For comparability, the common bathroom seat has about 1,200 CFU/sq cm. Meaning in some instances, your water bottle may very well be 700 instances dirtier than your bathroom.

And should you’ve ever left your water bottle within the automobile in a single day, you understand it might probably begin smelling funky. That’s not simply “outdated water odor” — that’s bacterial progress.
