Excellent background article on how activated carbon/charcoal destroys odor

And why a sufficient quantity and forced air is key.

Summary of article on activated carbon and cat odor:

Activated carbon:

  • Has a capacity for virtually any vapor contaminant. It will adsorb some of almost any vapor;
  • Has a large capacity for organic molecules, especially solvents;
  • Will adsorb and retain a wide variety of chemicals at the same time;
  • Has an extremely large capacity to destroy ozone catalytically. Ozone is a major component of smog;Works well under a wide range of temperature and humidity conditions;
  • Adsorbs odors and chemicals preferentially to moisture. It is not a desiccant and will release moisture to adsorb chemicals;
  • Can be used as a carrier of one material to attract and hold or react with another material;
  • Is inert and safe to handle and use; and
  • Is available and affordable.
