If you select the option of the 5-in-1 purifier with a sediment filter we will assemble this for you and supply the additional fittings required. The sediment filter is similar to the one in the 4th image of this listing and will remove larger bits of sediment, particles, debris and dirt that may otherwise clog your more expensive 5-in-1 purifier faster then it should.
Why filter when you can purify your RV water

 100% Australian Design & Innovation

100% Australian Owned & Operated

POU Purifier
  1. Why just filter water when you can purify your water?
  2. Want to be sure that the water you and your family is drinking is free from microbiologically harmful pathogens and meets Australian Drinking Water Standards?
  3. Want to know that the components in your water purifier are all certified by independent laboratories, to the highest standards? 
  4. Want to know that your purifier is 100% Australian Developed & Owned IP and developed by Water Scientists – two of whom have PhD’s in Water Science?
  5. Tired of paying top dollar for an unknown source of Granular Activated Carbon that only removes chlorine, taste & odour and cannot act as a microbiological purifier? It’s what you can’t see in your water - that matters.


Many water filters provided to RV’s are not designed especially for the conditions in which you are consuming water in your RV. Many filters are designed for household use, not the Thirsty Nomad – whose proprietary water treatment process is a 100% Australian Innovation, 100% owned & operated by two Australian families and designed specifically for the conditions under which caravanners will be collecting, storing and consuming water.  

RV filters commonly contain loose Granular Activated Carbon (GAC), often of unknown origin. 

GAC cannot "disinfect" water so it does not remove, deactivate or kill pathogenic microorganisms such as bacteria and viruses.

GAC may trap micro-organisms, but also provides somewhere for bacteria to colonize.

Let’s take a moment to understand the difference between a bactericidal agent and a bacteriostatic one.

A bactericidal agent is one that is applied to a fluid in order to kill the bacteria contained in it. Examples of bactericidal agents for water treatment are chlorine, iodine, ozone, chlorine dioxide, chloramines and silver ions. The latter are dosed by electrolysis, from a silver anode, in which an electric current causes the oxidation of the metal, which is released into the water in its ionic state (Ag+).

In contrast, a bacteriostatic agent is not dosed into the fluid, but remains fixed in the solid. Therefore, silver-impregnated carbon is bacteriostatic but not bactericidal. In other words, it serves to inhibit bacterial growth on its surface, but does not guarantee the annihilation of microorganisms if they are carried by water in relatively high concentrations.

GAC cannot treat microbiologically unsafe water to Australian Drinking Water Standards, but the Thirsty Nomad can. Below are the results of an Independent Laboratory Test by Symbio Laboratories.

Many filters on the market add silver as an anti-bacterial, however the World Health Organisation (WHO) does not recommend silver as a primary disinfectant in drinking-water supplies, as it has not demonstrated sufficient capability to be considered a candidate for primary 'disinfection'. 

Further, for silver to be effective, it requires long contact times, up to 4 hours, even some products own lab results demonstrate that silver needs 4 hours contact time to be effective. 

This is not practical in a daily use portable filter. 

One crucial factor to consider when buying a water filter is the filtration flow rate. 

This will greatly determine the effectiveness of the filter, and the type of contaminant that is eliminated. 

A slower flow rate is better for greater purification, as compared to a faster flow rate. 

Most RV filters do not control the flow rate or contact time ignoring the science for optimal performance.

The Thirsty Nomad, however, has a flow controller integrated into the outlet fittings, so that you can be sure that the treatment processes of these filters is working to its optimal contact time for optimal performance.

More about Quantum Disinfection TM

No Chemicals | No Power | No Pathogens

What it does?

Quantum Disinfection™ is a new generation of nano-composite materials with activated surfaces that kills harmful pathogens including bacteria (E. coli, Staphylococcus, Legionella, etc.), viruses (MS2) and protozoa (Cryptosporidium) form water, with no power, no chemicals and no maintenance. 

How does it work?

Quantum DisinfectionTM is a revolutionary technology, exclusive to the Thirsty Nomad in Australia. QD has 7 patents worldwide. 

QD uses the quantum mechanic principals of electron movement and doping, in order to create powerful catalysts with highly activated surfaces applied, since 2011, for water and air disinfection. 

A quantum leap away from the classical methods (chlorine, alcohol, bromide, ozone or UV), Quantum DisinfectionTM uses a discharged surface (positive quantum field) that attracts electrons. Water, or air, simply has to pass over the Quantum DisinfectionTM ceramics and the microorganisms (negatively charged) are instantly killed.  

How efficient is it. 

The best results from several institutions and certified laboratories show a 99.9999% elimination for bacteria (E.coli) and >99.99% for viruses (MS2). 

Does it have any certifications?  

Yes. QD media has: 

NSF/ANSI 42 (Certificate #: C0292640-01)

Tested and Certified by NSF International against NSF P231 protocol – which certifies that a drinking water treatment product acts as a microbiological purifier. 

Tested by IAPMO to NSF/ANSI 61 (Certificate #: 23033) 

Certificate Ministry of Health - China (Certificate #: 2015KF2513)

A new phenomenon: attracts electrons from micro organisms (bacteria, viruses) causing
entire structure

kills micro

How QD is applied? 

QD can only be applied in packed bed inside devices, systems, cartridges, units, etc. with an inlet and an outlet that can ensure the contact of the microorganisms with the activated QD ceramics. No by-passes. 

Has QD been tested by 3rd party labs? 

Yes. Quantum DisinfectionTM technology has been rigorously tested and posted excellent results by: - Environmental Protection Agency, USA - Homeland Security (against Anthrax virus), USA - Eurofins,

USA - Pasteur Institute of Lille (now Eurofins), France - NC State University, USA - Proteus, France -

Guangdong Detection Centre of Microbiology, China - Institute of Environmental Health and

Related Product Safety, Chinese Centre of Disease Control and Prevention, China - Avazyme, USA - Ackuritlabs, USA - Microbac, USA - QFT Laboratory, USA - JAMPO (NSF P231 protocol), USA and India All of these reports are available upon request. 

Does QD working in gravity fits? 


Does QD require any pressure? 


Does QD require any electricity? 

No. QD is not an electrical device. 

How long does QD media last? 

QD media is a catalyst that, in theory, do not expire and the positive filed at the ceramic surfaces remains permanently the same. In reality, suspended solids or other particles can get into the vessels and clog the activated surfaces leading to slowly losses of the germicide activity. We noticed that after a certain amount of water or air that passed through, the germicide activity of the QD ceramics can drop, after one year of use, from 99.99% to 99.98% or lower. 


These filters are not approved for permanent connection to mains supply under constant pressure and should only be used as portable filters
