Alkaline water systems work by using either electrolysis (water ionizers) or mineral filters to increase pH levels and create water with higher alkalinity than regular tap water. The goal is to produce water with pH typically between 8.5 and 9.5, which proponents claim offers various health benefits.
Reverse Osmosis with Mineral Addition: Multi-stage filtration that removes contaminants then adds back minerals for alkalinity. Most popular for home use.
Water Ionizers: Use electrolysis to separate water into alkaline and acidic streams. Offer adjustable pH levels but cost more.
Mineral Filters: Simple filters that add alkaline minerals to water. Less expensive but limited pH increase.
Countertop Units: Portable systems requiring no installation. Perfect for renters or temporary use.
✅ Pro Tip: Test your water pH before and after installation to verify the system's effectiveness. Most systems include pH test strips for this purpose.
