Improve your water supply with the whole house 3-stage Big Blue water purifier coupled with a 55W UV sterilizer. This water filtration system is perfectly suited to purify rainwater and municipal water that may have been contaminated by bacteria or protozoa (including E.coli and Giardia). It can process wellpoint water if it does not contain any heavy metal pollutants, mineral pollutants or salt.

  • Flow rate of ±2720 litres per hour (equivalent to 5 large taps open simultaneously)
  • Sediment filters remove unwanted particles such as sand, algae, rust, mud, slime and others from your water
  • Carbon filters remove chlorine and organic compounds while improving taste, colour and odour of water
  • UV (Ultra Violet) light disinfects water by neutralizing from harmful bacteria, protozoa and spores
  • Installs easily and neatly against a wall, either in the garage or outside in a shaded area

The system comes with a complete set of 3 filter cartridges (5-micron sediment filter, carbon block filter, 1-micron sediment filter) suitable for most rainwater and municipal water filtration needs in South Africa. The cartridges are fitted into the system.

Filter cartridges must be replaced every 6 months or when water pressure drops. The 55W UV bulb must be replaced every 12 months. It is always recommended that installations are done by certified plumbers. This system IS NOT designed to filter borehole water. Please, contact us for borehole water treatment advice.

Ask a Question
  • Does the Big Blue system remove flouride from municipal water?

    Dear valued customer,

    This unit won't be sufficient for removing flouride from your water. It is recommended to use Reverse Osmosis to remove flouride.

  • I have a big build up of sand in the filter, preventing me from removing the filter can you help

    Dear valued customer,

    For a stuck housing, it is recommended to use a Big Blue spanner for removal operations.

  • What will take the brown color out of the water

    Best is to have your water tested (SANS241 microbiological & chemical) and send results to info@ecodepot.co.za, as the colour can be due to different pollutants (not necessarily sediments). The most secure way to purify it is with a reverse osmosis system, but if the water is very dirty, the RO membrane is not going to last long.

  • Can it also remove salty taste from water?

    Dear valued customer,

    Indeed, the Big Blue 3-stage unit has a carbon block as its second stage. This is highly effective at removing chloride ions from your water supply.

  • How much is the flow resistance that is added by pumping through the 3 stage filter system ? Thanks


    It shouldn’t be much, the only time it will start slowing the flow down is when the filters start fouling up.
