Avid water drinkers are going to dig the Metamorphose Filter. Nadim Inaty's conceptual water filter is designed as to turn normal PET bottles into classy and sleek filter bottles. Water bottles with filters are becoming more and more common nowadays. These bottles tend to fall into two categories when it comes to design: cheap and efficient and ridiculously efficient/good looking.
The Metamorphose Filter is a hybrid of these two design philosophies. The sleeve comes with an included filter that doesn't need to be removed in order for the bottle to be used after filtering is complete.
The Metamorphose Filter would be a great middle ground for those who want a nice filter bottle without having to pay the not-so-nice price tag.
