Quick and easy filtration: an outdoor Holy Grayl?

Fifteen seconds to clean water

Quite simple, really

Designed to address the complexity and glacial throughput of traditional water filtration systems, Grayl’s Water Filtration Cup promises to deliver clean, filtered drinking water in as little as fifteen seconds (a coming tap water filter takes only seven).  Working much like a French press, the Grayl’s filter-bottomed inner cup is pressed into its water-filled outer cup.  This design allows the user to quickly and easily scoop water from a stream or other body of water while keeping the un-purified stuff away from the user’s mouth.

The included Grayl G3+ Filter – recommended for outdoor use – consists of a triple ion charged mesh that is said to capture 99.99% of bacteria (such as E. coli and Salmonella) and 99.94% of protozoan cysts (including Cryptosporidium and Giardia). An ultra-powdered activated carbon (derived from coconut husks) absorbs odours and flavors, industrial and pharmaceutical chemicals, and heavy metals. For those of us who don’t clean our gear as much as we probably should, an antimicrobial agent inhibits the growth of mold, bacteria, fungus and mildew between uses.

For the germ-averse or the global traveler (or germ-averse global traveler), an optional G3+ Purifier is available as an upgrade, doubling the mesh to capture 99.999% of bacteria, protozoan cysts, and viruses (i.e. Hepatitis A, SARS, Rotavirus).

With only a 16oz capacity, it’d take six or so rounds scooping, pushing, and pouring to fill a 3L hydration pack.  Still, by doing away with much of the complexity inherent in mechanical pumps Grayl may be on to something.  The Grayl Water Filtration Cup is available direct from the ‘States or in the UK through Cotswold Outdoor for $70 and £50, respectively.
