Platypus QuickDraw 3L Gravity Filter System

Jump to: Our Verdict / Features / Specifications

The Platypus QuickDraw 3L Gravity Filter is a high-performance water filter that removes 99.9999% of bacteria and 99.9% of protozoa. It can be used as a traditional gravity filter or converted to a squeeze filter.

Platypus says: 

The multi-compatible QuickDraw 3L Gravity Filter System is the most versatile ultralight gravity filter on the market. Able to convert from a gravity system to a squeeze setup when you want it, it can do it all with your preferred bottles and reservoirs. At the core of the system is the iconic fast-flowing 0.2-micron hollow fiber QuickDraw Filter. The 3L dirty reservoir’s hang handle makes for quick-and-easy hang-ups and is sized for comfortable carrying when it’s full. The handle easily detaches to make compressing and rolling the reservoir down hassle-free when you opt for squeeze filtering. The QuickDraw filter can attach to many different bottles and reservoirs with its I/O (inner/outer) threads on the dirty side and the ConnectCap™ on the clean side. For added versatility, the system’s hose is fitted with a quick connector that attaches to any hydration reservoir with a quick disconnect, as well as clicking into the QuickDraw’s Bottle Adapter. The Bottle Adapter is multi-compatible and vented, meaning common hard-sided wide-mouth bottles and narrow-mouth bottles are all game to hold your freshly filtered water. The system is built to be safe, effortless, and long-lasting. Two cleaning methods—shake-to-clean and backflushing—keep the filter flowing fast throughout your trip, while the Integrity Check process allows you to ensure it’s still safely filtering water. If there ever was one, the QuickDraw 3L Gravity Filter System is the one backcountry water filter that does it all.

Our Verdict

The QuickDraw 3L Gravity Filter from Platypus is an incredibly versatile, high-performance water filter. At its core, the Platypus QuickDraw is a 0.2-micron hollow fibre filter that removes 99.9999% of bacteria and 99.9% of protozoa from untreated water sources.

It can be used as a traditional gravity filter by hanging the 3L dirty reservoir and letting water flow into your clean container. Or you can convert it to a squeeze filter by detaching the reservoir’s handle and squeezing.

Thanks to the included ConnectCap, Bottle Adapter, and quick-disconnect hose fittings, the filter connects to a wide range of bottles and hydration reservoirs, so you won’t spill a drop of water. 

With a fast 1.75 L/min gravity flow rate and up to 3 L/min squeeze rate, the QuickDraw can supply clean water rapidly for groups. Cleaning is easy; simply backflush (with clean water) to dislodge captured particles.

An integrity check procedure lets you verify if the filter has been compromised from impacts or freezing. 

While this may be overkill for a single hiker, if two or three of you are hiking together, it could be an efficient weight-saver.
