A highly absorbent type of charcoal, activated charcoal has been used as a natural purifier in Japan since the Edo period (1603 – 1868). It naturally pulls moisture from the air and purifies drinking water, all without the use of plastic filters.

Wedding this ancient craftsmanship with a minimal design, the Chikuno Cube is infused with activated bamboo charcoal from Kyoto, where is home to an especially sturdy and long-lasting species of bamboo. In a specialized kiln, bamboo branches are burned and carbonized over a period of 2 to 3 days, then blasted with heat and starved of oxygen. When the branches reach roughly 2300°F, they are taken out, rapidly cooled, and smothered with ash. This process carbonizes the bamboo, creating thousands of microscopic cavities that chemically bind with ions to attract, trap, and neutralize impurities. The result is a powerfully absorbent natural purifier that neutralizes toxins and contaminants in the air.

Unlike common air fresheners, activated charcoal does not cloak odors. Instead, the Chikuno Cube absorbs scents and neutralizes them, essentially clearing the air from pollutants such as formaldehyde and toluene. The cube itself won’t acquire a smell even as it pulls odors from the air.

The effects of activated charcoal are most powerfully felt when placed near strong odors like smoke, fish, mildew, burnt food, sweat, and trash. Beyond banishing odors, the Chikuno Cube can also be used to treat particularly damp spots in the home, for instance, musty basements and mildewy bathrooms. To ensure the cube stays absorbent, we recommend placing it under full sunlight for six hours every month. The sunlight will recharge the charcoal’s absorbency and keep the cube as good as new.

Though most people use the Chikuno Cube around the house as a preventative measure, we'd also recommend placing it strategically near certain areas of need:

  • Near the oven to dispel the smell of smoke or burnt food.
  • Inside the refrigerator in place of a box of baking soda.
  • In a small bathroom or powder room to prevent dampness and mildew.
  • Near a litter box to absorb unpleasant odors.
  • Inside a car to ease the smell of exhaust.
  • In the shelf of a linen closet to keep laundry smelling fresh.
  • Tucked in a corner of your car to keep the seats smelling fresh.

Unlike plastic air refreshers, the Chikuno Cube is 100% recyclable and can be re-purposed as soil compost. After 12 months of use, break the cube into bits (you can use a hammer) and bury them in your garden. The charcoal-clay bits will help stimulate natural growth and nitrogen production. The tiny pores in the charcoal help aerate the soil, increasing microbial activity and creating healthy natural soil for your beloved plants.
