If you want a reverse osmosis system that is packed with features, you will absolutely love this iSpring selection.

Filtration Process

The iSpring RCC7AK-UV reverse osmosis water filtration system uses seven different stages—which we will go over soon—to ensure you get great tasting purified water. It uses CTO and GAC filters to ensure your RO membrane is well-protected from larger contaminants and can filter up to 75 gallons of water per day, which makes it perfect for larger households.

Stages 1-3: Prefiltration

The first three stages of this RO system is the prefiltration process. This part of the filtration process will get rid of larger debris and contaminants in your water to prevent your reverse osmosis membrane from getting damaged. Between the sediment filter, the GAC filter, and the CTO filter, your water will be freed of chemicals, chlorine, chloramines and so much more!

Stage 4: Reverse Osmosis Membrane

Without the reverse osmosis membrane, this water filtration system would not do what it is designed to do—which is why the first three stages are incredibly important. When your water supply reaches
the reverse osmosis membrane it is already free of larger contaminants. During this stage, the system will get rid of contaminants as small as 0.0001 microns and your water supply will be purified.

Stage 5: UV sterilization

If you have low quality water in your home, the UV sterilization process is just the thing you need. This process is especially essential for those of you who use well water because it will kill bacteria, microorganisms, protozoan cysts, and viruses and that settle in your water. This stage features an 11 watt UV sterilization lamp that automatically turns on and off when your water flows, so you don’t have to worry about wasting additional energy with this system.

Stage 6: Water Remineralization

During the filtration process your water supply will be completely stripped of everything—even beneficial minerals like Calcium and Magnesium. This leaves your water hard and throws off its alkalinity. The water remineralization process will restore the waters alkalinity and improve its tastes by reintroducing Calcium and Magnesium to your water supply.

Stage 7: Water Softening

The last and final stage of this system is the water softening stage. Here the system uses a GAC filter to polish and soften your water, so it tastes great up until it is time to replace the filter.
