Backdraft through toilet ventilator in flat
Posted: Wed May 26, 2021 12:43 pm
The toilet ventilator in my flat is hooked up to the building's ventilation shaft. The neighbour below us is a smoker and her cigarette smoke enters our toilet through the ventilation fan. I'd much appreciate feedback on what can be done to prevent the smoke from entering our toilet. I understand that a shutter fan may be an option but am unsure if it's the right solution.
