Like the QuickDraw System but without the reservoir, the easy-to-use QuickDraw Microfilter will revolutionize your adventure filtration system. With its inside/outside (I/O) dual-thread design, the QuickDraw filter cartridge securely adapts to smartwater bottles, most Platy bottles and reservoirs and many common soda/water bottles allowing you to develop your ideal personalized kit. Weighing just 2.2 oz (63 g) and filtering up to 3L per minute, the QuickDraw allows simple fill-and-squeeze water filtration during ultralight missions and any other adventure. You can either shake-to-clean the hollow fiber filter or perform a tool-free backflush to ensure the fast flow rates will stick around for the duration of your trips. Design elements like the attached clean side cap and grippy-but-not-sticky filter housing eliminate frustrations like leaking water in the pack, lost small parts, and dirt-caked gear so you can confidently go out and explore the wilderness.
