80% of human body is made up of water, which is closely related to human metabolism. Changshou villages all over the world have a common feature, that is, the local water quality is particularly good. This shows that water quality affects people's health.

At present, the mainstream water purification equipment in the market is ultrafiltration machine and RO (reverse osmosis) machine.

The core of RO machine is RO membrane, and its aperture is less than1nm (1nm; 1000nm = 1um； 1000um= 1mm). Water purification is completed by reverse osmosis principle.

The core of ultrafiltration machine is ultrafiltration membrane, and the pore size of membrane is 10nm~ 100nm. The principle is membrane separation technology.

The size of bacteria is larger than 100nm, which can effectively sterilize bacteria.

The filtration accuracy of ultrafiltration machine is not as high as that of RO machine, and no power supply is needed. Simple and convenient, can remove most harmful substances, while leaving some minerals and trace elements.

You can choose St. Lance water purifier, not bad! Use reverse osmosis membrane technology, ultrafiltration membrane technology and diamond activated carbon technology to completely remove pollutants in water.
