How to remove formaldehyde in a new house, how to remove formaldehyde in a new house

How to remove formaldehyde in new houses, has always been a problem that bothers everyone, there are too many false information on the market, and it makes people choose one head and two big, I don't know which one is true and which one is fake, and the following is an introduction to several commonly used small methods to remove aldehyde for you to choose.

1. Wise Stone.

It is currently a relatively cost-effective formaldehyde removal product, its advantage is that it can be decomposed into water and carbon dioxide at the same time of absorbing formaldehyde and harmless substances to the human body, because of its decomposition characteristics, so that it will not appear adsorption saturation and indoor secondary pollution, and suitable for various types of environmental use. In addition, its removal rate is also dozens of times that of traditional adsorbent materials. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle

2. Activated carbon.

Activated carbon has a large number of irregular pores, in which the pores similar to formaldehyde molecules will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, when the adsorption is saturated, it may cause secondary pollution, and it must be replaced regularly when used.

3. Open windows for ventilation.

Open the window ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air will dilute the indoor air containing formaldehyde to achieve the purpose of purifying formaldehyde, but the window is easily affected by the weather, and the effect is also affected by the house type when used.

Fourth, high temperature.

The release rate of formaldehyde mainly depends on two factors, one is temperature, the other is humidity, so we can use this characteristic of formaldehyde, use heaters, humidifiers, etc. to keep the room in a state of high temperature and high humidity, and then we can cooperate with ventilation or adsorption materials to absorb the formaldehyde that has been released at home, this method is mainly to treat the latent formaldehyde in the home, and the effect is very good.

5. Formaldehyde remover.

Formaldehyde scavenger is the use of chemical or biological principles, formaldehyde decomposition into harmless carbon dioxide and water or other harmless substances, so as to achieve the purpose of purifying formaldehyde, but there are many manufacturers, the quality is also uneven, you must keep your eyes open when buying, otherwise it is easy to cause the introduction of other harmful substances.

In general, no method is absolutely perfect, and the effect will only be better if multiple methods are used together.

1. Open window ventilation: window ventilation is the simplest and most direct way to remove formaldehyde, but removing formaldehyde is a long-term work, and the effect of window ventilation is slow, so it can only be used as an auxiliary method.

2. Activated carbon adsorption: Activated carbon is cheap, simple and practical, and harmless to the human body. There are many small pores and crevices, relying on this physical adsorption of formaldehyde method has a certain effect, but after 1 month the activated carbon is saturated, the adsorption effect will disappear, and the activated carbon will emit a part of the harmful gas that has been adsorbed after the adsorption saturation, which needs to be replaced regularly.

3. Green plant purification: spider plant, tiger tail orchid, pothos and other plants can purify the air through photosynthesis, and also purify some formaldehyde gas. However, the adsorption capacity of plants is limited, and photosynthesis has no effect at night.

4. Air purifier: The air purifier can remove a certain amount of formaldehyde within a certain period of time, but formaldehyde exists in decoration materials and is continuously released, so this method treats the symptoms but not the root cause.

5. Install MIA fresh air system: the fresh air system sends the outdoor fresh air to the room through the fresh air supply device after filtering it through the fresh fan, the outside air has high oxygen content, but there are also many harmful gases and germs, and the filtration system of the fresh air fan can effectively intercept these harmful gases, which not only ensures that the indoor oxygen is sufficient, but also ensures the cleanliness and safety of the indoor air.

There are many ways to remove formaldehyde from a new house, and here are some common ones:

Ventilation method: Through the flow of air, harmful gases are discharged to the outside, which is a simple and effective method. However, the release cycle of nuclear aldehyde is long, generally three to fifteen years, and it is obviously unrealistic to idle the new house for more than three years after decoration.

Therefore, ventilation alone is not enough.

Activated carbon adsorbents: Activated carbon is a relatively inexpensive and practical method of removing formaldehyde, and it is also the most widely used. It is characterized by strong adsorption capacity and is not easy to cause secondary pollution.

Solid activated carbon has the characteristics of many pores, and has a good adsorption and decomposition effect on harmful substances such as formaldehyde. In general, the smaller the particles of activated carbon, the better the adsorption effect. But activated charcoal needs to be replaced regularly.

Greenery can remove odors and formaldehyde.

There are four ways to remove formaldehyde in new houses: 1. Open windows for ventilation frequently; 2. Place plants, activated carbon and other items indoors to purify indoor air; 3. Use edible vinegar fumigation, nano photocatalysis, spraying disinfectants and other methods to reduce indoor formaldehyde concentration; 4. The use of air purifiers to adsorb indoor formaldehyde and other decoration pollutants can also effectively improve indoor air quality.

After the house is renovated, it is inevitable that there will be polluting substances left indoors, formaldehyde is the most concerned pollutant in decoration pollution, it is present in some adhesives, and the harm to the human body is very great. So, let's take you to understand how to remove formaldehyde in a new house.

1. Ventilation removes formaldehyde from the new house.

After the decoration of the new house, it is necessary to open the doors and windows frequently for ventilation, and I believe most people know that they will do it, because this can discharge harmful substances indoors to reduce indoor pollution. You can place several electric fans in the living room and turn them on to increase the speed of indoor air flow, which is a very simple and effective way to remove formaldehyde, but it should be used for a long time, so as to achieve the effect. For newly renovated houses, the pollution degree is also relatively high, no matter what deodorant is used, the effect is not very good, and the only way is to open the doors and windows to allow the air to circulate.

2. Formaldehyde removal method for green plants.

Many green plants are also very effective in removing formaldehyde, because they all have a certain adsorption capacity, they can effectively absorb some harmful gases in the room. Therefore, after the renovation of a new house, many people will place more green plants indoors, which can be viewed on the one hand, and formaldehyde can be removed on the other hand. But its adsorption is limited, so it alone is certainly not enough to remove formaldehyde.

3. Use an air purifier to remove formaldehyde.

Many people also place an air purifier in their new home to remove harmful substances left behind by the renovation. However, there are many styles and types of air purifiers on the market, and the effect of each style is different, so you should look at the specific situation of the manufacturer when buying, and choose it in combination with your actual situation.

There are several ways to remove formaldehyde in a new house:

1.Ventilation: Replace the air in the room regularly, open windows to let fresh air in, and expel pollutants from the outside. During specific periods such as after renovation and after moving into a new home, open more windows for ventilation to ensure air circulation.

2.Plant purification: Some plants have a certain air purification effect, such as aloe vera, spider plant, tiger tail orchid, etc., which can be placed indoors to remove formaldehyde.

However, it should be noted that the effect of plant purification is slower and needs to grow and function over a longer period of time. Hall matching.

3.Activated carbon adsorption: Activated carbon is a more commonly used air purifier, which can adsorb harmful substances such as formaldehyde in the room and reduce the concentration of indoor pollution. Activated charcoal can be placed in the room or used in an air purifier to achieve the effect of adsorbing formaldehyde.

4.Photocatalyst technology: Photocatalysts can use light-catalyzed reactions to remove pollutants from the air, including formaldehyde. Installing equipment such as photocatalyst air purifiers indoors can effectively remove indoor formaldehyde.

5.Formaldehyde detection and treatment: You can purchase formaldehyde detection instruments to regularly detect indoor formaldehyde concentration. If the formaldehyde concentration is too high, corresponding treatment measures can be taken, such as redecorating, replacing furniture, using detergents, etc.

It should be noted that the above methods can reduce the indoor formaldehyde concentration, but the complete removal of formaldehyde requires the use of materials with low formaldehyde emission as much as possible during decoration and follow scientific construction specifications.

1. The principle of removing formaldehyde, adsorbing pollution odors, but can not be decomposed, can be adsorbed, but very small, a drop in the bucket, for the whole space, basically no dispersion has an effect. Moreover, after adsorption saturation, it itself becomes a source of pollution.

2. Absorb lead from air pollution, and decompose a small amount in the body, although effective, but very small, a drop in the water, for the whole space, a few potted plants basically have no effect. Moreover, plants have low absorption values, i.e. when the concentration of pollutants is reduced to a certain value, plants will not absorb again.

3. Methods such as peel to remove formaldehyde only cover up the odor, and there is no effect of removing formaldehyde at all.

4. Diarin extracted from plants can just meet the desire of plants to remove formaldehyde, and can remove formaldehyde well.

1. Open windows for ventilation.

Open the doors and windows for ventilation, this is one thing that many owners will do after decorating the house, this method is relatively simple, and it is also very economical and does not cost money, but we should pay attention to the fact that when opening the doors and windows, the doors and drawers of the cabinet should also be opened, which is conducive to the release of formaldehyde, but it should be noted that the ventilation effect is good for the convection ventilation, and the windows should be closed when it rains in summer to avoid wetting the new home.

2. Place activated carbon.

Some people may not have heard of this method, we can go directly to the store to buy some activated carbon or online shopping, it is not expensive, and then put them in the new house, so that it can play a role in absorbing formaldehyde and reducing indoor formaldehyde content. Although some of the formaldehyde can be emitted through long-term ventilation, the effect of activated carbon is more obvious for hidden places.

3. Plant potted plants.

This method is also more practical, not only to dispel odors in the air, eliminate these harmful substances, but also to bring freshness to our new home, but also to play a role in decorating the home. Therefore, it is recommended to buy some plants that remove formaldehyde, such as spider plant, tiger tail and aloe vera, both before and after moving in.

These plants are not only easy to grow and care for, but also can effectively remove formaldehyde, making them a good choice for beautifying the home environment.

4. Black tea to remove formaldehyde.

Not many people know about this method, but it can have the effect of purifying the air. We can take 300 grams of black tea, put them in a basin, and then use boiling water to make black tea. Then put the black tea pot in the room, and open the window for ventilation, for a week, can basically remove formaldehyde and odor.

There are 4 ways to remove formaldehyde in a new house:

Method 1: Activated carbon.

There are fine pores inside the activated carbon, which can play the role of adsorbing formaldehyde, but its adsorption capacity is certain, once the adsorption saturation will lose the adsorption effect, and the temperature may rise and there may be a problem of re-release, so the use of activated carbon must be replaced regularly once a month to avoid secondary pollution.

Method 2: Physical decomposition.

Baizao Na is a purification material that environmental protection engineers have been more respected in recent years, its adsorption and purification speed will be faster than that of activated carbon, and the addition of decomposition components can automatically adsorb and decompose harmful gases, without worrying about adsorption saturation, and it is sun-free, which is more suitable for people who are in a hurry to live or are too lazy to dry.

Method 3: Decompose the medium.

Natural decomposition medium is a safe and non-toxic mineral purification, harmless to the human body and does not hurt furniture, after spraying, it can penetrate the inside of the furniture board to induce the decomposition of formaldehyde, which has a great role in promoting the removal of internal pollution and furniture odor of furniture, and can be purified from the source to prevent formaldehyde from being re-improved in the later stage.

Method 4, green plant method.

In the room where aldehyde removal is needed, we can put a few pots of green plants appropriately, and by virtue of their photosynthesis and some microbial actions in their roots, we can metabolize formaldehyde accordingly, thereby reducing the formaldehyde concentration in the room. However, the adsorption effect of plants is limited, and it can be used as an auxiliary method.

Under normal circumstances, it is recommended to ventilate for more than one year after the new house is renovated, so that it is more secure. For friends who are nervous about check-in time, it is okay to check in as soon as possible by doing the following points.

Clause. 1. Ventilation. Regardless of the length of stay, it is necessary to ensure frequent ventilation, ventilation is the most important way to remove aldehyde, and it is best to meet high temperature and high humidity (the property of formaldehyde is soluble in water, and the boiling point is 19).

Clause. 1. Ye Guang mud and activated carbon. Activated carbon is the deodorant and aldehyde removal product that we are more familiar with, it mainly adsorbs formaldehyde, so it is also easy to be saturated, and it will be released again if it is not replaced in time. Ye Guangni has made an upgrade, after adsorbing formaldehyde, it can decompose formaldehyde, so it is not easy to saturate, and it is very convenient to put it in the cabinet at home.

Clause. Second, aldehyde removal spray. There are many weight-removing sprays on the market, and the one that the respondent is willing to recommend is a photophyllin, which is relatively safe. It contains plant extracts, so it does not need ultraviolet catalysis to decompose formaldehyde, which is suitable for new houses with poor lighting conditions.

Clause. 3. Fresh air device. This is a recent development, which can replace indoor and outdoor air and ensure indoor air quality. However, the fresh air device needs to be installed before the decoration, and many friends may be too late.

Clause. Fourth, green plants. Experiments have shown that it has the effect of absorbing formaldehyde, but experiments have also shown that its effect of removing aldehyde is very small, and a large number of green plants are needed, and it is unrealistic to rely on green plants to remove aldehyde, but it can be placed at home to beautify the environment.
