The Grayl Ultrapress is a highly efficient filtration system that can purify drinking water from pathogens (viruses, bacteria, protozoa), chemicals, heavy metals and solids in just 10 seconds .
No matter where you are on any of the 7 continents, all you have to do is fill the bottle from a natural or untrusted water source, squeeze it like a Frenchpress and you're ready to drink in no time.
The replaceable filter cartridge housed inside the bottle uses a sophisticated combination of activated carbon powder to remove contaminants, absorbing both chemical and organic substances, and electrostatic absorption capable of trapping particles as small as viruses.
It filters out all waterborne pathogens, including viruses (99.99% viruses, 99.9999% bacteria, 99.9% protozoan cysts). Ultrafine activated carbon filters solid particles (sediments, microplastics) and absorbs many chemicals, pesticides, herbicides, heavy metals, organics, aromas and odors.

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.
