Air Purifiers

and the masks we bought you can still smell the smoke through the mask. We also have two air filters in the bedroom but they don’t really work as well as I would like them to. He knows he should stop smoking but he has tried and it didn’t work out.
PLEASE stop the " tell him to go outside" it is below zero here. I want info on air filters/ purifiers and face masks only.
Again stop with the lessons, I do not want a lesson, if I did I would have asked for a lesson. Everyone has an addiction have t be smoking, coffee, pop, sex, internet, tv or even drinking. So please stop " being a teacher" and give me the answers I was looking for and not a speach.
