Aqua-Ionizer Deluxe 5.0
Score: 78/100
pH Under
Score: 65/100Rankings

The Aqua Ionizer Deluxe 5.0 is a versatile countertop water ionizer offering a wide pH range and strong antioxidant properties with -600mV ORP. Its main trade-off is the high upfront cost and the requirement for adequate water pressure to maintain flow. It is best suited for health-conscious users who value self-cleaning convenience and are willing to invest in premium maintenance.

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.
