The Thirsty Nomad

Caravan Purifying Filter
Bacterial Elimination - that actually works. Scientifically Proven.

100% Australian Designed, Owned & Operated, the Thirsty Nomad has been engineered by dedicated water scientists – because for too long caravanners have been let down by outdated, overpriced, gimmicky trademarked, hollow marketed filters!

 The Thirsty Nomad caravan & camper trailer water filter is all of these.

You trust us with your safe water needs in remote locations – that’s a big deal! And it’s not something we take lightly – we were so tired of the high priced, faux -science and quite frankly bullshit, that has been fed to the caravan market for the past 20 years. No advancement in 20 years!! C’mon! 


We are not interested in FALSE claims  like “the only filter with silvermagicgems™ or “silverthisandthat” of with are just gimmicky Trademarks. And, even worse, silver has been unequivocally dimissed by the W.H.O for point of use drinking water disinfection. 

We are not interested in the hollow marketing of these gimmicky trademarks, and nor should you!  Certainly not when it comes to your safe water needs.  (Trademarks which, by the way, can be registered by anyone with $500 and 10 minutes). We are not about providing dangerous  misinformation regarding bacterial elimination capabilities. We respect our customers intelligence.  

We are not interested in giving caravanners an over priced filter that is just the same old, tired granular activated carbon technology that has not advanced in over 20 years. 

Imagine if the airline industry or the medical industry did not adopt the latest in tested and proven technologies. Nor are we interested in producing cheap copies of this tired old technology being used in the wrong application.  


We are water scientists, we focus on thoughtfully, obsessively created, stringently formulated and scientifically proven water purifyers that are proven to work. Now, and in 40 years time. We are transparent, we publish our laboratory results for you to make up your own mind.  One of the keystones of The Thirsty Nomad is transparency. We are an open book so that you can easily assess for yourself if our products will be useful for you. We tell you exactly what is in our purifier and what is not in our purifier. 

There is no “silver bullet” when it comes to water purification and above all we will be “honest” with you about what our water purifiers can do and importantly what they cannot do

The Thirsty Nomad “5 in 1” caravan water filter is a multi-stage purifying water filter unit contained within one light compact unit which can be used to fill your tanks or installed with simple quick connect fittings in your van. Filter unit comes complete, ready to go, with fittings.

Stage 1. NSF certified heavy metal removal media – including Fluoride removal. 

Stage 2.  NSF certified carbon fiber block provides up to 20 times higher contaminant removal than granular activated carbon

Stage 3. SGS Laboratory Tested, Medical grade nano fabric to protect carbon block from 99.9% of bacterial colonisation

Stage 4. NSF certified 0.01 micron ultrafiltration removes 99.999% of viruses, 99.9999% of bacteria (including E. coli), 99.999% of parasites (Giardia, Cryptosporidium, etc.), and 99.999% of microplastics.

Stage 5. Quantum Disinfection media, certified against NSF Protocol 231 meaning it is a certified ‘disinfectant media’. The Thirsty Nomad’s proprietary Quantum DisinfectionTM kills 99.9999% of bacteria and viruses in 0.01/second – tested to NSF Protocols.

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.

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 0.01 micron – that’s 100 times finer than any other inline water purifier 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. 

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 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.

What do our customers say....

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 3 in 1 Inline Filter to my water tanks and a 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” 

– Eric and Sue Kozij | Crusader Caravan Owners Club

“We tried other filters and found that, after a short time, they did not remove chlorine. So, we installed a Thirsty Nomad and are really pleased with the result,  the taste is fresh and pure. My husband and I are  pleased that the Thirsty Nomad provides us with the latest in water purificaiton technologies, based on scientific evidence and facts”
