How to remove harmful substances such as formaldehyde indoors

Removing formaldehyde is a major problem after many home decorations, and everyone will search on the Internet to see what good methods can be used for reference, but there are many unscientific methods to remove formaldehyde, which not only delays the time of check-in, but also increases the difficulty of removing formaldehyde.

1. Wise Stone.

It is a very popular purification product on the market in recent years, the main reason is that it has the dual function of absorption and decomposition, can actively absorb free formaldehyde in the air, and does not have to worry about the influence of external factors such as temperature, humidity, light, etc. The adsorbed formaldehyde will also be decomposed into water and carbon dioxide and discharged from the body, without drying and no secondary pollution. 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.

Using activated charcoal is also a great option. The surface of activated carbon is rich in pores, which can adsorb indoor odors, and also has a certain effect on pollution control, but the activated carbon treatment capacity is limited, and it will produce saturation after about half a month of use, and it is impossible to continue to work

3. Open windows for ventilation.

Open window ventilation is a very simple method to remove aldehyde, the purification principle is indoor and outdoor air circulation replacement, can release free formaldehyde and other harmful gases in the indoor air to the outdoors, reduce the indoor formaldehyde concentration. The efficiency of its aldehyde removal is directly related to the size of the outdoor wind, and the greater the outdoor wind, the higher the purification efficiency.

Fourth, high temperature drying.

High temperature and drying can accelerate the volatilization of formaldehyde and other harmful substances, so you can take out drawers, movable furniture, mattresses, etc., to the balcony for ventilation and drying, and furniture that can not be dried can be fumigated at high temperature, with garment steamer, steam engine mop, high temperature steam to speed up the volatilization of formaldehyde.

5. Formaldehyde remover.

There are many principles of formaldehyde scavengers, there are formaldehyde decomposition, formaldehyde is closed, the former is only the free formaldehyde is decomposed, the bonded formaldehyde inside the material is still in the continuous decomposition and release, the latter is the use of protective film to isolate formaldehyde from the air, formaldehyde still exists, when the protective film is broken, formaldehyde will still gush out in large quantities!

Finally, I would like to remind everyone: no matter what method is used to solve the problem of decoration pollution, we must first detect the indoor decoration pollution, and adopt different solutions for different degrees of pollution, and the effect will be twice the result with half the effort.

1. Strengthen ventilation. This is an ordinary method. However, formaldehyde, benzene and other harmful substances are hidden in the depths of furniture and wall materials, and the release period is 3-15 years, which cannot be removed in a short period of time.

2. Use a purifier. This is the approach adopted by consumers whose families are more affluent. However, there are many kinds of purifiers on the market, most of which are vain, and the quality and price are high, and the core part of the activated carbon, photocatalyst, ultraviolet rays, HEPA, etc. are often defective.

3. Plant elimination method. Spider plant is used. Aloe vera, tiger tail orchid and other flowers absorb indoor pollutant gases, but plants photosynthesize during the day to absorb carbon dioxide and release oxygen, and absorb oxygen at night and release carbon dioxide, which is not good for the human body, especially for pollen and flowers who are prone to allergies.

4. Spraying of chemical reagents. Such as formaldehyde scavengers, air fresheners and other chemicals. It is the use of one odor to suppress another odor, which does not achieve the purpose of removing the source of pollution, and the use of chemical reagents will produce secondary pollution, which is not good for health.

5. Activated carbon adsorption method. Activated carbon has a well-developed internal void structure and a large surface area, which is the most effective air purification product for workers in the world today, and is a good helper for human anti-poison, detoxification and purification. However, many unscrupulous businesses on the market describe activated carbon with low adsorption value as high-quality activated carbon, misleading the public, and even disguising unactivated bamboo charcoal, charcoal, coconut shell charcoal and other carbonized materials as activated carbon, which harms consumers.

Therefore, when purchasing, distinguish between ** and do not be deceived. When purchasing, it is best to choose the products of regular activated carbon production enterprises, such as happy forest activated carbon.

How to remove formaldehyde? The dangers of excessive formaldehyde?

1.Formaldehyde removal method Plant formaldehyde removal: It should be noted that the general low pollution can choose the plant formaldehyde removal method, if the indoor pollution is less than three times the national standard, it is mild and moderate pollution, in this case, the use of plant formaldehyde can play a good effect.

Plants can be placed according to the different functional areas of the room, generally ten square meters of space, you can place two pots of plants with a height of two meters.

2.Activated carbon to remove formaldehyde: Activated carbon is internationally recognized as an expert in drug abuse, and activated carbon is used in formaldehyde removal activated carbon masks and gas masks.

Generally, the activated carbon package placed in the special indoor is to use the physical properties of activated carbon to deodorize and detoxify, without any chemical additives, and has no impact on the human body. Put two to three dishes in each room, and the indoor odor can be basically eliminated at 72 o'clock. This method can be used for medium and low pollution, or it can be used in combination with other chemical methods to remove formaldehyde and have a better comprehensive treatment effect.

3 Ventilation to remove formaldehyde: removal of formaldehyde through ventilation is a good way to reduce the content of formaldehyde, so that the indoor air circulates to reduce the content of harmful substances in the room, but this is generally not applicable in winter, many people reduce the number of ventilation in winter, so that the content of formaldehyde and other harmful substances in the room will increase, which will bring certain harm to the body, so if the conditions allow, no matter what season, or should be more ventilated.

Formaldehyde is very harmful to the human body, so we must understand what the hazards of formaldehyde are. First of all, formaldehyde can make people acutely poisoned, which has great damage to **. When formaldehyde reaches a certain level, the human body will have uncomfortable symptoms, such as hoarseness, itchy eyes, throat discomfort, dermatitis, dyspnea, and in severe cases, it will cause pulmonary edema, anaphylactic shock and liver failure.

When inhaled in excess, it can lead to death. Formaldehyde can also cause leukemia, the main reason is that the human gene mutation, resulting in damage to the human hematopoietic function, has a very strong carcinogenic effect. Therefore, it must be noted that when the formaldehyde concentration is relatively high, it must be ventilated indoors, or an air filter must be purchased, which can effectively slow down the harm of formaldehyde.

The methods of indoor formaldehyde elimination are as follows: first, consider opening all windows to effectively discharge indoor formaldehyde and other harmful gases out of the outdoors through air circulation. Secondly, the use of formaldehyde scavengers can be considered for effective removal of formaldehyde.

Finally, formaldehyde can be adsorbed by planting green plants indoors, such as cacti, which can remove some harmful gases in the air.

Formaldehyde causes the most serious damage to the respiratory system, and the best way to remove formaldehyde is to ventilate for a few days, spray with warm green tea water, dehumidify by air conditioning, and dehumidify a variety of green plants.

Formaldehyde hazards include:

1. Respiratory system, after inhaling air containing formaldehyde, you will feel poor breathing, coughing, chest tightness, and long-term exposure may cause chronic pneumonia and decreased lung function.

2. Eyes, eye conjunctiva is sensitive to formaldehyde, and long-term contact will cause symptoms such as dry eyes, tears, and photophobia.

3. Immune system, long-term inhalation of formaldehyde can damage the immune system, resulting in impaired immunity, and patients are prone to symptoms such as colds and fevers, and even lead to tumors, especially leukemia, lymphoma, etc.

4. Nervous system, inhalation of formaldehyde can lead to damage to the nervous system, and patients have symptoms such as dizziness, tiredness, insomnia, and drowsiness.

Formaldehyde treatment measures:

1. Pay attention to ventilation. It is more conservative to ventilate the new house for more than six months after it has been renovated, which is relatively conservative.

2. Putting some green plants at home can also effectively remove odors, especially pothos, spider plants, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases.

3. Activated carbon and leaf mud adsorb formaldehyde. Both are physical adsorption of formaldehyde, and at the same time, the new generation of Ye Guang mud can better adsorb formaldehyde and decompose into harmless gas, which is not easy to saturate and will not be released twice to cause pollution. It is suitable for long-term storage in wardrobes and cabinets.

4. Air purifier. Our family bought it, but I usually don't use it much, my home is in Hangzhou, I feel that the outdoor air quality is okay most of the time, and I understand that the effect of removing aldehydes is not very significant.

5. Fresh air device. Its working principle is also the implementation of internal and external air replacement, there is a certain effect of removing aldehyde, the same, for the family with better ventilation conditions, aldehyde removal is not as good as directly opening windows and doors for ventilation.

increase the temperature and humidity in the room". In order to accelerate the release of formaldehyde, we can increase the indoor temperature and humidity, because the higher the temperature and humidity, the faster the volatilization of formaldehyde, and then open the window, the ventilation will blow away the indoor formaldehyde, so that the indoor formaldehyde concentration can be quickly reduced.

The best way to speed up formaldehyde release is to ventilate, which is not only effective, but also very low-cost!

In fact, the factors that affect the efficiency of formaldehyde release are temperature, relatively high humidity, and the important thing is the concentration of formaldehyde in the indoor space environment!

If you want to accelerate the release of formaldehyde, you can start by increasing the temperature and relative humidity of the room! At the same time, try to reduce the concentration of formaldehyde in the indoor environment!

The concentration of formaldehyde in the indoor environment will have a saturation value. Once the saturation value is reached, the release efficiency of formaldehyde from furniture, panels, etc. will be extremely low, even if the temperature and relative humidity are high, there is no obvious effect!

Therefore, while opening the window for ventilation, the development of indoor air circulation is accelerated and the efficiency of indoor and outdoor air replacement is improved by using the traditional industrial control fan to blow air to the window! This is a quick way to reduce the concentration of formaldehyde in indoor space environments!

In addition, air conditioners can be used to raise the indoor temperature, and humidifiers can also increase the indoor relative humidity. On the one hand, it can accelerate the release of formaldehyde, on the other hand, it can increase the temperature difference and humidity difference between indoor and outdoor environments, and can also improve the replacement efficiency of indoor and outdoor air! But be careful not to close the doors and windows for a long time, otherwise the effect will be greatly reduced!

In practice, you can close the doors and windows for 2 hours, turn on the air conditioner and humidifier at the same time, and then ventilate, and at the same time use the industrial fan as an auxiliary!

If the operation is troublesome, the simple and effective way is to open the windows as much as possible to provide ventilation, so that the indoor formaldehyde concentration is always kept at a low value, which can also speed up the release efficiency of formaldehyde release!

There are several ways to remove indoor formaldehyde:

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 lead and formaldehyde.

However, it is important to note that the effect of plant purification is slower and needs to grow and function over a longer period of time.

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 pollutants. Activated carbon can be placed in a room or used with an air purifier to achieve the effect of formaldehyde adsorption.

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 concentration of formaldehyde in the indoor world, 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.

The easiest and most practical way is to open the windows for ventilation.

Some people say that opening windows for ventilation is too troublesome and slow, but I have to admit that opening windows is the most effective and least expensive way to remove formaldehyde in the room. Of course, it can be supplemented by some convenient ventilation means, such as using high-power fans to promote air exchange, putting some simple green plants indoors for carbon dioxide exchange and absorption in the air, and placing activated carbon for adsorption.

Secondly, there is also the experience summarized according to the personal operation of many netizens.

For different formaldehyde, different treatment methods are adopted, for example, for formaldehyde in the local air inside the room, you can open the window to ventilate it, but you must pay attention to the weather, otherwise the furniture damage caused by the rainwater infiltration caused by the mistake will outweigh the loss; For the formaldehyde-containing material glue on the surface of the furniture, sprays can be used to directly degrade; For places where there is no air circulation inside the furniture, activated carbon can be used for adsorption, and activated carbon adsorption is saturated, so pay attention to replacing activated carbon regularly; Due to the formaldehyde in some fabrics, they can be cleaned in advance to reduce part of the formaldehyde content.

You can also use a humidifier to remove formaldehyde, pay attention to when using a humidifier, be sure to close all doors and windows, wait for about eight hours, and then carry out ventilation operation, the effect is still good. In addition, I recommend a Lanfeiman photocatalyst that is very popular among netizens, it is really not a support, and there is no advertisement, spray it evenly on the surface of the furniture, spray it every other day, try to spray it in every corner, decompose formaldehyde from the root, and do not produce harmful gases in the process.

There are two methods for the numerical detection of formaldehyde. One is to detect with a formaldehyde detector, and the other is to use CMA for detection, the effect is good, depending on personal preference.

Note that no matter whether there are elderly people and children in the home, and no matter how anxious you are to move in, you must wait until all the formaldehyde content reaches the standard before you can move in, do not worry, the toxicity of formaldehyde can destroy the resistance of an adult, do not underestimate it. In addition, if you have good suggestions, you can also leave a comment and share it with more people in need.
