Like many of the best ideas, it all started with a simple sketch on a bar napkin. It became an obsession: to make the perfect portable water purifier, a device that could deliver safe, self-reliant and sustainable adventures across the globe. Because as all travellers know, access to clean drinking water is vital to any trip. But relying on single-use plastic bottles for hydration is expensive and wasteful.

GRAYL’s solution was a range of portable, compact and easy to use bottle purifiers. Fill it, press down and drink. The design works on every continent, whether you’re drawing water from murky rivers, sketchy taps or stagnant lakes. It uses your own body weight to push water through a two-stage purifier. That means it’s fast – really fast. But it also provides complete protection against all waterborne pathogens, even viruses, and it makes water taste great too, filtering out chemicals, heavy metals and microplastics. You’ll never need to buy bottled water again. In short, it’s the holy grail of water purification.
