I have a PUR water filter attached to my tap. When I am at home, I drink from a plastic glass. When I am out, I fill my own water bottle and bring it with me, and wash it out and re-use it later.
When I see that people are still using plastic water bottles they've bought from the store, it upsets me.
From the kitchen sink like a sensible person. I am not one of those nitwits who buys hundreds of little plastic bottles each year wasting money and making more plastic pollution
