Chanitex purifier products categories are abundant, you can choose referring to product parameters. If you have measured the installment size.  You can tell us and we could recommend suitable products.

RO water purification uses RO membrane filtration technology. RO membrane chooses selective permeable membrane, its filtration accuracy can reach 0.0001 micron, it can intercept heavy metal ion which is harmful in the water, incrustation that may causes gall-stone, and discharge these intercepted heavy metal, incrustation, bacteria and pollutant with wastewater, the hydrone in the water remains to be drunk. As water goes into human body, what can be absorbed keeps and what can’t be absorbed is discharged from human body. Therefore, RO membrane filtration has the good reputation of  extracorporeal kidney.

Ultra purifier use ultra membrane technology. Ultra membrane filtering accuracy is relatively lower, it’s only 0.05-0.1 micron. Most of the material in the water such as suspended solids, atom, bacteria can be hold back, comparing to RO membrane, the disadvantages are obvious : first, the heavy metal ion that is harm to human body can not be hold back; second, incrustation can not be wiped out, the water that is filtered has white cottony materials after boiling; third, the poisonous organic materials such as tetrachloromethane and trichloromethane can not be wiped out absolutely

Therefore, we not suggest that drink directly the water that filtered by ultra purifier.

Water purifier’s wastewater proportioner is international standard device, its discharge proportion has something to do with tap water pressure, tap water quality and RO membrane’s working condition. The conventional device’s proportion is 1:3. In fact, waste water is not completely wasteful. We can collect it by bucket to mop the floor, water the flower, flush the toilet and so on.In addition, A.O.Smith (Shanghai) water treatment products successfully research and develop side stream RO membrane which makes the proportion of water and wastewater is 1:1, it is No.1 in the industry. 

No , the harmful materials are filtered completely in the purified water, and the purified water is stored in the sealed pressure barrel to insure the water quality pure and clean. However, we suggest that  you purify water when you want to drink , if like this ,it can increase the fresh and be good to health. In addition, A.O.Smith  develops various tankless purifiers that can purifying water when you want to drink.

The health certificate about water ‘s full name is” Health licensing certificate about health and security of drinking water products”, it is awarded to manufacturing drinking water products corporate by government, it is the only authoritative document that marks the water product is healthy and secure. Nation indicates that in the laws and regulations :  the instruments such as water transport and distribution, shielding materials, chemical products , water treatment units and drinking water disinfection equipment that referred with the water in the process of manufacturing and supplying drinking water are drinking water health security products, referring water products is called for short. Therefore, health licensing certificate is not awarded by some association or organization but government. It is supervised and executed by department of health with a set of strict approval procedures.
