Winner of the Japanese Good Design Award, 2008

The Chikuno Cube House (small) includes a wooden geometric base for display. Winner of the 2009 Japanese Good Design Award.

The Chikuno Cube is a natural air purifier made from an ultra-fine powder of activated bamboo charcoal and clay minerals. Its micro-honeycomb structure filters air particles, while its charcoal make up naturally absorbs moisture, odors, and pollutants. This eco-friendly cube works best in enclosed spaces like small bathrooms, cars or refrigerators, and can be used up to one year. Set it in any small space and feel the air become naturally pure and wholesome. Covers surface area of 17 sq. ft.

Care: To refresh the cube, expose to direct sunlight for six hours each month. This releases the absorbed odors and makes it ready for reuse. After a year, recycle it as fertilizer by breaking apart the cube and planting the bits in the soil or litter.
