How to remove formaldehyde at home, how to remove formaldehyde at home?

The most economical and effective way to remove formaldehyde is to open windows for ventilation.

On the one hand, the dilution of fresh air can dilute indoor pollutants and facilitate the emission of indoor pollutants. On the other hand, it helps to release toxic and harmful gases in decoration materials as soon as possible. Open the window every day to choose the right time, generally after 10 o'clock in the morning, divided into morning, noon and evening ventilation for 20 minutes.

In the absence of ventilation conditions, or when ventilation is not suitable, indoor purification can be carried out with the help of professional air purification devices, such as air purifiers, activated carbon, etc.

In addition, professional formaldehyde testing can be done with a ppm detector, or you can find a testing agency with CMA qualification for on-site testing. However, the company of testing and governance should be separated, and it is important not to be both an athlete and a referee. After the governance is completed, it is best to find a third agency for acceptance.

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.

The methods of removing formaldehyde in the home include ventilation method, deodorant method, activated carbon adsorption method, photocatalyst decomposition method, etc., and the specific methods are as follows

1. Ventilation method.

Through the circulation of indoor air, the content of harmful substances in indoor air can be reduced, thereby reducing the harm of such substances to the human body. The doors and windows in the room are often closed, and the indoor and outdoor air cannot be circulated, not only the formaldehyde content in the indoor air will increase, but also the radon gas will continue to accumulate, and even reach a high concentration.

2. Deodorant removal method.

Formaldehyde deodorant can capture and decompose harmful pollutants such as formaldehyde, benzene and ammonia, kill germs and harmful microorganisms of mites, purify the air and eliminate odors.

3. Photocatalyst decomposition.

Photocatalyst is a general term for photosemiconductor materials with photocatalytic function represented by nanoscale titanium dioxide, which is coated on the surface of the substrate and produces a strong catalytic degradation function under the action of ultraviolet light and visible light, which can effectively degrade toxic and harmful gases in the air.

4. Activated carbon method.

Because activated carbon has a special physical structure, it has a good adsorption effect, and it can absorb harmful substances such as formaldehyde in the room.

If you don't deal with the new car when you buy it, there are some cars that are five or six years old, and when you open it, there is still a very heavy "leather smell", not to mention the uncomfortable smell, but also pay attention to whether there is still a formaldehyde problem in the new car. Therefore, the new car to buy to take some ways to solve the problem of excessive formaldehyde in the new car.

1. Ventilation. Ventilation is the most economical method and has no cost, but it is less realistic to ventilate a new car for a long time than a new house.

2. Activated carbon. Activated carbon adsorption is a relatively common way to remove odor, and the effect of adsorbing formaldehyde is relatively small.

3. Ye Guangni. This material is more dense in pores, which is better in adsorption and decomposition of formaldehyde, and of course can also achieve the effect of deodorization.

4. Photophyllin. If you want to take effect faster, you can use photophyll to treat the objects in the car, which can decompose formaldehyde from the source and freshen the air.

1. Ineffective method.

Plants (pothos, tiger piran, fern, etc.), calculated by 100 square meters, need to be placed in about 300 pots to effectively remove formaldehyde, and the ornamental effect is much greater than the effect of removing aldehyde.

Activated carbon can only absorb a small amount of free formaldehyde in indoor air, and cannot be absorbed for a long time, and dust will quickly occupy the absorption gap of activated carbon.

Air purifiers, filters refer to the characteristics of activated carbon, and the replacement cycle is short** expensive.

2. Cheap method.

Airy. Ventilation is a more effective way to reduce indoor formaldehyde without spending money, but the time is relatively long, many practical inferior materials decoration projects, ventilation time may be as long as 1-2 years, it should be pointed out that ventilation is not called ventilation when the window is opened, but the indoor can have the hall wind, only open the window without the convection of the wind, can not take away the free formaldehyde in the air; In addition, if there are more non-solid wood panels used in decoration, ventilation alone is not enough, and with future life, it may gradually spread and accumulate indoors.

3. Practical approach.

Now the development of science and technology, formaldehyde is no longer an uncontrollable substance, photocatalyst, biological enzymes and other catalytic effects, can effectively and quickly reduce formaldehyde content, long-term formaldehyde removal is not the best, but in the choice of formaldehyde removal company must be cautious. Formaldehyde control agency, it is recommended that you compare from the following aspects: first, whether the aldehyde removal products have various national testing qualifications, which is the guarantee of family safety; secondly, whether the service technician has construction qualifications or not, which is the guarantee of the governance effect; Finally, whether there is a real test report, which is the guarantee of life safety.

There are some roadside guerrilla workers, this type is not recommended, although it is cheap, but it does not guarantee safety. To sum up the above conditions, you can screen out a more suitable formaldehyde treatment institution.

Formaldehyde produced after the renovation of a new house is the most distressing, and if you want to remove formaldehyde quickly, it is very important to use the right method. However, there are too many methods on the market to remove formaldehyde, it is difficult to distinguish the true from the fake, and the screening is dazzling.

1. Wise Stone.

It has regular honeycomb voids inside, its specific area is huge, can efficiently adsorb formaldehyde, its adsorption capacity is strong, can reach more than 20 times of the traditional activated carbon, not only the adsorption capacity is large, but also has the function of ion exchange, can decompose formaldehyde and other harmful substances into harmless carbon dioxide and water, without replacement can be used for a long time. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Ventilation.

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.

3. Activated charcoal.

Activated carbon has the function of adsorbing formaldehyde and other harmful substances, but activated carbon does not have the function of decomposition, so the adsorption capacity is limited, easy to saturate, and needs to be replaced frequently, otherwise it will become a new pollution source to emit harmful substances to the outside, resulting in indoor secondary pollution.

Fourth, photocatalysts.

The main principle of photocatalyst is that the spray will adhere to the surface of the object to form a strong film, on the one hand, it will slow down the release of formaldehyde, on the other hand, it will contact with the film during the release process, and oxidize formaldehyde by using the photocatalytic performance of the photocatalyst. However, in daily life, the film may oxidize and wear, and the effect will be halved

Fifth, high temperature.

In the case of high temperature, it can promote the conversion of formaldehyde in the bound state into free formaldehyde and reduce the total content of formaldehyde, because formaldehyde penetrates deep into the board, although formaldehyde cannot be completely removed, but its effect is still very obvious.

In order to better reduce the formaldehyde concentration in the home environment, in the process of decorating the new house, try to control the quality of decoration materials and choose materials with relatively low formaldehyde content.

In closing doors and windows, opening curtains, exposing to the sun, increasing the room temperature to more than 30 degrees, and putting some activated carbon to adsorb and reduce the concentration of formaldehyde, it is conducive to the volatilization of formaldehyde from furniture and boards with high concentration. Then, open the windows for ventilation for more than an hour at night, and then close the windows again, twice a day, for 8-10 hours each time. After repeated for a week, the formaldehyde concentration will decrease significantly.

Note that it is not possible to live in the room at this time.

Then take the method of adsorption by plants, etc.

This method works best! Many of my friends have used it, and it works better than any other method.

Placing various fruit skins such as pineapples and the like only masks them with smell does not absorb much formaldehyde.

None of the formaldehyde removal products on the market are easy to use and effective.
