The Alkaline K SERIES-75PI is one of the best water purifying systems in the market that produces Natural Alkaline Calcium Ionized water. Unlike water ionizers, this system uses a special kind of filter built with natural stones to add Calcium, Magnesium, and Potassium to your water after cleaning the water up to 98% by a reverse osmosis membrane. Reverse Osmosis is a way of separating dissolved solids and organic matter from water by passing it through a special membrane. The membrane separates toxic chemicals and inorganic minerals and other impurities from the tap water. This system is capable of producing clean, refreshing ALKALINE IONIZED WATER up to 75 gallons per day (GPD). The water production depends on the feed water supply pressure, temperature and quality.
