To purify water is to make an untrusted source safe to drink. Water from rivers, lakes, rain collection or a questionable tap can carry bacteria, parasites, viruses and chemical contaminants. In an emergency, those are often the only sources at hand. We count this skill near the top of every prepper's priorities, because thirst allows no delay. You can ration food for a while, but you cannot wait out a lack of safe water.
The skill matters to every family. You may shelter at home through an outage, camp off grid, or carry a kit on the road. In each case, light and inexpensive gear plus a little practice turns almost any source into drinking water. Boiling, filtration and chemical treatment are the main methods, and each has its own strengths and gaps.
