Vents in shops and toilets will affect residents in stairs and aisles.

1. Rebuilding the exhaust duct: You can try to change the direction of the exhaust duct in the bathroom of the shop to avoid affecting the staircase corridor of the residents as much as possible. If conditions permit, the exhaust duct can be extended to the outside to reduce the impact on residents.

2. Install activated carbon filter: Install activated carbon filter at the outlet of exhaust pipe, which can effectively absorb odor and reduce the impact of odor on residents.

3. Add sound insulation measures: For noise problems, sound insulation materials can be installed at the outlet of the exhaust duct to reduce noise transmission.
