Advantages of the system:

  1. Remove Fluoride (reasons for no fluoride)
  2. Remove Chlorine
  3. Remove Cyst, Bacteria and Parasites
  4. Remove Lead and Heavy Metals
  5. Remove Insecticides and Herbicides
  6. Trace minerals essential to our bodies remained in filtered water

The system include two cartridges:

First Cartridge:
Remove Fluoride with activated alumina

Second Cartridge:

First Stage:  Doulton imperial ultracarb ceramic provides genuine sub micron filtration. The cartridge reduces fine particulate matter, bacteria, cysts and turbidity.
Second stage: The incorporation of silver locked within the ceramic structure gives enhanced bacteriostatic and self sterilizing properties.
Third Stage: An inner core of activated carbon block removes chlorine and organic compounds.
Fourth Stage: Ion exchange resin reduces Lead and other heavy metals.

Parasites, such as Cryptosporidium and Giardia 
Lead (150 ppb)
Particulate, rust, dirt (greater than 0.8 microns)

Class 1

> 98% efficiency at 0.2 microns
> 90% efficiency at 0.05 microns
