Fulfilling all your group water needs, including drinking, cooking and washing, the Guardian™ Gravity Purifier’s self-cleaning filter cartridge and robust 10L collection bag save on time, space, and need to carry excess bottled water for your group. The easy-to-fill collection bag and cartridge fit neatly inside a handy storage bag, leaving you space in your pack or car for other equipment must-haves. Meeting the NSF P248 military testing standard, the Guardian™ Gravity uses two-stage filtration; hollow fibre to remove bacteria and water-borne viruses, and activated carbon to reduce chemicals and tastes.
