RKIN water filters for drinking water are based on powerful reverse osmosis technology. The best possible water purity combined with the lowest cost per gallon of purified water make our products an obvious choice for environmentally conscious consumers.

OnliPure™ The specialty Ion Exchange Media inside our OnliPure Post Filter reduces any leftover contaminants after the Reverse Osmosis process to zero TDS. Measure and confirm from your home with a simple TDS meter.

AlcaPure™ Polishing Alkaline Post Filter returns beneficial minerals – Calcium and Magnesium to purified water for the best taste. It also increases the alkalinity of the water to a perfectly balanced level of 7-8 pH.
