You have important things to do, and pushing or pulling on a pump is probably not one of them. A few squeezes of the primer bulb starts the process of gravity "pulling" the water through the filter. The weight of the water provides the potential energy to convert contaminated water to GRN Line protected water without breaking a sweat.

With the WaterBasics Gravity Flow Filtration Kit, all you need is two standard water containers to set up a gravity powered filtration system. The Kit includes WaterBasics GRN Line Emergency Filter with the convenience of Series II connectivity to easily connect to most standard water storage containers including jugs and carboys. Simply screw the GRN Line Filter directly into the threaded cap of the clean container , then connect the feed tube to the unfiltered water container. Place the unfiltered container higher than the clean container, give a few squeezes on the primer bulb to start the water flow, and then sit back and let Newton do all the work for you. In about the same time as it takes to make lemonade and kick your feet up, you can have a gallon of filtered water with GRN Line Protection from chemicals, bacteria, and protozoan cysts. You can depend on WaterBasics.

WaterBasics GRN Line Protection is achieved using Electro-Positive Absorption Technology. Charged micro-glass fibers "pull" organisms as small as bacteria, out of the water stream while still maintaining high flow rates and low pressure drops making WaterBasics Series II GRN Line Emergency Filters the perfect choice for gravity flow applications. WaterBasics Series II GRN Line Emergency Filters have been thoroughly tested by independent laboratories and are proven to consistently remove bacteria and protozoan cysts to ANSI/NSF Standard 53 and US EPA standards, without the use of disinfecting chemicals such as chlorine, bromine, or iodine. The addition of sub-micron carbon particles into the filter media increases the absorptive capability required to reduce chlorine and harmful chemicals, bad tastes, and odors. WaterBasics Series II GRN Line Emergency Filters provide superior biological protection, high flows, and long service life in a compact, lightweight, and easy to use cartridge.

Designed with a purpose, the WaterBasics Series II Emergency Filter included in the kit connects easily to any WaterBasics water bottle, to standard water storage containers, and the unique WaterBasics pump. Fewer fittings mean one filter is all you need to protect you and your family without worrying "if it will fit."
