Homemade ultralight gravity water filter

Do it yourself homemade ultralight gravity water filter instructions:

Here is a short video demonstrating how to make a homemade ultralight gravity water filter. Some materials you might already have in your backpack.

The filter cartridge and tubing could be used from your existing filter, they could be restored to the original form if desired since no permanent modifications are made. If using your water filters existing tubing,  be sure not to use the intake (dirty water) hose for the output (clean filtered water) on this project as it could be contaminated from unfiltered water.

Materials Needed:

  • Dry bag or waterproofstuff sack(10 liter is good- but size is flexible)
  • Replacement filter cartridge (or your existing one)
  • Tubing that fits cartridge
  • Wide rubber band
  • Plain dental floss (a few feet)
  • Optional On/Off valve for tubing (ex. Camelback HydroLock)

    Great inspiration. Any tohughts about MEI Voyager? My 2 cents: I ALWAYS TRAVEL with a Thermarest waffle-type sleeping pad. Adds a few ounces AND I stick it under sheets on saggy hostel mattresses-saves my back. Stuck in Venice train station waiting for a 2AM NIGHT train, no problem-unfold pad and crash on the concrete. A couple folds can be cut off to make it even lighter.I carry a silk travel sheet as opposed to bag liner, but I must say I never use it. I also carry a SiL-nylon poncho made custom by Stephenson tents in New England-weighs nothing, doubles as blanket, covers pack-no umbrella, no rain jacket. I m trying to justify carrying a MB AIR or tablet, but Ipod Touch seems to be perfect-takes the edge off the IT blues, Skypes. So I’M thinking of shelling out for a new one-my 2nd generation is OOOOLLLLD>
