$249.95 (incl. gst)
Sawyer's Two Bag Complete 4l Water Treatment System (model SP184) provides a safe and highly effective way to filter water with the bag to bag gravity flow system -- no pumping, no waiting, no chemicals, and no worries!

The system includes a 0.10 micron Absolute Filter, a 4-litre nylon dirty water dispenser, a 4-litre clean water storage vessel, faucet adapter, drink tube, quick release tube, hanging strap, and cleaning and maintenance instructions. The fast flow hollow fibre membrane uses pore sizes so small that sediment, bacteria, protozoa, cysts and other contaminants are removed to provide you with the highest level of filtration available. The filter removes 7 log (99.99999%) of all bacteria (like salmonella) as well as other harmful bacteria which causes cholera and E. coli and 6 log (99.9999%) of all protozoa such as giardia and cryptosporidium -- exceeding EPA guidelines for removal rates.

Ideal for backpacking, paddling, group camping, and emergency preparedness, the filtration process is practically hands free. Just hang the system from a tree or any source off the ground and watch gravity do all the work. In as little as 1.5 minutes you will have 2 litres of safe drinking water. You can even filter on the go by converting the clean water vessel into a hydration bladder for a pack with the included drinking tube.

This filter does not remove dissolved solids, including chemicals and heavy metals. It's backed by a manufacturer's limited lifetime warranty.


  • Simply fill the included gray 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
  • Filter removes particles, protozoa, and bacteria down to 0.10 micron in size, including giardia, salmonella, cryptosporidia
  • The Complete system includes a faucet adapter for a thorough backwash when you get back home to your faucet.
  • But 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.
