Feel confident with every sip that you are providing the best quality water for you and your family. The KOHLER® Aquifer reverse osmosis (RO) water filtration system effectively reduces contaminants including arsenic, fluoride, TDS, bacteria, virus, lead, mercury, chlorine, and pharmaceuticals in your cold water. Install your Aquifer reverse osmosis filtration system with a KOHLER® beverage faucet.

Replaced my Culligan system with this and am very happy with the change. Had my plumber install it with new Kohler faucets in a kitchen remodeling project and it works great. I added a separate bar faucet that matched my sink faucet - which is also on a different Kohler filtration system. Filters are easy to order and replace every 6 months. Overall, very pleased and way cheaper than other solutions.. Anonymous. Fridley, MN. Wed Oct 22 2025

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. Tue Nov 22 2022

I could still taste the chlorine in my tap water, even after I put it through a jug filter. Now it is as good as any bottled water. It comes out quicker than I expected. I love my new water filter and it doesn’t take up room in my fridge.. Peggy. MA. Fri Jun 28 2024
