How can you purify a water using only materials at home? How will you know if it is purified or not?
Well first it depend where you got it from. From ocean water its best to just boil it for about 6-8 hours. If it's lake water you need a need a filter. This gets the particles, 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 100% .
You can also use a filter for ocean water and proceed to than boil my friend.
