iSpring RCC7AK 6-Stage Under Sink Reverse Osmosis Drinking Water Filter System with Alkaline Remineralization - Natural pH, Brushed Nickel Faucet

  • This under sink mounted 6-stage reverse osmosis water filtration removes up to 99% of over 1, 000 contaminants, including lead, chlorine, fluoride, arsenic, 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 acidic water with a pH of 7. 0 or below. The iSpring RCC7AK includes an additional sixth stage - an Alkaline Remineralization filter, which produces balanced alkalinity.
  • Clear see-through 1st stage housing makes filter inspection a snap.
  • Do-it-yourself installation, with all parts included and well-organized instructions and videos, typically in a couple of hours with industry-leading help just a phone call away. Fits under a standard kitchen sink. For leak-free installation, simply push tubing ½ inch deep into quick-fitting connectors and lock - no threading pipes needed.
  • Prop 65 Warning: the product contains the material PVC that is commonly used in plumbing pipes and fittings. Per California law, this warning is added for public awareness.

    • The RCC7AK multilayer membrane, rated for up to 75 gallons per day.

    • The RCC7 line is one of America's top selling brands of water filtration systems. All of our systems go through rigorous testing for air leaks, pressure and cycle resistance to maintain our own quality and performance standards.

    RCC7AK Performance

    The RCC7AK is a multi-layered filter system that can removes over 1,000 different types of contaminants, including arsenic, asbestos, chlorine, fluoride, lead, mercury, sodium, and more.

    • 3 Pre-filters: PP sediment filter. Carbon KDF (GAC) filter. Carbon block (CTO) filter. They remove large contaminants and protect the RO membrane from chemicals like chlorine and chloramines.
    • The heart of the system is the Reverse Osmosis (RO) filter that removes contaminants down to 0.0001 microns – so small that only water molecules can squeeze through but virtually nothing else.
    • Fine GAC filter provides final polishing before the filtered water is delivered to the faucet.
    • An Alkaline Remineralization filter restores alkaline balance.


    Highlight Features

      • Reinforced Transparent 1st Stage Housing
        Provides a way to visually inspect the sediment filter. With the transparent housing you will know it is time for a filter change before a problem occurs.

      • 5- Micron, Layered Protection
        The advantage of having both 5-micron GAC & CTO filter is that the loose carbon (GAC) can trapping large contaminants, leaving only smaller ones to the CTO carbon block filter. This allows the CTO filter and RO membrane to function longer.

    • Leak-Free System & Online Supporting Videos
      Push to connect fittings and color coordinated tubings for the installation process, and our DIY installation video and customer support are both available if needed.

    Product Description


    The system consists of 6-stage, layered filtration built around reverse osmosis (RO) technology that removes over 1000 different kinds of contaminants.

    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 alkalinity and mineral balance of the water.

    Designed for do-it-yourself installation by most users, the entire system fits under a standard kitchen sink. All parts necessary for installation are included. Instructional videos and access to iSpring’s technical support. Replacement filters are standard sized. 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 lifetime technical support provided right here in the USA in Atlanta Georgia.
