According to Amway, eSpring was the first water treatment system to receive certification for all fifteen NSF/ANSI 401 contaminants which include pharmaceuticals, pesticides and herbicides. The company also claims that, in addition to these 15 contaminants, eSpring is certified for more than 145 potential contaminants, including lead and mercury. eSpring was the first commercial product which employed Fulton Innovation's eCoupled wireless power induction technology.
