SPRINGFRESH RO removes more than just chlorine taste and odor from drinking water. Each of the five stages of water filtration performs a unique purification function, delivering pure, safe drinking water for the entire family. This powerful reverse osmosis system starts the purification process by removing tiny particles like rust, sediment and insect parts. This protects your family. The 2nd stage of sediment filtration prevents the filtration systems from clogging the membrane. Next, the water flows through an activated carbon block cartridge. This compressed carbon block filters remove taste and odor-causing chemicals like chlorine, chloramine and rotten-egg odors. But thats not all. Did you know that the chlorine disinfection process can create cancer-causing byproducts in the water? The good news is these carcinogens, called THMs, are removed by the carbon filters. The carbon cartridges also remove organic contaminants like herbicides, insecticides and industrial chemicals that seep into groundwater.
