Activated alumina and silica gel are both effective desiccants, but their performance depends on the application. Activated alumina generally has a higher moisture adsorption capacity at high humidity and can also remove certain chemicals like fluoride, while silica gel is often preferred for general moisture control due to its stability and reusability. Therefore, which is "better" depends on your specific needs.
