Apart from the wind, "everyone thinks that the air is better at higher levels, which is in fact wrong," points out Hu Pao-lin. It is true that carbon-dioxide is relatively heavy, so along with dust it drifts towards the ground, meaning that the higher you live the less problems you get from carbon-dioxide and dust pollution.
