For visibly clearer water use the Frieling Clear Water Fan. Tea is only as good as the water it is made it. Tea connoisseurs know the problem; boiling hard water results in cloudy tea with an unpleasant surface film, impaired taste and an accumulation of line in the water kettle. The Clear Water Fan removes hardening agents (calcium and magnesium) from tap water and in exchange adds ph-neutral potassium for a difference you and see and taste. Savor coffee, tea and plain water they way they were meant to taste.
