Concerned about where your family will find safe drinking water if there’s a disaster or boil water advisory?

  1. Press button to activate
  2. Place lamp in water

It’s that easy! When the treatment is complete, the lamp turns off and an LED indicator lights up so you know you can hydrate safely.
