GRAYL — Press-To-Purify Water Bottles From Seattle

GRAYL started as a napkin sketch in a Seattle bar — an obsession with making the perfect portable water purifier. The first Kickstarter raised over $250,000, and today GRAYL's GeoPress and UltraPress let you press-purify water from streams, hotel sinks, wells, and lakes in seconds.

Press-purifier mechanics

Pour, press, drink. The integrated filter cartridge handles bacteria, viruses, chemicals, and heavy metals in a single 8-second press — making it usable for international travel, sketchy tap water, and backcountry sources without the wait of chemical treatment. See Water Filtration & Purification for cross-brand comparisons.

Beyond the filter

GRAYL's mission empowers adventure with clean, safe water anywhere. A minimum of 1% of every sale goes to environmental charities. Pair with Water & Hydration, Trail Gear, and Emergency Foods.

If you travel internationally or want one bottle that handles every water source, the GRAYL UltraPress is the gateway — eliminates wait time, fits in any pack, replaces three or four other water-treatment items.
