CTO Carbon Block Replacement Cartridge 20″

R 328.85
20" Big Blue

The 20″ Big Blue CTO Carbon Block Filter is a high-capacity cartridge designed to improve water taste, smell, and clarity by reducing chlorine and selected organic impurities. Its large-format size makes it ideal for whole-house filtration, borehole pre-treatment, reverse osmosis protection, and light commercial systems.

The compressed activated carbon block provides increased contact time as water passes through the filter, helping to adsorb contaminants while also reducing fine particles.

Key features

  • Reduces chlorine, unpleasant taste, odour, and selected organic compounds
  • Large 20-inch Big Blue format offers higher capacity and longer service life
  • Fits standard 20-inch Big Blue filter housings
  • Suitable for whole-house, borehole, RO pre-filtration, and light commercial applications

55W Stainless Steel UV Water Sterilizer

55 WStainless steelChemical-freeA UV water sterilizer uses ultraviolet light to neutralise bacteria, viruses, and other microorganisms in water without adding chemicals or changing the taste, colour, or odour of the water. It is an effective final-stage treatment option for borehole systems, municipal water supplies, drinking water systems, and whole-house water purification setups.As water flows through the stainless-steel chamber, it is exposed to UV light from the lamp. The ultraviolet rays damage the DNA of microorganisms, preventing them from reproducing or surviving. For best performance, the water should be clear before entering the UV unit, which is why sediment and carbon pre-filtration are recommended.Key benefitsDestroys up to 99.9% of common waterborne microorganismsChemical-free disinfection with no chlorine taste or by-productsInline system with no holding tank or reaction time requiredSuitable for point-of-use and point-of-entry applicationsHelps provide added protection for borehole and municipal water suppliesLow energy use and no water wastage during operationStainless steel housing for durable, long-lasting performance

Granular Activated Carbon (GAC) Filter
Replacement Cartridges

Granular Activated Carbon (GAC) Filter

GAC / UDFEffective carbon filtration for reducing chlorine, taste, odour, and selected organic impurities. Granular Activated Carbon, also known as GAC or UDF, is a porous carbon media designed to adsorb chlorine, organic compounds, and impurities that can affect the taste, smell, and colour of drinking water.As water passes through the carbon granules, contaminants bond to the large surface area of the media. Filtration performance depends on water quality, flow rate, and contact time. Slower flow allows longer contact with the carbon, improving results.Key benefitsReduces chlorine, unpleasant taste, and odourHelps improve the colour and overall quality of drinking waterLarge carbon surface area supports effective adsorptionSuitable for household drinking water systems and pre-filtration applicationsOuter cartridge colour or design may vary by batch, while the internal carbon media remains consistent
