How It Works

Three stages

  1. 1

    Pre-filtration

    Water passes through sediment and carbon pre-filters to remove large particles and chlorine.

  2. 2

    Reverse osmosis

    The reverse osmosis membrane removes up to 99% of dissolved contaminants including lead, fluoride, arsenic, and heavy metals.

  3. 3

    Remineralization

    The alkaline remineralization filter adds back healthy minerals (calcium, magnesium) and raises pH for great-tasting water.
