What do you think about me drinking straight from a water filter because I don't want to wash a cup?
For what reason do you not want to wash it?
I think it's healthier than to wash the cup.
Its fine to drink water any way you would like to. However, the tap is probably not any cleaner then a cup would be. The tap is not often cleaned while a cup can go through the dishwasher.
What are you talking about? I don't want to wash that cup, it's gross.
It's fine to drink water from a filter. It's just important that you are not drinking water from a dirty container or putting your mouth on a water filter that others have to use.
