Charcoal Odor Absorber: Are Their Effectiveness Overrated?
Charcoal has some porosity to be used as an absorbent, but in order to be effective it has to be exceptionally porous, that is why you need activated charcoal to better absorb odors. Activated carbon is basically charcoal that has been processed through a chemical/heat (like the sun) treatment to be activated, this treatment causes in the charcoal an extreme porosity.
