Devices that dispense water with a pH higher than neutral (7) are becoming increasingly common in homes and workplaces. These appliances typically utilize a filtration process involving materials like calcium and magnesium to raise the pH of the source water. A standard unit often features a reservoir, filters, and a dispensing mechanism, potentially including temperature control options for chilled or hot water.
Proponents suggest potential health benefits associated with consuming water with elevated pH, such as improved hydration and acid neutralization. While research in these areas is ongoing and conclusive evidence remains debated, the perceived advantages have contributed to the growing popularity of these appliances. Historically, access to alkaline water was primarily through bottled sources. The advent of these in-home and office appliances represents a shift toward more convenient and potentially sustainable access.
