designer's own words:Aria - a solar powered kitchen air freshener. Plug in more Aria leaf stalks if you have a bigger kitchen space, or less stalks if you have a smaller kitchen. Running on solar power, the Aria leaves absorb kitchen smoke, ionises and purifies it with fresh smelling air. The solar panels are embedded on the other side, thus making the unit spae saving and independently operated. It's intelligent sensors allow automatic configuration, working doubly hard to clean the air when you cook, or runs on idle mode in other times. Its modular Aria leaf stalks allow more options to be added, and altogether, make your future kitchen, cleaner and fresher smelling. Aria - breathe fresh!
