As America's favorite brand of reverse osmosis systems, and backed by iSpring's industry-leading customer support, the RCC7 is unequaled in quality, performance, and durability. The system consists of 5-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 greater 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. The system is quiet and low maintenance. Replacement filters are standard sized and sold at factory direct pricing. 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.

      Piece of Mind
      We installed the system ourselves. Watching Youtube videos 10 times helped a lot. It is a very impressive system that we trust 100% that it will produce healthy water for us. It didn’t seem important at the time when we choose this filter system but the water taste amazingly fresh. Highly recommend to others.

        Easy install.
        We needed a new r/o system and decided on the five stage ispring unit. The quality of products was excellent but I was most impressed with the installation instructions. All the hoses were color coded, you had written instructions and step by step instructions on YouTube. I appreciate the email from Sean offering to help if I needed anything. I am very pleased and would recommend this brand to anyone needing a r/o unit.

          Great customer service
          I purchased this to replace a pelican ro system. Water tastes super smooth and smellls better than what was coming out of the pelican system that we had just replaced the filters on 3 months ago. When installed there was a leak coming from the tank valve where the tube goes in. Richard at ispring responded quickly and sent me out a replacement valve that same day. New tank valve does not leak so overall a great experience.

            Great Tasting Water
            The taste is simply amazing, and it helps save the environment from all the plastic bottles we would have been buying, and throwing out.

            Best Product I've Ever Purchased!
            I don't know where to start. From the moment I opened the box I could tell this is a quality product. Everything was packed in good strong boxes. Everything was packaged neatly in plastic bags. The instructions were written in english by someone who's first language was english! Everything was so very clear in the instructions and I could have installed it if it were the very first DIY project I ever did. It even referenced a YouTube video that I could view to assist in the installation, which was very helpful. The guy in the video had the hairiest arms I've ever seen, but he was very informative! They went so far to include the tool to tighten the cartridges, and even included a little package of selected spare parts! Who does that!! If I had to find something on the negative side, it would be that they did not include a small amount of teflon tape that is needed during installation. I think this is one of the best products I've ever bought. I'm not kidding. This company has gone the extra mile to assure that you will get years and years of good, clean RO water. I'm so glad I made this purchase. THANK YOU iSpring!

              Modified to deal with pfas and pfos
              Install the system with the modification of adding a deionization filter. We have pfos and pfas in our water supply from Gen X and after much research determine this was the best solution. Ispring was very helpful in making this modification. The Deionization filter was purchased from another source.

                The iSpring filter system is a good long-term investment!
                When my wife and I moved to Tucson from Taiwan, as strangers here we decided to rent for two years while we became acquainted with our new location. Reverse Osmosis water systems are made available to the public in Taiwan and are found in many places around Taipei. Hospitals allow anyone to walk in off the street and fill their drinking bottles. We decided we wanted an under-sink unit, chose iSpring and bought it at Home-Depot. Our first surprise was finding that the apartment owner kept the water pressure abnormally low to save water. It was too low for the system we bought so we contacted iSpring and they sold us an upgrade with a pump to compensate for the low water pressure. We used the system for almost two years. During that time we purchased a single home and moved. One thing I insisted on taking was the iSpring R-O water system. In our new home, we encountered an unexpected problem; the kitchen counter top is almost 2" thick and that is right on the edge of being too thick for our faucet. Richard, our contact in iSpring sales was generously helpful as always. Here in Tucson, we found Water-Tec, an iSrping competitor who helped us with an extension tube for our faucet. Richard also provided us with a Refrigerator Ice Maker Kit and with all the pieces in place, we installed the system in our new home. We are so pleased to have our delicious R-O filtered water once again. It's taken us two months but it was worth the wait.
