Items Included In Kit

  • GT1-4WM 10" x 2.5" Heavy Duty Twin Filter System with your choice of filters - For clarifying the water whilst improving the taste.
  • GT7-4K Ultraviolet Sanitation System - For sanitising water - kills 99.9% of bacteria, parasites, and viruses.

Rain Tank water will always require filtration as it isn't treated like municipal water supplies. In our experience, the most cost-effective and total solution is to use UV Sterilisation, which will ensure 99.9% eradication of all Bacteria, Parasites, and Viruses from your house water supply.


This system is designed to handle water flow with an average household pressure pump system up to 500 kPa (72 psi), so you should not notice any significant reduction in pressure during regular water usage for a small household with a decent pump. Please note: around 344kPa (50 psi) is the ideal minimum pressure required for use with this system - pump pressures lower than 275kPa (40 psi) may cause excessive pressure drop if installed alongside a whole house filtration system (i.e. low water pressure in showers).


This system is WaterMark Certified to Australian Plumbing Standards (AS/NZS 3497), and will need to be installed by a licensed plumber. Simply order online with free shipping to your home, and once it arrives any local licensed plumber will be able to do the installation (the system also comes with instructions)! When calling around for quotes, be sure to ask about installing a "bypass" so you can still get water into your home when the time comes for filter changes! Normally, a whole house system will be installed after the pump and before the main water line goes into your property. Your plumber will need to source fittings to install the system to your required specifications - because all setups are different, we do not supply fittings with this kit. Please refer to the description for items supplied with this kit. As the blue housing is UV resistant it can be installed in direct sunlight, however, installing the system in the shade or under cover can help prolong the life of the housings. Please note that the UV System (including the Stainless Steel Chamber + Power Supply) is not waterproof and should be protected from the weather/rain/water/moisture at all times. The UV System must also be installed directly into a single socket surge protector before being connected to a 240V 10A General Power Outlet (PowerPoint). It must be a surge protector - Circuit Breakers and Residual Current Devices (RCDs) are not suitable substitutes as they do not protect the unit from power surges. All aspects of this Water Filtration + UV System Kit must be protected from freezing temperatures at all times.


All Water Filtration Systems included in this package are certified to WaterMark Standards AS/NZS 3497 under Certificate number 23247. WaterMark is the standard that is required by law for a qualified plumber in Australia to install any item on municipal town water. All products used under this certification will give you peace of mind knowing that your water filter complies with Australian plumbing codes. Our WaterMark filtration systems are hand assembled here in Australia and are batch tested to ensure quality and workmanship for your filtration products.

How can you tell if a flow rate of up to 15 Litres Per Minute of water flow is suitable for your needs? Please see the below infographic:

If you have any questions at all regarding the compatibility, installation, items included with each kit, or the added extras, please contact us prior to purchasing.


Heavy Duty Twin Outdoor Caravan Water Filter System | White Bracket | WaterMark Certified (GT1-4WMW)


The Twin 10" x 2.5" Heavy Duty Caravan Filtration System houses a Sediment cartridge for improved water clarity and protection against particulate matter damage within the UV System, and a Coconut Carbon cartridge to reduce tastes/odours, and impart a subtly-sweet flavour into the filtered water. Please Note: Even though the UV System that comes with this kit is capable of filtration at 30 Litres Per Minute, the flow rate capacity of the entire filtration system is limited to 15 Litres Per Minute due to the 10" x 2.5" sized filter housing.

Kit Includes:

  • Twin 10" x 2.5" Caravan Filter System (Pre-Installed Bracket)
  • Opening Spanner
  • Instruction/Warranty Sheet
  • Your Choice Of Filters (Additional Charges Apply)

Specifications & Technical Data:

  • Dimensions:
    • Height: 36.5cm
    • Width: 28cm
    • Depth: 16.5cm
  • Filter Cartridge Size: 10" x 2.5"
  • Ports: 3/4" Female BSP Inlet/Outlet Ports
  • Pressure: 0 - 620 kPa
  • Limit Pressure: ≤ 500 kPa
  • Temperature: 0.5°C - 37.8°C
  • Max Flow: 15 Ltrs/min (*Maximum flow must not exceed 30 Ltrs/min. Flow measured without cartridge. Refer to cartridge specs for flow rates.)


  • FILTER SIZE - The 10" x 2.5" size of system is ideal for low water usage scenarios (i.e. 1-2 people max) who are extremely conscious of how much water they use, and don't mind being limited to using one or two appliances at a time ie. taking a shower and not using the dishwasher at the same time). Water pressure problems can occur by selecting too small a system. 
  • FILTER CHANGES AND MAINTENANCE - Since this system is quite small, we recommended filter changes on a 3-6 Monthly basis, and offer a filter reminder email service to help you remember! Simply email info@filtersystemsaustralia.com.au when you place your order, and ask us to set you up with a filter reminder on the basis that you prefer! Filter changes are easy enough – simply turn off the water going into the system, press down on the pressure relief valves, unscrew the sumps, replace the filters, screw it back up and turn the water back on! You may notice the water feels a bit "slippery" at first after installing new filters, but don't worry - this is normal and will go away quickly once enough water has run through the new filters. Also, if the water looks cloudy at first, again - don't stress! This is dissolved oxygen and it will go away quickly once enough water has run through the new filters.

Filter Options

Customise your filter system set up to suit your unique needs. Please read the below for a full breakdown of which filters to choose, and why*.

*Please note - the below recommendations are general information only and may not always suit your requirements. Please call us on 07 5597 4585 prior to purchase if you have any questions about your requirements.

Sediment Filters

  • Choose from pleated (washable) or polyspun (disposable) sediment filters. 
  • 5 Micron is well suited for mains/town-treated water and high-quality rain/tank water.
  • If you get a lot of sediment (typically on tank water***), consider upgrading to a Triple Whole House UV Sterilisation System which allows you to place a pleated filter first, followed by a poly spun with a final carbon element. 

Tank water is often contaminated with sticks, leaves, and rock sediment. In some cases, finely dissolved matter can even cause visible discolouration, build-up and staining, along with a foul taste and odour - and even a gritty texture in some rare cases! Installing a sediment filter also helps protect your pipes and carbon filters from getting blocked up with ultra-fine silt, whilst also preventing damage to the glass internals of the UV system.


Pleated (Washable/Reusable) Sediment Filters

  • Larger Surface Area Catches More Debris
  • Reusable/Washable
  • Ideal Pre-Filter for Tank Water**

Pleated filters carry a much larger surface area than polyspun filters, and therefore they are able to catch a lot more debris. Simply remove the filter, clean, and re-use! Very popular for tank water when you have a lot of debris like leaves and dirt, particularly after a fresh rain. The washable pleats on this filter are designed to be washed and reinstalled. However, please consider that if this is drinking water you need to be careful not to overuse a pleated filter, because it will eventually gather bacterial contaminants and incur micro-tears. If the water isn't all that bad you might want to consider using a polyspun disposable filter and replace it when dirty. 

Pleated Filter Options:

  • 5 Micron Pleated Washable Sediment Filter Cartridge

Poly Spun (Polypropylene) Disposable Sediment Filters

  • High Flow & Low Pressure Drop
  • Cost-Effective & Disposable

Poly Spun filters produce a high flow and low pressure drop, and do not accumulate bacteria as much as other materials. They are highly cost-effective and disposable. All of our poly spun filters are made of 100% Virgin Polypropylene. Polyspun filters are manufactured to create a gradient density that allows for excellent sediment-holding capacity and filtration efficiency.

Polyspun Filter Options:

  • 5 Micron Polyspun Sediment Filter Cartridge

Pure Brand 100% Coconut Carbon Filters

  • High Quality, 100% Coconut Shell Carbon that Produces "Sweet" Tasting Water
  • Excellent Contaminant Reduction Capacity for Common Chemical Health & Aesthetic issues such as Chlorine, Trihalomethanes, Volatile Organic Compounds, Pesticides, Herbicides, Tastes & Odours.
  • Recommended 12 Month Lifespan if (used on Municipal Treated Water - you may get less if used on particularly dirty/turbid/raw water).
  • Designed for Minimum Impact on Water Pressure

The perfect carbon block filter is made from 100% Coconut Shell Carbon, which creates what many believe to be the sweetest tasting water. The unique pore structure of this carbon is well suited for chemical absorption, including VOC's, while reducing chlorine and chemicals that contribute to taste and odour. Coconut Carbon provides a much higher volume of micropores than coal, wood, or lignite-based carbon, thus, resulting in a more effective removal of chemical contaminants such as trihalomethanes (THMs) in Chlorinated sources. The larger surface area provides a more effective method of filtering common contaminants such as chlorine, tastes and odour molecules. The unique raw material of the coconut shell and the carbon manufacturing process ensures exceptional hardness and low ash content.

Pure Brand's 100% Coconut Carbon Block Filters are made from a combination of high-performance coconut shell carbon, unique binders, and industry-leading manufacturing processes to deliver supreme-quality filtration. Expertly designed and manufactured, these filters deliver exceptionally low-pressure drop, resistance to sediment build-up, and excellent contaminant-reduction capabilities. Pure Carbon Blocks are registered in compliance with NSF/ANSI 42, 53, and 61 for several things, including VOCs, THMs, Lead & Heavy Metal Reduction, Chloramine Reduction & Chlorine Taste & Odour reduction. This also includes meeting incredibly high standards of purity and safety in the materials used.

Please see below for a full comparison of our range of Carbon Filters recommended for use on Rain/Tank*** Water:

GT4-7CTO - 5 Micron Chlorine Taste & Odour Reduction Coconut Carbon (Budget Option for Improved Chlorine Taste & Odour Reduction in Tank Water)

  • CTO Carbon is our standard recommendation for chlorine reduction, improved sweet taste and reduced odour - great value and quality!

Chlorine is generally the biggest concern for those on municipal water or those who use chlorine to disinfect their tanks, due to the offensive chemical smell and taste it produces, along with potential health effects resulting from topical exposure or consumption. Whilst Chlorine is effective at sanitising bacteria and viruses, Volatile Organic Compounds and Disinfection By-Products such as Trihalomethanes (THM) and Chloroform can form when chlorine reacts with oxygen and other chemicals in solution. The Chlorine, Taste, and Odour cartridge will provide you with clean, great-tasting water free from nasty chemicals and remove or reduce any chemical smells in the water caused by free chlorine.

Rain/Tank Water** Filter Combo Example*:

Filter 1: 5 Micron Pleated OR 5 Micron Poly Spun Sediment Filter
Filter 2: 5 Micron CTO Carbon 
Filter 3: Ultraviolet Treatment


GT4-58BCC - 5 Micron Bacteriostatic (Silver Impregnated) Coconut Carbon Block (For Preventing Filter Biofouling in Raw/Tank/Rain** Water)

  • Ideal for Pre-Filtering tank** & Raw Water Prior to Ultraviolet Treatment.
  • Prevents Bacteria from Proliferating within the Cartridge.
It's important to note that Silver Impregnated Carbon is BACTERIOSTATIC - meaning that it inhibits or prevents the increase or growth of bacterial levels WITHIN the filter only. Silver Impregnated/Bacteriostatic Filters DO NOT sanitise, disinfect or remove bacteria from water. If this is your goal, further treatment is required - please refer to the note at the bottom of this page **FILTERING TANK AND BORE WATER - IMPORTANT INFORMATION BEFORE YOU ORDER**.
Contrary to popular belief, carbon does not filter out bacteria. Whilst carbon effectively removes odours and taste issues from water, carbon ash is actually a source of nourishment for bacteria, making wet carbon filters a breeding ground for microbial contamination (Note: this should not be an issue on mains water as Chlorination is designed to kill bacteria). This, unfortunately, causes biofouling of the filter cartridge which can lead to premature blockage (costing you hundreds of dollars to replace cartridges more frequently than you should have to), putrid tastes and odours and worse - illness as a result of ingesting the bacteria that has passed through the cartridge and into your drinking water! Using a rotten filter can make you seriously sick - so if in doubt - chuck it out!
Silver Impregnated Carbon, on the other hand, is bacteriostatic - meaning that it is proven to inhibit the growth of carbon-fed bacteria within the filter to prevent bio-fouling and prolong the life of a cartridge - even while it is not being used! Therefore, when it comes to filtering raw water, Bacteriostatic (Silver Impregnated) Coconut Carbon is the number one choice, as this media is specifically designed for use with rainwater and tanks to prevent bacteria from breeding and colonising within the carbon and extending the life of your filter. Silver Impregnated Carbon is ideal for periods of time where the filter may go unused. If you want to get the most out of your carbon filter, you can even go one step further and dry it out between uses! 

So, how does Silver Impregnation inhibit the growth of bacteria in a carbon filter? When bacteria come into contact with silver, the silver ions puncture the bacteria's cell membrane and wreak havoc by binding to and denaturing the bacteria's DNA. The sulphydryl group already within the bacterial cell also reacts with the silver, producing a silver sulphur complex that immobilises the respiratory and reproductive activity of the bacterial cell. Interestingly, Silver Impregnation has an incredibly long-lasting effect, as the dead bacteria then leach the silver molecules back into their environment, effectively killing neighbouring live bacteria as they die.

Dead bacteria store the microscopic silver particles within their cells (see above image of dead bacteria with silver nanoparticles (white spots), making them deadly to live bacteria.

GT4-3LRC - 0.5 Micron Lead Reduction Composite Coconut Carbon (For Chlorine Reduction & Heavy Metal Concerns in Rainwater, Old Infrastructure, Cities & Industrial Areas)

  • Reduction of Chlorine, Tastes, Odours and Heavy Metals.
  • Ideal for Filtering Rain/Tank Water where atmospheric pollution may be of concern.

On the basis of local and atmospheric contamination, it is not uncommon to have elevated heavy metal levels in rainwater supplies. 

Constant exposure to heavy metals combined with the different chemicals being used to treat our water supplies can have serious health effects, and can also cause severe plumbing problems within our homes. Rainwater (acidic pH) and chlorine/chloramine treated water (basic pH) both tend to be quite corrosive, and this can wreak havoc on the internal plumbing and fixtures within old municipalities and even the copper and brass fixtures in your home (which fittings may contain traces of lead)! The chemical quality of rainwater can also 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 heavy metals such as lead that exceed Australian Drinking Water Guidelines by up to ten times! (Even bushfire can contaminate rainwater, in which case you'll need to have your tanks cleaned out!)

This cartridge is perfectly suited to reducing trace heavy metals that may be present in your water. The technologically-advanced Lead Reduction Cartridge is impregnated with BASF ATS Lead and Heavy Metals Adsorbent Media, which features a high capacity for the reduction of Lead and other heavy metals such as Arsenic, Chrome, Copper etc., along with the usual benefits of carbon in the reduction of Chlorine, Volatile Organic Compounds, and Trihalomethanes.

Whilst many people enjoy the sweet taste of rainwater, we cannot stress enough that drinking raw, untreated water from a tank 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!

Raw, untreated water contains a microbiologically sickening soup of bacteria, viruses & parasites that inevitably make their way into your tank from disease-spreading insects such as blood-sucking 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. E.Coli, Salmonella, Legionella & P. Aeruginosa are some of the more common pathogenic bacteria found in rainwater tanks, whilst Cryptosporidium and Giardia Cysts are the most common rainwater tank parasites. All of these pathogens are a common cause of Gastro!

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!

UV Water Sanitation is by far the most important filtration process when it comes to rainwater treatment. Ultraviolet sanitation works by breaking down the cell wall of micro-organisms (bacteria, parasites, viruses, fungi & yeast), allowing oxidation to occur which in turn prevents the microbe from multiplying until it is finally eradicated. Ultraviolet filtration is a chemical-free solution to water sanitation, creating no by-products in the water, and is recommended by the Australian Drinking Water Guidelines as a safe, effective and chemical-free water disinfection technique:

Installation Requirements

  • This appliance must be installed directly into a single socket surge protector before being connected to a 240V 10A General Power Outlet (Power Point). It must be a surge protector - Circuit Breakers and Residual Current Devices (RCDs) are not suitable substitutes as they do not protect the unit from power surges.
  • The GT7-4K UV System is not weatherproof and all components (including the chamber and electronics) must be shielded from direct sunlight and weather extremes such as harsh UV exposure, rain & storms. Looking for a fully enclosed Whole House UV System?  Check out the specially designed High Performance | Weatherproof Twin Filter + UV Whole House Water Sanitation System (HPF-UV):

UV System Maintenence Notes:

Ultraviolet systems are rated based on a dosage level of UV-C radiation into the water (mJ/cm²), with 30mJ/cm² being the standard level of disinfection and a minimum dose of 40mJ/cm² required to comply with the Australian Drinking Water Guidelines. Our lamps are rated with a 9000 hour (1 year) lifespan, after which point the lamp will naturally degrade and the level of radiation produced by the lamp cannot be guaranteed.

The UV lamp sits inside a quartz thimble, which protects the electrical components of the lamp from making contact with the water. We specifically use quartz (fused silica) for this application because it is strong, exhibits thermal resistance, and has excellent UV transmission properties. However, over time, metal ions fused within the silica structure of the quartz thimble interfere with the UV-C radiation produced by the lamp, which reduces the UV transparency of the glass and causes it to become fragile. This process is called solarization. Tannin, bio-film, algae, and scale can also build up on the outside of the glass thimble, further preventing ultraviolet light produced by the lamp from penetrating through the thimble, and impairing the system's ability to sanitise the water passing through. It is recommended to clean the thimble periodically (every 3-6 months with alcohol or a mild detergent.

Thus, we recommend replacing the lamp every 12 months, and the thimble every 1-2 years.

GT7-9K UV System Replacement Parts:


OPTIONAL (RECOMMENDED) ADD ON: HydroSil Ultra 7.5% | Silver Stabilised Hydrogen Peroxide Water Sanitiser

As UV is a point of use (non-residual) form of water sanitation, we strongly recommend dosing your tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser upon installation of your Whole House UV System, to ensure full protection against bacterial and fungal contamination/biofouling/biofilm build-up in your pipework and/or filter system.

HydroSil is a food-grade silver and hydrogen-peroxide based water sanitiser, which acts to oxidise bacteria and fungi without leaving any dangerous residues behind. HydroSil sanitizes and protects your tanks and filtration devices to help make your tank water safe for human consumption. HydroSil is not a chlorine-based chemical like most sterilizers on the market today. It is non-toxic, and safe to use around your home and family.

Dosage Instructions for the Initial Treatment Immediately Prior to System Installation:

  • HydroSil should be dosed at a rate of 200mL (2L) per 1000L (10KL) of tank water.
  • Turn on every tap in the house until you are satisfied that the treated water has passed through.
  • Immediately install the Whole House System.
  • It is recommended that this dosing procedure should be completed every time the UV lamp is changed.



**Why UV Disinfection is NOT Recommended for Travelling in Caravans/Casual Use**

You may have read that Ultraviolet (UV) Disinfection is one of the safest and most effective methods for treating drinking water, as it has a minimal effect on drinking water’s composition and taste, whilst killing 99.9% of microbiological contaminants. It's true that UV is highly effective at inactivating the DNA cells of water-borne micro-organisms such as bacteria and viruses, and is excellent at killing chlorine-resistant parasites such as Giardia and Cryptosporidium.

However, as effective as they are, please note that UV systems are generally NOT recommended for caravanning and casual use, for the following reasons:

  • UV Systems require electrical input and typically need to be left on 24/7 to prevent degradation of the UV lamp (not ideal for infrequent use).
  • UV radiation also heats up the UV chamber and, in some cases, requires a constant flow of fresh water and a thermal release valve to release the hot water (which is not ideal on a small water tank).
  • UV Systems also contain fragile glass components (not ideal for travelling).

Provided the system is stored out of the weather and stationary (i.e. in Stationary Home Caravan or Cabin), then UV is suitable. 





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.
