The Thirsty Nomad

Complete Caravan Water Filter System
Bore water filtration & water purification - in 2 easy steps.
Bacterial Elimination - Proven to AU/NZS Standards.
And a solution to treat Bore water.

100% Australian Designed, Owned & Operated, the Thirsty Nomad has been engineered by dedicated water scientists. When travelling Australia, you may encounter highly mineralised Bore Water. Bore Water will quickly clog a standard granular activated carbon filter which cannot kill bacteria. 

Our caravan water filter system is offering you a means to treat the highly mineralised bore water and then purify your water (eliminate 99.9999% of harmful pathogens) in two steps.  

 Your caravan water filter system should be…

    • a purifier as well as a filter
    • designed to reduce the highly mineralised Australian bore water that you will encounter on your travels
    • designed by water scientists
    • provide scientific proof of performance claims
    • kill 99.9999% of harmful bacteria and viruses in 0.1/second
    • designed especially for caravan and camper trailer use
    • filter down to 0.01 micron – 100 times finer than 1 micron
    • be certified to NSF/ANSI Standard 61 and NSF/ANSI Standard 42
    • be proven and tested for microbiological elimination to AS/NZS Standard 4276.7 Water Microbiology
    • meet NSF Protocol 231  – confirming bacteria and virus elimination perfomance of 99.9999% in 0.1/second
    • be backed by 14 global independent laboratories and 7 global patents including an Australian Innovation Patent granted in October 2021
    • provide a solution to treat Australia’s Bore Water 
    • last 7,500 litres – depending on water quality
    • $219.95 including all Fittings & FREE SHIPPING
    • 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 filter water to Australian Drinking Water Standards for E.Coli

Thirsty Nomad "5 in 1" Purifier - Innovation Patent Number 2021106161 Granted 13 October 2021 for a term of 8 years.


The Problem: 

Granular Activated Carbon filters are not the right style of filter to fill your tanks and should not be used as a first stage filter, especially when you encounter Australia’s highly mineralised bore water – which you will. 

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 provide nutrient for bacteria to colonise in granular activated carbon filers. 

STEP 2. 

“Purify” your water inside your van installing the Thirsty Nomad “5 in 1” Purifier – proven, tested & certified to eliminate 99.9999% of harmful pathogens. Install our purifier either after your pump or under your sink. 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. 


The IDEAL water system is to firstly fill your tanks with our 5 Micron Bore Water & Sediment Filter - our filter will not clog like those granular activated carbon filters - our bore water filter will reduce the minerals found in bore water
The Thirsty Nomad Caravan Filter
Caravan Water Filter - certified & tested to Australian Drinking Water Standards for E.Coli. Tested for "0" E.Coli under AS/NZS Standard 4276.7 Water Microbiology
Use the Thirsty Nomad to fill your tanks like this but in all honesty we highly recommend our Thirsty Nomad Bore Water & Sediment Filter be used to fill your van to treat the highly mineralised Bore Water that you'll encounter in your travels, then "purify" your water in your van.
Purification is most effective at the point of use - install the Thirsty Nomad filter permanently in your van - after your pump or under your tap. Purifier can be mounted horizontally or vertically

And then PURIFY your water IN YOUR VAN with our "5 in 1" Purifier



Tested and Proven for microbiological elimination at leading Australian Laboratory Symbio Laboratories to Australian Standard AS/NZS Standard 4276.7 Water Microbiology. 

Designed in Australia for Australian conditions, bringing you the latest in water purification technologies –  tested to Australian Standard AS/NZS Standard 4276.7 Water Microbiology. Meets Australian Drinking Water Standards for E.Coli.

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 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. 

0.01 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″ LEAD FREE brass hose connectors that will fit a standard hose connection. 

The hose connections are lead free brass –  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″ NPS thread male fitting end. 

The 1/2″ NPS 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!

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.
