effectively filters tap-water, rain-water, river-water. This type of filter works best to purify tap water, rain water and river-water. the filter eliminates any bad taste/odor and restores clarity to water. it also removes silt, debris, sediment along with over 200 chemical contaminants (including herbicides/pesticides, pharmaceuticals and on and on). note that if you are filtering lake/pond water (or any other stagnant body of water that may contain pathogens) you should pour water thru filter and into a collection container and boil it before drinking. boiling can be done before or after you pour water thru the filter. note: nothing grows in fast moving river water so that does not need to be boiled.

Step 10: Here's How to Pour Water Thru It...
