Convertube with Sawyer Filter

    Our Convertube turns (almost) any bottle into a SOURCE Hydration System. In this new kit we're adding a fitted in-line filter: you are free to fill and re-fill your source of hydration from any creek, stream, river, lake or pond! 

      Convertube™ + Sawyer Filtering Kit

      Drink from (almost) any source

      The Convertube turns almost any bottle into a hydration system, giving you the ability to drink on the move without taking the bottle out of the pack. With the added inline Sawyer filter, you can refill your drinking supplies from (almost) any source and be sure to drink clean, healthy water.

      Enjoy pure water anywhere you go, without depending on tap or bottled water to refill your hydration system. The Sawyer Mini Filter eliminates 99,99999% of bacteria and protozoa, surpassing EPA recommendations. No chemicals needed - simply backwash the filter in intervals to ensure maximum water flow.

      The Convertube is also a great fit to our Liquitainer Flexible Bottles.

      How it works

      As you drink, the water passes through the side walls of the filter's micro-fibrous tubes, harmful bacteria and protozoa are trapped in the outer walls so you can be confident your water is safe to drink.

      Long lasting

      Filter up to 100,000 gallons from freshwater lakes, rivers or streams. Sawyer filters are so robust, they can be backwashed and reused over and over. No replacement cartridges needed.

      Highest Efficacy

      Removes 99,99999% of bacteria (Salmonella, cholera and E.coli) and 99,9999% of protozoa (cryptosporidium and giardia), exceeding EPA recommendations for removal rates. No chemicals or batteries required.

      Mostly work
      We bought two Convertubes with Sawyer filter to go with our 1L Nalgene water bottles. We used them in our recent trekking trip to Nepal. The convertubes worked fine in most days. However, in the last few days, we had difficulties in getting the water through with one of convertubes. We were not sure what the reasons were. We thought about the possibility of the filter got clogged by dirt in the water. But if that were the case, then both convertubes should have the same problems but that was not the case. Also, the water to be filtered was from the Himalaya mountains and was quite clear from the look of it. But overall we were reasonably happy with it.

      Sounds amazing - trekking in Nepal! Happy to read your feedback. Did you use the plunger every now and then to backwash the filter? That should be done no matter how clear the water looks by eye - and it should resolve any problems with the flow. If backwashing doesn't help, please get in touch with our Customer Service and we'll look into the matter. Enjoy the outdoors with SOURCE!

      " More to love: The top opens wide like a paper bag for rapid filling. "
