This sophisticated coconut carbon pre-filter minimizes sediment and particles with various micron sizes to prime water for advanced filtration in Stages 2 and 3. The hazards extracted here impact color, odor, and water tastes, so you can see, smell, and experience the difference.
Built to eliminate hidden heavy metals, herbicides, pesticides, and more, this advanced filter removes the covert chemicals and contaminants that most miss including lead, radiation, chromium, and PFAS.
The breakthrough technology inside this filter removes superior levels of fluoride without relying on typical Reverse Osmosis technology that blindly removes beneficial minerals and produces excess wastewater.
