That’s right, a coconut. Scientists chose coconut shells as a carbon source for our water filters because studies show it works much better than other sources, including coal.
“You can use less of it, and it’s a higher quality,” Amway Research Scientist Karen VanderKooi said. “It’s also abundant and renewable.”
The activated shells are extra porous, which makes them superior at attracting contaminants.
Our suppliers use the charcoal from burned coconut shells, typically used for simple fuel, and treat them with high temperatures to make “activated carbon” granules. The granules are then ground to a fine powder, pressed into a block and fit right into our eSpring cartridges.
The size range of the powder particles is patented and unique to eSpring, says Karen.
“It’s why the carbon filter can reduce over 140 potential health-effect contaminants and can treat up to 5,000 liters of water before needing replacement,” she said.
