How to Reuse Activated Charcoal

Quck answer

Activated charcoal can be effectively reused in various ways. Firstly, it can be used as a natural air purifier by placing it in a breathable bag and placing it in areas with odors or excessive moisture. Secondly, it can be used as a water purifier by placing it in a water filter or mixing it with water and then filtering it. Thirdly, activated charcoal can be used for skincare by mixing it with other ingredients to create face masks or scrubs. Lastly, it can also be used for gardening by mixing it with soil to improve drainage and absorb toxins. Reusing activated charcoal helps save money and reduce waste.


Activated charcoal is different from the one used for cooking in a barbecue pit. The porous nature of activated charcoal allows it to absorb odors from the air. To reuse your activated charcoal, also known as activated carbon, you can remove the odors and reactivate it by baking it. However, it is recommended to reuse the charcoal only two or three times, as it is difficult to completely clean the pores of the activated carbon using household appliances. You can find activated charcoal in the aquarium-supplies section of pet stores or in garden centers.

Step 1

If the activated charcoal is damp due to absorbing moisture from the atmosphere, let it dry completely.

Step 2

Preheat the oven to 300 degrees F and spread the charcoal in a single layer on a baking sheet.

Step 3

Place the activated charcoal in the oven and bake it at 300 degrees F for one hour to remove odors and impurities.

Step 4

Allow the activated charcoal to cool completely before placing it in an open shallow dish in the desired area to eliminate odors.
