iSpring RCC7-BLK, NSF/ANSI 58 Certified, 5-Stage Reverse Osmosis System, RO Water Filter System Under Sink, Drinking Water Filter, 75 GPD, Stylish Black RO Faucet

Outstanding support — Sean went above and beyond I inherited an iSpring RO system with my new home and it started leaking, with no manuals left behind. I called iSpring support and reached Sean, who diagnosed the issue over the phone and asked me to send photos. He quickly spotted that the system had been mislabeled and was missing components, and as a courtesy he shipped me a complete new machine head, housings, and a pressure regulator — free of charge, arriving within days. His instructions for transferring the membrane and filters were clear, the install went smoothly, and the system now runs leak-free. This is the kind of support that earns a customer for life. Thank you, Sean and iSpring! (Tip: the photos attached show the new setup.)

The RCC7 is an awesome home RO system. I am going on my eighth year with it and will buy it again if I ever need a replacement. The product is high quality, the instructions are clear and most of all, the service is unparalleled. I have dealt with Sean multiple times and will continue to ask for him by name. He is helpful, listens carefully and keeps his word. He promised to send me two parts, and three days later they were at my doorstep. With iSpring you are not just getting a quality product and support for the warranty period. You get lifetime help and people like Sean who care and go the extra mile to take care of you. I cannot recommend and commend iSpring products and personnel enough.

[This review was collected as part of a promotion.] Very happy with the RCC7. The water is safe to drink it eliminates so many harmful contaminants I feel safe drinking the water living on a barrier island. Sean help out so much and was very helpful. Thank you Sean

We had our iSpring system installed this week and we are very pleased so far. The water tastes great, the water pressure/flow rate is totally fine, the mini faucet looks nice and is such a helpful feature. Genuinely happy with this product after months of researching different systems. Few things to consider/know before purchasing: Despite the reviews I read, I had to hire a plumber to install the system. It was very complex and too much for me and my generally-handy father-in-law. Also, it takes up significant space under the counter. That's not a complaint, I had researched beforehand and knew what I was getting, but just helpful to know. Two thumbs up! Would recommend to anyone considering purchasing an RO system.

Big fan of ispring. Been using the same system for 8 years. Had a housing crack and Sean was a big help. Shipped my new part out asap.

Talked to Sean and he helped right away.

I have a stainless electric kettle that after one day of refrigerator filtered water had tons of deposits on the bottom and hence was cleaning it with vinegar once a week. This system is everything I expected. Finally there are no more deposits in my kettle and water tastes so much better. Highly recommend to those who like to drink tea or coffee!

I also purchased a digital water quality tester and verified that the newly filtered water was consistently testing at around 24 ppm (vs the 250 ppm from our unfiltered tap water). For now, the new system is working great, and making great tasting water.

It took about 3 hours to install, but this was because I had to go get a couple of connections and hose for our ice maker as I also purchased ICEK, the refrigerator kit, to get crystal clear ice cubes. The proof was in the taste of our morning coffee.
