Choose From Our Range Of Compatible Filters Available:

Standard Filters | GT2-0K + GT4-6CTO

These are the most commonly used filters in both caravan filtration and also in home undersink filtration.

They are affordable and affective.

Silver Impregnated Carbon GT2-0K + GT4-58BCCP5

Whilst carbon effectively removes odors and taste issues from water, it will leave behind microscopic metal compounds in the form of minute ash/dust particles, which in turn prove to be a source of nourishment for bacteria. This bacteria feeds off the nutrients in the insoluble ash and can then be flushed into the drinking water supply. 

Silver Impregnated Carbon is proven to stop the growth of ash/dust fed bacteria
Filtration Process: When a cell of bacteria is absorbed into the carbon's structure, it comes into contact with silver ions. 

The sulphurhydryl group already within the bacterial cell reacts with the silver, producing a silver sulphur complex. 

The complex immobilizes the respiratory activity of the bacterial cell by preventing the transfer of hydrogen and an oxidative reaction.

The cell cannot reproduce and dies, reducing the risk of gastro illness by ingesting bacteria.

Water Sanitation While Travelling

From time to tome you may find yourself at a site or off the beaten track where only "non potable" water is available. To avoid having to boil your water, HydraSil can be used in its place. It is an odourless, tasteless and colourless sanitiser made up of Silver Stabilised Hydrogen Peroxide (7.5%) and is entirely food grade. It is commonly used to sanitise tank water to kill the bacteria and viruses for drinking water. 

In a travelling application using a 20L Water Storage Container, after filling through the 0.5 Micron Caravan filter, the water will be free from parasites and cysts, however Bacteria and Viruses will still remain. Simply add 4mL of HydraSil into the water and allow to sit for about an hour while it works its magic on the water.

HydraSil is a hydrogen peroxide, based with a silver activated sanitiser, which acts to oxidise bacteria, without leaving any dangerous residues behind. 
HydraSil sanitises and protects your tanks and water storage devices, making the water safe and suitable for human consumption. 
HydraSil is not a chlorine based chemical like most sterilizers on the market today. It is non toxic, and safe to use around your home and family.
