Pack it light and be ready ready for any water emergency. The WaterBasics Emergency Filter Straw is ready to protect you from cysts and chemicals when survival is on the line. The WaterBasics Filter Straw is certified to EPA and NSF/ANSI standards so you can trust the filter to perform as claimed.
Weighing in at a single ounce, each filter takes up less space than a roll of pennies and does'nt cost much more either. A pack of two filters fits perfectly into pockets, packs and very tight spaces. In a pinch, just scoop up some water and drink directly from the package with the straw to keep you safely hydrated when you need it most.
