iSpring RCC7AK 6-Stage Under-Sink Reverse Osmosis Drinking Water Filtration System with Alkaline Remineralization Filter

Reverse osmosis is undoubtedly the best in-home water filtration method, but it is important to remember the RO process also removes many good minerals from your water in addition to the bad stuff.

After the reverse osmosis process and before the faucet, the RO water passes through the alkaline re-mineralization filter. The alkaline filter is made up of two sections - half red mineral stone and half calcite. This allows the filter to achieve two specific purposes.

The red mineral stone adds back healthy minerals that were removed during the reverse osmosis process, such as ionized calcium, magnesium, sodium, and potassium. In doing so, it improves the taste of the RO water as well.

The calcite portion of the filter neutralizes the pH, as the water is generally on the acidic side after the RO process. When the RO water comes in contact with the naturally occurring calcite material, the acidity of the RO water dissolves the calcium carbonate, neutralizing the pH.

The end result is bottled quality mineral water, right from the tap. In addition to the cost savings and health benefits, widespread use of in home filtration systems would reduce the impact of plastic bottles on the environment tremendously. With all of the benefits, it only makes sense to go RO!
