SEM Activator (SEM) has a unique Triple Spiral Chamber and Ceramic Ball layer structure that allows water to activate and purify standard tap water and groundwater. The triple spiral chamber helps create a centrifugal force, causing the water to pull away from the center axis and undergo a redox (oxidation-reduction) reaction. When redox reaction occurs, one component loses electrons or is oxidized and another gains electrons or is reduced; that is, the redox reaction eliminates the red rust and alleviates the hardness source cation (positive ion). Ceramic balls nestled in the SEM replicate the natural bed rock formation, enabling the SEM to produce optimal water filtration. These ceramic balls generate. Far Infrared Ray (FIR), increase surface activity, serve as a catalysts, and have strong disinfection properties.
