Yup. Gases like CO and ozone (the really bad actors) aren't absorbed by activated carbon to any appreciable extent. The other vapors that activated carbon will absorb are really that prevalent.

Activated carbon filters also have a limited life. They need to be replaced regularly or they become saturated with what ever you are filtering out. Then they are worse than useless.
