Do air purifiers work?

k

Hi all,

So i moved to a new apartment and even though there's no smoking in the buiding allowed, my apartment constantly reeks of secondhand smoke. (I have contacted the property manager but essentially he goes and gives the neighbors a slap on the wrist, they'll stop for a few days and then start smoking indoors again.)

Does anyone have any experience with air purifiers? Do they work? I just want to be able to breathe decent air.
