GRAYL UltraPress Hiking Bottle Turns Dirty Water Safe to Drink in 10 Seconds


Carrying a bunch of bottled water from home to your hiking adventure wouldn’t be the wisest move to make. You don’t have the space luxury, and the added weight will only make every step bone-crushing. But what if you can process clean water anywhere you go?

GRAYL UltraPress is a bottle featuring a water purifier that kills more than 99.9% of viruses, bacteria, and protozoans. And it does that very quickly.

With the press mechanism, the bottle can quickly filter 500ml of sketchy water safe to drink in just 10 seconds. For context, standard straw-based filters may take a few minutes to achieve the same capacity.
