Product Summary

Product Features

• 90%+ TDS (total dissolved solids) rejection rate.
• Exceptional purification - removes up to 98% of chemicals, heavy metals, sediment, and many other contaminants.
• Booster pump delivers up to 80 PSI, the optimal input pressure for reverse osmosis. Ideal for increasing the input water pressure if your home's water pressure is under 45 PSI. The minimum required input pressure for the RCC7P-AK is 30 PSI. Compatible with 110V and 220V power sources.
• Stage 6 Alkaline filter adds back healthy minerals that were removed during the RO process, including ionized calcium, magnesium, sodium, and potassium, and adds 0.5 to 0.8 in pH to help offset the pH lost during the RO process.
• Easy DIY installation with quick-fitting connections and wall-mountable bracket that fits under sink cabinets.
• New technology reduces waste water ratio to 3:1, the best in the market.
• Metal 3.2g NSF certified pressurized storage tank with high grade butyl diaphragm - can be positioned vertically or horizontally.
• Purifies up to 75 gallons of water per day. Can be used with heavily chlorinated water and well-water sources.
• Complete system comes ready for use with luxury goose neck faucet and all filters included.
• Reliable design and solid construction will provide years of top notch production.
• 30-day money back guarantee, 1-year limited warranty, and lifetime technical support.
• Note: If your incoming water pressure is above 45 PSI, we recommend our 6-stage RO system with no booster pump, model RCC7AK.

6. New RO Membrane (MC7): Using cutting edge machinery and quality 3M material, the new RO membranes deliver higher contaminant rejection rates on an extremely consistent basis.
7. Water Flood Alarm: Included with every RO system, the highly sensitive probe will detect water levels as low as 2mm and sound off with an extremely loud alarm. It is an excellent security blanket that provides additional peace of mind.
8. Revised User Manual: With an updated parts list, additional pictures, and a straightforward 8-step installation process, the user manual is now more user friendly and detailed. If you have any questions or concerns when installing, give us a call!

How It Works

Next, a 5-micron GAC filter reduces chlorine, tastes, and odors, as well as mineral oil, BTEX, Poly aromatic hydrocarbons (PACs), phenol, and halogenated substances.

At the 3rd stage, a denser carbon block filter removes any residual color, taste and odor (CTO), as well as difficult-to-remove chemicals such as chloramines.

The system's 4th stage of filtration is especially important, as it involves the pressing of water through the NSF certified reverse osmosis (RO) membrane, the same technology used to produce bottled water. This semi-permeable membrane features tiny 0.0001 micron sized holes, effectively removes arsenic, lead, perchlorate, chromium, copper, TDS (total dissolved solids), sodium, and a long list of other water contaminants. It also removes parasitic cysts, such as giardia and cryptosporidia.

The 5th stage of filtration utilizes a finer GAC filter, also known as the post carbon filter, which works as a final polishing filter when the water leaves the storage tank.

The RO water then passes through the Alkaline pH filter, which is the 6th and final stage before the water reaches the faucet.

The end result is bottled quality mineral water. In addition to the cost savings, widespread use of in home filtration systems would reduce the impact of plastic bottles on the environment tremendously. With all of the benefits, it only makes sense to go RO!
