Drop By Drop is a plant-based water filter that works as a mini Amazon

Cool concept! Via Dezeen.

Drop by Drop houses plants under a glass dome. Pipes allow water to be added in to be purified, and later collected. The system is designed for grey water – which comes from washing machines, sinks and baths.

A light within the dome triggers the plants to photosynthesise and transpire, so water is drawn through the roots and onto the leaves, where it enters the air as vapour.

A pump controls the system’s airflow and creates a vacuum to further expedite transpiration.
