7. Filtration Process and Certification
The Waterdrop M6HG employs an advanced 8-stage filtration system to ensure comprehensive purification and mineralization.
Figure 7.1: Advanced 8-Stage Filtration with added minerals. The stages include Pre-Carbon Filter, Scale Inhibitor, PP Cotton, 0.0001μm RO Membrane, Activated Carbon Filter, Mineral Infusion Layer, PP Cotton, and UV Treatment. This process reduces contaminants like Fluoride, PFOA, PFOS, TDS, Chlorine, Lead, Heavy Metals, Chromium, VOCs, Cadmium, and other impurities.
After RO purification, the system adds essential minerals like calcium, magnesium, and potassium to improve taste and provide balanced daily drinking water.
