The Platypus QuickDraw 3L Water Filter System allows you to reduce your reliance on bottled water and simply filter water from almost any natural source – springs, streams, lakes and rivers. The 3-litre gravity version is ideal for small groups spending a night or two out in the wild. The easy-to-use system comes in two parts: the durable and taste-free QuickDraw reservoir and the hollow fibre filter cartridge. Weighing in at 230g and filtering up to 3 litres per minute, the system is lightweight and efficient. It’s also straightforward to clean, even in the field, with no special tools required. The clever inside/outside (I/O) dual-thread design also means that the filter cartridge fits Smartwater and other 28mm thread bottles, and the included bottle adapter will connect to most wide-mouth bottles, ensuring maximum versatility. Platypus QuickDraw 3L Water Filter System Features: Combine & Customise: I/O threads, the ConnectCap™, quick connector-fitted hose, and the Bottle Adapter let you dial in your custom leak-free system using the clean and dirty vessels you prefer, like smartwater bottles, Platy bottles, and quick disconnect-fitted hydration reservoirs. Premium 3L Reservoir: Proprietary tri-layer film dirty reservoir has a detachable hydrophobic hang handle, an easy-fill wide-mouth opening, is super durable and packable—plus it’s guaranteed plastic-taste-free. Ultralight: At just 8.2 oz (233 g), it supports larger groups with clean water without weighing you down. Fast Flowing: Hollow fibers filter 1.75 liters per minute in a gravity setup and 3 liters per minute with squeeze pressure. Easy Cleaning: Easily shake-to-clean the system or backflush it to keep the water flowing fast throughout your trip. Safe & Effective: Each filter is individually tested to ensure it meets all EPA & NSF guidelines for the removal of 99.9999% of bacteria and 99.9% of protozoa.* Integrity Test: Unlike other squeeze filters, easily determine if your filter has been compromised from a fall or freezing by performing a simple integrity test.
