Whether you're in the desert, travelling in Madagascar, trekking in Nepal or on an expedition in Pakistan, the SteriPen Ultra water purifier is an absolute must. In fact, you'll need it as soon as you get up in the morning and need to brush your teeth. Plus, the water purifier only weighs 140 grams and fits nicely in a wash bag or the lid pocket of a backpack. What's astonishing about this little bacteria killer is how efficient it is. When fully charged, this thing can treat 50 litres of water.
To do this, the water purifier doesn't rely on chemicals like potassium permanganate, which had previously been used on expeditions but turned everything from water to noodles to tea pink. The later water purifiers pale in comparison to the SteriPen Ultra Water Purifier. The UV lamp treatment is completely tasteless and odourless. The water purifier doesn't even need a replacement filter. The lamp treats up to 8,000 litres of water and treats one litre within 90 seconds. The way the Steripen Ultra UV Water Purifier works is basically self-explanatory. Plus, it has an easy-to-read display, which clearly indicates when the treatment is completed. And: And, it has a rechargeable lithium-ion battery. This model holds one litre of water.
