Grayl Geopress Purifier

A convenient water filter for on the go: the Geopress Purifier from Grayl.

Here’s how it works: First, fill dirty water into the ‘outer’ bottle. Then, take the ‘inner’ bottle, which features a purifier cartridge at the bottom and enter it into the ‘outer’ bottle. Lastly, push down the ‘inner’ bottle through the dirty water. And voilà, chemicals and pathogens remain inside the filter and the ‘inner’ bottle is now filled with clean water. Even the drinking cap protects against cross-contamination and dirt.

So, if you love travelling or simply going on adventures, then you’ve got to get the Geopress Purifier to get some clean water from sketchy water sources.
