iSpring RCC7AK Under Sink Reverse Osmosis Water Filter System with 3-Year Replacement Supply Set

As America's favorite brand of reverse osmosis systems, the iSpring RCC7AK is unequaled in quality, performance, and durability, backed by iSpring's industry-leading customer support. Designed to provide the best home drinking water filtration available, the system consists of a 6-stage, layered filtration built around precision reverse osmosis (RO) technology that removes over 1000 different kinds of contaminants.

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. Featuring a 75 gallon-per-day capacity RO membrane, larger than most in its class, the system can 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, as the RO process effectively generates pure water but also removes a few helpful minerals in the process.

The red mineral stone portion of the AK filter adds back healthy minerals including calcium, magnesium, sodium, and potassium, while the calcite portion neutralizes the pH of the RO water, resulting in a more natural taste preferred by many.

Designed for do-it-yourself installation under a standard kitchen sink, the entire system is straightforward to install, with all necessary parts included, along with clear instructions, instructional videos, and access to iSpring's unparalleled technical support. The system is quiet, low maintenance, and has no moving parts.

The lead-free, solid brass faucet with brushed nickel finish 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, and more. 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.

The F28K75 3-year filter pack comes with a total of 28 replacement filters, including 6 each of sediment, GAC, and CTO filters, 1 RO membrane, 3 post-carbon filters, and 6 alkaline mineral filters. This filter pack fits the iSpring RCC7AK, RCC7P-AK, and most other 6-stage RO systems.

Certified to NSF/ANSI 58, the iSpring RCC7AK Reverse Osmosis water filtration system converts your water into clean, pure, and healthy drinking water by removing up to 99% of over 1,000 harmful contaminants. The system's Alkaline Remineralization filter restores healthy minerals and produces a balanced alkalinity, giving your water a more natural taste than regular 5-stage RO water filters.
