How It Works
Your water goes through a multi-stage process to ensure every drop is clean and safe.
Pre-Filtration
Water passes through sediment and carbon pre-filters to remove large particles and chlorine.
Reverse Osmosis
The reverse osmosis membrane removes up to 99% of dissolved contaminants including lead, fluoride, arsenic, and heavy metals.
Remineralization
The alkaline remineralization filter adds back healthy minerals (calcium, magnesium) and raises pH for great-tasting water.
