Drawing on decades of filtration and hydration expertise, the QuickDraw Microfilter System is designed to offer adventurers the ultimate user experience in fill-and-squeeze water filters. This easy-to-use system consists of two components: a taste-free, durable 1L QuickDraw reservoir and a hollow fiber filter cartridge. With a weight of just 3.6 oz (101 g) and a filtration rate of up to 3L per minute, the QuickDraw system ensures speedy access to clean water during any adventure. You can either shake-to-clean the filter or perform a tool-free backflush to maintain the fast flow rates for the duration of your trip. Featuring an inside/outside (I/O) dual-thread design, the QuickDraw filter cartridge can securely adapt to smartwater bottles and other Platy bottles and reservoirs, allowing you to create your ideal system for confidently exploring the wilderness.
