The air outlet will discharge all kinds of gases, which may have a sense of suffocation. If the courtyard on the first floor is too close to the public air outlet, it may be affected by suffocation, thus affecting the gas field and feng shui at home. In addition, the air outlet may also emit odor or other harmful substances, which may also have adverse effects on the environment and health.
Therefore, if you can choose, try to avoid choosing a house that is too close to the public air outlet. If you have bought a house on the first floor, it is recommended to set up a screen or a plant wall in the yard to block the gas and suffocation discharged from the air outlet. In addition, some plants can be placed in the yard to absorb harmful substances in the air and purify the air.
