is used worldwide to signify that products have met our standard criteria. The strength of our program relies on best-in-class test methods and assurance that each product has been evaluated for efficacy and impact on asthma, allergies, and the home environment before permitting usage of the Certification Mark, as opposed to relying on manufacturer’s data or testing reports (which can often be inaccurately reported or tested in facilities that are not properly vetted).
