Is it better to use activated carbon or desiccant for moisture and mildew prevention?

It is best to use desiccant to prevent moisture. For example, when we buy shoes, we usually find a small bag of white things in the box of shoes, that is, desiccant.

The main function of activated carbon is adsorption, and the microporous structure of activated carbon has a good adsorption effect on odor, which can be used to remove unfriendly odor in space. We usually put some activated carbon in wardrobes, cars and refrigerators (some people put grapefruit peel in the refrigerator to use the micropores inside grapefruit peel to absorb odor), the main purpose is to let activated carbon absorb odor.
