The iSpring RCC7 provides a high quality and reliable under the sink treatment system. The system is WQA Gold Seal certified and provides 5-stages of filtration:
- 1st Stage: NSF Certified 5 micron high-capacity polypropylene sediment filters held in a transparent housing
- 2nd Stage: NSF Certified GAC Carbon Filter
- 3rd Stage: NSF Certified CTO Carbon Filter
- 4th Stage: NSF Certified High Rejection 75GPD TFC reverse osmosis membrane
- 5th Stage: NSF Certified Total Polishing Inline Carbon
The iSpring RCC7 can treat water at a rate of 75 gallons per day (GPD). The replacement filters removes up to 99 percent of over 1000 different contaminants including chlorine, fluoride, lead, arsenic, pesticides, pharmaceuticals, and fertilizers. The installation guide is provided along with, a 30-day money back guarantee and a 1-year satisfaction guarantee.
My iSpring RCC7 review also considered preventative features. While this high-quality system is well-sealed, a water detector is included, which detects leaks and can help prevent water damage in the event of a leak as the system ages. A water shut off valve regulates pressure between the water supply and the system itself, which helps minimize wasted water.
Standard with most under the sink RO systems, the iSpring RCC7 comes with a separate faucet. The faucet is designed to provide leak-free use over a 10 million use life cycle. Several styles of the faucet are available, including European-style brushed nickel faucet. Other features include a 360-degree swivel spout and non-air gap faucet.
One of the differences between iSpring RCC7 and some other systems is that the filter housing is transparent, allowing the user to see the filter media and determine when a filter needs to be replaced.
Pay attention to the differences between each iSpring TO system. For the review to be complete, we must mention that, as purchased, this system does not come with a remineralization 5th stage filter. This filter can be added to the system or a different iSpring model can be purchased that comes with remineralization. This detail is important because remineralization cartridges replenish the healthy minerals removed by the earlier treatment processes.
The manufacturer has made several recent upgrades to the system. It is now easier to install with a feed water adapter that connects to the cold water shut-off under the sink. Typically, the cold water shutoff is much easier to reach compared to the kitchen faucet stem, which makes installation much easier.
Overall, iSpring RCC7 provides a good value for homeowners looking for a high quality, reliable water treatment system. Before purchasing, I encourage you to read our reviews of other similar RO systems so that you can make an informed decision about the best system for your home.
If you have decided to purchase this system, you have made a great decision. As a bonus I have added a video below with the installation process explained, so you do not have to do it yourself.
