The Thirsty Nomad

Complete Caravan Water Filters
Bore water filtration & water purification - in 2 easy steps.
Bacterial Elimination - Proven to AU/NZS Standards.

100% Australian Designed, Owned & Operated, the Thirsty Nomad are caravan water filters – independently proven to purify. The Thirsty Nomad has been engineered by water scientists. When travelling Australia, you may encounter highly mineralised Bore Water. Bore Water will quickly mineralise (clog) those standard granular activated carbon filters which cannot kill bacteria upon contact. 

The Thirsty Nomad caravan water filters, that also purify, provide you a means to treat mineralised bore water and then purify your water (eliminate 99.9999% of harmful pathogens) with two filters providing you a seven stage complete caravan water filtration & purification system. 

 Your caravan water filter should be…

    • a purifier as well as a filter
    • not falsely advertise the use of silver to kill bacteria – silver cannot eliminate bacteria to safe drinking levels without very long contact times
    • designed to reduce mineralised bore water that will clog those generic granular activated carbon filters
    • designed by water scientists
    • be the right type of filter for right job
    • be proven and tested for microbiological elimination to AS/NZS Standard 4276.7 Water Microbiology
    • meet Australia Drinking Water Guidelines for e.Coli  – which is zero. 
    • be the latest in water disinfection technology, not a simple filter that has not advanced in over 20 years.
    • be the latest in carbon fibre which has a greater surface are than granular activated carbon
    • able to kill 99.9999% of harmful bacteria and viruses in 0.1/second as per international water disinfection requirements.
    • filter down to 0.1 micron – 10 times finer than 1 micron
    • certified to NSF/ANSI Standard 61
    • Certified to NSF/ANSI Standard 42
    • Certified to meet NSF Protocol 231  – confirming 99.9999% of bacteria & virus elimination in 0.1/second
    • be backed by 14 global independent laboratories and 7 global patents 
    • Designed in Australia with an Austrlian Patent granted in October 2021
    • provide a solution to treat Australia’s Bore Water 
    • last 7,500 litres – depending on water quality
    • 100% Australian Designed, Owned & Operated

When you use our Bore Water & Sediment Pre-Filter to fill your tanks and then our “5 in 1” to purify your water within the van – you are providing your family with a long lasting scientifically formulated and proven caravan water filter system that is designed to meet Australia’s Bore Water Conditions and purify water to Australian Drinking Water Standards for E.Coli.

How should you use The Complete Caravan Water Filter & Purifier Kit

The Problem: 

Traditionally available, Granular Activated Carbon filters are not the right type of filter to fill your tanks. The first stage of all good water filtration systems is ‘sediment’ removal, not carbon filtration. Additionally, you want to take in the chlorinated water into your tanks. Why? you ask! For two reasons, 1. the chlorine is provided to you free of charge and 2. the chlorine is working hard for  you in your tanks, keeping your tanks and the water in your tanks clean and safe. Additionally if you fill your tanks with a granular carbon filter using bore water, that granular carbon filter will mineralise and clog from the dissolved minerals commonly found in bore water, rendering it useless very quickly.

The Solution: 


Fill your tanks with our 5 -micron Bore Water and Sediment Filter – this will reduce the calcium, magnesium and iron found in Australian bore water as well as reduce sediment, silt and dust which can create a biofilm in your tank. Sediment should always be removed before a carbon filter, as sediment provides an ideal source of nutrient for bacteria to colonise in granular activated carbon filers. This is how our municipal councils treat water – they always start with ‘sediment’ removal and so should you! 

STEP 2. 

Then, “Purify” your water inside your van installing the Thirsty Nomad “5 in 1” Purifier as a dedicated drinking water & cooking water purifier. The Thirsty Nomad “5 in 1” purifier will remove heavy metals, remove chlorine, colour, taste & odour and kill 99.9999% of harmful pathogens.  Install our purifier after your pump, in a dedicated cold water drinking line. The “5 in 1” Permanent option comes with all the fittings you need to simply connect your purifier into your water line with simple push fittings.

NSF/ANSI Standard 61 Heavy Metal Removal media 

Highly effective adsorbant media for the reduction of arsenic III and arsenic V, cardmium, copper, antimony, lead, mercury, uranium, zinc and selenium. Fast kinetic media to work effectively at high flow rates. NSF 61 Certified. 

5 Micron Carbon Fiber Block 

The carbon particles in a block filter are 5 to 20 times smaller than the particles used in Granular (or loose) Activated Carbon (GAC) filters. For too long caravan water filters have been outdated GAC. The technology has moved on from those that were developed over 20 years ago!! Carbon block filters are much more tightly packed than GAC filters which means that the block filters out far more contaminants. Whereas some contaminants may be able to escape the loose carbon found in GAC filters, the compact nature of carbon block filters means that even the smallest particles and contaminants cannot pass through the filter. In addition, the compact nature of carbon block filters means that it takes water much longer to pass through the filter. This lower flowrate further increases the effectiveness of carbon block filters and contributes to much higher purification rates than a GAC filter. What we really love about the carbon block is it’s ability to remove high chlorine levels over the life of the filter – you can see these results published in our Laboratory Results secion. 

0.1 Micron Ultrafiltration – membrane filter 

Ultrafiltration has a micron rating of 0.1 micron – that’s 10 times finer than any other inline caravan water filter available in Australia today. The Ultrafiltraiton membrane will remove viruses (in addition to bacteria, parasites, microplastics, silt, sand, and cloudiness). Ultrafilters are capable of removing 99.999% (log 5) of viruses, 99.999999% (log 8) of bacteria (including E. coli), 99.999% (log 5) of parasites (Giardia, Cryptosporidium, etc.), and 99.999% (log 5) of microplastics.

Quantum DisinfectionTM media. Meets NSF/ANSI Standard 61 and NSF/ANSI Standard 42 and importantly NSF/ANSI Protocol 231.

Invented by Dr Cristian Chis, PhD in Water Chemistry and exclusive to the Thirsty Nomad, Quantum Disinfection media, destroys 99.9999% of harmful bacteria and viruses at the molecular level in 0.01/second. Performs the same disinfection function as Ultraviolet, but with no chemicals and no power and mets the strict Protocols of NSF Protocol231 for water disinfection.

UV treated high strength, clear polycarbonate compact  filter housing 

Can withstand water pressure up to 150psi. We have nothing to hide and want you to see your caravan water filter components at work. Polycarbonate has very high heat resistance and high UV resistance. Polycarbonate provides longevity and strength while being lightweight. Polycarbonate plastics are an engineering plastic – in that they are typically used for more capable, robust materials such as in impact resistant “glass-like” surfaces. Polycarbonate is also recyclable. 

Standard 1/4″ to 1/2″ BSP male, LEAD FREE brass hose connectors that will fit many standard connectors, including braided water hose with two female ends

The brass connections are lead free –  the issue lies with cheaper fittings that are NOT guaranteed to be lead free. Our fittings are guarnteed lead free. Lead can slowly leach trace amounts of lead into drinking water.  Lead exposure can permanently damage the brain and impair intellectual development and is particularly detrimental to young children.

Standard lead free brass fitting that have a 1/2″ BSP thread male fitting end. 

The 1/2″ BSP thread male fititng is a common size and common thread connection that fits many readily availalbe pipe adaptor fittings.


Caravanning is great fun! It is even better when you don’t have to buy bottled water all the time! I have installed a Thirsty Nomad 5 in 1 Drinking Filter under the sink in my caravan. It has made such a difference when we travel knowing we are using quality water for both hygiene and drinking.

My 5 in 1 filter arived recently, thank you.
For a little while I thought I had the best filter for my caravan.
But the taste of chlorine or fluride made me search for something better. I found it! As soon as I fited your 5 in 1 filter & the onboard water was exhausted, the taste of beautiful fresh water (Sydney tap)
really proved my purchase. Well done. Sold me!
Chris Smart, Kingswood, NSW


I have bought 2 Thirsty Nomad 5 in 1 water filter/purifiers. I have one under the sink in my caravan and the other is part of a kit to pump water from a creek to a bladder in my car and then to the caravan. Full marks to this company for their product and exemplary service. They are passionate about their product and Robert is a technical expert whom you can rely on for advice.
