The Platypus QuickDraw Microfilter System is an easy-to-use, fast and ultralight fill-and-squeeze filtration system with the best user experience in its category. The simple and rugged design is a two-part system: the 1L QuickDraw Reservoir and the QuickDraw Microfilter. Made of Platy’s proprietary tri-layer film, the QuickDraw Reservoir is taste-free and durable while featuring a wide mouth and convenient handle for hassle-free filling at any water source. Using hollow fiber technology, the QuickDraw Microfilter is capable of filtering 3L of water per minute, while an ergonomic clean side spout makes it easy to deposit filtered water into any clean reservoir or directly into your mouth. The ConnectCap allows the filter to easily fill nearly any water reservoir by filling them through the drink tube with the bite valve removed, or it can use a Platypus bottle adapter kit to fill wide-mouth Nalgene, HydroFlask, Cnoc, and Yeti Yonder water bottles. Two easy and effective cleaning methods—shake-to-clean and tool-free backflushing—ensure fast flow rates stick around for the duration of a trip. With an attached flip-up clean side cap and a grippy-but-not-sticky filter housing, the QuickDraw eliminates frustrations like leaking water in the pack, lost small parts, and dirt-caked gear. The QuickDraw Microfilter System weighs 3.3 ounces total. The filter cartridge measures 5 x 1.8 inches and the reservoir measures 11.5 x 5.5 inches. Limited lifetime warranty. Made in the USA.
