GRAYL is on a mission to change the way the world drinks water.
Our goal was to create the most advanced personal water filter on the market- made of stainless steel, with the function of a coffee press and the most advanced filtration technology available. The Water Filtration Cup was born after a dozen engineers said it couldn’t be done. GRAYL lets you take control of your water quality while reducing reliance on plastic water bottles.
GRAYL filters heavy metals, chemicals, flavor/odor, bacteria and protozoan cysts (tap and many outdoor sources). Use the optional Purifier for virus protection (international travel).
