In stage 1:
water flows through a 20″ sediment filter cartridge that removes sediment, silt, sand and dirt. Also extends the life of the water filters.
In stage 2:

GAC is universally recognized and widely used effective adsorbent for wide variety of organic contaminants, such as chlorine (99.9%), chemicals linked to cancer (THM’s, benzene) pesticides, herbicides, insecticides, volatile organic compounds (VOC’s), PCB’s, MTBE’s and hundreds of other chemicals.
