Is the air pollution in Huiren Sunshine Garden serious? Black smoke is emitted from the surrounding factories.

Hello, landlord. Generally, a community like yours with factories around it is worried about not opening the window but wanting to breathe fresh air and ventilate the room.

Gunai fresh air system only needs to open a hole with a diameter of 85mm in the wall, even if the outside is polluted, it will not affect the ventilation and healthy airflow in your room. At the same time, you don't have to put up with noise!
