The 4-stage Reverse Osmosis is the ultimate system for those who demand the purest 　water for drinking and cooking. Simple filter systems are fine for improving taste and smell 　but they can't remove many of the impurities found in our water. That's where the 　advanced performance of the Reverse Osmosis (RO) process can help.　



　he semi-permeable membrane allows only pure water molecules to pass through leaving the 　impurities to be washed down the drain, leaving you with the purest water on tap with up 　to　98%　of　contaminants　removed.　



　Automatically and manually wash RO membrane ;

　Manually wash RO memebrane with chemicals on machine;

　Machine automatically stops when high water level of purified water, and runs when low 　　level ;

　Multi-stage pumps protect the machine when lack of water;

　Protection in such cases as no power, lower pressure, higher pressure, shot circuit, 　creepage, etc.;

　Large eletric current, creepage protect and soon;
