Oro is a humidifier designed to operate passively and complement the atmosphere of the surrounding room.

A porous reed draws water upwards from inside the reservoir through capillary action. Six paper petals fold upwards when saturated, similar to how a pinecone opens and closes. This movement serves as a visual indicator that the device is active and reveals a pattern of openings that enable even greater evaporation.

Once equilibrium is achieved, or no water remains in the reservoir, the petals fall back flush with the top surface.
