How does UV water purification work

UV water purification method uses Special lamps which emit UV light waves/ rays which are also called frequency. The unique lamp is surrounded by clear Quartz sleeve which prevents direct contact with water and prevents short circuits.

Water passes through the special lamps that emit UV light frequency. This UV light frequency penetrates through micro- organism DNA code, attacks, disrupts and rearranges microorganism DNA code causing them to become inactive and stop reproducing further.

The best frequency used to kill germs is 254nanometer (nm).

Most of the people fear this method because of exposure to ultraviolet rays which they believe cause cancer. The method is approved to be safe for human consumption because the process of exposing water to ultraviolet rays is done in an enclosed container causing no risk to the human being.

Also, it is safe since you don’t add chemicals to clean water.

Common components that are used in the ultraviolet method include:

  • Sediment pre-filter
  • UV lamp
  • UV quartz sleeve
