LifeStraw Go is essentially a sports water bottle, but with a crazy-good filter built in. You can use it to scoop up water from just about anywhere in the world and then safely drink it through the mouthpiece.

By the time the water has made it up the straw, the filter has already removed 99.9999% of waterborne bacteria and 99.9% of waterborne protozoan parasites. It can do this for up to 1,000 liters (264 gallons) of water, so you won’t have to replace it for quite a while.

The coolest part is that, for every LifeStraw sold, they ensure that one young student in Africa gets clean water for an entire school year. For only $35, there’s no reason not to support such a great cause.
