As America's favorite brand of reverse osmosis systems, and backed by iSpring’s industry-leading customer support, the RCC7AK is unequaled in quality, performance, and durability. The system consists of 6-stage, layered filtration built around precision reverse osmosis (RO) technology that removes over 1000 different kinds of contaminants in order to provide the best home drinking water filtration available. Unlike some other systems, the combination of both GAC and CTO filters in the 2nd and 3rd stages provides extra layers of protection against harmful chemicals than CTO alone. It features a 75 gallon-per-day capacity RO membrane, which is larger than most in its class and provides the capacity to economically handle the drinking water needs of even a large family.

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.

Designed for do-it-yourself installation by most users, the entire system fits nicely under a standard kitchen sink. Installation is straightforward and all parts necessary for installation are included. You are guided by clear, well organized written instructions, instructional videos and access to iSpring’s unparalleled technical support. The system is quiet and low maintenance with no moving parts. Replacement filters are standard sized and sold at factory direct pricing. A lead-free, solid brass faucet with brushed nickel finish is included with the system and is usually mounted on the counter as the primary source of drinking water, but output lines can also be connected to your ice maker, coffee maker, etc. The whole system is backed by a 1-year money-back guarantee, a 1-year manufacturer warranty and iSpring's unique lifetime technical support provided right here in the USA in Alpharetta Georgia. With the iSpring RCC7AK, enjoy crisp-tasting, bottled quality water, every day, right in your home.
