Certified to NSF/ANSI 58, the RCC7AK water filter is a multi-layered reverse osmosis system under a sink that provides optimal protection against over 1,000 different types of contaminants, removing up to 99% of rust, sediment, taste, arsenic, asbestos, chlorine, hormones, fluoride, lead (up to 98%), mercury, sodium, and more. Featuring some of the longest-lasting filters in the industry, the reverse osmosis water filtration system consists of 6 stages of water filters, 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 RO system adds another alkaline remineralization (AK) stage. This stage is designed to restore the natural alkalinity and mineral balance of the water. The RO membrane effectively generates pure water but also removes a few helpful minerals. The red mineral stone portion of the AK water filter adds back healthy minerals including calcium, and 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. Remineralization restores just the right proportion of healthy minerals.

I installed this yesterday and woke up to great coffee due to using this water. The difference in taste is amazing and best of all, no more plastic bottles. I fill up glass jars and keep in the fridge. I only wish I had bought this years ago.. Bobby. US. Mon Nov 21 2022

The RCC7P-AK 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. It features a 75 GPD 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. The RCC7P-AK model is equipped with a booster pump for situations where inlet/house water pressure is low – below about 40 psi. After flowing through the initial 5 stages of the ISPRING RCC7 line of Reverse Osmosis filtering products, the RCC7P-AK also 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 also removes a few helpful minerals in the process. The red mineral stone of the AK filter adds back healthy minerals including calcium and 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.

excellent item, easy to follow instructions for install, and the water tastes great-pleased with my purchase, fair price. Gkl. Colorado. Thu Feb 05 2026

I am very disappointed with the lack of information on replacing the filters on the ro ispring tankless 800 gpd. there is not one video anywhere that shows a step by step video of how to. The actual system has been great until my first filter replacement. I would never have bought this product had I know there was zero information available on this topic.. T. Mon Aug 26 2024
