How Long Should Charcoal Bags Be Kept in the Car Before Discarding?

[Roy]

Charcoal bags should be discarded after 2 to 3 months of use in the car. Over time, the activated charcoal inside becomes saturated and loses its absorption capability, at which point it can be thrown away. Activated charcoal is a microcrystalline carbon material made from carbon-containing substances. It appears black in color, has a highly developed internal pore structure, a large surface area, and strong adsorption capacity, making it a commonly used adsorbent, catalyst, or catalyst carrier. Activated charcoal can be categorized by raw material source into: wood-based activated charcoal, shell-based activated charcoal, animal bone and blood activated charcoal, mineral-based activated charcoal, synthetic resin activated charcoal, rubber and plastic activated charcoal, and recycled activated charcoal. By appearance, activated charcoal can be classified into: powdered, granular, irregular granular, cylindrical, spherical, and fibrous forms.
