What air purifier brand/model to filter smoke?
I have neighbors who are heavy smokers. Sometimes even with the door closed, will still smell cigarettes smokes. Will air purifier help? If so, what air purifier brand/model helps?

Xiaomi air purifier, get it on Qoo quite affordable. But again, I will speak to the neighbour to see if they can help by closing their door etc.
