Filter System Stage Breakdown

Stage 1: Polyspun Sediment Cartridge – Replace Every 6 Months

These economical "FSA" sediment cartridges are constructed from polypropylene which is spun and melted simultaneously. This technique means there is no centre core to restrict filter performance.  The "FSA" series of sediment filters are compatible with most liquids and are highly effective for sediment, rust, sand, silt, and algae removal. FSA performance sediment filters have no chemical residuals.  They are extremely high performing, and carry a heavy load of sediment before requiring replacement. We choose to use these sediment filters over all other types due to the high performance, high flow rate, high load capacity, and their inability to grow bacterial slime.

Stage 2: 100% Coconut Carbon Block Water Filter – Replace every 6 months

Many inexperienced sellers of RO systems offer a sediment filter in this position. This is a pure waste of money. These systems are primarily used on town water so after the sediment pre-filter, the most important filter should always be a Carbon Filter to protect the life of the membrane.  The carbon block cartridge will remove any larger components but more importantly, will stop chemicals from reaching the membrane. This should then prolong your membrane life (the membrane is your most expensive and crucial component) for a life of up to 5 years (depending on location/water).

Stage 3: Asprin USA Made Reverse Osmosis Membrane – 1-5 Year Life

The RO membrane is the "engine room" of your R/O. All the crucial work is done here, so all the filters before the membrane are primarily there to protect the membrane.  This membrane is a 0.0001-micron rating. It is classed by the manufacturer to be a U.S 50 gallon per day membrane (190 Litres).

Stage 4: GT6-0 Alk Cartridge – Replace every 12 Months (4,000L)

This Filter is made up of Pure USA Magnesium Oxide which provides the highest absorpton of mineral content into the water over a 12 month period. The pH ranging from 9.5 (while new) and decreasing to around 8pH at the end of the filters life. This is a tried and tested cartridge that we have used in our 7 stage for over 4 years.

Stage 5: 100% Activated Coconut Carbon Filter – Replace every 12 Months

Extremely high grade coconut carbon cartridge for maximum extraction of taste or odour issues. This is the same High Quality post carbon filter used in our Watermarked 4 Stage RO system. It provides clean, crisp tasting water. It also has a multitude of uses as an inline carbon filter.

Our Thoughts on Fluoride

Fluoride is a hot topic all across Australia and the entire world. Unfortunately, whether or not you agree or disagree with the Fluoridation of Drinking Water, it is there!

Reverse Osmosis Water Filtration is the safest and most effective solution to remove Fluoride from your drinking water. Fluoride is a proven neurotoxin shown in countless credible studies in the US. The claimed dental health benefits are irrelevant compared to the known and proven correlation between fluoridated water and Chronic Disease.

Reverse Osmosis water filtration is able to remove Fluoride from the water as it is a Mineral Salt. Mineral salts will pass straight through standard filtration however the 0.0001 Micron RO membranes are able to remove Fluoride along with other impurities in the water.

The Misconception of “Re-Mineralising & Alkalising”

Reverse Osmosis water filtration comes with an ongoing debate in regards to the statements “RO water is too pure” and “RO removes minerals that are beneficial and essential for health” Both of these statements are deceptive and to the everyday person sounds like fact, but please let us explain both of these statements. The misconception being water that is “Too Pure” is all to do with the pH of the water (although the “experts” will state things much more dramatically). Water that is “too pure” simply is water that contains little to no minerals and impurities. However, this can leave the water acidic which is not ideal for drinking. The solution, use an alkalising or pH neutralising filter. This is where the word "valuable minerals" has crept into the selling of Reverse Osmosis filtration by sellers that are not equipped with the appropriate knowledge.  In fact, minerals are only valuable when they are IN our bodies, and the way they get there is through organic food intake - not inorganically. Water Filtration uses Inorganic methods, so any mention of "re-mineralizing" the water through water filtration is simply not a process that is benefiting our bodies at all. More of which will be explained later.  A study in the US (which cost manufacturers many millions of dollars) showed a massive increase in total dissolved solids (TDS) in patients’ urine, when drinking water with a pH of below 7 (i.e. acidic water).  The two main culprits for water having a pH of lower than 7 are:  1. Reverse Osmosis  2. Water Distillers for drinking water  Other substances causing a low pH are soft drinks and alcohol.  Once minerals are extracted from water, the chemistry of water adjusts violently to become acidic. This happens because the buffers in the water that generally act to prevent this adjustment have been removed.  An interesting fact is that rain water that is near pure is also very acidic until it reaches the ground – once it reaches the ground it begins to dissolve minerals from the earth, this in turn balances the pH (the chemistry of the water).  Many very clean catchments such as roof tops and clean gutters, first flush diverters and poly tanks are extremely good at keeping water clean - however a trade-off for this is that the water could and most often does remain acidic.  If you have a dirty roof or a contaminated tank, the pH will rise and no longer be aggressive (acidic) but at a price – such as through other peripheral problems like fermentation of organics etc.  Back onto the topic at hand, it’s important that we make a stand and explain that there are no such thing as valuable minerals in drinking water unless they are organic, and organic materials are generally not used for correcting low pH water.  Almost all (barring a couple of exotic and expensive alternatives) pH Neutralising cartridges are made from inorganic material like rock (commonly known as mineral stones).  These inorganic materials release either calcium or magnesium into the water, however these types of minerals are inorganic, not organic - so it's difficult for the body to absorb them or make any use of them at all.  So, in a nut shell, the words 'valuable minerals' is not relevant to post RO pH correction.  Filter Systems Australia does not deal in myths and magic. There are people selling all sorts of "living water products", with all sorts of mythical results, but consider this:  The body needs hydration plain and simple. Now that is pure logic - not sales talk. The best form of hydration is clean, chemical free and impurity free H2O. Exactly as nature intended.  However, a down side to producing this sort of water is that stripping the water as we do, causes the water to become acidic again (back to its rain water condition). So, what's needed at this point is a trade-off...  To produce non-acidic water we need to add back some mineral, this is where the misconception arises. These are non-organic minerals, therefore not valuable to your bodies health, but valuable in the fact that it's achieving a balanced pH - which is vital to your health.

With all of this said, we have once again taken things a step further by producing a system that ticks all the health boxes. You get High Alkaline Water, Hydrogen Rich Water, Chemical and Toxin Free, Fluoride Free, Great tasting water.

**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. 

Australian Water Hardness Map Guide

  • Post-Filters

These are all filters that go after the RO membrane to buffer the pH back up from an acidic state to an alkaline state, and "perfect" the water for final consumption. Over the course of a year, the diffusion of the alkalising minerals into the water will significantly diminish, whilst the carbon post-filter will eventually exhaust its capacity to adsorb residuals.

***IMPORTANT INFORMATION ABOUT WATER SANITATION FOR RAIN/BORE WATER SOURCES***

PLEASE NOTE: REVERSE OSMOSIS SYSTEMS PERFORM OPTIMALLY ON CHLORINATED (MAINS/TOWN) WATER, AS THE PRESENCE OF CHLORINE KILLS THE BACTERIA/FUNGI/YEAST. THEREFORE, REGULAR & CONSISTENT WATER DISINFECTION IS STRONGLY RECOMMENDED FOR RAIN/TANK/POTABLE BORE WATER* SOURCES PRIOR TO USING A REVERSE OSMOSIS FILTER SYSTEM. FAILURE TO ADEQUATELY DISINFECT THE WATER WILL RESULT IN BIOFOULING OF THE RO MEMBRANE (I.E. A BACTERIA/FUNGUS/SLIME COLONY WILL START GROWING INSIDE THE MEMBRANE WHICH WILL PUTREFY YOUR FILTER SYSTEM & RENDER THE RO MEMBRANE UNSALVAGEABLE). 

For Protection Against Bacteria/Fungi/Yeast

Bacteria (such as E.Coli) can colonize in the stagnant water and result in harmful illnesses when consumed. For sanitation against common water-borne bacteria/viruses in rainwater and potable bore water*, we, therefore, recommend dosing your tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser to ensure protection against microbiological contamination/biofouling in your pipework and/or filter system.

HydroSil is a food-grade silver-activated, hydrogen-peroxide based water sanitiser, which acts to oxidise bacteria, yeast, fungi & viruses, without leaving any dangerous residues behind. HydroSil sanitizes and protects your tanks and water storage devices, making rainwater and potable bore water safe and suitable for human consumption. HydroSil is not a chlorine-based chemical like most sterilisers on the market today. It is non-toxic, and safe to use around your home and family.

Dosage Rate: HydroSil should be dosed at a rate of 200mL per 1000L of water. To scale down to tank size, you will require 20mL per 100L.

About Rain Water

Australia is the world’s driest inhabited continent, and an astonishing 10% of Aussies don’t have access to a mains water supply, so it’s no wonder why rainwater and bore storage tanks are so popular in rural areas to save water during drought and for household use all year round in cooking, cleaning, gardening, bathing and sometimes even drinking. However, whilst many people enjoy the sweet taste of rain and spring water, and some even swear by the ‘raw water’ trend (which proponents (sometimes falsely) believe has more minerals and fewer contaminants than regular chlorinated town water), we cannot stress enough that drinking untreated water is a very bad idea!

Scarily, in Australia, the general public perception is that rainwater is pure, clean, and safe to drink, but according to the Australian Environmental Health committee’s Guidance of the Use of Rainwater tanks, the fact is that the microbial quality of tank-collected rainwater is typically worse than regular urban tap water, and not to mention, the chemical quality of rainwater can be negatively impacted for those living near heavy industry or in areas with heavy traffic emissions. For example, rainwater samples in Port Pirie, South Australia, (which has one of the world’s largest lead smelters), have been found to contain levels of lead that exceed Australian Drinking Water Guidelines by up to ten times! Even bushfire can contaminate rainwater! And that’s not to mention the microbiologically sickening soup of bacteria, viruses parasites that inevitably make their way into your tank from disease-spreading insects such as mosquitoes, the excrement and decaying carcasses of frogs, snakes, rodents, and possums that commonly live in and around tanks, and the droppings from bats and birds flying overhead! Also consider that bacteria tend to proliferate in moist and warm environments, meaning that warmer weather, in particular, has the tendency to turn your tank into a putrified bacterial breeding ground. Thus, whilst rainwater may smell odourless, taste great, and look clean and clear to the naked eye, with the human senses alone, you simply cannot tell what potentially harmful microscopic contaminants could be lurking in your tank water (even after filtering the water with carbon) – and you certainly don’t want to be drinking it!

About Bore Water

Bore water will always require filtration, as whilst you would think it is “naturally purified” to some extent as the water seeps through the aquifer via various layers of bedrock, this water is highly susceptible to contamination by bacteria, viruses, parasites (see: Brain-Eating Parasites), sewerage (think human excrement, cleaning and bathing products), chemicals, fertilisers, pesticides, minerals, heavy metals (such as lead, zinc, chromium, copper, cadmium, arsenic and nickel), and sometimes even radioactive elements (such as uranium) from both natural sources and human activity. As with rainwater treatment, the most cost-effective solution is typically to use 5 Micron Carbon Filtration in combination with UV Sterilisation to ensure 99.9% eradication of all parasites, bacteria, viruses. However, this system is not always a "total fix", as bore water chemistry is incredibly complex, and sometimes may not even be treatable. Yet another common misconception we often encounter is that carbon can filter out anything and everything – but unfortunately, carbon doesn’t kill bacteria or remove minerals, salts and other such dissolved inorganic substances!

We STRONGLY recommend that you get your bore water tested to determine if there are any underlying issues in the water chemistry of your bore, before you make any purchases or try to filter it. If you have not had your water tested yet and would like to get this done, please contact us to have your bore water analysed.
