Coffee Filteres - A Quick Filter In An Emergency. Tips: Strain water through a bandana, shirt, or coffee filters to remove visible debris. Let the water sit for at least a few minutes, so the remaining particles settle on the bottom, then pour into another container. If at all possible, boil this water to kill pathogens before drinking.

Making A “Filter Bed” Tips: Cut the bottom off a large plastic bottle. Turn the bottle upside down and place a layer of compacted sand, then a layer of gravel and then a layer of pebbles into the bottle. Place the upturned bottle over another a cup or other container. Pour muddy water into the top of the upturned bottle.
