iSpring RCC7AK 6-Stage High-Capacity Under Sink Reverse Osmosis System

Certified to NSF/ANSI 58, the RCC7AK is a multi-layered filter system that provides optimal protection against over 1,000 different types of contaminants, including arsenic, asbestos, chlorine, hormones, fluoride, lead, mercury, sodium, and more. Featuring some of the longest-lasting filters in the industry, the system consists of 6 stages, each one designed to progressively remove contaminants and improve water quality. After flowing through the initial 5 stages of the iSpring RCC7 line of reverse osmosis filtering products, the RCC7AK model adds another alkaline remineralization (AK) stage.

This stage is designed to restore the natural alkalinity and mineral balance of the water. The RO process effectively generates pure water but it also removes a few helpful minerals in the process. The red mineral stone portion of the AK filter adds back healthy minerals including not just calcium, but also other beneficial minerals, like magnesium, that other systems don’t.

The calcite portion of the filter neutralizes the pH of the RO water. And the water tastes better too. Because RO water is so pure, some people may find it tastes unnatural.

Many people prefer the more natural taste that comes from the presence of some minerals in the water. Remineralization restores just the right proportion of healthy minerals.
