Explanation:
1. Boiling
The simplest and most common method to purify drinking water is to boil it. Heat the water over a stovetop burner or open flame until it reaches a full, rolling boil, and continue to boil for a minimum of five to ten minutes to be safe (the longer the water is boiled, the purer it will become).
Since boiling contaminated water will remove all oxygen from the liquid, the resulting purified water may end up tasting flat. This is a very minor negative that can easily be fixed by simply shaking the purified water up a bit.
Also, to improve the taste, a pinch of salt may be added to each quart of drinking water.

2. Commercial Filters
There are quite a few ways to filter water for safe drinking. Porous materials such as coffee filters and cotton cloths may be used in the event of an extreme emergency, but, naturally, they are not very efficient in removing all unwanted particles.
Commercial filters, on the other hand, are highly successful in removing almost all tannins and soil from contaminated drinking water.
