Cleaning Made Easy

The H2O e3™ eActivator emits low levels of electricity, breaking apart water and salt molecules to form two new powerful oxidants. One is a powerful cleaner that cuts through grease and grime; the other is a powerful deodoriser and cleaner!

  • Simply fill the eActivator with water

    The resusable activator lets you say goodbye to single-use plastic bottles and harmful chemicals.

  • Add a little salt from your kitchen

    Just the essentials and all natural.
    No bleach, hydrogen peroxide, preservatives, surfactants, fragrances, phthalates, alcohol, quats or dyes.

  • Shake and press the button

    Watch the science in action as the eActivator emits low levels of electricity that converts water into an all-natural multi-purpose cleaner and deodorizer that is as effective as the leading brands.
