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

I’ve had the six stage model RCC7P – AK for about a year. I’m just now doing my first filter change, all, but the RO Membrane. I have a bit of an unconventional installation. My system is about 20 feet from the water supply in the sink drain. I’ve had it installed on the floor. But for this filter change, I mounted it to the wall about 12 inches above the floor with support under the filters. That will make future filter changes much easier in the future. Couldn’t be happier with the system. Great system, great tasting water with very effective filtering. My water starts off with a TDS of about 500, water are coming out of the filtered faucet comes in at under 40 TDS :-). Curious One. Mesquite, NV. Wed Feb 04 2026

iSpring RO500-BN, NSF Certified Tankless RO Reverse Osmosis Water Filtration System, 500 GPD Fast Flow

Had the hire a plumber to install this. Very quick and easy, except for making a new hole for the dispenser to be mounted. Water comes out quickly and the taste is amazing. You can easily tell the difference! I’m excited to have this and hope it lasts for many years to come! Highly recommend!. Karen. Woburn, MA. Sat Jan 01 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
