Overview
iSpring offers you a reliable, very efficient, and super quality product, that is designed and manufactured in America. The RCC7AK Reverse Osmosis Water Filtration System is bigger than some other products in the best RO systems class. It has a 75-gallon-per-day capacity RO membrane that is ideal for bigger families.
The system also has an additional 5th stage of filtration to the 4 mandatory stages. This is the Alkaline Remineralization (AK) stage which is designed to restore the natural alkalinity and mineral balance of the water. Many claim that alkaline water has countless benefits. The whole system can be easily installed under a standard kitchen sink. And the set includes a lead-free, solid brass faucet with brushed nickel finish.
Another great feature is the transparent 1st stage housing that will allow you to inspect the sediment filter and change it on time. The system is designed to be price effective. It uses plastic connectors which makes it affordable, but without any compromises over performance and longevity. Overall – a great product that will supply you and your family with pure, healthy, and high-quality drinking water.
Performance
This system removes up to 99% of over 1,000 contaminants including lead (removes up to 98% of lead), chlorine, fluoride, arsenic, hormones, asbestos, calcium, sodium, bacteria, giardia, viruses, and more. As you may know, in the process of RO, harmful pollutants are removed along with a few helpful minerals.
With its additional filtration stage and alkaline remineralization filter, this product will restore healthy minerals and the natural alkaline balance. The water passes through this filter before it enters the faucet and after the RO. The filter is made of half-red mineral stone and half calcite. Thus, it adds back healthy minerals that have been previously removed on the one hand, and on the other – neutralizes the pH. In the end, you get quality mineral water, right from the faucet.
Features
RCC7AK comes fully packed and ready to install. In the set, you’ll find premium quality components to ensure the highest reliability and low maintenance. A brushed nickel faucet, storage tank, shut-off valve and filter cartridges with RO membrane come along with the system.
The membrane is multilayered and rated with a capacity of 75-gallon-per-day. An upside is that you have both 5-micron GAC & CTO filters. The first is trapping large contaminants, leaving only smaller ones to the CTO carbon block filter. This way the CTO filter and RO membrane function with maximum efficiency and last longer. On top of that, you have the alkaline remineralization filter.
Installation and Maintenance
The installation of this system is straightforward and designed for DIY users. People with no experience might also manage but could need some professional help depending on their knowledge. The manufacturer has made an instructional video. You also get a push to connect fittings and color-coordinated tubings that simplify the process.
You will find well-written instructions and access to superb customer help in addition to what you can learn online from other users:
Regarding the maintenance – you will not need to do much. You have the 1st stage filter at a glance so you will know when to change it. 3 to 6 months is the suggested life of those filters, but some user reports talk about a shorter period due to very contaminated water. Some leaks are possible, but that depends a lot on your water pressure, installation, and housing. So be prepared. Overall – great product at a reasonable price.
