Onda is a decorative textile piece that purifies the air.

It is constructed of fabric with a thin coating based on copper-doped titanium dioxide. When combined with this chemical coating, the textile uses daylight to create a reaction with pollution such as soot and odor, transforming them into harmless water molecules. Users can track the air quality by lightly pressing on Onda’s fabric. This activates a light that will remain slow and calm while the air is clean, but become quick and frenzied when sensing pollution. Users can also momentarily boost air purification by pressing and holding the piece, lighting the frame to emit ultraviolet light, the most efficient method of rapid air purification. With interchangeable textiles and designs, Onda unites life-enhancing technology with personal expression.
