The WaterBasics™ Bag-To-Bag Water Filtration Kit allows you to produce clean, safe drinking water wherever you are using the power of gravity - no pumps required. The kit includes two Water Basics Collapsible Bags, one for collecting “unfiltered” water and the other for receiving and storing “filtered” water. WaterBasics GRN Line Protection and Series II connectivity, assures that the system is safe and easy to setup and use while providing GRN LINE Protection from chemicals, bacteria and protozoan cysts.

The 1 gal. WaterBasics Collapsible Bags are BPA free, made of FDA approved plastics, and are easily filled. They store upright or on their sides, are easy to pour from, and strong enough to safely keep your water. When not in use, the bags can be easily cleaned, dried, rolled up, and stored with the other components in the handy storage bag - ready for future use. The entire kit placed in the storage bag takes up less space than a 1/2 gallon container, making it easy to carry in a car, RV or backpack.

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 water bottle, pump and gravity flow applications. WaterBasics GRN Line filters have been thoroughly tested by independent laboratories, and 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 GRN Line Emergency Filters provide superior biological protection, high flows and long service life in a compact, lightweight, and easy to use system.

Gravity powers the WaterBasics Bag-to-Bag System producing safe, clean drinking water for you and your family. 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 “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.
