First of all, you can put green plants in the house, and some harmful gases will remain in the newly renovated house, so as to maintain an appropriate extension of the stay time. We all know that green plants can absorb harmful gases, so it is strongly recommended to increase the absorption of some harmful gases by green plants, flowers and clean water.
In addition, putting clean water in the newly renovated house can also effectively remove harmful gases. You can put a basin of clean water in each room to increase indoor humidity and prevent cracks in walls, roofs and furniture from drying too fast.
Finally, it was cold. After the relocation, the air audit after the heating season should be carried out. Dry air, high temperature, poor indoor ventilation, large core board, hardwood floor, large evaporation, decorative materials, such as formaldehyde, benzene and other harmful substances, easily lead to excessive concentration of harmful substances. A qualified indoor air testing department can't even do an air test, so please ask experts to determine the source of pollutants immediately and let workers rework to avoid risks.
