The Cube Air Freshener by Chikuno comes from Japan and really improves daily life. It is made of bamboo charcoal which has the pleasant habit of clearing the air surrounding it and maintaining a constant humidity and all that without spreading a smell itself. That's why the Cube is especially good for closed rooms such as bathrooms, cars, or fridges. You should use one cube per cubic metre of air. The Chikuno Cube is found in almost every fridge in Japan.
Smells (strictly speaking ammonia, formaldehyde and methylbenzene) are simply absorbed. The big effect of the little cube is made possible by the property of bamboo charcoal, which can only be seen under a microscope. Countless holes create a structure which reminds you of a bee hive. So one gramme of charcoal has a surface of over 300 square metres storage capacity: more than three football fields. And all that happens to 100% ecological conditions!
The Chikuno Cube should be “drained“ after one month. It has to be put under direct sunshine for a few hours to do this, so that the store is freed and can then continue its work. As the natural minerals are soluble in water, the cube cleaning process should be dry.
