1, formaldehyde will float in the decoration next door, because the air is flowing, and formaldehyde will spread with the air.
2. However, this formaldehyde content will be relatively low, and the solubility will be diluted when it is blown outdoors, which will basically not affect human health.
3, so don't worry too much, you can close the doors and windows during the renovation next door, or plant more green plants indoors to come to in addition to formaldehyde.
All of the above are about formaldehyde decorated next door. I hope it will help everyone.
