If the nurzle for your RO spigot got contaminated with something that liked noses after being shoved into somebody's drink... it might start growing up there. I prefer to only fill the bottles with boiling liquid when dissolving the salt. I use a water boiler. Then you have to wait for it to cool. 20-30 sec in the microwave will bring it back to head temperature. What I REALLY would not use is an old Britta that's been accumulating goo for the last year. Fungus is bad, hard to kill, and will eat your brain. Do you have sourdough, kombucha, or any other weird smells in your fridge? Keep it outta there!
