The Bobble™ bottle is a revolutionary new concept in BPA-free water bottles. Unlike other BPA-free bottles, the Bobble actually incorporates a built-in carbon filter that is guaranteed to provide 150 liters of pure water — which equates to about 250 bottles of water. The Bobble™ is BPA-free, made from recycled plastic and the super stylish carbon filter comes in six different colors and filters chlorine and organic contaminants from regular tap water.
