Andrea is an air purifier that optimizes the use of a living plant to filter the air. The device uses minimal electricity to circulate air through the natural filtering systems of the plant in the most effective order. The system shows attention to detail in the technical design, but might benefit from similar attention to its impact on home decor. After all, the premise of the design is that homeowners like the look of indoor plants, which is somewhat lost in this incarnation. This device is organic in its intuitive concept – most people understand that plants filter air. Finally, the system feels human in its simplicity of use – just add a plant and turn it on. Overall, this is a desirable concept that could develop into a functional and attractive appliance.
