This process takes approximately 45 minutes.

If you have followed these steps then you now have a clean cooler and have taken an active role in preserving the quality of the equipment you use to dispense your bottled water. “Cleaning instructions are care of the IBWA (International Bottled Water Association) pamphlet #05-04.”


You’re not alone! Bottled water companies don’t say anything about this cleaning protocol. If they did then no one would sign up because who has the time to go through all that trouble! 

The American Society For Microbiology, Tufts University, Brookhaven National Laboratory, Health Canada, etc., ALL agree regular sanitization should take place to reduce bacteria and biofilm. 

You may have a love-hate relationship with salad BUT we at Hydr8 would bet most people can do without salad in their water…

Ultimately, we believe water should be there to help you do your job NOT be-your-job. You, your team & your family have better & more important things to do, don’t you?
