Boasting unmatched efficiency, the RS4000 can also vastly improve the quality and taste of your water. This is achieved with the removal of impurities that are typically found even in water that has been purified prior to making it to your taps. With this water filter, you’ll be able to reduce impurities that could include asbestos, lead, and chlorine.

Alkaline water is also known as ionized water, and does offer a number of benefits for your health. With an alkaline water filter, your filtered water will be infused with vital minerals that were removed during the purification process; these minerals include magnesium, sodium, calcium, and potassium.

The system is easy to use and offers the efficiency that you are looking for. It can filter up to 5,600 litres of crisp filtered water, which is about four to six months of improved taste and health in water.

Connecting easily to your tap, this water filter is a practical and convenient solution for your home. It offers a user-friendly design that is all at once simplistic and efficient. No specialized tools are required for changing out the filters, and the process itself is easy and swift. With quick-change cartridges, you’ll be able to replace used cartridges fast and clean, without the need to touch the filter material itself.


A four-stage system, the twist and change cartridge design is a revolutionary solution to pure filtered water in your home.

  • Stage 1 is a 5-micron sediment filter that effectively removes particles like rust, sand, and dirt
  • Stage 2 is a granular activated carbon filter that effectively and efficiently removes up to 99% of the chlorine and organic chemicals that were added during the process of purification. This helps to boost the taste of the water, and also eliminates any potential unpleasant odors
  • Stage 3 is a second granular activated carbon filter that removes any remaining chlorine and organic chemical that stage 2 may not have captured. This will provide an enhancement in the taste, smell, and colour of the water
  • Stage 4 is an alkaline filter that transforms your water into a natural alkaline ionized water. This filter’s job is to reintroduce the potassium ion, ionized calcium, sodium, and magnesium removed during the purification process

Arriving completely assembled, the RS4000 is sterilized and ready to be installed. The dimensions assure you of a product that does not take up much by way of space in your kitchen, while the 6.0 kg weight makes it easy to handle.

As one of the most technologically advanced home water filtration systems, this alkaline water filter offers you great tasting crisp water that is assuredly safe to drink.
