French designer Mathieu Lenhanner together with Harward professor David Edwards have come up with a organic air purifier , powered by a houseplant.

The clever invention goes by the name of ANDREA and will be on sale from October. So how does it work?

The plant absorbes the air through its leaves and roots and the filtered air provides a more environmentally friendly option to the standard air purifier. It works best in a room as big as 40 m2 and it is very easy to maintain as the plant requires simply watering.
