The habits of using water every day

Tap water meets Vietnam's domestic water standard which is QCVN 01: 2009/BYT. However, you should note that:
  • To reach your home, tap water has gone a long way in the plumbing system. On its way, there may be a lot of impurities such as dirts, rusts, leads,... and even bacteria. Therefore, Cleansui recommends that you should not drink tap water directly without going through a reliable water purifier.
  • Drinking boiled water is an old habit of the Vietnamese people. However, did you know that boiled water can get re-infected after 2 hours, and after 24 hours, the amount of bacteria will continue to multiply? Therefore, Cleansui recommends that water should be consumed within 2 hours after boiling or you should use water filtered from a reputable water purifier.

Although using 20 liter water bottles is considered as a safe solution, there are some disadvantages compared to using Cleansui water purifier as follows:
  • It takes time to have water ready, you have to wait for delivery service.
  • The process of bottling & rinsing may not be guaranteed, the risk of re-infection is high due to the reuse of plastic bottles -> Microbiological criteria is not guaranteed.
  • Water bottles at some unreliable facilities may have sediments or solids at the bottom of the bottles due to the presence of unexpected objects in the production process -> Physicochemical criteria are not guaranteed.
  • In addition, the cost of using Mitsubishi Chemical Cleansui water purifier (using EUC2000 cartridge ) is 495 VND/ liter, cheaper than using water from a bottle with the cost in the range of VND 1,000 - 2,500/ liter (type VND 20,000 - 50,000/ bottle of 20 liters).
