Specs/Performance

Storage Tank Sizes

 Our Reverse Osmosis (RO) Storage Tanks are available in Large, Medium, and Small sizes to suit various household or commercial needs. While each tank is labelled with its total volume (which includes both the air chamber and the water bladder), the more important figure is the usable water capacity—this is the amount of water available at the shut-off pressure set by your RO system’s Automatic Shut-off Valve (ASV). Below are the tank options with key details, including their Model Part Numbers (MPNs) as printed on the tank label:

 Large (RO-132)
– Approx. 9L usable water capacity
– 18L total volume (as shown on tank/carton)
– Ideal for higher-demand households or where frequent water use is expected

 Medium (RO-122)
– Approx. 6L usable water capacity
– 12L total volume
– Suitable for general household use

Small (RO-120)
– Approx. 4L usable water capacity
– 8L total volume
– Best suited for limited space or low-demand use

System Dimensions:

Height: 43cm
Depth: 21cm
Width: 37 cm
NOTE: If height is a problem, you can detach the top 3 filters and place beside the system – this will reduce the total height to 39.5cm

High Alkaline Magnesium & Hydrogen Rich Water | The 7 Stages of Filtration

The first stage is a 5 Micron (uM) Sediment filter composed of 100% melt-blown polypropylene fibre. This cartridge helps to help protect the carbon pre-filters and reverse osmosis membrane from physical damage caused by particulate matter such as sand, dirt, silt, plant spores, and pollen. Physical contaminants such as these (which can surprisingly be found in most municipal water supplies), tend to clog up filter system components causing reduced water flow, lower osmotic pressure, diminished filtration efficiency, and ultimately, inferior water quality.

Physical contaminants such as these (which can surprisingly be found in most municipal water supplies), tend to clog up filter system components causing reduced water flow, lower osmotic pressure, diminished filtration efficiency, and ultimately, inferior water quality.

The second stage is a high-grade activated coconut carbon block pre-filter. The carbon block matrix enables maximum surface area and contact time, taking the first hit to adsorb chemicals such as Chlorine (which causes damage to the membrane), along with other harmful organic chemicals and contaminants. Keeping up with regular maintenance of this pre-filter (changing it every 6 months) is crucial to protecting and extending the life of all filters that come after it.

The RO membrane is the "engine room" of your RO system. All the crucial work is done here, so all the filters before the membrane are primarily there to protect the membrane. This membrane has a 0.0001 Micron rating and can produce up to 190 Litres (50 Gallons) of water per day.

This Filter is the Ultimate Post RO filter on the market. It is one of the only alkalising filters in the world that can raise and retain a constant pH between 8.5 and 10.5* over a 12 Month Period and potentially longer. This unique cartridge is made up of pure Sub-nanometer minerals and contains Magnesium and Potassium to provide superior pH stability in the high alkaline range. The media is agglutinated under high temperatures, whilst its anomalous surface enables greater surface area contact for the maximum level of mineralization. The T300 Filter also has the unique ability to produce Hydrogen-Antioxidants through the Hydroxide-Alkaline pH acidity balance of the Magnesium & Potassium media as it dissolves into the water. This high-quality, FDA Certified Cartridge has multiple beneficial effects on Drinking Water.

Infrared beads are simply miraculous given that they don't even come into contact with the water! Far Infrared Rays ionise and activate water molecules, and therefore may help improving blood circulation and overall health, given that water makes up over 70% of the mass of the human body. When FIR energy vibrates at a frequency similar to that of the human body, it may assist in activating cells, and strengthening the micro-circulatory system.

This filter ensures the maximum extraction of tastes and odours, whilst imparting a naturally "sweet" flavour into the water.

This inline magnetic water conditioner is designed to alter the structure of water by applying a strong magnetic field, helping to impart a negative charge to the water as it flows through. By influencing the arrangement of water molecules, it can reduce scale buildup, improve hydration, and support better absorption in both domestic and agricultural applications. Easy to install and maintenance-free, this non-chemical solution offers a continuous flow of conditioned water without altering its mineral content, making it ideal for users seeking the potential benefits of negatively charged water in a clean, efficient format.

RO Water Storage Tank Options Filter System

Because Reverse Osmosis membranes filter down to such a fine micron rating (0.0001 of a micron), they produce water at a very slow rate (on average 8 litres PER HOUR). This is why all plumbed-in RO systems come standard with a dedicated drinking water tap, and a water storage tank. Your water usage requirements and under-sink space can help determine which sized tank to choose from. Consider that the average person should drink 2L of water per day, and that the system will automatically re-fill at a rate of 8 litres per hour. Choose from a Small, Medium or Large (Standard) tank – the tank dimensions can be seen in the image below:
