The QuickDraw micro-filtration system relies on decades of expertise in filtration and hydration to provide adventurers the best user experience of all water filters to fill and press from the market. This easy-to-use system consists of two parts: the 1 liter QuickDraw tank, durable and tasteless, and the filter cartridge in hollow fiber. Barely 95 g and filtering up to 3 liters per minute, the QuickDraw system guarantees quick and easy access to clean water, regardless of adventure. You can either shake the hollow fiber filter to clean or perform a counter-current rinse without tools to make sure that fast flows will remain in place for the duration of your trips. Thanks to its double internal / outdoor thread (I / O), the QuickDraw filter cartridge fits safely to SmartWater® bottles and other Flatty bottles and tanks, which allows you to develop your ideal system to explore with confidence. Wild nature.
