It's great that you posted this. I think 'buying' water when the tap water is clean is madness. It is sad that Uber actively encourage their drivers to provide bottled waters to passengers. The most rediculous part is that bottled water is often more expensive than petrol and has just been pumped out of the ground and bottled. It's just water!!
I bought small bench top water filters for each of my listings that cost about $50. They came with 2 filters that are each good for about a year. To me the water tastes pretty much the same from the filter as straight out of the tap but the guests get kind of excited and think it's great.
The fridge in my 60's themed apartment has a Tupperware water jug actually from 1967. So here we are over 50 years later and it's still being used. Totally Dolpin or Turtle safe.
