The Ultrefiner Elite delivers superior filtration
The Ultrefiner Elite system uses reverse osmosis technology to filter extremely small particles, particles that can easily slip through a less sophisticated filter. The Ultrefiner II is installed with a contemporary, lead-free RainSoft faucet offered in either brushed nickel or chrome to accommodate any home décor.
Model Ultrefiner Elite is tested and certified by NSF International against NSF/ANSI standard 42, 53, 58, 401, and CSA B483.1 for the reduction of claims specified on the performance data sheet. Ultrefiner Elite is certified by IAPMO R&T to NSF/ANSI 53 for the reduction of Total PFAS. Refer to the manufacturers Performance Data Sheet for specifics.
How an Ultrefiner Elite Drinking Water System Works
-
Unfiltered water enters the system from the inlet valve.
-
Water flows through the pre-filter which reduces particles and chlorine taste and odor.
-
Water then enters the Ultrefiner Elite reverse osmosis stage where it is flittered through a spiral wound, permeable membrane.
-
The resulting highly filtered water enters a storage tank.
-
Your reverse osmosis water is finally filtered through the post-filter and delivered through a dedicated drinking water faucet to enjoy cleaner, better-tasting water

Ultrefiner Elite Drinking Water System for Refridgerators with Ice and Water
For optimal refrigerator performance and water quality the recommended Total Dissolved Solids (TDS) level is generally between 50 and 150 ppm. This range balances the presence of essential minerals with the avoidance of excessive mineral buildup that can clog or damage refrigerator components.
-
TDS and Appliances:
High TDS levels in water can lead to scale buildup in refrigerators, especially in ice makers and water dispensers. This buildup can reduce efficiency and potentially damage the appliance over time.
-
Taste and Health:
While high TDS levels aren't necessarily harmful to health, they can affect the taste of water, making it taste salty or metallic. A TDS level between 50-150 ppm is generally considered ideal for drinking water, providing a good taste.
-
Specific Recommendations:
-
50-150 ppm: Excellent water quality with a balanced content and good taste.
-
150-300 ppm: Good water quality, but may have a slightly noticeable taste.
-
300-400 ppm: May cause scale buildup and a noticeable taste.
-
>400 ppm: Generally considered poor quality and may require treatment to reduce TDS.
-

Consult Your Owners Manual to see if water treatment is Recemended for your Refridgerator

The Ultrefiner Elite Alkaline Filter
This Alkaline Filter is sold as an accessory for use with other RainSoft Drinking Water Systems. It will moderately increase the pH of the water, measurably decrease the ORP (Oxidation Reduction Potential
– a measure of disinfection strength), and add some calcium and magnesium to the water.
The ideal application is when paired with the RainSoft Ultrefiner Elite Premium Drinking Water System. The Ultrefiner Elite, utilizing reverse osmosis in conjunction with other filtration methods, reduces the
level of dissolved solids in your water. This provides excellent protection against potentially harmful contaminants, but also leaves the water with a slightly lower pH and mostly free of minerals. The
Alkaline Filter can be used to raise the pH above neutral levels and add a small amount of beneficial minerals to the treated water

Drinking alkaline water is thought to offer some potential health benefits, although more research is needed to fully confirm all of them. Here's a breakdown of the reported advantages:
1. Hydration:
-
Studies suggest that alkaline water may improve hydration compared to regular water, potentially due to the added minerals and electrolytes it contains.
-
Some research indicates that athletes who consumed alkaline water showed improved hydration and more efficient lactate utilization after intense exercise.
2. Acid Reflux Relief:
-
Alkaline water's higher pH level (around 8 or 9) may help neutralize stomach acid, which could provide relief from acid reflux symptoms.
-
Research suggests that alkaline water with a pH of 8.8 can deactivate pepsin, an enzyme involved in acid reflux, potentially offering therapeutic benefits for those with reflux disease.
3. Bone Health:
-
Alkaline water may contribute to bone health by reducing the body's need to draw minerals like calcium and magnesium from bones to neutralize acidity.
4. Potential for Longevity and Overall Wellness:
-
Alkaline water is suggested to offer benefits like improved detoxification, a better acid-base balance, and increased energy levels.
-
There's also a theoretical possibility that alkaline water could contribute to increased longevity.5. Other Potential Benefits:
-
Some studies indicate possible benefits in managing high blood pressure, blood sugar, and cholesterol.
-
It might also offer antioxidant properties that protect against free radicals and oxidative stress.
-
Alkaline water is thought to support the body's natural detoxification processes.
