Overview
Filling the outer cup from a river or faucet, pressing the inner cup down on the ground and drinking is the whole process with this GRAYL purifier. A titanium body stands up to rough trips.
Removing viruses as well as bacteria makes it suited to international travel where tap water is suspect. Each press makes a single bottle, so a group needs several rounds.
Who it's for
International travelers, hikers and hunters who want one bottle that handles viruses get a quick, simple tool. Base camps treating gallons for several people should look at gravity systems.
Pros and cons

Performance notes
Pressing forces water through a cartridge that uses electroadsorption and activated carbon to catch pathogens and adsorb chemicals. A single press treats one full bottle.
