The Sawyer 4L Water Treatment System is easy to set up and requires no pumping or chemicals. Simply let gravity provide you with 4 litres of fresh, clean water in about 3 minutes.

Simply fill the included grey reservoir with unfiltered water, attach the filter and filter hose and let gravity fill the included blue reservoir with clean water.

Use the clean water in your blue reservoir as a campsite water source for dirty dishes and filling water bottles by simply hanging the reservoir from its handle. Or attach the included drink tube and a bite valve (sold separately) and use the reservoir as a convenient pack hydration system.

The filter removes particles, protozoa and bacteria down to 0.10 micron in size, including giardia, salmonella, cryptosporidia, and leptospirosis. The Complete system includes a tap adapter for a thorough backwash when you get back home.

Just in case you never go back home, the included Sawyer filter is fully field maintainable to ensure a fast flow of water. Setup is simple and the system packs easily, with a packable weight at just 12 oz.
