Ultra-Pure 7-Stage Reverse Osmosis Water Purifier 75G - Home Drinking System with Coconut Shell Carbon & 3.2G Pressure Tank

High-Capacity 7-Stage RO Reverse Osmosis Water Purifier - 75G for Home & Small Office Use

Ideal for both homes and small offices, this high-capacity 7-stage RO system delivers 75GPD of pure, mineral-rich water to meet daily hydration needs. The system starts with a 100g PP cotton pre-filter (stage 1) that traps more sediment than standard 50g filters, followed by stages 2-3 (GAC, CTO) to remove chlorine and organic contaminants. The 1812-75G RO membrane (stage 4) removes 99% of heavy metals and microbes, while stage 5’s coconut shell carbon enhances taste. Stages 6-7 add mineralization filters to reintroduce electrolytes, making water suitable for direct consumption and beverage preparation. The 3.2G pressure tank ensures on-demand access, and the system’s 12kg gross weight (including packaging) is optimized for international shipping.
