Filters

Multiple filters with multiple stages allow for more efficient filtration.

Trial Period*

Enagic® only allows 3 days with a full refund, up to 30 days with an $800 restocking fee. Most others are 60 days with a 15% restocking and processing fee.

Hard Water Adjustment

Hard water can affect the quality of the water an ionizer produces. Adjustment allows you to get the best performance possible.

ORP Levels

ORP (Oxidation Reduction Potential) measures the antioxidant potential of alkaline water. ORP performance dependent on tap water quality

UV Light Disinfection

Used to kill bacteria, cysts, and viruses. Makes water safer.

Vitamin C Ceramic Block® Filtration

Filtration that uses vitamin C in a ceramic matrix, the only filtration technology that is effective against chlorine and chloramines.
