Plenty of clean water for drinking and cooking should be everyone's goal. Bottled water is expensive and of questionable value. Costco has a killer under-sink filter that is cheaper and better than anything available, trapping pathogens as well as microscopic debris. And it comes with a year's supply of filters, and a really handsome chrome water spout for your sink, all for about $150.
The Pur or Britta water pitchers with filters are a far better investment than bottled water is, except the price of the pitcher itself is ridiculous, especially for a piece of plastic that breaks easily.
Paying someone to filter tap water and supply it to you in bottles is crazy when you can use a pitcher or the Costco filter to make your own.
Drinks lots of water, but 8 glasses a day is a little much I think, unless you have a job or sport that makes you sweat profusely. Water engorges your skin and muscle cells, plumping them up, making skin softer and smoother, and giving muscle a more toned appearance.
