Ultimate caravan water filter and purification kit.


A complete caravan water filter and purification system. A pre-filter to fill your van and a purifier to purify your drinking water – all contained within two compact light weight filters. Our Bore Water & 5-micron Sediment tank fill pre-filter will treat bore water – improving taste and reducing mineralisation of pipes and appliances. Protect your tanks from sediment, algae & fines and then install the Thirsty Nomad 5 in 1 purifier in your van to purify your drinking water to Australian Drinking Water Standards for e.Coli. Tested, verified and proven. Have a look at our independent laboratory results for yourself. FILL YOUR VAN with the Sediment & Bore Water pre-filter then purify your drinking water with our point of use dedicated drinking water purifer. Please note, do not purify all the water in your van, our purifier is designed to be used as a dedicated drinking and cooking water purifier installed onto a single dedicated cold water line – after the hot water junction and onto a dedicated cold water line as close to possible to your dedicated drinking and cooking water tap. 

It is now easier than ever to purify the water you drink and cook with in your caravan. Easy to install and use, our 5 in 1 caravan water filter that purifies water by completely destroying harmful bacteria and viruses at the cellular level, upon contact. All tested to AS/NZS Standard 4276.7 Water Microbiology and meeting NSF Protocol 231 for Water Disinfection for your trust and peace of mind. This is a highly designed, high performance purifier that is designed to be used as a DEDICATED DRINKING WATER PURIFIER IN A DEDICATED COLD WATER DRINKING WATER LINE INSTALLED INLINE AFTER A 55PSI PUMP. THIS IS A HIGHLY ENGINEERED PURIFIER AND NOT TO BE USED TO FILL TANKS WITH – THAT IS WHAT OUR BORE WATER & SEDIMENT FILTER IS DESIGNED FOR. Our purifier is optimally used when installed inside your van, after a 55 PSI caravan pump into a dedicated cold water line, as close to your drinking and cooking water tap as possible. 

You can now turn the water in any river or creek you encounter into safe drinking water with our highly versatile and easy to use portable water pump and purification kit. Comes complete with both 12V or 240V charging options. It is capable of purifying 100 litres in as little as 25 minutes with the flick of a switch – all contained within a compact lightweight (5.7kg) carry box. Take our portable water purifier down to the creek’s edge and start purifying clear creek water into safe drinking water. 

Fill your van’s tanks with the right type of filter. Fill with confidence using our Bore Water & Sediment Filter. Not only does it treat the minerals most commonly found in Australian bore water, it will also reduce the sediment, silt and dust in your tank, which is a perfect breeding ground for harmful pathogens. The first stage of any quality water purification system is sediment removal and common granular activated carbon filters are not the right type of filter for stage 1 filtration and they will quickly clog with the minerals found in bore water. Granular Actived Carbon filters will not remove sediment and they cannot treat bore water mineralisation – The Thirsty Nomad Bore Water & 1 micron sediment pre-filter will keep your tanks clean from sediment and keep your purifier free from clogging due to bore water mineralisation.

The Complete Caravan Water Filter system. Inside & Out.

Our scientific water filter caravan systems are the only caravan water filter purifiers proven to Australian & New Zealand standard 4276.7 Water Microbiology to eliminate e.Coli to Australian Drinking Water Guidelines for e.Coli.  Sediment removal is always the first stage of a sophisticated and effective water purification system.

The Thirsty Nomad Bore Water & 1-micron Sediment Pre-Filter is the right type of filter to fill your tanks with. Keep your tanks free from sediment and bore water mineralisation and bio-film. 

Commonly available granular activated carbon (GAC) filters  quickly mineralise and clog due to the minerals in bore water and these companies have not thought about the Australian water conditions at all. 

Our bore water media works via an ion-exchange and will reduce the dissolved minerals found in Bore water, protect pipes and applicances and balance minerals to improve taste. With just 2 filters you get a 7 stage mobile caravan water filter treatment system that also purifies

Our 5 in 1 caravan water filter also purifies

Our 5 in 1 Purifying filter works hard on your behalf to make sure that the water in your van is as clean and safe for drinking and cooking as possible. 

Designed by water scientists including the inventor of Quantum Disinfection – Dr Cristian Chis PhD Water Chemistry. 

Please note this is designed as a DEDICATED DRINKING WATER LINE PURIFIER.  When camping there is no need to “purify” all the water in your van, our purifier is designed as a high performance drinking and cooking water purifier. It starts, by removing the heavy metals  while also eliminating the pathogen load via an activated media. 

Bringing you the very latest in carbon technology, our carbon fibre block in our 5 in 1 purifier is designed to remove a high rate of chlorine and chloramines over it’s extensive surface area while also removing heavy metals including Fluoride. Our activated 1 micron media further reduces the pathogen load and removes microplastics. Finally, our 0.001 micron Quantum Disinfection media kills 99.9999% of harmful bacteria & pathogens.

Frequently Asked Questions

It is entirely a personal choice and up to you. Water quality around Australia can be variable and not always consistently treated to municipal water  treatment standards.  With the increase in the shear number of people camping, over development of our rural areas and increased runoff, pollution levels in natural environments have been gradually becomming higher. This is why water filters are invaluable for anyone living or travelling in a caravan or RV, regardless of whether you are staying for a while in a caravan park, travelling from town to town, or you’re going off road and exploring the outback. A caravan water filter is invaluable for those travelling with young children. Why? Children’s immune systems are not fully developed when they are born and typically their immune systems only become fully developed around age 7-8.

A caravan water filter needs to be the right type of filter for the job. And, water purification isn’t a simple “silver bullet”. And, if you want a cheap simple filter just to fill you van tanks then we are not the company for you. To provide safe drinking water caravan water filters need to be both effective as a purifier and compact, light weight, and technologically advanced. The Thirsty Nomad system will enable you to access and use, with confidence, mineralised bore water. With our 12 Volt portable purifier kit, you can purify free flowing water from rivers, creeks and streams. Our specialist range of products feature a Bore Water & 5 micron Sediment Pre-Filter which enables you to safely fill your tanks with bore water, along with a 5 in 1 purifier that can be installed in your caravan or RV to purify the water you use for drinking or cooking. 

It is not uncommon in rural Australian caravan parks to be accessing water from a local potable bore water source. While it can be of high quality, if is properly maintained, groundwater can nevertheless be susceptible to a variety of contaminants, such as industrial pollution, radioactive materials, animal waste or more. 

It is important to understand that those outdated, generic, overpriced Granular Activated Carbon filters (GAC) will mineralise with bore water and do not filter bore water sufficiently for it to be used to fill your tanks with confidence. GAC filters cannot effectively remove sediment, silt, rust and dust – a sediment filter can.  A GAC is not a Stage 1 filter, a sediment pre-filter is. Additionally, CAG filterswill remove the chlorine that you may be provided with, this is wrong, as the chlorine going into your tanks is actually useful as a means of keeping your RV water tanks clean and safe. CAG filters cannot kill bacteria and viruses, nor can silver in a point of use water filter, without very long contact times. 

In contrast, the Thirsty Nomad 5 micron Bore Water and Sediment Pre-Filter is designed specifically to reduce the amount of calcium, magnesium and iron, as well as reduce sediment, silt and dust in bore water. All of which can cause a bio film to form in your tank and harbour harmful pathogens. 

Our 5 micron bore water & sediment pre-filter should be combined with the Thirsty Nomad 5 in 1 Caravan Water Filter & Purifier, designed to produce safe, clean drinking and cooking water for your van. Our 5 in 1 Caravan Water Purifier is engineered, tested, and proven to international and Autralian Standards. The only inline water filter that purifies thanks to the Thirsty Nomad’s 0.001 micron Quantum Disinfection media – providing you with the elimination of 99.9999% of harmful pathogens upon contact.

To answer this question depends on water quality, water volume and filter type. Filters and purifiers are designed to ‘load’ over time, this means they are doing what they are designed to do. No quality water filter will last forever — you will find that any such claim in reality can’t be backed up — however, we want you to get the maxium life out of your Thirsty Nomad “5 in 1”. To get this longevity, we recommend you use your Thirsty Nomad as a dedicated drinking water purifier on a dedicated drinking water line in conjunction with our Bore Water & Sediment pre-filter. 

The carbon particles used in our 5 Micron Carbon Fibre Block technology are between 5 and 20 times smaller than in those outdated GAC filters. The fibres in our Carbon Fibre Block are much more tightly packed, so that even the smallest particles and contaminants are unable to get through (this also means it can continue to remove high levels of chlorine throughout it’s whole operating life). 

You can expect our 5 in 1 Caravan Water Filter & Purifier to effectively filter 7,500 lites of water before it needs to be changed (determined by volume and water quality). It is also possible to backwash your purifier. 

One of the best ways of ensuring that you get maximum operating life and efficiency from your inline water filter for caravan or RV is to make sure you have the right filter for the right job.

That’s why we always recommend that you pair our 5 in 1 purifier with our Bore Water & Sediment Pre-filter. Giving you a 7 stage filtration system in 2 filters. 

Our Bore Water & 5 micron Sediment Pre-filter cartridges will last for approximately 3,500 litres, please note, this too is dependent on water quality and the level of dissolved minerals within the bore water. By using the pre-filter, this will not only protect your purifier so that the purifier lasts longer, but it will also help to protect the appliances in your camper or van from algae, rust, dirt and sediment. 

If you do this, you can expect the filter in your purifier to be able to last for about 7,500 litres (depending on the quality of water it is filtering). When the water flow rate inside of your van starts to show signs of slowing, this is the indicating factor that tells you that it’s time to change your filter. 

It is a straightforward procedure to install a permanent inline water filter for caravan or RV.

The Thirsty Nomad 5 in 1 Purifier should be installed after a 55psi pump (the pressure helps the purifier to perform at optimum level) in either a 16 mm PEX, 12 mm, 8 mm or 6 mm cold water line (ideally a dedicated drinking water line), as this will give you longer operating life. The purifier can be mounted in either a horizontal or vertical position, and if installed after a 55psi pump, you can expect a flow rate of 4-6 litres per minute. We note that some caravan manufacturers are installing pumps that are lower than 55psi – our purifier will work with as low as 40psi pumps but the water flow rate will drop. 

To make installation easier for you, the 5 in 1 permanent option comes complete with simple push fittings that mean it is the work of a moment to connect, including:

  • 2 x ¼” (6 mm) BSP push fittings
  • 2 x ½” (12 mm) BSP push fittings
  • 2 x 1/2″ BSP male lead free brass fittings
  • Set of mounting clips

The 2 x 1/2″ BSP male lead free brass fittings will fit most standard connections, including braided hoses with two female ends. 

The fact that all the brass connections in our caravan water filter kit are lead free is very important.  The fittings on some line water products are not guaranteed to be lead free, which means that over time trace amounts of dead could potentially leak into the drinking water in your caravan. This is potentially very harmful, so we remove the risk by ensuring there is no lead in any of our brass connectors.

The Thirsty Nomad 5 in 1 Caravan Water Filter is also a Caravan Water Purifier. Our exclusive Quantum Disinfection™ media, has been independently certified by over 14 laboratories to kill 99.9999% of bacteria, viruses in line with Australian Drinking Water Guidelines for e.Coli. Our purifier has been independently tested to Australian Water Microbiology testing standards to achieve “zero” e.Coli content.  Additionally, our caravan water filter meets the internationally recognised NSF P231 Protocol for water disinfection. Designed in Australia by Australians, the Thirsty Nomad has an International Process Patent lodged with IP Australia. 

Our exclusive Quantum Disinfection™ media is odourless, high purity and environmentally friendly, as it is a solid ceramic, alumina based insoluble activated media. It is able to eliminate 99.9999% of pathogens within 0.1/second via a catalytic reaction and does not leach anything into the water. Quantum Disinfection media is 0.01 micron equivalent rated. This is 100 times finer than any other inline caravan water filter system on the market, and is why it is able to purify water so effectively.
