Due to popular demand and ongoing feedback from Caravaners, Nomads and Travellers all across Australia We have decided to release the Triple Caravan Water Filter System.

Some cheaper versions of this original system are not supplied fitted with a suitable, sturdy mounting bracket. The result of this is a huge stress on the centre joiner, which in turn can cause leakage and even complete failure of the joiner nipple. Can be externally mounted or plumbed in. Whilst it can be plumbed in, this is only recommended for internal installation. If used externally, detach the system when in motion to avoid damage. 

The port sizes are 3/4" for high flow to 45 LPM, however, to maximise the efficiency of the carbon cartridges for drinking water purposes, you should not exceed 15 LPM.

Please note: under no circumstances should a thread sealant be used on water filtration housings – thread
tape ONLY is permitted. If thread sealants are used, all warranty is void.

Filter Selection

About Pleated/Washable Sediment Filters

Whilst other filter systems tend to block very prematurely - our Triple Filter design is up to the task of handling heavy sediment with a Pleated Pre-filter as standard. Pleated filters are washable and reusable, so you can rinse out any coarse debris to prevent clogging, and they also help to protect the filters thereafter from clogging up prematurely. Pleated filters also have 20x the surface area of a standard polyspun filter, giving them more surface area to catch debris and a longer life! You won't find a filter such as this one anywhere on the market that even comes close to its quality.

About Polyspun Sediment Filters

These economical sediment cartridges are constructed from polypropylene which is spun and melted simultaneously. This technique means there is no centre core to restrict filter performance. The sediment filters are compatible with most liquids and are highly effective for sediment, rust, sand, silt, and algae removal. Sediment filters have no chemical residuals. They are extremely high performing, carry a heavy load of sediment before requiring replacement. We choose to use these sediment filters over all other types due to the high performance, high flow rate, high load capacity, and inability to grow bacterial slime. 

About Coconut Carbon Block Filters

The perfect carbon block filter is made from 100% Coconut Shell Carbon, which creates what many believe to be the sweetest-tasting water. The unique pore structure of coconut carbon is well suited for chemical adsorption, including VOCs, while reducing chlorine and chemicals that contribute to taste and odour.

This high quality 100% Coconut Carbon filter is the exact filter we use as our front-line carbon filter. As a rule, it is difficult to find 100% coconut carbon filters. Most lower priced filters on the market are a blend of coconut carbon and coal-based carbon. However, the problem with coal-based carbon is that it has a shorter life and often results in a less palatable flavour. We use this 100% coconut carbon filter in all of our pre-assembled kits.


Filter Combinations

Standard Sediment + Chlorine, Taste + Odour Coconut Carbon (For Mains Water)

Ideal for frequent use on Chlorinated Mains Water.

Fine Sediment + Silver Impregnated Carbon (For Mains or Rain/Potable Bore Water*)

Whilst carbon effectively removes odours and taste issues from water, carbon ash is a source of nourishment for bacteria, and unfortunately, carbon filters can quickly biofuel if left in wet and warm conditions. Silver impregnated (bacteriostatic) carbon, however, prevents biofouling and extends the life of the filters, as it immobilises the respiratory activity of the bacterial cell and prevents bacteria from breeding in the filter. The Silver Carbon filter combo is therefore suited to applications where the system may not be frequently in use for periods of a week or more. Recommended for use with rainwater/caravan use for the convenience of not needing to be prematurely changed due to bacteria growth. 

Sediment + Silver Impregnated Carbon (For Rain/Potable Bore Water*)

These filters are universal in the fact they can perform the job of the standard filters but allow you to use water with higher sediment content. The 20-micron washable pre-filter prevents premature clogging up, followed by a 5 Micron Poly Spun, then a 0.5 Micron Coconut Carbon Block.

Heavy Sediment (Not for Drinking)

These filters are suitable for water that is visibly dirty and there are signs of heavy sediment. The pre-filter is a 100 Micron Mesh Strainer for easy washing/re-use. The secondary filter is a 20 micron washable also which should produce clear water and a final 5-micron polishing filter. These filters are ideal for tank filling or running the toilet. Additional filtration/sanitation is required for drinking.


Filter Replacement Packs & Schedule

Caravan filters are recommended for replacement every 6-12 months, or as required. Please see below for the links to the full replacement packs for this system:



Disclaimer: Do not use or drink microbiologically unsafe water or water of unknown quality without adequate disinfection. 


FSA’s Recommendation for Caravans, Campervans + Travellers on Rain/Tank/Potable Bore Water*

If during your travels you will ever use Rain/Tank Water and Potable Bore Water (*i.e bore water that has been tested to the Australian Drinking Water Guidelines and deemed suitable for drinking purposes per the Guidelines’ aesthetic, health and safety recommendations), please see below our recommended filtration schedule to ensure safe drinking water:

  1. External Sediment + Carbon Pre-Filtration to Prevent Tank Clogging + Improve Initial Taste & Odour
  2. Tank Dose with HydroSil Ultra 7.5% for Protection Against Bacteria & Viruses
  3. Undersink <1 Micron Absolute Filter for Protection against Parasites & (Optional) Coconut Carbon for Improved Final Taste & Odour

Read on for a full explanation of why we recommend this as the minimum standard of filtration for treating Rain/Tank/Potable Bore Water for drinking purposes.


For Protection Against Bacteria/Viruses

Bacteria (such as E.Coli) can colonize in stagnant water and result in harmful illnesses when consumed.
For sanitation against common water-borne bacteria/viruses in rainwater and potable bore water*, we, therefore, recommend dosing your tank with a product such as Hydrosil Ultra 7.5% Water Sanitiser to ensure protection against microbiological contamination/biofouling in your pipework and/or filter system.

HydroSil is a food-grade silver and hydrogen-peroxide based water sanitiser, which acts to oxidise bacteria and viruses without leaving any dangerous residues behind. HydroSil sanitizes and protects your tanks and water storage devices, making rainwater and potable bore water* safe and suitable for human consumption. HydroSil is not a chlorine-based chemical like most sterilisers on the market today. It is non-toxic, and safe to use around your home and family.

Dosage Rate: HydroSil should be dosed at a rate of 200mL per 1000L of water.
To scale down to tank size, you will require 20mL per 100L.

For Protection Against Parasites/Protozoa

Ingesting waterborne parasites (Protozoan Cysts) such as Cryptosporidium and Giardia (which flourish in raw water sources such as rain water tanks and bores), are a common cause of gastroenteritis.

Whilst Chlorine can inactivate Giardia with a moderate dose and contact time, Chlorine has a negligible effect on Cryptosporidium unless dosed in excess of the acceptable Chlorine limit listed in the Australian Drinking Water Guidelines (Version 3.6, pp. 200).

For protection against these common cysts, we, therefore, recommend under sink filtration down to at least 1 Micron (Absolute) or smaller (i.e. with Reverse Osmosis or the Caware 0.1 Micron Absolute 3-in-1 Sediment, Chemical + Bacteria Reduction Filter). Please note: 0.1 Micron Filtration is NOT recommended for use with an External Caravan Filter System.

Such fine filtration, used along with regular sanitation (i.e. with HydroSil Ultra 7.5%) is a cost-effective and safe drinking water solution for rain water and potable bore water*, and is perfect for casual disinfection requirements such as when travelling in a caravan.

Why UV Disinfection is NOT Recommended for Travelling/Casual Use

You may have read that Ultraviolet (UV) Disinfection is one of the safest and most effective methods for treating drinking water, as it has a minimal effect on drinking water’s composition and taste, whilst killing 99.9% of microbiological contaminants. It's true that UV is highly effective at inactivating the DNA cells of water-borne micro-organisms such as bacteria and viruses, and excellent at killing chlorine-resistant parasites such as Giardia and Cryptosporidium.

However, as effective as they are, please note that UV systems are generally NOT recommended for travelling and casual use, for the following reasons:

  • UV Systems require electrical input and typically need to be left on 24/7 to prevent degradation of the UV lamp (not ideal for infrequent use).
  • UV radiation also heats up the UV chamber and, in some cases, requires a constant flow of fresh water and a thermal release valve to release the hot water (which is not ideal on a small water tank).
  • UV Systems also contain fragile glass components (not ideal for travelling).
