When you’re fighting tough litter box odors, the best result is no scent at all. For optimal, odor elimination, you might try cat litter that is specially formulated with activated charcoal. We’ve researched this super absorbent, odor-eating element to tell you how it works.
What is Activated Charcoal?
Activated charcoal, or activated carbon, is a carbon-rich powder comprised of microscopic pores. It is created by heating carbon-rich materials such as coconut shells, wood, or coal to extremely high temperatures (1,110°F -1,650°F) and gathering the remaining charcoal powder. Activated charcoal has been treated with additional elements to create a more extensive, porous network.
How Does Activated Charcoal Absorb Odor?
Because it is made from porous carbon, activated charcoal is highly absorbent. Microscopic pores covering the surface area of each charcoal particle attract molecularly smaller solids, gasses, or liquids from the air to trap them inside. Quality activated charcoal can trap up to 50% of its own weight, making it a useful absorbent material.
Foul-smelling odors, like those associated with your cat’s litter box, are the result of a high concentration of organic gas, or vapor, that lingers in the air. Simply placing activated charcoal in the vicinity of the odor is enough to let the absorption power begin to take effect. The activated charcoal will pull the odorous gas from the air and trap it in its pores.
Cat Litter with Activated Charcoal
Eliminating odor from your cat’s litter box is easy when you select a cat litter that contains activated charcoal. Some odor-eating litters manufacture charcoal directly into the litter granules or pellets. Others mix the charcoal into the already formulated granules or pellets.
Alternatively, you can purchase an odor eliminator product that contains activated charcoal separately to be added to any cat litter. If you’re searching for odorless cat litter options, keep reading to see our list of the best six cat litters and additives with activated charcoal.

Carbon Filter Litter Boxes
Although activated charcoal is non-toxic and safe to use near your kitten, cat, other pets, and children, loose charcoal mixed with litter can leave remnants of black dust. You might try a carbon filter to purify the air in the vicinity of your cat’s litter box to avoid excess cleaning.
