No other portable purifier rivals the speed, simplicity and effectiveness of Grayl purifiers. The design uses Grayl’s proven filtration & purification technology in a coffee-press-inspired format; simply fill the main cylinder with untreated water, insert the filtration sleeve, push down, and in roughly 10 seconds the water within meets the EPA’s strict standards for purification.

Effective on all seven continents, you can tap into the world’s polluted water sources and safely drink from sketchy hotel sinks, murky rivers, wells or lakes. Grayl removes global waterborne pathogens such as viruses, bacteria, and protozoan cysts while filtering pesticides, chemicals, heavy metals, and even microplastics from your water.
