For me personally, I like to avoid bottled water because of the carbon footprint it takes on the environment. Bottle water is also significantly more expensive than filtered tap water, especially when you factor in waste that happens during production.
Save money buy buying a reusable bottle and filter that will help you lug free-flowing Nantucket spring water while cruising down Interstate 95. My Drinkwell Platinum Pet fountain comes equipped with Carbon filters which will eliminate any potential contaminates while making your pet happy at the same time!
