Does an old house have formaldehyde? What should I do if there is formaldehyde in my new house?

Old houses generally do not have them, and if you buy new furniture or renovate them, there must be formaldehyde.

1. After the decoration, the house will have the presence of formaldehyde and other harmful substances, and whether there is a peculiar smell is not the basis for judging whether it contains toxic gases and substances. Generally, a renovated house can only be inhabited after a month of ventilation.

2. Planting the following plant bonsai indoors can effectively remove toxic and harmful gases and substances:

Vitrium is most effective at removing formaldehyde and benzene;

Aster, cockscomb and other types of plants, can absorb a large amount of uranium and other radionuclides;

Aloe vera, spider plant and tiger tail plant remove formaldehyde;

Ivy, Yueji, rose, aloe vera and evergreen can effectively remove indoor trichloroethylene, sulfur hydrogen, benzene, phenol, hydrogen fluoride and ether, etc.;

Saxivia orchid, monstera and one-leaf orchid can absorb more than 80% of the harmful gases in the room;

Asparagus can remove heavy metal particles;

Citrus, rosemary and spider plants, for example, can greatly reduce the number of bacteria and microorganisms in indoor air.

Spider plants are also effective at absorbing carbon dioxide;

Some succulent flowers of the cactus family rarely emit carbon dioxide at night;

Wisteria is highly resistant to sulfur dioxide, chlorine and hydrogen fluoride, as well as chromium, and some leafy and water-loving plants such as pothos can keep indoor air humidity at an excellent state.

No, it's not just being renovated.

There is formaldehyde in the room, what does it smell like for you.

If the human body is exposed to formaldehyde for a long time, it will cause chronic respiratory diseases, and there will be a risk of cancer.

1.Open all doors and windows to promote air circulation, so that harmful gases can be discharged to the outside through the flow of air, which is simple and effective. However, this method should be used to maintain ventilation for a long time, and a large fan can also be used to enhance the wind and assist in ventilation.

In this cycle, forced ventilation for a month, the odor in the room will be greatly reduced. For some movable furniture, try to place vents so that odors can be discharged directly to the outside.

4.Plants such as green plants, aloe vera, cacti, pothos and other plants have a certain absorption capacity for formaldehyde, and can slowly consume the surrounding formaldehyde through photosynthesis. Because it is a plant, it is very safe and does not produce other harmful effects.

However, it should be noted that the absorption of formaldehyde by plants is limited and can only be used as one of the comprehensive treatment methods to remove formaldehyde.

5.Ventilation is an indispensable method of removing formaldehyde indoors, but when the outdoor wind is not strong enough, it is necessary to strengthen ventilation. At this time, you can buy a high-power industrial fan to assist in the removal of harmful gases in the house, which can accelerate the circulation of air inside and outside the house, which is of great help to remove indoor decoration pollution.

The formaldehyde problem in the old house still exists, the formaldehyde volatilization period is 3-15 years, and the volatilization temperature is 19 degrees.

It has almost become a consensus that we will not move in immediately after the renovation of the new house, but will leave the house vacant for a while. Because this can reduce the decoration pollution in the indoor air, especially formaldehyde, it will also be discharged outdoors while the indoor and outdoor air is replaced. So how long does it take to sit vacant and dry before you can move into a new house?

Whether we can move in or not, we have to see whether the indoor formaldehyde concentration is up to standard. Under normal circumstances, the formaldehyde release of furniture or various home decoration materials will reach a peak within 3-5 months after opening the package, and it will enter a slow and small amount of release after half a year. This also means that the new house must be vacant for at least half a year, and only after passing the test can it be occupied!

So why does the house that has been renovated for many years still have the phenomenon of excessive formaldehyde? This is because the volatilization cycle of formaldehyde is as long as 3-15 years, even if it is an old house, decoration materials and even furniture are still releasing formaldehyde, and formaldehyde is a harmful gas that is easy to superimpose, and it will reach the range of exceeding the standard if you are not careful. This is also the fundamental reason why the use of environmentally friendly materials for decoration, or the purchase of environmentally friendly furniture, will still occur excessive formaldehyde.

This may seem incredible, but it's easy to understand. We are buying every single product product that meets the national standards and can be called environmentally friendly products, but these products will more or less contain a certain amount of formaldehyde, which means that wallpaper, wooden doors, floors, paints, coatings contain a certain amount of formaldehyde.

In addition, another reason for the formaldehyde excess in the old house is the entry of new pollution sources, in our long life, it is bound to add some new objects, then it is bound to be a new formaldehyde release source, and because formaldehyde can not be seen and touched, we can not deal with it correctly, which will cause one after another formaldehyde exceeding the standard caused by poisoning incidents!

So how do we properly dispose of formaldehyde? The German Seiko Neusenberg air purifier has developed a purification method of adsorption + decomposition for formaldehyde, which can not only quickly adsorb formaldehyde, but also decompose formaldehyde into carbon dioxide and water, eliminate the secondary pollution of formaldehyde, and continue to protect our respiratory health.

Generally speaking, the old house does not have formaldehyde, unless the old house has been renovated, then there is a possibility of formaldehyde on these decoration materials.

Does the house have formaldehyde? The old house is free of formaldehyde, because of formaldehyde, he will not stay in the house for a long time, generally speaking, your newly renovated house, his formaldehyde materials are still available, but if your house is more than two years, he will not have formaldehyde.

There is formaldehyde in the general room, but there is very little formaldehyde in the old house, which can be ignored. The more new furniture. The more formaldehyde you pay, the more formaldehyde you have. Over time, the content will slowly decrease. But it's hard to disappear.

Old houses are normally formaldehyde-free. After all, it's been so long. Formaldehyde has almost disappeared.

The old house can't be said to have no formaldehyde, but the formaldehyde content is very low.

Does an old house have formaldehyde? Old houses generally do not have formaldehyde, and houses that are more than ten years old have no formaldehyde.

It depends on what materials are used in the decoration of the old house, and how old it is. Generally speaking, formaldehyde is emitted chronically, and some materials are difficult to use for decades. However, if it does not exceed a certain concentration, the effect is not great. If you are worried, it is recommended to get tested.

Old houses are generally free of formaldehyde, but if there are new furniture in the old house, this is not certain.

Look at the formaldehyde content of the house will be very low, will not affect the health of the body, if the decoration will be formaldehyde.

In the case of high indoor temperature, formaldehyde volatilizes faster. The most likely place to appear formaldehyde indoors is wooden board furniture or flooring, among which the use of man-made panels is the most terrible, especially some adhesives hidden in his depths, the incubation period of formaldehyde can reach 15 years!

It should be said that there are almost none. Formaldehyde is naturally occurring in wood.

I think the formaldehyde in the old house will exceed the standard, and I think there will be formaldehyde after the house is renovated.

Old houses generally do not cause formaldehyde to exceed the standard. It is likely that there will be formaldehyde after the house is renovated, because there will be some formaldehyde if it is newly renovated.

It will not exceed the standard, if some items containing formaldehyde are used, then formaldehyde will appear, which will cause harm to the body.

For the newly renovated new house, it will not be moved in immediately, mainly because of the problem of formaldehyde pollution in decoration, because the formaldehyde content will have a great impact on human health, so people will often control formaldehyde within a safety standard through some effective methods after decoration, and will move in, so what are the hazards of formaldehyde in the new house? Let's take a look.

1. What are the hazards of formaldehyde in a new house?

Formaldehyde in the new house has dizziness, vomiting, suffocation, nausea, allergies, poor breathing, frequent coughing, sneezing, fetal malformations, leukemia and other hazards, when moving into a new home, there are symptoms such as dizziness, vomiting, suffocation, nausea and other symptoms on behalf of formaldehyde poisoning, if you live for a long time, the consequences are more serious, which will lead to decreased immunity, frequent colds, and may also get cancer.

Second, how to solve the formaldehyde problem of the new house.

1. Open windows for ventilation.

Now most of the new house decoration is made of environmentally friendly materials, but there are more decoration materials, formaldehyde content will also be excessive, and the volatilization time of formaldehyde is as long as 15 years, so it is necessary to prepare for long-term treatment, and open windows and ventilation This solution to formaldehyde is a very good choice, in daily home life, you can maintain 3-5 hours of ventilation time every day, which is very time-saving and labor-saving.

2. Plant purification.

Now most of the home will raise some plants, not only to beautify the home environment, but also to purify the indoor air, because there are many plants in nature have the effect of removing formaldehyde, especially spider plant, aloe vera and other plants, can be said to be the nemesis of formaldehyde, can purify more than 95% of formaldehyde, and can be planted into potted plants, very small, placed in the formaldehyde source cabinet will not have an impact.
