A highly efficient filtration system that provides drinking water purified of pathogens (viruses, bacteria, protozoa), chemicals, heavy metals and solids in just 8 seconds. Simply fill the bottle with water (from any natural source), squeeze it and in no time you have water ready to drink.
This is taken care of by the replaceable filter cartridge inside the bottle, which uses an ingenious combination of activated carbon and electrostatic adsorption to remove contaminants. You can purify 250 litres of water with a single filter cartridge.
- High efficiency - removes 99.99% of contaminants (viruses, bacteria, protozoa, chemicals, heavy metals and particulates).
- Replaceable filter cartridge (Geopress Replacement Cartridge).

We have spent hundreds of nights in tents in the field and thousands of days in the developing world. We have worked, played and lived in places where access to safe and clean water is a necessity.
Whether we needed to drink from a dirty stream on the trail, refill water in a dodgy hotel sink in Peru or were prepared for an emergency.
GRAYL cares deeply about our planet and we put our money where our mouth is. We donate at least 1% of every sale to environmental charities and non-profit organizations.
