I didn’t know that. We use zero water filtration, but now I’m noticing what looks like mold on the inside of the container. Faint little white clouds. I’ve taken to putting a few drops of bleach in the receptacle. Our water is not fit to drink without filtration.
You should look into chlorine dioxide as a disinfectant. It’s not as toxic as bleach (sodium hypochlorite).
You can get tablets right from Amazon, and they are for water purification.
