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

7-Stage RO Water Filtration System for Home - 75GPD with Food-Grade PP & POM Materials

This 7-stage RO system prioritizes safety and performance, using food-grade materials to deliver pure, uncontaminated water. The system’s PP housing (stage 1-5) is BPA-free and NSF-certified, while POM quick connectors (stage 6-7) prevent leaks and chemical leaching. The filtration process starts with PP cotton (stage 1) to remove sediment, followed by GAC (stage 2) and CTO (stage 3) to eliminate chlorine and odors. The 1812-75G RO membrane (stage 4) removes 99% of contaminants, and stage 5’s coconut shell carbon polishes taste. Stages 6-7 add mineralization filters to reintroduce essential minerals, creating water that is both pure and nutritious.
