  • DIY Gravity Water Filter

    Finally decided to make a DIY Gravity Water Filter System

    Ordered the following from Amazon:

    Hydroblu Water Filter ...about $24 ( I have the Sawyer filters but this one came with the nozzle and clip )

    Ordered this kit as it includes the hose ( can not be seen in the package as it is on the back of the package; the filter, the clp and a nozzle

    Step One....Find the center fold line on the bottom of the bag and fold the bag in half and then fold in half again.

    Cut a very small hole in the bottom center of the dry bag. Remember, you can always make the hole larger....but not smaller

    You can see the hole at the bottom of the bag. I almost cut it too large.

    Take the nozzle apart and remove one of the plastic O rings.

    The part on the left will go in the bag and the you push the end thru the hole in the bottom of the bag.

    Once the nozzle has been pushed thru the bag; place the O ring over the exposed nozzle and screw on the cap until it is finger tight.

    Add the hose and clip and fill the bag with some water and hang up to check for leaks.

    I hung mine from the shower head. After an hour there was no signs of leaking around the nozzle.

    This set up can also be used with a Sawyer water filter.

    You can also sew your own water bag and or find a lighter weight dry sack to use.

    I added the filter and the systems works. I will be taking it on my next backpacking trip.

    Total weight of bag, nozzle hose and clip is 4.4 oz. As it is still damp from the water test I figure that this weight is realistic and most times one will not wait for the bag to dry on the inside before packing it up and continuing with ones hike. I am sure I can cut an oz or two if I decide to make (sew ) my own bag ( I have plenty of scrap silnylon I can use ).

      HydroBlu no longer sells the kit like the one I show above. You can find the same kit under a different name here ... Its also about $5 cheaper.
