Simple Survival Water Filter Using A 2 Liter Bottle


A Using a 2 liter bottle it is easiest to make this version of simple water filtration. – I’ve seen a larger scale design using silk fabric for the final stage (silk being a finer weave than cheesecloth or bandana).

**Water filtered like this should still need to be sterilized/purified for human consumption – either by a rolling boil for at least a minute or use water purification tablets. But in a worst case scenario, it is better than drinking it straight from the source.
