Score: 65/100Rankings

The Alkadrops Water Ionizer is a home water purification system that utilizes electrolysis to produce ionized alkaline, purified, and acidic water. It features a 3.8-inch LCD screen for monitoring pH and ORP levels and offers seven distinct water settings ranging from pH 3.5 to 10.5. It is best suited for users seeking a home water purification system capable of producing multiple water types for drinking, cleaning, and skincare who need a device that adapts to varying local water quality levels.

The Cosan/USA pH Under is an undercounter alkaline water system that uses a proprietary magnesium-based process to filter and alkalize water without electricity. It offers a fixed pH of 9-9.5 and antioxidant production but lacks detailed technical specifications. It is ideal for users seeking a passive, no-wastewater solution for hydrogen-rich water.
