And because the exhaust fan is operated in one direction, the indoor air can only be discharged, and the length of the pipe during operation is weakened, so it is only suitable for installation in a living room with good air circulation, and is not suitable for installation in a kitchen or a bathroom; The huge noise generated during its operation makes it impossible to install in the bedroom, otherwise it will affect people's rest.
