Firstly, activated carbon can effectively adsorb formaldehyde. Formaldehyde is a common indoor harmful gas, and long-term exposure can pose a potential threat to health. The large pore structure and highly developed specific surface area of activated carbon can adsorb formaldehyde molecules and fix them on its surface, thereby reducing indoor formaldehyde concentration.

Secondly, activated carbon has good adsorption stability. The adsorption performance of activated carbon is long-lasting and stable, and it can maintain its ability to adsorb formaldehyde for a long time. This means that it can continuously purify indoor air, maintain a lower concentration of formaldehyde, and provide people with a healthier living environment.
