Stage 3: This extruded activated carbon block filter boasts impressive capabilities. Reduces levels of lead, cysts and dangerous chemicals. The mesh of the ingredient carbon provides for chlorine removal and a dirt / sediment rating of 0.5 micron nominal & 1 micron absolute.** This provides cyst removal such as Cryptosporidium & Giardia. The turbidity reduction characteristics allow for even asbestos removal. Lead is removed by incorporating an ion exchange filter media into the carbon block extrusion.
