Water Filter Media

Clarence Water Filters Stock a wide range of water treatment media, including activated carbon, calcite, polyphosphate, corosex, resin, glass, and KDF.

Water treatment media can be used to achieve many goals including chemical reduction, pH correction, hardness and TDS reduction, and scale reduction.

Refillable filter cartridges are available to suit most filter housings, including 10″ x 2.5″, 10″ x 4.5″ and 20″ x 4.5″ cartridges.

Using refillable cartridges with media is an economical way to make your our water filters which target the specific contaminants you are concerned about.

Activated Carbon Media

Activated carbon can be used to filter chemical contaminants and bad taste/odour from air and water.

There are many types of carbon, designed to achieve specific objectives. The most popular options include:

  • GAC – Granular Activate Carbon (Coconut Carbon)
    Made from crushed coconut shells, excellent for removing chemicals and bad taste/odour.
  • ORC – Catalytic Carbon (Coconut Carbon)
    A type of GAC carbon which has received additional processing to increase the number of pores on its surface. The additional surface area improves chemical reduction rates and carbon capacity. It is capable of breaking up more complex chemical molecules, which standard GAC can struggle with. Particular useful for treating water supplies with chloramines (chlorine + ammonia).
  • Silver Impregnated Carbon
    GAC carbon impregnated with bacteriostatic silver (bacteria-killing). The best choice for treating unchlorinated water which may contain bacteria. Please not: Silver impregnated carbon prevents bacterial growth inside of the cartridge itself, but bacteria can still flow through the filter. Ideal for tank and bore water.
  • Coal Based GAC Carbon COL-L60 
    Removes chemicals and bad taste/odour in a similar way to Coconut based GAC carbon. However, offers improved results for removing TPH Total Petroleum Hydrocarbons.
  • VOC Removal From Air COCO-A55
    Coconut carbon that has been processed to enhance its ability to remove volatile organic compound gasses. Ideal for use with 3D Printers, which often emit VOCs when in use.

Carbon pellets to remove odours from range hoods or vents.


Calcite is used to correct low pH which can cause a reaction with copper resulting in green staining.


Polyphosphate is a slow dissolving media used to reduce scale built up in hard water areas.

Kinetic Degradation Fluxion (KDF)

KDF55 and KDF85 are used to strip active Chlorine and Sulphur odours and will increase the service life of carbon.

Ion Exchange Resin

Resins are used to soften hard water and remove TDS’s from water.
