How is UV purification superior compared to other methods like boiling, using candle filters etc.?
Conventional methods of water purification commonly used in homes like boiling, filtering or using candle filters have limitations. Boiling for instance, to be effective must be done for at least 20-25 minutes after water reaches boiling point. Further, while the water is being cooled and stored in containers or bottles, there is always the risk of recontamination. This makes this commonly adopted method impractical, time consuming and often not completely safe.
