Never buy another charcoal/activated carbon filter for backpacking ever again. Never worry about leaks because this diy job uses no glue. Properties: removes chemical tastes from your water, improves water taste, easily field serviceable, self-cleaning(germs), not likey to freeze, removes foreign chemicals/contaminants, save money and time. With the purchase of bulk materials and the necessary parts you will be able to refill this system for years to come, saving you lots of dough you would have spent buying another filter. This system is meant to be used with chemical treatments like chlorine dioxide tablets or bleach. To prevent freezing, simply blow as much water out of the filter as you can when your done using it. This will also restore filter nearly back to its original weight before being used.

This filter wil also work in an inline cambelbak type system, You can easily suck water through it.

A note about results: Results will be directly dependent on the quality of your activated carbon, density inside the unit and exposure time.

Hey, great post btw. This is such a great idea. I was just googling this and then found it on BPL.

- First of all do you have new Youtube links? The ones posted are already dead.

- How do you actually use your filter, will those tips actually work with Camelbak hose?

- How did you put it together, are those just 2 bottles taped together?

Just be aware that this device has ZERO guarantees! It may well remove large floaties and some taste, but that is all! Bugs are likely to go straight through it.

Roger, I'm no scientist, but this should work like any carbon element for improving the taste of water and possibly removing things like trace metals, chemicals etc.

It is not intended as a filter itself; this is for using WITH a filter, bleach or Aqua Mira. I'm pretty sure Ike's previous thread shows this as an economical part of an over-all system.
