The traditional reverse osmosis system is known for removing beneficial that are important to our body leaving you with unnatural and slightly acidic water. The alkaline remineralization stage help restores those healthy minerals, therefore, provide more natural and alkaline water. Find out the best Alkaline reverse osmosis system
What is Alkaline reverse osmosis system
Most reverse osmosis system goes through the common 4-stages purification process but through the process important minerals like calcium, potassium, sodium, phosphorus, chloride, and magnesium.
Since these minerals are essential to our health and our body does not produce naturally we need a way to restore.
Adding another stage to our reverse osmosis is one way to restore minerals in your water and that’s where Alkaline reverse osmosis system comes in.
Alkaline reverse osmosis is a system with Alkaline Filter for Added Essential Minerals.

Alkaline reverse osmosis system reviews
The iSpring RCC1UP-AK is equipped with a booster pump and filter water in the 7-stage water purification process. The stages are:
3 Pre-filters: PP sediment filter, Carbon KDF (GAC) filter, and Carbon block (CTO) filter. The pre-filter helps remove large contaminants and protect the RO membrane from chemicals like chlorine and chloramines.
Reverse Osmosis (RO) filter that removes contaminants down to 0.0001 microns
Fine GAC filter that provides final polishing before the purified water is delivered to the faucet.
11-watt Ultraviolet Sterilization stage that helps kill viruses and bacteria
Alkaline Remineralization filter stage that help restores healthy minerals and a natural alkaline balance, while also producing a more natural taste.
It operates at a maximum feed water temperature (F)-100 and maximum feed water pressure (psi)-80.
The RO membrane provides 100 gallons of water per day and filters down to 0.0001 microns.
The system has an alkaline remineralization filter that helps balances pH and reintroduces healthy ionized minerals and 11W ultraviolet sterilizer that help kill viruses and bacteria. The UV sterilizer powers on and off with water flow
Ispring products are tested annually to remove up to 99.99% of harmful contaminants that commonly appear in municipal and well water. Also, the filters, tanks, tubing, and other water-contacting parts are manufactured to comply strictly with NSF/ANSI standard (58 for reverse osmosis).
It has transparent 1st stage housing. Transparent housing provides an easy way to visually inspect the sediment filter, view contaminants removed from your water, and know when it is time to change the filter.
