Organic Minerals VS Inorganic Minerals In Water
Contrary to common beliefs, less than 1% of organic minerals are actually found in most raw water supplies. With the increase of pollutants, our water supply contains mostly inorganic minerals. Inorganic minerals consist of calcium, iron, magnesium, carbonate and lime compounds, which are not compatible with our bodies.
The body's cells reject these minerals leaving dissolved inorganic substances (acid crystals - minerals deposits) throughout the body. This accumulation of debris creates more work and trouble for the body, such as arthritis in joints, gallstones, kidney stones and mineral deposits in artery walls.
Organic minerals that are considered soluble (which means the body absorbs sustenance into the cells), are found in live foods such as fruits & vegetables. One glass of freshly squeezed orange juice would be higher in minerals than 30 gallons of untreated raw water.
Purified water provides a necessary rinsing treatment for hydration purposes as our body is mostly fluid (over 80% water) and equally important, is to rinse impurities out of our body. Drinking purified water both prevents inorganic minerals from entering our bodies and removes inorganic mineral deposits already there.

**IMPORTANT INFORMATION**
How often should you change reverse osmosis water filters?
Filter Replacements & Maintenance Schedule
To maintain the optimum level of filtration year-round, and to ensure you get the maximum life out of your RO membrane (the engine room of this system), we strongly recommend a consistent filter maintenance schedule.
-
Pre-Filters
Every 6 months you will need to change the pre-filters, which help protect and extend the life of the membrane. Some people neglect to keep up with the maintenance of the pre-filters, thinking that the RO membrane will take care of it! However, the RO membrane is the most delicate and expensive filter within any RO system, so it's worth protecting your investment!
The pre-filters thus serve the dual purpose of blocking sediment particles larger than 5 microns and removing chlorine, which both cause damage to the inside of the RO membrane in different ways:- Sediment particles physically damage the fine internals, causing micro-tears that allow contaminants through to the "clean" side of the osmotic membrane, as well as blocking up the membrane which can cause the system to stop producing water and force an excessive amount of water to waste.
- Chlorine that has been dissolved in water creates corrosive hypochlorous and hydrochloric acids, which dissolve the delicate RO membrane (via a process called "ring chlorination" which disrupts the hydrogen bonding between the membrane's polymer matrix) and allows contaminants to pass through to the "clean side". Because this process occurs gradually over time, most people don't notice the taste of contamination until they change their membrane!
-
Reverse Osmosis Membranes*
Reverse Osmosis membranes filter down to an ultra-fine level of filtration - down to 0.0001 of a micron - which is the reason why RO membranes can filter out minerals, salts, and metals (unlike carbon). Because this level of filtration is so fine, RO membranes do eventually clog up over time. How long you will be able to get out of your RO membrane, depends on the consistency of your membrane pre-filter maintenance, along with the starting quality of your water.

-
- HARD WATER (water that is full of salts and minerals) takes a bigger toll on RO membranes than water that is SOFT (water with a low Total Dissolved Solids rating).
- Western Australia, South Australia, the Northern Territory and Queensland tend to have hard water, along with those whose main source of water comes from a bore.
- Thus, whilst we have specified a recommended maintenance schedule (below), the quality of the water in the area you live, is ultimately what will determine how long you get out of your RO membrane.
- *If you are on hard water, at the 2-year mark, simply go for the FULL Replacement Pack (which includes an RO Membrane). Note - cases of extremely hard water may get less than 2 years out of an RO membrane.
-
Post-Filters
This is the filter that goes after the RO membrane to "perfect" the water for final use.

Why is the storage tank necessary?
Reverse Osmosis Water Filtration is a slow process where water is forced under pressure, through a membrane wall at 0.0001 Microns. This process cuts the water production back to anywhere between 8 and 10 Litres per hour. The Reverse Osmosis Storage Tank is used to store this filtered water so that when you open up the tap on the sink, you have water on demand for drinking.
What happens when the storage tank is full?
When the storage tank reaches capacity, it triggers a backflow shut off valve located on the back of the system. This valve actively shuts off the incoming water (from the mains inlet). When you then open the tap on the sink, the storage tank will evacuate the pre-filtered water. The shut off valve will then disengage and begin to top up the tank to capacity once more.
How often do I need to change the filters?
As a general rule with RO systems, the first 2 filters (Or pre-Filter) should be replaced strictly every 6 months. This is highly recommended to help prolong the life of the more expensive and important Reverse Osmosis Membrane. If a pre filter is left on for too long, as the efficiency of chemical reduction is reduced, it may begin to let through residual traces of Chlorine through to the membrane. The Reverse Osmosis membrane is susceptible to damage from any number of chemicals that it comes into contact with, thus would begin to deteriorate more rapidly, potentially causing you to replace your membrane prematurely. Undersink models can have varying configurations but on average, all post membrane filters should be changed every 1-2 years.
What is filter protection equipment, and do I need to use it?
Filter Protection Equipment is an important part of water filtration. Our products are sourced from experienced and reliable manufacturers and also carry the highest level of certification in the water filtration industry. Regardless of Brand, Make, Model or Country of manufacture, water filtration will ALWAYS be the weakest point in your plumbing. The three main causes of water filtration failure are; Overnight pressure surges, Intense Water Hammer Pressure Impacts, and thermal expansion. All of which can be addressed and prevented with a few simple pieces of equipment. A Pressure Limiting Valve is used to buffer the incoming pressure to the Australian Regulation Pressure of 500kPA. This is the minimum requirement for most insurance and warranty validation and is essential when used on Town mains / municipal water. A Water Hammer Arrestor is a copper tube looking device which is commonly found in the laundry (If you have one). It acts to absorb and dissipate pressure spikes in your water lines. Pressure spikes occur from appliances such as the washing machine or dishwasher and can magnify the water pressure tenfold which can cause serious damage to water filtration components. Water hammer gets the name by the distinct sound you hear when the shockwaves rattle loose copper pipes or worn out valves. This is something that is essential to be addressed immediately before installing water filtration. A Pressure Relief Valve is as it sounds. It is pre-set to open once the pressure reaches 110PSI, shooting that pressure/water down the drain line and easing the pressure in your water filter. This is a requirement if you intend to hook up your water filter to a fridge, chiller or ice maker. They are also a good idea to help relieve residual pressure from pressure surges (even if you have a PLV + water hammer arrestor).
What is re-mineralising and is it necessary?
Re-Mineralising or Alkalising are common terms you will hear when reading about Reverse Osmosis. Many sellers will provide you with a song and dance using big words and sales pitches to the point when “you don’t know what it does, but it sounds good”. To put it all into simple terms; The act of re-mineralising or alkalising is simply Raising the pH from an acidic state to a neutral or alkaline state. This is achieved by using a calcite or magnesium based media filter that slowly dissolves trace amounts of inorganics into the water to raise the pH so that it is suitable and recommended for drinking.
Can I install my Water Filter on my own or do I need a Plumber?
For quality assurance and Insurance reasons, we always recommend using a licenced plumber who is familiar with water filtration. This ensures that the installation runs smoothly and is professional.
