Dirty Air In The Room

My husband is a heavy smoker. I think he can't stop smoking easily. Sometimes, he is smoking inside the room as well. I don't agree with this but he always agree if I ask him to stop smoking. I think sooner or later, I need to find a service that can clean the air in the house. I feel it so dirty to smell the smoke from the cigarettes. Maybe I should try to call air duct cleaning san antonio and ask them if they can help me clean the air in the room a little bit.
