When it's essential to have a very light luggage, the LifeStraw Personal Water Filter is the ideal solution. The smart water filter weighs only 57 grams and you can put into into water like a normal straw. It's only 22,5 cm long and has a diameter of 2,5 cm, so it fits perfectly in any small backpack.
Without chemicals, batteries, electricity or other spare parts necessary, it can clean up to 1,000 liters, filtering almost all bacteria (99.9999 percent) and protozoan cysts (99.9 percent). The LifeStraw Personal also removes turbidity from water.
There is no bitter aftertaste in the water since there is iodine in this filter. The handy water filter has been tested and certified to meet EU regulations 10/2011 and 1935/2004 for food safety.
