There are multiple methods of purifying water and getting rid of various viruses and harmful chemicals. Here are five natural water purification methods that are cost-effective.

  1. Boiling

    The most effective means of water purification is boiling. Keeping water at a vigorous and rolling boil for 1 to 3 minutes will eliminate all sorts of bacteria within the heat range.

  2. Chlorination

    This is an emergency-based water purification solution which can be done with household bleach. Adding 4 to 5 drops per litre of water will swiftly kill many harmful microbes.

  3. Clay pots and gravity

    Keep activated charcoal at the bottom of the pot. Charcoal will clean and enrich the water at the same time.

  4. The sun

    Store water in glass bottles and leave it in the sun for a minimum of 6 hours. Avoid using PET bottles.

  5. Filtration

    Use a screen of cloth or other material to add a layer of filtration to tap water.
