The 'Drop by Drop' Home Water Purifier is a more natural approach to water purification that aims to remind the drinker of the processes that exists in nature.
Designed by Pratik Ghosh, the unit consists of a terrarium that works to provide water to plants. This water is then evaporated back into the environment so that it can be enjoyed by the user. This enables the water to go through the entire natural process in order to provide the user with the best quality water possible -- all without the use of electricity or appliances.
The 'Drop by Drop' Home Water Purifier is reported by the designer to purify up to one glass of water per 12 hours, which makes it an ornate, yet mostly artistic piece.
