The ultralight QuickDraw 1L filtration system offers fast and easy filtration, allowing users to customize their system with compatibility for multiple vessels to provide adventurers with the best user experience of any squeeze filter available on the market. The 1-liter dirt reservoir is lightweight and compact, capable of withstanding the tough demands of months of trekking. Thanks to the wide opening and fill handle, your hands stay dry while you quickly and easily refill, so you can keep moving. The I/O thread (internal/external thread) on the dirt side of the filter connects to the QuickDraw reservoir as well as to standard narrow-mouth bottles. On the clean side, you can choose between the DrinkCap for drinking and pouring and the ConnectCap, which can be attached to narrow-mouth bottles. The system is designed to be safe, effortless, and durable. Two cleaning methods—Shake-to-Clean and backflushing—ensure that the filter flows quickly throughout your journey, while the Integrity Check process guarantees that the water continues to be safely filtered. With its incredible user-friendliness, packability, and fast flow rate, the QuickDraw 1L filtration system is the best squeeze filter for your backpacking trips.
