The process starts by passing water through a 5-micron polypropylene pre-filter cartridge. This SEDIMENT FILTER captures particulate matter like rust, sediment and dirt, while preventing the filtration systems from clogging with fine debris. Next, the water flows through two 5-micron organic coconut shell activated carbon block cartridges. These CARBON FILTERS act as polishing filters by removing tastes and odors caused by chlorine and chloramine disinfection chemicals, and remove carcinogens and organic contaminants like industrial chemicals. Then, the THIN COMPOSITE MEMBRANE removes heavy metals like lead and mercury. Salts, fluoride, and radon are also removed. Next, the GRANULATED ACTIVATED CARBON (GAC) cartridge removes organic chemicals as well as chemicals that give objectionable odors or taste to water such as hydrogen sulfide and chlorine. Finally, the Alkaline Remineralization filter restores healthy minerals and a natural alkaline balance.
