LifeStraw Flex

The LifeStraw Flex is our newest addition and a real multi-talent. Ultra-light, versatile and with a long-lasting filter:  The LifeStraw Flex can be used in five different ways and is our most powerful personal water filter.

How the LifeStraw Flex works

The LifeStraw Flex is the next generation of the award-winning LifeStraw personal water filter – with additional versatility and protection while still extremely lightweight and long-lasting. It can be used in many different ways, making it the ultimate accessory for traveling, sports and outdoor expeditions.

It includes a 2-stage filtration technology: The first stage of filtration features a replaceable hollow fiber membrane microbiological filter which filters to 0.2 microns and removes 99.999999 percent of waterborne bacteria, and 99.999 percent of waterborne protozoan parasites. At the second stage, the additional activated carbon filter improves taste while reducing chlorine, and organic chemical matter such as pesticides, herbicides, and VOCs. By using the LifeStraw Flex you enjoy expanded protection against lead and some chemicals. The product is ideal for hiking, camping, and emergency preparedness/survival. It includes a collapsible squeeze bottle.

The LifeStraw Flex filters up to 2,000 liters of contaminated water without using iodine, chlorine, or other chemicals. LifeStraw products do not require batteries, have no moving parts and use no chemicals. This displays a great and more innovative alternative to iodine tablets and bulky purifiers. The LifeStraw® technology has been independently tested and certified to meet EU directive 10/2011 and EU directive 1935/2004 regulatory standards.

Therefore, it is the ideal accessory for your hiking, camping and outdoor adventures, travels and emergency preparedness.
