Inside is a powerful activated carbon filter that can remove up to 99.99% of viruses, as well as protozoa, bacteria, particulates, chemicals, pesticides, herbicides and heavy metals. The filter also lasts up to 3 years, or good for cleaning around 40 gallons of water.
A flow rate of 3 liters per minute means the entire 16.9 ounce drinking bottle can be filled with fresh, purified water in just 10 seconds.
Made of tough, but lightweight CP4 Grade 1 titanium, the bottle is rugged enough to withstand battering on any adventure. For convenience, an integrated cup can be used for drinking or boiling water over an open fire or camp stove.
Grayl has somehow made this versatile bottle fit any cupholder or backpack pocket. It is an essential for any outdoorsman, and you can grab one here.
