iTech Energy Water:

This special 3-layer spray filter bottle turns ordinary tap water into "energy water" to spray on the hair and skin for increased condition and softness. Passing tap water through this special carbon residue filter removes the hardening elements, exchanging them with hydrogen ions that soften the water. Passing through the ion exchange resin layer, the hardening elements in water are exchanged for hydrogen ions and changed into beauty soft water that's pH balanced at 3.5 to 5.0.

Finally, passing through the vitamin layer, the water picks up water-soluble Vitamin C. The result is pH-balanced water that is free of chlorine, heavy metals and other harmful elements.
