I must admit i do prefer filtered water which i do myself from the tap .I have a filter jug in my fridge which i fill up every morning and i really can taste the difference once its been through the filter ..But i do think the bottled stuff is a complete rip off and whose to know if it is filtered or not ? the taste of water changes form area to area, so if im off out for the day and need to take water i always put it through my filter jug first and bottle it up
