After the house is renovated, how long does it take to ventilate it before it can be moved in?

After the house is renovated, it takes at least half a year to ventilate before it can be rented, mainly because after the renovation, there will be some harmful gases in the house, such as formaldehyde and acetaldehyde. These gases need to be released for a long time to reduce their concentration in the room, and if the concentration does not go down, the human body may inhale these gases and cause some pathologies in our body. For example, uremia and leukemia that we often see are related to these gases.

First, how long is ventilation?

In fact, the ventilation time is related to the temperature and the number of ventilation times. Some people think that just buy furniture after renovation and open the windows to ventilate, but this is not the case, and during the day, you need to open the windows. At this time, the temperature rises, formaldehyde is more likely to volatilize, and then let the wind take it away, but you still need to close the windows at night.

Under normal circumstances, the ventilation time is at least half a year, which is also an accelerator for formaldehyde volatilization. <>

Second, when to choose to decorate?

If you are careful, you can find that the vast majority of people will choose to decorate in the spring, because the home decoration can be completed in 3 or 4 months, and you can buy furniture after completing the decoration, and then in the summer, when the temperature is relatively high, the home can open the windows for ventilation. Because the temperature difference between day and night is not large, there is no need to open the window every day for ventilation, so that the rate of formaldehyde release is relatively fast. <>

Thirdly, what kind of furniture should you choose?

When choosing furniture, it's best to do what you can, but don't choose furniture that uses the most glue. Because the formaldehyde in our air is actually released by synthetic glue, it is best to avoid choosing some glued materials when choosing materials. However, if you choose pure solid wood materials or other materials**, it is more expensive, so you should choose according to your budget.

Ventilation can only be moved in for half a year, because the formaldehyde content of the house is very high, and this is not conducive to the safety of our lives, and it is not conducive to our health, so we must ventilate the house.

Ventilation for a month, or about three months, so that you can move in, you can remove the odor in the room, so as to avoid formaldehyde poisoning.

It takes about a year and a half to move in, don't move in too early, otherwise it is likely to be formaldehyde poisoning.

At least half a year. Because this can remove formaldehyde well, and can also avoid formaldehyde affecting human health.

In fact, how long does it take to move in and live, and it should be treated on a case-by-case basis, and cannot be generalized. If you are worried about indoor air quality, you can find a department to conduct an air test before moving in.

At present, after many owners have renovated, they generally move in after two or three months of ventilation, while those owners who are not in a hurry to move in can be ventilated for half a year, or even longer. In fact, in the eyes of air inspection and management professionals, even ventilation for a year is not too long. The main harmful substances in newly renovated houses are formaldehyde, benzene and other volatile organic compounds.

Formaldehyde mainly comes from man-made panels and glue, and benzene mainly comes from paint. The formaldehyde release cycle is very long, reaching several years, so the plates, including finished furniture, and paint are the focus of environmental protection in the decoration process.

Many owners think that the furniture they buy is a high environmental protection grade, the floor is a national inspection-free product, and the paint is a high environmental protection index, thinking that the whole house will be free of pollution, but in fact it is not. Even if the materials used are environmentally friendly, you can't move in immediately, because you should also pay attention to the superposition effect of harmful substances, the trace harmful substances in the furniture, plus the trace harmful substances in latex paint, plus the trace harmful substances on the board and floor, it will become a large number of harmful substances.

After moving into a new home, many owners think that it is okay to buy some green plants to absorb harmful gases in the room, but in fact, plants have a shortage of plants. The adsorption function of each plant is the same as that of air conditioning and refrigeration, which is related to small, and it will naturally not be able to play a role beyond its capacity. Therefore, don't expect a few plants to absorb all the harmful gases in the new house space, if you want to kill viruses, you have to know the adsorption effective area of each plant.

The limitations of bamboo charcoal are also similar to those of plants, and they will be saturated when adsorbed to a certain extent, so they need to be exposed to the sun regularly. In the final analysis, these are just ways to treat the symptoms rather than the root cause.

Therefore, it is better to ventilate the new house and move in, depending on the materials used in the renovation of your home, your indoor area, and the method you usually take to control the air. Different pollution requires different treatment methods, so it cannot be generalized. If there is still a peculiar smell in the room after being vacant and ventilated for a long time, or the plants are yellow and wilted, you cannot rely on simple treatment methods such as activated carbon adsorption and spraying air fresheners, and you should find a professional institution for testing and treatment before moving in.

Hope it helps

Can you move in to the newly renovated house for a long time after ventilating the house?

Formaldehyde du due to decoration BAI pollution

Benzene and TVOC are volatiles, which are not only related to the installation of DAO repair materials, but also related to the temperature, which is high and volatile. In this sense, if there is little pollution, it can be solved by ventilating the house, and the ventilation time should be selected in summer, and in winter it will be white and ventilated. Too much information says that the formaldehyde volatilization time is 3-15 years, not to mention the pollutants benzene, TVOC, and radon, so ventilation for a few months or even 1 year does not necessarily mean that there is no decoration pollution.

There are more than a dozen kinds of indoor pollutants, and all of them should not exceed the standard to really not exceed the standard.

The reliable method is to install a distributed whole-house fresh air system to continuously replace the indoor air with clean outdoor air (filtered) to ensure the overall good indoor air quality in the long run!

The newly renovated house cannot be moved in immediately, because many of the materials we decorate contain harmful gases, so how long does it take for the newly renovated house to move in?

If the ventilation conditions are good, it will take at least 6-12 months.

The premise is that the ventilation conditions are good, and the furniture and building materials are also more environmentally friendly.

Why so.

Can I stay for a long time? Because the indoor air pollution of newly renovated houses is very harmful to the human body, especially families with pregnant women, children, and the elderly should pay special attention to it, and should prevent the harm caused by decoration pollution as soon as possible. You can put more pothos and onions in the room, which can absorb formaldehyde.

Four netizens have a lot of knowledge about the decoration and decoration of the new house, and they can usually go to see it.

DU check-in; New house zhi

After renovation, it is safe to ventilate and vacate for 3-6 months to move back.

Answer. According to China's housing air standard, the maximum allowable concentration of formaldehyde is (0 08mg m3).

Because there is a formaldehyde smell after the decoration of the new house, which is harmful to health, the new house needs to be ventilated for 3-6 months after the decoration is completed.

If you move in as soon as possible, there are a few other things you can do to manage it:

1. Physical removal of formaldehyde: activated carbon is a kind of physical adsorption, like activated carbon, nano live ore, bamboo charcoal, which is very safe and harmless to the human body.

2. Plant removal method: select and place plants according to the different functions and size of the room. Like aloe vera, spider plant, pothos, tiger pill orchid, one-leaf orchid, ivy and these. (Aloe vera is a very good hand at deodorizing new houses).

3. Clean water absorption method: When the new house is deodorized, put a few basins of water in the new house, and put vinegar, green onions, orange peels, etc. in the water, which can not only absorb the residual odor in the room, but also protect the paint surface of the wall after water evaporation. The water absorption method for deodorization of new houses is not only simple, convenient and economical, but the water needs to be changed twice a day.

This way the adults can stay in 40-50 days. (Except for infants and pregnant women, it takes 80-90 days).

The renovated house should be ventilated for about 3 months before it can be moved in. And when you move in, you should conduct a formaldehyde test to ensure that there is no formaldehyde before moving in. In addition, some green plants can be placed indoors, such as spider plants, pothos, etc., which can accelerate the removal of formaldehyde and enable indoor harmful gases to volatilize quickly.

How long can you move in the decoration, this is also related to the weather, the air humidity in spring and summer is high, and the airflow is slow, so the new house is decorated for a longer time. The ventilation conditions in autumn and winter are better, and the drying time is relatively short, basically about two to three months can be occupied. If there are pregnant women at home, then it is better to leave the house dry for more than half a year, which will be more safe.

Decoration removal method of formaldehyde

1. Keep ventilation: keep indoor air circulation, because the air can bring odor and formaldehyde out of the outdoors, and reduce the content of formaldehyde and odor in indoor air.

2. Activated carbon adsorption: Activated carbon has a good air purification effect, and it has a good adsorption effect. As long as the air is used as a medium, the harmful substances in the air are adsorbed, and the ammonia, formaldehyde, and benzene in the room are effectively removed, and the activated carbon is non-toxic and non-effective.

3. Plant purification: plant removal is suitable for mild pollution, and plants can be selected according to the function and area of the room. In particular, aloe vera, spider plant, tiger tail orchid, etc. have a good effect of removing formaldehyde and purifying the environment.

The new house has just been renovated and needs to be ventilated for at least 6 months.

The new house is renovated, including all furniture, and can only be moved in after ventilation for at least 6 months, and formaldehyde testing must be carried out before moving in. If there are pregnant women and children in the house, it is best to ventilate them for more than one year, because pregnant women and children are in the special period of development, and inhaling a large number of harmful gases will cause harm to the body and even suffer from respiratory diseases.

The method of removing formaldehyde in a new house is as follows:

1.The most effective way to remove formaldehyde is to open the window for ventilation, so that the flowing air can bring out the harmful gases in the new house and leave fresh air. When you open the window for ventilation, you can also open the cabinet doors at home, which can speed up the removal of formaldehyde.

2.You can put some green plants that purify the air in the new house to accelerate the absorption of formaldehyde, such as pothos, ivy, etc., which can effectively absorb harmful gases in the new house.

3.You can also use physical methods to adsorb harmful gases in the new house, the adsorption capacity of activated carbon is very strong, and it is cheap, the effect of adsorbing formaldehyde is very good, pay attention to the use of activated carbon for a period of time needs to be replaced with a new one.

Summary: After the house is renovated, it is best to ventilate for more than half a year before moving in, especially for newlyweds who plan to have children, families with pregnant women and children at home should be renovated and ventilated for more than a year before moving in, all belong to a special period, physical health can not be sloppy, inhalation of a large number of harmful gases will cause irreversible damage to the body.
