I sell Nikken Water Filters because, after a lot of research, I believe they are the best on the market and the best value for money too.

Depending on the water supply and pipes, tap water can contain traces of many chemicals, including chlorine, disinfectant by-products, sediments, heavy metals, and pesticides. Nikken PiMag water products have been developed to transform your normal tap water into clean PiMag water.


The first stage of the PiMag Waterfall Gravity System is a pre-filter, removing larger particles from the water. The second stage is where the water passes through activated carbon to capture microscopic particles. The final stages include a mineralisation process as the water flows through a layer of Pi Minerals; these minerals increase the pH of the water, making it alkaline, and decrease the ORP (Oxidation Reduction Potential). An ionizing effect further reduces potential oxidation by providing ions to neutralize free radicals. The water then flows over a bed of mineral stones, ending in a powerful magnetic energising and conditioning process.


A unique feature of PiMag® Water Technology is the addition of pi minerals to the process. Pi water was originally discovered by Japanese scientists in the 1970s. Observation had suggested that the water from an isolated hillside stream had a remarkable effect on the plant life in the area.The scientists examined the environment and found that it contained an unusual collection of topographical features. The surrounding hills contained magnetite and calcium. The watercourse flowed over silicates, the material that forms natural crystal. The water from it was found to have an atypical combination of minerals, and was naturally alkaline. This alkalinity helps to balance the acidic diet and stress-induced acidity that is commonly experienced in modern life.Duplicating these conditions in the laboratory resulted in a form of this “pi water.” Magnetic technology was added, as a magnetic field assists in conditioning water without adding salt or other chemicals.
