I live in an apartment, and there's cigarette smell coming from the bathroom vent (probably from a neighbour who smokes). I'm wondering is it advisable to block the bathroom vent to block the smoke smell? Can a dehumidifier replace the bathroom vent?


The bathroom has no heaters. The vent is not a fanned vent, so far I believe it's a shared vent (since I'm smelling the cigarette, that wasn't there when I first moved in, so the smell must have came from a neighbour who smokes, which entered the share ventilation system)

Edit (2nd)

Apparently I mistook the problem, it's just an old building with a broken ventilation system (as I originally thought it was a shared vent), the landlord suggested that I duct tape the vent until it's fixed.

do you have a fuel besed water heater in there? if so you shouldn't block of the ventilation – ratchet freak May 24 '12 at 15:32
Do you have another way to ventilate the room like a window or skylight you can open? – Niall C. May 24 '12 at 16:29
Complain to the landlord and just leave your vent running 24/7. That's probably illegal to have shared ducting.. – kavisiegel May 24 '12 at 16:44
Does the vent suck or blow? If it blows, it's an HVAC vent. If it sucks, it's an exhaust vent. If it does nothing, it's useless. – Tester101 May 24 '12 at 17:36
Are you Sure there is no air movement? Hold 1 square of toilet paper up to the vent, to make sure. – Tester101 May 24 '12 at 18:03
