To put it simply, the ventilation efficiency is the highest when convection is formed in the room (windows are open on both sides). However, when it is cold or in winter, when you need to ventilate indoors (such as kitchen smoke exhaust), close the window and turn on the exhaust fan, so that the indoor air renewal efficiency is the highest. If you want to be more serious, you need to list the aerodynamic formulas.

The first thing to do after the decoration is completed is to detect formaldehyde, if the formaldehyde is not exceeded after the test is completed, it may not be a problem with high formaldehyde concentration, you can test it one by one, first look at the wall, floor, if not, see if it is the smell of the wardrobe.
It is recommended that you move in after half a year, you can put some bamboo charcoal, onions, etc. to remove odors, formaldehyde and other harmful substances, and ventilate frequently.
