Formaldehyde removal method for new houses, methods for removing formaldehyde in new houses

Method 1: Open the window for ventilation.

Ventilation can quickly reduce the formaldehyde concentration in the home in a short period of time, and at the same time can take away the pungent odor in the house, and the effect is immediate, so you should open the windows frequently for ventilation after decoration. However, this effect is only temporary, and it will be ** when the window is closed, because the volatilization period of formaldehyde is very long, which can reach 3 15 years, and it cannot be completely solved by ventilation alone.

Method 2: Air purifier.

Although opening windows and ventilation to remove formaldehyde has a short-term effect, but the limitations are too great, so it should be used together with other methods to better control formaldehyde, such as professional formaldehyde removal air purifiers, which can not only efficiently adsorb formaldehyde, but also decompose formaldehyde into carbon dioxide and water, completely eliminate the secondary pollution of formaldehyde, and let us enjoy a fresh and healthy breathing environment.

Method 3: Aldehyde removal spray.

Aldehyde removal spray is a new type of tool specifically for formaldehyde. However, this method is to treat the symptoms but not the root cause, and the film will also be destroyed because of our daily activities, so the formaldehyde will volatilize again, so it needs to be sprayed regularly. Moreover, the aldehyde removal spray also has a certain chemical composition inside, although it is harmless to the human body, it is also recommended that you use it sparingly.

Method 1: Air purifier The volatilization period of formaldehyde is as long as 3-15 years, that is to say, the treatment of formaldehyde must be carried out in a sustainable way. In addition to formaldehyde, the air purifier has developed an adsorption + decomposition purification method for formaldehyde, which can quickly adsorb formaldehyde and decompose formaldehyde into carbon dioxide and water, so as to create a line of defense for us to control formaldehyde and continue to ensure our healthy breathing.

Method 2: Activated carbon This is also an adsorption material, its ability to adsorb formaldehyde is also OK, ** is also very economical, and it is also helpful to remove indoor pollution. However, activated charcoal will lose its effect due to saturation after a period of use.

Therefore, everyone needs to replace it with a new one every 20 days, otherwise it will be **, and the indoor formaldehyde concentration will rise again.

Method 3: Ventilation method Opening windows for ventilation is the simplest and most economical way to remove aldehydes. As long as the windows of the home are opened and the wind blows in, the indoor formaldehyde concentration will decrease, and the effect in the short term is obvious.

However, there is also a defect in opening windows for ventilation, and it is not suitable for weather such as no wind and rain. Therefore, it is recommended that you open the window for ventilation while also using it with other methods.

I have just experienced decoration, formaldehyde removal, and moved in not long ago, so let's share the way I have taken.

1. The most important thing to remove formaldehyde is ventilation. Answer: The main decoration is just at the end of May last year, coordinates Hangzhou, the weather is relatively fine, natural ventilation is the most economical and effective way, no cost, especially in the warmer (hot) season, formaldehyde is volatile (19), at this time the effect of natural ventilation is very good, note, continuous window ventilation will be better than the effect of stuffy method. (Attention!)

Be sure to wait for ten days, the paint and plates of the decoration will be ventilated after they are naturally dry, otherwise they will dry and crack! ）

2. Fan. For the wardrobes and display cabinets in the guest bedroom and living room, the respondent used two floor fans to blow air on the open cabinets and drawers to assist ventilation.

3. Activated carbon. **Relatively cheap, it is said to be able to adsorb formaldehyde, the answer is to use it to remove the smell of decoration, and it can be used in the shoe cabinet and refrigerator to remove the odor in the future, and it is also purchased and used.

4. Photophyllin. This spray is seen in the community owners, mainly for wood boards, furniture spraying, decomposition of formaldehyde after contact, the answer to the master a total of twice, are after work with the father to operate their own, the smell of the spray is very light herbaceous, more natural, no traces. Greatly good.

About a month and a half, the taste is basically gone, plus the decoration is the material I bought myself, and I am more assured of the materials, and I have not been vacant for a long time to move in, and there is no discomfort.

As long as the decoration of the new house will inevitably face formaldehyde pollution, but there has been no good way for formaldehyde pollution, and the formaldehyde release period is at least 3 years or even 15 years, during this time we must choose an effective and fast aldehyde removal method!

Formaldehyde removal method 1, open windows for ventilation is necessary.

Ventilation is a very convenient method to remove aldehyde, we only need to keep the windows open every day to ventilate, promote outdoor air circulation and replacement, can reduce the concentration of formaldehyde. Therefore, if you want to remove aldehydes quickly, ventilation must be a step. However, it is not enough to remove formaldehyde by ventilation alone.

In case of bad weather and inconvenient opening of windows, the effect will be greatly reduced, so ventilation can only be used as an auxiliary work.

Aldehyde removal method 2, decomposition of particles.

Choose a purification package that can automatically adsorb and decompose formaldehyde, benzene and TVOC and other harmful gases for decoration, and be sun-free for three years, so you don't have to worry about adsorption saturation and secondary pollution at home.

3. Regularly wipe the furniture to remove odor.

The odor emitted by benzene is also a headache for us. Furniture deodorization is a very important point. Choosing an aldehyde removal spray can effectively remove the odor and harmful substances released from the inside of the board.

4. Appropriate placement of green plants.

Plants are recognized as a method that can adsorb formaldehyde, so we can put some purified air at home to beautify the environment. It's just that the adsorption capacity of green plants is limited, and it is easy to be poisoned by high concentrations of formaldehyde, so we can only use it as an auxiliary method.

How to remove formaldehyde in a new house and what method is the most effective.

1. Ventilation. Indoor air circulation, this practice can also be easily brought out of the outdoor odor and formaldehyde by the flowing air, and can also reduce the content of formaldehyde and odor in the indoor air, and can not reduce the harm to human health. Therefore, it is recommended that you ventilate the newly renovated new house for a period of time before moving in, which can also remove formaldehyde and odor in the room.

2. Activated carbon adsorption.

Activated carbon can play a role in purifying the air, it mainly relies on air as a medium, so that it can well adsorb harmful substances in the air, can remove indoor ammonia, formaldehyde, benzene is very good, and this product is also a non-polluting, non-toxic, non-... When using, as long as two to three dishes of household activated carbon are placed in each house, generally speaking, indoor formaldehyde and odor can be well removed within 72 hours.

3. Plant purification.

In general, this plant removal method is more suitable for relatively light environmental pollution, such as the pollution value is less than 2 times the national standard. At the same time, it is also necessary to choose the plants according to the different functions of the room and the size of the room. In general, for example, for example, a room of about 10 square meters, then it is more appropriate to consider putting two pots of plants that are meters high.

For example, aloe vera, spider plant and tiger tail orchid, these plants can remove formaldehyde and play a role in purifying the indoor environment.

4. Food deodorization.

Vinegar deodorizes, which can protect the paint surface of the wall with the right amount of evaporated water, and at the same time eliminate residual odors. You can use a basin or a small bucket of water to fill it with cold water, then add some vinegar, put it in a ventilated room, and open the furniture door. If you think it's enough, you can consider buying some pineapple, knowing that pineapple can also absorb the smell of paint, and at the same time, it can also exude the fragrance of pineapple, which can also speed up the removal of odors.

The new home is well decorated, and the national standard is, if it is exceeded, it will not be moved in first. If you want to remove formaldehyde quickly, you can choose to spray Diallin + more ventilation, which is better. Then take the remediation measures:

Step 1: Open the windows for ventilation. The best way is to open the window for ventilation for a long time, and discharge the pollutants in the indoor air to the outside through air convection. It can also be assisted by an electric fan to accelerate the convection of indoor and outdoor air.

Step 2: Use activated carbon for air purification. After effective ventilation, indoor air pollution has been greatly reduced, so the focus should be shifted to solving the source of indoor pollutant release, so as to ensure continuous purification of harmful gases.

Step 3: Adopt the plant decontamination method. Indoor suitable for planting flower plants are: spider plant (including orchid grass), cactus (cactus), aloe vera, etc., this kind of plant has a certain purification effect, a little better is the Diarin plant extract, can directly decompose the roots.

Step 4: Apply Diallin Spray. This is currently better, but also more effective, the prospect is very bright a removal method, it combines the advantages of plant removal method and chemical removal method and abandons their shortcomings, first of all, it is safer than chemical removal of formaldehyde without secondary pollution, compared with plant removal method, because it is a herbal extract, so the effect is better.

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.

Don't be misled by pothos, activated charcoal, grapefruit peel, etc., **TV has done a special report experiment to refute rumors.

Indoor pollution is not only formaldehyde, but also benzene, toluene, xylene, ammonia and TVOC, but formaldehyde is more familiar because it is a class I carcinogen.

There are only two effective ways to remove decoration pollution: ventilation and professional treatment.

No matter what method is used to remove decoration pollution, the first thing to understand is the degree of pollution. Because the quality of the decoration materials used in the decoration process is uneven, even if all the decoration is made of environmentally friendly materials, it should be tested before moving in. Understand the degree of pollution in your home and then choose a reasonable removal method.

It must be said here that you must find a formal testing agency to do decoration pollution testing, the data error of the test box and handheld detector is very large, **News has also been reported, you can search on Tencent**: Is self-testing formaldehyde reliable? ）

Let's talk about ventilation first, this method is only suitable for houses that are not seriously polluted, if the multiple of the excess is too high, don't ventilate, and it may not be able to meet the living standard for two years. Although ventilation does not cost money, it is more time-consuming and laborious, and the house is vacant for a long time, so it is not recommended to use this method if you are in a hurry to move in. Moreover, it must be ventilated for a long time to have an effect, and the formaldehyde release cycle in furniture is as long as 3-15 years.

We must be prepared for a long-term battle with formaldehyde.

There is also a way is professional governance, indoor home environmental protection after many years of a catalyst, under the action of ultraviolet light can make formaldehyde, toluene, TVOC and other harmful organic substances decompose into harmless gas, so as to achieve the purpose of removing formaldehyde. It is important to remember that the photocatalyst needs to react in the presence of light, and the more light it is, the better. However, in poor lighting or shady corners, the effect of this method in removing formaldehyde becomes limited.

The third generation of formaldehyde removal technology: air catalyst.

Like a photocatalyst, it is also a catalyst, but the difference is that the reaction medium of this catalyst is air. As long as it is in contact with the air, it can decompose harmful pollutants such as formaldehyde, benzene, toluene, xylene, ammonia, and TVOC. This solves some of the limitations of photocatalysts, and it can be said that the effect of governance is more thorough.

Moreover, the air catalyst agent will form a protective film on the surface of the furniture, which can prevent the continuous release of formaldehyde in the deep layers of the furniture.

After the decoration of the new house, the release of formaldehyde will be relatively large, which has a certain danger to human health. Here are some effective ways to remove formaldehyde:

Ventilation method: through the flow of air, the harmful gases are discharged to the outside, which is a simple and effective method. However, the formaldehyde release cycle is long, generally three to fifteen years, so the ventilation method alone cannot meet the requirements.

Activated carbon: low cost, green and safe, but limited function, belongs to the passive removal of formaldehyde method, the purification area is relatively small, and a large amount of activity is required to play a good effect.

Plants and fruits: green and safe, beautify the environment, the effect is limited, similar to activated carbon, the purification area is relatively small, and it is also a matter of quantity.

Photocatalyst method: the use of photocatalyst materials to adsorb and decompose harmful substances such as formaldehyde. This method can quickly and effectively remove nucleated collapsing formaldehyde.

Air purifier: When choosing a formaldehyde removal air purifier, you must choose a professional air purifier that can decompose formaldehyde, otherwise it is very easy to cause secondary pollution
