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.

About This Product

Certified to NSF/ANSI 58, the RCC7AK water filter is a multi-layered reverse osmosis system under 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 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, 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.
