Filter Stages

1. Fine Steel Mesh

Reduces dust and bigger particulate and provides structural support for the filter.

2. Polypropylene Cotton

High Surface area to reduce finer sediment, turbidity, micro-organisms and rust.

3. Magnetic Energy Ball

These natural stones charge the water in order to help drain toxins from the body, lessen inflammation and boost the immune system.

4. Maifan Stone

Improve the biological activity of water with dissolved oxygen concentration. Maifan Stone has a strong adsorption ability to heavy metal ions and toxins in the water, it can reduce the concentrations of bacteria and inhibit its reproduction speed. This helps reduce mercury, lead, cadmium, arsenic and other heavy metals and chlorinated, and other harmful substances to purify water.

5. Mineral Ceramic

Made from mineral compounds that soften water. Helps further absorb heavy metals and reduces odours.

6. Calcium Sulphite

Calcium Sulphite has a strong de-chlorination ability that works even at hot water temperatures with extremely fast effectiveness. It is also able to absorb heavy metals.

7. Alkaline Ceramic

Made from mineral compounds that soften water. Helps further absorb heavy metals and reduces odours.

8. Ceramic Balls

FAR Infrared emitting stones

9. KDF-55

Uses a combination of Copper and Zinc to create a redox reaction. This process reduces chlorine, hydrogen sulphide, heavy metals and iron. It also helps inhibit the growth of algae, fungi and bacteria.

10. Activated Coconut Carbon

Activated Carbon is a common material used for water and air filtration. It is effective at removing chlorine, removing taste & Odours from water. It is also used to absorb organic matter from water.

11. Polypropylene Cotton

High Surface area to reduce finer sediment, turbidity, micro-organisms and rust.

12. Fine Steel Mesh

Reduces dust and bigger particulate and provides structural support for the filter.

KDF-55 Filtration

KDF media (or Kinetic Degradation Fluxion Media), is a chemical compound used in water filtration applications. KDF is often used alongside activated carbon to maximise the efficiency of the filter. Generally, KDF is used in a purification system as a pre-filter, before another, finer stage of filtration, for example, reverse osmosis, de-ionisation and ion exchange systems.

KDF is regarded as being one of the newer developments in water treatment and filtration, since its development in 1984, it has grown to be widely regarded as one of the best filtration media available.

Water passes through a bed of pure KDF or an Activated carbon/KDF mix. As the water makes contact with the KDF particles the Redox reaction takes place, removing such impurities as minerals, metals, dissolved oxygen and organic materials. The KDF itself creates a miniature electrolytic cell within the spaces between each particle, the zinc acting as the anode and the copper acting as the cathode within this cell, and the water and its impurities acting as the electrolyte through which the charge flows. When the contaminants and impurities found in water pass through this electrolytic cell, some substances, especially metals, react to the magnetic force exerted by the electrolytic cell and are attracted to the surface of the KDF particles, where they adhere.  Other non-metal impurities react with the KDF and form zinc oxides, copper hydroxides, hydroxides, and sulphates in the water. These by-products remain within the drinking water but are not dangerous, also as part of this reaction, ozone is created and carried through into the drinking water, forming a hostile and desolate environment for algae, bacteria and any other array of micro-organisms.

Replacement Filters

Cartridges can last 2-6 months depending on water quality and usage volume. To replace your cartridge simply turn off your mains water supply and unscrew the shower hose from the filter. Take off the outer casing pull out the old cartridge and put in the new one. Then screw the casing back on and screw the shower hose back onto the filter.
