When NBC News need expert advice they go to Allergy Standard CEO Dr. John McKeon. In this article, John explains the the different technologies that may be used in air purifiers, and how and why noise is created when they are running.
“Air purifiers, which are often labeled interchangeably with air filters and air cleaners, help remove indoor air pollution in a number of ways. Some trap and collect dirt and particulate in a filter, using a fan to draw pollution in. Other models use ultraviolet light sterilization or electrostatic filters to kill mold and bacteria”, said McKeon.
CERTIFIED asthma & allergy friendly® Dyson air purifiers feature strongly in the NBC News best list. Allergy Standards CERTIFIES air purifiers asthma & allergy friendly® through their Certification Program run in collaboration with the Asthma and Allergy Foundation of America. Certification is only awarded if the product passes stringent scientific testing so consumers can trust they are buying a better product. In the case of air cleaners, the product is tested in an environmentally-controlled chamber, using test dust that contains allergens. It is important that the air cleaner can remove allergens from the air, and that these are captured in the filter of the air cleaner. Different allergens act differently in the air, because they have different sizes and features.
The air cleaner standard is one of 46 standards in the asthma & allergy friendly® Certification Program, covering appliances, bedding products, air filters, building products, and services that can have an impact on the indoor air environment.
