Which desiccant has anti-mildew effect?

To summarize, here are several common desiccants and their effectiveness in preventing mildew:

Silica gel desiccant: The moisture absorption rate is about 30%. It can reduce humidity through physical adsorption and help reduce the breeding environment of mold.

Carbon-oxygen desiccant: The moisture absorption rate is between 50% and 70%. It controls the humidity through physical adsorption and can reduce the breeding environment of mold.

Fiber desiccant: The moisture absorption rate is higher than 70%, which can reduce humidity more effectively and prevent the growth of mold.

Calcium chloride desiccant: The moisture absorption rate is as high as 200%-300%. It absorbs moisture through chemical reactions and can quickly reduce humidity and effectively prevent the growth of mold.
