The iSpring RCC7AK-UV is yet another top-notch model within the iSpring RCC7 series. It’s the variation of the iSpring RCC7AK model offering the same great RO system that features a remineralization filter but with the addition of a UV light filter.
iSpring RCC7AK-UV is a deluxe multi-layered reverse osmosis system that provides optimal protection against more than 1,000 different types of contaminants including arsenic, asbestos, chlorine, hormones, fluoride, lead, mercury, sodium, bacteria, giardia, viruses and more.
The RO system consists of 7 processing stages, the first 6 stages work similarly to the previous system RCC7AK, the 7th stage is an 11W UV bulb as an additional protection layer that against the variety of microorganism that past the RO filter.
The RCC7AK-UV comes equipped with 7 filtration stages which makes it one of the most comprehensive RO systems from iSpring and one that guarantees the best water quality possible.
The initial 5 stages consist of the standard iSpring’s 3 pre-filters we’ve seen in the other models and they remove all large contaminants down to 5 microns and chemicals particularly chlorine and chloramines.
They are followed by the 0.0001-micron RO membrane that removes up to 99% of all the remaining contaminants. The fifth stage is a finer GAC filter which gives the RO water the final polishing as it leaves the RO tank.
After passing through these initial 5 stages, the RCC7AK-UV model incorporates two more stages comprising of an alkaline remineralization filter and a UV sterilization filter.
Sixth Stage – Alkaline Filter
The 6th stage of the RCC7AK-UV uses an alkaline remineralization filter which is made up of red mineral stones that restore the healthy minerals removed from the RO water by the initial 5 stages. It adds back calcium, magnesium, potassium, and sodium.
The filter also has a calcite portion which helps raise the pH level of the RO water to natural alkaline balance giving a better and more natural taste. This is essential as the RO filtration process reduces the pH value of the water making it tastes slightly acidic.
Seventh Stage – UV Sterilization Filter
The final stage in this RCC7AK-UV system features a UV sterilization filter that offers an additional level of protection from possible microorganism contamination.
The filter uses a powerful 11W UV lamp which emits UV light as the water passes through it. The UV light kills 99.99% of harmful organic microorganisms that might seep past the RO filters including bacteria, protozoan cysts and viruses.
To ensure great efficiency, the unit comes with a smart flow sensor switch too which turns off the UV light once the water is not flowing through it thereby saving power. The UV lamp also comes in a protective stainless steel housing to ensure its durability.
The RO membrane of the RCC7AK-UV can deliver a maximum of 75 gallons per day. The capacity might vary though based on your source water pressure and temperature but it’s able to meet the needs of most small to medium-sized families.
The system, however, wastes around 3 gallons of water for every one gallon of clean water it produces. Considering that most of the other iSpring’s model has an average ratio of 2:1, this one will slightly waste more water unless you install a booster pump alongside it.
Installation and Maintenance
As with the other iSpring models in our list, the RCC7AK is not that hard to install yourself if you have basic DIY skills. Everything you need to set it up is provided and the instruction manual is user-friendly with pictures and illustrations that make it easier to understand and follow. The whole unit is compact and will nicely fit under any standard kitchen sink.
Overall, the quality, performance, and features of this RO system are really commendable. By combining both the alkaline and the UV lamp filter means you are always assured of clean, healthy water that has a much better and natural taste throughout.
It’s a system we would highly recommend for anyone wanting a unit that offers more than just the standard RO filtration process.
