How do odour sprays like Febreeze or Lysol eliminate odours in the air?

I understand adding a good smell but is there chemicals in it that destroys the odours from whatever youre trying to rid the room of?

These work due to chemicals known as cyclodextrins. 

Typically a number of glucose molecules in a ring. 

Small aromatic molecules are able to become trapped within these rings due to strong intermolecular between the inside of the ring and the small aromatic. 

This takes it out of the air and out of your nose!
