The eSpring Water Treatment System combines carbon block filter, UV light, and electronic monitoring. Users are usually fairly happy with this product; the filtered water taste good, and hardware lasts for years. It is a good quality water purification system no doubt, hence it comes with a hefty price tag. They are sold by Multi Level Marketers (MLM) which is also one of the reasons why these filters are more expensive.
eSpring’s ability to reduce the contaminants as claimed by Amway has been verified by certifications by third party water quality testing authority, NSF as well as WQA.
eSPRING Water Treatment Technology
Carbon Block Filter
Inside the eSpring Water Treatment System is an activated pressed carbon-block filter. This US patented multi-stage carbon block effectively removes:
- chlorine taste and smell
- particulates down to 0.2 micron, which improves clarity
- more than 140 possible health-effect contaminants, including lead, mercury, VOCs, and the petrol additive MTBE
While eSpring removes contaminants by trapping them in the patented carbon-block filter, beneficial minerals, such as calcium, magnesium and potassium, pass through unchanged and remain in the water. Activated carbon readily bonds to and adsorbs many organic carbon-based compounds such as pesticides and herbicides. The carbon in the filter bonds with organic, carbon-based compounds. Minerals and other inorganic compounds do not have a carbon base. Therefore, a bond usually will not form with the carbon, and the minerals will remain in solution in the water and pass through the filter. The carbon block cartridge is made of high-quality coconut shell-based activated carbon that removes contaminants effectively.
A patented shining light system, it emits up to 80 millijoules/cm2 of UV light and destroys more than 99.99% of bacteria and viruses that may be found in drinking water. Uses patented wireless inductive technology to power up the UV lamp, which results in greater safety and reliability. If there are bacteria present in the incoming water, they may grow in a carbon filter overnight, or during periods of inactivity. This is true for all carbon filters on the market – including those treated with silver. The eSpring Water Treatment System uses ultraviolet light to destroy any bacteria present in water after it leaves the carbon filter.
“Smart Chip” to display digital icons and audio cues of the machine’s condition on the LED screen. The monitor will also alert you when it is time to change the cartridge. Source
‘Smart chips’ in the eSpring monitor keep track of the UV lamp and filter life, and an LED display lets you know when the cartridge needs to be replaced.
Initially the carbon activation process leaves an alkaline surface on the carbon that is similar to baking soda. This alkaline surface raises the pH of water that initially passes through the filter to the 9-10 range. This pH shift is well within the acceptable range for drinking water. After approximately 58 litres (15 gallons) have passed through the filter, the pH level drops to about 8.5. After 190 litres (50 gallons) have passed through, water pH is between 7 and 8, nearly identical to untreated water.
NSF International is a non-profit organisation recognised worldwide as the leading independent testing and certification authority on water treatment systems. NSF has tested and certified the eSpring Water Treatment System for the reduction of more health-effect contaminants than any other UV/carbon-based system it has certified.

Amway eSpring is good, certified, has UV lamp to kill any remaining bacteria not killed by chrorine, unfortunately they are MLM and expensive.
Have been using for 10 years and no problem, no leaks, taste fresh, but expensive. Some complain the water taste bitter/ metallic after a while.
