1st PP-10A PP fiber filtration wipes off impurities, algae, silt, sediment 2-3 months
 

2nd GAC-10A GAC filtration wipes off residual chlorine, THM's, unpleasant smell, pesticides, chemical poisons 3-6 months
 

3rd CTO-10B Block carbon remove the heterochrosis, odour, chroline and other materials which are harmful to health.To improve the taste, Will use the micropore of the active carbon filter to holdback the microgranule,micro colloid and micro suspended materials. To make the water which into the RO membrane is suitable so as make the lifespan of the ro membrane are longer

  3-6 month
 

4th RO RO membrane,remove the micro impurities,colloid,metal,bacterials and so on,only

left the water molecule and dissolved oxygen,output water is purity water

  12-24 months
 

5th T33A Post active carbon(T33),improve the PH,avoid the second contamination

6th stage: Mineral ball cartridge, add mineral material to the purified water
