Here is a HydroWell water processing System with Osmotic Filter. This has not been used. New but open packaging. Outside Shipping box has stains but that should be expected. I will try to ship inside another box but I may have to send it in its current boxing. I do not see an expiration  date on syrups but usually syrups last a long long time. You judge for yourself. See pictures and ask questions to decide for yourself. What you see in pictures is what you get. Sold As Is. All sales Final. Below is from online describing it. 

HTITM HydroWell® Hydration System turns virtually ANY water source into clean, drinkable water.

HTITM has worked with the U.S. Military and numerous disaster relief agencies to produce the best, most reliable hydration systems in the world. Their latest effort is the HydroWell®, a water can-style Hydration System that provides 30 liters a day of highly safe, electrolyte-enriched drink from nearly ANY water source. The special filter membrane is built right into the cap to remove viruses, bacteria, heavy metals and cysts with no pumping, no harsh chemicals required.

Simply fill one can with dirty water, apply one of the included syrup pouches to drive the osmosis process, and the HydroWell 2 immediately begins pumping clean, electrolyte-infused drink into the other can. It works at a rate of about 1.2 liters per hour, and you can start drinking it at any time. Each pouch filters about 20 liters... you get 20 pouches total.

It's a terrific system for safe, clean hydration in remote locations, and something no emergency preparedness kit should be without. Check out the details:
  • Filter meets or surpasses reductions for bacteria, viruses and cysts, as specified by the EPA for water filters
  • Filter lasts about 90 days of continuous use, and is easily replaceable
  • Filters about 1.2 liters an hour, or about 30 liters a day
  • Includes 20 syrup pouches to drive the osmosis filtration process. Each single-use pouch helps filter about 20 liters of electrolyte-infused drink
  • Each can has about a 20 liter capacity
  • Non-clogging filter means expanded water source options
  • Reduces water logistics burden by a factor of 35+
