LifeStraw Portable Water Filter
That's where LifeStraw comes in. This highly portable device magically removes a minimum 99.90% of waterborne bacteria, filters up to 1000L of contaminated water, removes a minimum 99.9% of waterborne protozoan parasites & reduces water turbidity by filtering particles of approximately 0.2 microns. Basically, it makes water super safe to drink - and clean-tasting. How refreshing.
