• Reverse Osmosis requires high water pressure to force the impurities out of the water. RCC7P-AK’s extremely durable electric booster pump ensures high efficiency, reliable, and consistent performance regardless of pressure variations; delivering the highest performance for an RO system with less waste water..
• High Capacity Reverse Osmosis water filtration for safer, ier water. This under sink ed water filter and water softener removes up to 99% of over 1, 000 contaminants, including lead (removes up to 98% of lead), chlorine, fluoride, arsenic, PFAS, asbestos, calcium, sodium, and more..
• The RO membrane removes not only harmful pollutants but also a few helpful minerals. As a result, a standard 5 stage RO system produces slightly ic water with a pH of 7. 0 or below. The iSpring RCC7P-AK includes an additional sixth stage - an Alkaline Remineralization filter which restores y minerals and produces a balanced alkalinity, which gives the water a more natural taste than regular 5 stage RO water..
• With Premium quality components ensure highest reliability and low maintenance for many years to come. Clear see-through 1st stage housing makes filter inspection a snap. Pump power adapter: 100-240V 50/60Hz.
• For indoor use only. Extended Manufacturer upon registration, support from Atlanta GA USA.

As America's favorite brand of reverse osmosis systems, and backed by iSpring’s industry-leading customer support, 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. Unlike some other systems, the combination of both GAC and CTO filters in the 2nd and 3rd stages provides greater protection against harmful s 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 RCC7P-AK model of the iSpring RCC7 line of products is equipped with a booster pump for situations where inlet/house water pressure is low – below about 40 PSI. Reverse Osmosis requires high pressure to force the impurities out of the water. If the pressure is too low, the process will not be efficient. Adding a booster pump where the inlet water pressure is too low solves this problem by ensuring optimal pressure to the RO membrane at all times. Pure water can be produced more quickly with less water loss. The booster pump operates nearly noiselessly and only when needed. Usually it can barely be heard over normal kitchen activity. After flowing through the initial 5 stages of the iSpring RCC7 line of Reverse Osmosis filtering products, the RCC7P-AK model 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 it also removes a few helpful minerals in the process. The red mineral stone portion of the AK filter adds back y minerals including not just calcium, but also other beneficial minerals, like 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, many people find it tastes unnatural. Many people prefer the more natural taste that comes from the presence of some minerals in the water. Remineralization restores just the right proportion of y minerals. 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. The system is quiet and low maintenance. Replacement filters are standard sized and sold at factory direct pricing. A lead-free, solid brass faucet with brushed nickel finish is included with the system and is usually ed on the counter as the primary source of drinking water, but output lines can also be connected to your ice maker, coffee maker, etc. Incoming Water Pressure: 30 PSI - 70 PSI Operating water temperature range: 40 – 100 °F Maximum TDS: 750 ppm
