Platypus Quickdraw 3L Gravity Filter System

A versatile, fast-flowing gravity filter system built for groups and extended backcountry trips where water management needs to be efficient and reliable. The QuickDraw 3L converts between gravity and squeeze setups, connects to almost any bottle or reservoir you already own, and filters fast enough that waiting for clean water is never the bottleneck at camp.

Highlights

• 1.75 liters per minute gravity flow, 3 liters per minute with squeeze — Fast enough for groups and high-demand camp situations without standing around waiting. One of the fastest flow rates in the gravity filter category.
• Individually tested hollow fiber filter — Each filter is tested to meet EPA and NSF guidelines for removing 99.9999% of bacteria and 99.9% of protozoa including Giardia, Cryptosporidium, E. coli, Salmonella, and V. cholerae. Tested individually, not just batch certified.
• I/O threads with ConnectCap and Bottle Adapter — Connects to smartwater bottles, Nalgene, Hydro Flask, Yeti, Platy bottles, and quick disconnect hydration reservoirs. A genuinely universal connection system that works with gear you already own without adapters or workarounds.
• 3L tri-layer dirty reservoir — Durable, packable, and taste-free with a wide-mouth opening for easy filling and a detachable hydrophobic hang handle. Detach the handle for squeeze use and reattach for gravity hang setup in seconds.
• Converts between gravity and squeeze — Use it as a hang-and-wait gravity system at camp or squeeze filter on the move when you need water fast. Two filter methods in one system.
• Shake-to-clean and backflush maintenance — Two field cleaning methods that restore flow rate throughout a long trip without carrying extra tools. Simple enough to do at the water source before moving on.
• Integrity test capability — Unlike many squeeze filters, you can verify the filter hasn't been compromised by a fall or freezing with a simple field test. A safety check that matters on extended trips far from help.
• 8.2 ounce total system weight — Light enough to justify for solo use and capable enough to support a group. A strong weight-to-capability ratio for a complete filter system.

Best for

Backpacking groups, thru-hikers, and backcountry travelers who want a fast, versatile water filter system that integrates with their existing bottles and reservoirs. A strong all-in-one solution for anyone who wants both gravity and squeeze capability without carrying two separate filter systems.
