The new house should be ventilated after renovation. How long will people live in it?

After the renovation of the new house, it is generally necessary to ventilate, and it takes at least half a year to move in. Many people have a question, how long should the new house be ventilated after renovation? There are basically three answers to this question. Some people think that one or two months is enough, others think that it takes at least three to six months, and others think that half a year is not enough. If you are not in a hurry, the longer you are free, the better.

My family has encountered this problem before, and then consulted professional environmental experts to solve this problem. Experts say that if the ventilation time is not well controlled, we will act hastily and easily lead to formaldehyde poisoning, especially now, this summer is the peak period of formaldehyde release. Today, I will use my own experience to answer your question and tell you how long it will take for your new house to be ventilated after renovation.

First of all, we must clarify the role of ventilation. Many people think that ventilation makes the odor disappear, as long as there is no odor at home, it is all wet. After renovation, harmful substances such as benzene, xylene, TVOC and formaldehyde will be produced. Except for formaldehyde, which is colorless and tasteless, most of them will give off a pungent smell, but it will evaporate quickly, and there will be no smell after 3 to 6 months of ventilation, but this does not mean that the room is safe.

Because the release cycle of formaldehyde is very long, it can last for three to fifteen years. Ventilation can't be completely removed, let alone a few months, so it is very dangerous to ventilate for a month or two, at least for more than half a year. If you are not in a hurry, it is good to stay long, but ventilation is only a palliative. Windows cannot be opened in winter, so the removal effect of formaldehyde is very poor. In a word, we must use some methods to control pollution for a long time.
