High Performance Filtration

Stage 1 (CF consists of PP & CB): PP sediment filter (10-15μm) blocks and reduces colloid, sediment, rust, large particles, and suspended impurities; Carbon block (5-10μm) removes residual chlorine (≥85%) and COD (≥25%);
Stage 2 (RO): RO membrane (0.0001μm) can get rid of dissolved solid ions such as heavy metals, and microorganisms such as coliform bacteria. The desalination rate is >95%. 4 models of 75G,400G,500G, and 600G for you to choose from. Both Toray and Dow are available.
Stage 3 (CB): Post carbon block (10-15μm) can remove residual chlorine, carbon tetrachloride, methane, colors, and odors with a removal rate of up to 85% in the whole process, further polish purified water and balanced pH with minerals add back, which brings you odorless and refreshing water.
