The Ultra High Purity Plus removes contaminants that are of concern to the consumer – such as chlorine, pesticides and heavy metals. The new fourth stage inline Alkaliser Filter provides enhanced water that is both energised and mineralised. This healthy inclusion to this system re-introduces minerals such as sodium, magnesium, calcium and potassium, raises the pH level (between 8 – 10pH) and lowers ORP (Oxidation Reduction Potential).
