Pocket Travel Well is designed to meet specific requirement for treatment of water in emergency or survival conditions. Using the proven filtration and sterilisation system of Pre-Mac's highly successful PWP, Pocket Travel Well will provide safe drinking from contaminated sources. Size and weight have been kept to a minimum for inclusion in emergency ration packs.

In operation the source water is initially filtered, cleaning the water as well as chemical contamination. This is followed by disinfection using an iodine-resin complex which acts as a contact microbiocide but also releases a low level of iodine into the water for secondary disinfection. Secondary disinfection occurs during the recommended holding period.

Pocket Travel Well is convenient to use and will not block due to its high filtration capability and in-built pump. The rated capacity of Pocket Travel Well is 50 litres, at which point it should be discarded.

The effectiveness of Pocket Travel Well has been proven in tests carried out by the London School of Hygiene and Tropical Medicine. In these tests total elimination of the bacteria Escherichia coli at 10^8.4 per litre was recorded whilst reductions of Poliovirus in excess of 99.9%, with a holding time of 2 minutes, were recorded. This effectiveness is maintained throughout the stated treatment capacity of 50 litres.
