iSpring RCC7AK, NSF Certified, 6-Stage Superb Taste High Capacity Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization-Natural pH, White

iSpring

Based on 5 reviews Check latest price

Product description

As America's favorite brand of reverse osmosis systems, and backed by iSpring’s industry-leading customer support, the RCC7AK 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 extra layers of protection against harmful chemicals 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.

After flowing through the initial 5 stages of the iSpring RCC7 line of Reverse Osmosis filtering products, the RCC7AK model 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, some people may 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.

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 with no moving parts. 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 mounted on the counter as the primary source of drinking water, but output lines can also be connected to your ice maker, coffee maker, etc. The whole system is backed by a 1-year money-back guarantee, a 1-year manufacturer warranty and iSpring's unique lifetime technical support provided right here in the USA in Alpharetta Georgia. With the iSpring RCC7AK, enjoy crisp-tasting, bottled quality water, every day, right in your home.

Provides an easy way to visually inspect the sediment filter and view the contaminants being removed from your water. With the transparent housing you will know it is time for a filter change before a problem occurs.

Finest Micron, Layered Protection

The advantage of having both 5-micron GAC & CTO filters is that loose carbon (GAC, KDF) is better at trapping large contaminants, leaving only smaller ones to the CTO carbon block filter. This allows the CTO filter and RO membrane to function at their maximum efficiency and last longer.

Can the system reduce TDS?

To come straight to the point, TDS value isn’t directly related to water quality.

TDS stands for total dissolved solids. The higher the TDS is, the more impurities water contains. But what are impurities on earth? No matter beneficial natural minerals or harmful substances, they are all regarded as impurities in water.

As a result, water quality can’t be determined only by TDS value. It is just one of standards that reflect water condition and you can’t conclude that water with low TDS is definitely of good quality.

TDS has more influence on water taste, not overall water quality.

Waterdrop under counter water filter reduces harmful pollutants while retains natural minerals, thus ensuring purity and good taste of water at the same time.

Can the product filter well water?

No. This system is designed for Municipal Tap Water. If using well water as the source, please make sure the feed water has been through a pre-filtration system, otherwise, large particles in well water will clog the filter easily and shorten filter life. For the solution with a pre-filtration system, please search for WD-PFK on Amazon.
