The 100KDF water purification system is as follows: (refer to the picture)

A 5 Micron Filter Pad

Macro-filter to remove bigger granules.

Silver Impregnated Granular Activated Carbon

A thin layer of silver impregnated activated carbon protects the filtration media from back contamination of bacteria. Silver has long been used as a disinfectant in water purification.

Granular Activated Carbon (GAC)

GAC provides protection for home drinking water from chemical compounds manufactured or widely used after World War II. These include the chlorinated hydrocarbons in various pesticides, herbicides and industrial solvents. Misuse of these materials has allowed water supplies to become a problem.

GAC has proved to be an effective media for the removal of such contaminants, absorbing chlorine, other chemical compounds and gasses. GAC is a preferred method of protecting water from:

trihalomethanes (THM’s),











ethylene chloride




numerous other chemical compounds



GAC also traps organic material thereby removing bad tastes, colour and odours.


Riolyte is specially formulated mineral components that are mixed into the media bed.

Riolyte gently releases these minerals into the water making it more palatable, as well as improving the PH of the water, making it more alkaline.


Even though GAC is sufficient to correct the problems of 85% of today’s household water, to make the process more complete, we have added the patented KDF to our systems.

KDF significantly removes:

  • iron,
  • aluminium,
  • sulphur, as well as
  • heavy metals (lead, mercury, arsenic & many others) and
  • kills bacteria, fungus and algae.

KDF makes our units completely bacteriostatic; no bacteria will grow in the unit and the life of the cartridge is prolonged.

KDF & Riolyte are registered trademarks of H2O International.

Over the last two decades many scientific institutions have successfully tested the contaminant removal capabilities of the H2O range of products with outstanding results.

Water Volume 70,000 litres or 3 years (which ever comes first)

The 100KDF is a replacement and upgrade for the NSA 100SX filters
