Everyone needs to get a Brita Water Filter! save money and the environment.
I convinced my parents to get a water filter for the house, and it was probably one of the best ideas I’ve ever had. My brother and I carry water bottles with us everywhere, and we’ve gotten our mom into carrying one.
The only edit I would make to this is to remember to add the cost of replacement water filters, though I’m sure it’ll still be far cheaper than bottled water.
