The Aulterra Whole House USB contains a proprietary blend of paramagnetic rare earth minerals that neutralize the negative effects of EMFs on the human body. The Aulterra powder in the Whole House USB puts out a subtle energy field that interacts with the AC electrical current in the house wiring which changes it from a coherent (chaotic) waveform to an incoherent (natural) waveform. The neutralization of these EMFs can greatly enhance the environment in which you work, play, and live with loved ones with no adverse side effects. Aulterra Neutralizers do not block, remove, or absorb EMF. That is one of the most unique features of how our products work and why they work so well. In fact, if you were to ‘block' or remove EMF then you are blocking or removing the frequency waves in which your wifi electronics rely and your electronics would not perform well, if at all. Aulterra's propriety blend of highly paramagnetic earth minerals emit a strong incoherent frequency that ‘neutralizes' the coherent manmade EMFs emitting from electronics, wireless devices and WiFi signals, etc., making them no longer harmful to biological systems.
