It is produced using electro-controlled technology and pure water from a 9-stage water purification process, to achieve a very small particle size (0.0006 to 0.005 microns). This small particle size is important because it provides a much greater surface area and therefore more of an effective liquid. The 15ml refillable size is ideal for carrying in a bag or pocket.
