What a great idea! Not only does this American made, Karim Rashid designed, BPA free water bottle purify your tap water, but it's made from recycled plastic that is also fully recyclable! It contains a filter that lasts for at least 300 uses. When it's finished, you send the used filter to Bobble in a pre-paid postage envelope to be recycled! For only $9.95 (replacement filters $6.95), this is the perfect eco-chic solution for purified water on the go...think of the savings and the good it's doing for the environment!
