Premium under-counter water purification

Rainwater Superior is an under-counter purifier that treats mains water with a four-stage reverse osmosis system and enriches it with beneficial minerals through its alkaline mineral filter. Its compact body takes up little space in the kitchen cupboard.

  • Multi-layer purification

    Reverse osmosis technology separates heavy metals (lead, mercury, arsenic), nitrate/nitrite, pesticides, persistent chemicals (PFAS) and microorganisms from the water.

  • Alkaline mineral (8+ pH)

    After purifying the water, it re-enriches it with vital minerals such as calcium, magnesium and potassium. It offers a soft, great-tasting drinking profile that supports the body's pH balance.

  • Stainless steel tank

    Purified water is stored in a corrosion-resistant grade 304 stainless steel tank.

  • Smart LED filter monitoring

    The LED light system on the tap shows the filter status with colour codes.

Easy installation

Thanks to its space-saving compact design, you can easily place your Superior Alkaline system in your kitchen, office or any other space you like. Its light, portable build makes it very practical to move the system elsewhere whenever you need to.

Easy filter replacement

Filter replacement is now much more practical. All you need to do is follow the steps shown in the filter replacement guide, place the filter in its slot on the connector and twist it gently.

Dispenser conversion

With a configuration designed specifically for your non-purifying water dispenser, our Superior Alkaline under-counter model integrates easily into your system. Your dispenser then stops simply dispensing water and becomes a station that always provides fresh, purified, alkaline water.

Multi-Layer Hyperfiltration Technology

  1. Through the connection, mains water first enters the pre-filter, which has 5-micron pores. The job of this high-tech filter is to remove coarse impurities in the water, that is, sediment such as dust, sand, algae and insects, down to 5 microns. Even after the sediment filter has captured suspended particles and bacteria larger than 5 microns and the water has become much clearer, it may still contain some microorganisms, dissolved chemicals and minerals.

  2. The water then reaches the carbon block filter. The job of the carbon block filter is to remove organic matter that causes unpleasant taste, odour and colour, as well as chlorine and any gaseous odours in the water. It makes the water tastier, clearer and odourless. It filters the water, which the sediment filter has filtered down to 5 microns, to a precision of 1 micron, providing advanced filtration.

  3. Hyperfiltration, the heart of the system, has a semi-permeable membrane structure. It operates at a pressure of at least 2.5 atmospheres. Its pores measure between 8 and 10 angstroms. Heavy metals such as lead, mercury, nitrate, arsenic and copper that may be dissolved in the water, as well as other chemicals or contaminants such as bacteria and limescale, have no chance of passing through this semi-permeable membrane, whose pores are about a millionth of a millimetre. Only water molecules and anions and cations beneficial to human health pass through this filter.

  4. Finally, on its way from the tank to the tap, the water reaches the alkaline filter, whose performance is doubled by the use of ceramic and coconut shell, to gain flavour. This filter's job is to remove odour-causing substances, prevent the formation of microorganisms and balance the pH of the drinking water between 8.5 and 9.0. Enriched with silver ions to improve its taste and with its alkaline pH raised, the water becomes rich in calcium, magnesium, sodium, potassium, iron, phosphorus and other minerals that nourish our bodies.
