I discovered an interesting natural product to maintain kitchen freshness by increasing the longevity of produce in the refrigerator. Not only does this cube absorb ethylene gas in the refrigerator, it can also be used to absorb smells in other small spaces around the house. What an interesting product:

What is it?
This neat little black cube efficiently purifies and refreshes the air in smaller spaces as it reduces odours. Try it in places such as drawers, closets, the car or your refrigerator.
Moreover, it can be used to keep food fresh by absorbing ethylene gas – try placing it in your fruit bowl and it will stay fresher for longer.
6 x 6 x 6 cm
Tested and documented effect by Danish Technological Institute.
What is it made of?
Kuro Cube is made from powdered and compressed White Charcoal.
This is the highest grade of charcoal available with an extremely high carbon content.
The raw material is Korean oak and the powdered White Charcoal is organically produced and handcrafted in Korea.
How to use?
Remove the plastic cover and place your Kuro Cube straight into your fridge or in any small space you want to deodorize.
Occasionally exposing your Kuro Cube to sunlight allows it to dry out thoroughly and regain its ability to absorb.
Do not use a microwave oven for this purpose.
How long does it last?
Kuro Cube remains active for one year.
How to recycle?
A used Kuro Cube is an excellent fertilizer. Just crush it and mix with potting soil, in order to nourish it and regulate its PH levels.
