The Atmosphere air purifier brand is made by Access Business Group, which is owned by Alticor. Alticor is also the parent company of Amway and Quixtar, so the Atmosphere products are only sold through these distribution channels.
The Air Purifier Guide website notes that Access Business Group operates 10 US manufacturing facilities around the country that make Atmosphere purifiers. The Atmosphere air purifier was designated asthma and allergy friendly in 2009 by the Asthma and Allergy Foundation of America. After the purifiers are manufactured, they are sold through Amway's direct sales channels, which are part of their multi-level marketing business setup.
