Can formaldehyde testing be used to house people?

I got it wrong, it should be 0.2 to 0.3, and the standard is 0.1, so it’s best not to live now. It also depends on the situation of your home. After all, the doors and windows were all closed during the test. If you maintain ventilation, you can reduce the adverse effects. The specific methods are as follows:

First, ventilation management. When the temperature is higher than 30 degrees, try to maintain indoor ventilation. In spring and autumn, the house should be kept ventilated throughout the day as much as possible. If ventilation is not possible throughout the day, the whole house must be ventilated when you get up in the morning, when you return home from going out, and before going to bed at night. When ventilating, especially when the wind is relatively strong, try to open the cabinet doors and drawers. When the doors and windows are closed and the room is not ventilated, especially when sleeping at night, cupboard doors and drawers should be closed.

The second is adsorption. Buy diatom mud or pure diatom, buy the quantity according to the instruction manual, put it in the cupboard, take it out for a few months to let it air out, and then put it back. This one can also absorb formaldehyde.
