It is effective in removing dirt, rust and sand particles. Stage 2: Carbon Block Filter( GAC filter) : It takes out 99% of the chlorine and organic chemicals. It provides enhanced reduction of taste, odor, and color. Stage 3: 5 Micron Sediment Filter( CTO filter ) : With only 5 micron rating, provides effective filtration to protect your membrane. It provides for improved membrane performance up to 95% of TDS rejection. Stage 4: Reverse Osmosis RO Membrane( Japan Toray ro membrane) : A thin film composite ( TFC) high quality membrane that processes 50 gallons per day. It remove the following hard water contaminants that may be present in your water: lead, cooper, barium, chromium, mercury, sodium, cadmium, fluoride, nitrite, nitrate, and selenium. Stage 5: Post Carbon filter( T33 RO water filter) : This carbon post filter removes objectionable tastes and odors to enhance the quality of your drinking water. We are using coconut shell post carbon to guarantee the taste of water. Stage 6: UV lamp: UV with Stainless steel shell and plastic shell for choice Advantage and features: 1, all products original installation. 2.water filter media: 100% coconut carbon filter not any coal carbon filter. 3, large tests before selling 4, CE, RoHs, member of WQA and IWA certifications 5, independent laboratory ( check laboratory photo as below ) 6, professional produce line and professional inspector professional design team Why is reverse osmosis RO system better? Reverse Osmosis ( RO) drinking water systems include mechanical filtration to remove particles, carbon absorption and absorption to remove chloring, taste, odor and chemical contaminants, as well as membrane separation down to 0.0001 microns. RO membranes remove dissolved solids at the ionic level. No other purification system can provide better removal.
