装修房子一般要3个月能够装好，常规情况下应该3个月以后才能入住。房子入住时间应该以房间甲醛浓度为标准，房间甲醛浓度安全标准是0.1mg/m3，超过这个浓度就可能会甲醛中毒。新装修房间一般情况下甲醛浓度都会超标，有的甚至会超标4--6倍以上。开窗通风是很好的方法！ 关门关窗容易引起甲醛中毒。
Decoration of the house generally takes three months to be installed, under normal circumstances should be three months before admission. The occupancy time of a house should be based on the concentration of formaldehyde in the room. The safety standard for the concentration of formaldehyde in the room is 0.1mg/m3. If the concentration exceeds this level, formaldehyde poisoning may occur. In general, the formaldehyde concentration in newly decorated rooms will exceed the standard, and some even exceed the standard by 4-6 times. Opening windows and ventilating is a good way! Closing doors and windows can easily cause formaldehyde poisoning.
