STAGE 1 FILTER: 1 micron carbon block: for taste and odor removal as well as heavy sediment removal for clear turbidity free water with a very pleasant taste.
STAGE 2 FILTER: 100% ACTIVATED ALUMINA: Up to 95% reduction of fluoride and arsenic. Activated Alumina is made from Aluminium Hydroxide by dehydroxylating it to produce a highly porous material; this material can have a surface area significantly over 200 m²/per gram (2,152 square feet/per gram). This very high surface-area-to-weight ratio gives it many “tunnel-like” pores for capturing (filtering) Fluoride, Arsenic and other toxins in drinking water. It is made of Aluminium Oxide (alumina; Al2O3), the same chemical substance as RUBIES & SAPPHIRES (but without impurities that give those gems their color). Activated alumina has also been identified by the EPA as a Small System Compliance Technology (SSCT) for uranium, and can remove up to 99 percent of the contaminant, depending on pH and concentrations of competing ions. It is also effective at removing other ions such as arsenic, fluoride, sulfate, and selenate.
STAGE 3 FILTER: KDF55 Combined with catalytic carbon for reduction of following: KDF55: Heavy metals such as (lead, mercury, nickel), chlorine, acts as a bacteria and scale control media.
