Pre-Mac water purifiers are the most versatile travelling companions I have used. They produce safe, clean water for drinking, first aid, food preparation and personal hygiene. Dont take risks with your health.

The Travel Well Pocket Personal Water Purifier will treat 60 litres (approx 300 cups) of unpurified water. It is able to remove bacteria, viruses and cysts from contaminated water and will provide safe water for drinking, first aid, food preparation and personal hygiene (including the safe cleaning of teeth).
