The STETZERiZER filters will not actually do what is claimed for them. To do that they would need to be connected into the incoming power feed of the house, not just hung off a power point. IMHO the dirty electricity website: http://dirtyelectricity.com.au/healt...alth-benefits/ Has breached the Trade Practices Act with its claims about the "Health benefits" of the STETZERiZER filters.
