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 Gal. 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.

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.

Excellent RO system for home
Two years ago, my uncle get tired of buying bottle. So I brought him an ispring 5-stage reverse osmosis system and installed it in his house. I found that RO unit was very easy to install. I also discovered that system was very well built with quality materials and good workmanship. Then I brought an exact system to replace the existing RO system in my house. I am a mechanical engineer and have over 30 years of experience using different RO systems. I can tell this is the best built RO system that I have seen based on ease of installation, materials quality, engineering design and workmanship, and price. Then I brought a third ispring RO system as a gift for my sister and installed it for her as well. She and her family have been using it for over a year now and they just love it! My niece has just brought a new house in Santa Rosa, CA and I already told her that I will give her a new ispring RO system as a house warming gift and will install it too when the COVID19 lockdown is over. The bottom line: I have personally installed 3 ispring RO systems and used in my own house and others for over two years without any problems. Therefore, I strongly recommend using ispring reverse osmosis system to get clean and safe water for you and your family.

5 stage reverse osmosis system

by Bryan
Convenient and affordable
Installation process was easy and straight forward with clear instructions. Customer service agent Richard was very helpful as he helped me identified a faulty part and sent me a new one in the mail. I am happy with my purchase and water quality meets my expectations.
by eastweiming
Great system, fast response to customer service.
Our water smells like rotten eggs, our town is known for bad water quality. Before buying this product i contacted a plumbing company tot talk about our water. They warned us that even if a system was put in that our water could still retain the smell. So instead of an expensive experiment we tried something affordable. We were impressed immediately and use this system constantly. Instead of buying water in 10L jugs we now have a hose rigged to fill the bottles to use with our water dispenser. NO SMELL. We had a problem with our system constantly draining not more than 3 days ago. I contacted Don at their customer service department. He asked for our personal information and sent a part out immediately. Great customer service thanks Don. Great system, fast response to customer service.
by Clean Water
Great Product
The system is affordable and very simple to install and maintain. 75 GPD was plenty for my family and the unit fits well under my sink. Great Product! Neat clear cap for the sediment filter too.
