I’ve recently started using a Neti Pot, just in the past couple days. I’ve been using it at home while here for Thanksgiving Break. I’m going back to college on Sunday.
There is a difference between the tap water here and at school. At school I think there are a lot of minerals in the water; when I boil water in my electric kettle I frequently get crusty buildups on the metal on the bottom. And I get chalky residues on glassware if there was a little water at the bottom and I let it evaporate. At home none of this happens. I drink filtered water at school from a Brita I keep in my fridge.
Would it be safe to use that tap water when I go to the bathroom to use my Neti Pot? Or should I microwave filtered water? Or should I buy bottled water for use in my nasal cavities?
