When you find yourself an a survival situation, you do not always have access to chemicals or a filter to purify the water so you can drink it.
You could just boil the water but this would n't get sand and other particles out of the water and the chemicals will also remain in the water after cooking it. Which in turn could affect your health.
So the best way to purify your water is to use a filter.
Often you can build a water filter with the resources you have available, this gets the particules, dirt and some of the chemicals out of the water.
It is wise to boil the water after you filtered it so that all bacteria and viruses are killed.

Signing UpStep 1The Filter
A water filter can be created by removing the bottom of a bottle. Turn the bottle upsidedown (with the cap down down).
and put the following materials in the bottle.
- pebbles
- Sand
- a piece of cloth or bandages
- charcoal
- a piece of cloth or bandages
- Sand
- pebbles
The cloth or bandages are used to ensure that all the different materials do not mix.
The pebbels and sand filter the particules and the dirt out of the water.
The charcoal gets a big portion of the chemicals out of the water, but it won't get it all out. (You can use charcoal from your campfire).
This filter will not remove any viruses and bacteria from the water so you have to boil the water after it is filtered.

Cedar tea will stave off scurvy.
Not a bad article.
A coffee filter can filter out debris nicely.
A good source for activated charcoal is aquarium filters.
How to make Activated Charcoal would be good also.
Take wood, paper, or bone, you can even use nutshells or corn husks.
Seal it in an airtight container.
A glass jar with a tin lid will enable you to watch as the material changes to activated charcoal.
Poke a vent hole in the lid and heat over a fire.
The smoke and hot gasses will escape out the vent hole leaving behind the activated charcoal.
Let cool slowly if you use a glass jar or the glass may shatter.
Activated charcoal used for filters is burned in a container that does not allow air into the container to contaminate the carbon with carbon dioxide or other contaminants. It is pure carbon for a better term.
Activated charcoal used for filters, absorb carbon dioxide and other contaminants, this wont happen if it is already contaminated.
it is true that charcoal and all that would be a lot better if you did not heat the water as it would remove some chemicals whereas the wire mesh would not. But when you boil the water you are removing the chemicals and killing the germs anyway.
