iSpring RCC7P-AK 6 Stage RO Water System Membrane Reverse Osmosis Filtration Under Sink Water Filtration System with Brushed Nickel Faucet

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 healthy 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 healthy minerals.
