Is there any most effective way to remove formaldehyde?

The more effective methods for removing formaldehyde are: method 1: more ventilation, choosing to open doors and windows for ventilation is the most effective way to remove formaldehyde, which is simple and has obvious effects.

Generally, it takes 2-3 months to decorate, and we can put the decoration materials in the sun for ventilation during this time, which will be of great help and can avoid a lot of pollution. It is a simple and effective way to remove and dilute harmful gases in the room by allowing the natural circulation of indoor air to recycle. Method 2:

Place a green plant with strong formaldehyde adsorption, spider plant, which can absorb more than 80% of harmful gases indoors, and has a super ability to absorb formaldehyde. In general, 2 pots of spider plants are raised in the room, and the toxic gases in the air can be absorbed, so the spider plant is also known as the "green purifier". Saxiwei orchid can absorb more than 80% of harmful gases in the room, and has a super ability to absorb formaldehyde.

Ivy, robber removal of formaldehyde. It can decompose two harmful substances, namely formaldehyde in carpets, insulation, plywood, and xylene, which is harmful to the kidneys hidden in wallpaper. Aloe vera, it is not only a good hand for absorbing formaldehyde, but also has strong medicinal value, such as sterilization, beauty effects.

Many potted varieties have been developed, which have strong ornamental properties and can be used to decorate the living room. Method 3: Activated carbon adsorption method, activated carbon to remove formaldehyde is a relatively cheap and practical method, characterized by physical adsorption, thorough adsorption, not easy to cause secondary pollution.

For example, oracle bone particles, the physical action of activated carbon deodorizes and detoxifies; There are no chemical additives and no effect on the human body. Method 4: FFU air purifier, like activated carbon, the air purifier only targets formaldehyde in the air and cannot control formaldehyde pollution from the source.

In addition, most air purifiers filter particulate matter, such as particles in the air with a diameter of microns), can not filter formaldehyde (less than 1 nanometer, micron is 2500 nanometers, more than 2500 times larger than formaldehyde), if you want to use an air purifier to purify formaldehyde, you must carefully choose products that are really effective for formaldehyde.

Peel adsorption method is a well-known treatment method, although many people still believe in this method, but to tell you, peel treatment of formaldehyde is not scientific. The peel itself has an odor, which can cover the smell of harmful substances such as formaldehyde.

As a physical adsorption material, activated carbon can adsorb the peculiar smell produced by decoration, and can also adsorb pollutants in the air. In this way, the best way for us to remove formaldehyde is to ventilate more, and other methods can buy some plants and bamboo charcoal to put at home, and put some aldehyde if you want to be fast. Take.

to remove aldehydes. The ore crystal is placed, and nothing else, the effect is not good. Thank you!

There are many ways to reduce formaldehyde content, but what is said here is that reduction is not treatment, and the current mainstream methods are mainly divided into three categories: air replacement, adsorption, and root cause treatment;

Air replacement: ventilation method, fresh air system.

Features: This method is mainly used to dilute the indoor formaldehyde content by air replacement, and to dilute indoor harmful gases such as formaldehyde by circulating and replacing it with outdoor air, so as to achieve the purpose of reducing the content of indoor formaldehyde and other harmful gases. However, such methods treat the symptoms but not the root cause, and it is difficult to effectively ensure that the air quality meets the standards for a long time, and once the air circulation is stopped, harmful gases such as formaldehyde will still gradually accumulate and even lead to exceeding the standard.

Adsorption: air purifiers, charcoal bags, plants, all kinds of mineral crystals, etc.

Features: This type of method mainly relies on the pore characteristics of activated carbon to adsorb harmful gases in the air, or absorbs them with the characteristics of plant photosynthesis; However, in the process of adsorption, it will lead to the saturation of activated carbon, which needs to be dried or replaced regularly to avoid adsorption failure or secondary pollution. However, this method is also aimed at the harmful gases that have been released into the air, and cannot prevent the release of harmful gases from the release source.

Its efficiency is still not as high as that of ventilation.

Root cause management: formaldehyde removal company.

Features: Professional and formal formaldehyde removal companies will judge the pollution source and use different processes and products for targeted treatment, which can effectively ensure the treatment effect for a long time. However, most of the formaldehyde removal companies on the market do not have such professional capabilities, most of them are franchised or individual guerrillas, overly believe in the product effect, and only use atomization spraying and high-temperature fumigation for treatment, these two processes can not really effectively penetrate into the pollution source for treatment, and it is difficult to achieve a rational treatment effect.

Therefore, many people agree that the formaldehyde removal company is the first. Therefore, in the mixed formaldehyde removal industry, how to find a truly formal and professional formaldehyde removal company is the difficulty.

1. Regular ventilation with high temperature and high humidity (formaldehyde emission is the fastest and most effective).

2. Activated carbon, purple and black have a certain effect, the former is adsorption, and the latter is decomposition without secondary pollution. Be sure to buy vacuum packaging and treatment, ordinary charcoal has no effect.

3. Air purifier, the China Consumers Association has an air purifier effect test table, I think it can be referenced, it is more authoritative, and the Shanghai Municipal Consumer Protection Commission also has one, you can also refer to the reference, please check it.

4. Green plants, spider plants, pothos, tiger pill orchids, rubber trees, ivy, etc., more than 30 pots in my house, the effect is average, better than nothing, but it does increase air humidity, which is a fact.

5. Photocatalyst, which requires professional instruments, is very expensive, and the effect is very good. Other methods are largely negligible.

6. The deodorization of grapefruit peel and pineapple peel is just the practice of covering up the ears and stealing the bell, which only covers up the smell of TVOC gas such as formaldehyde, and does not actually solve the problem.

How to remove formaldehyde effectively?

1. Ventilation method.

The ventilation method is simple and practical, and the operability is strong, and the new house can be moved in after half a year of ventilation. However, it should be noted that ventilation can not completely remove indoor formaldehyde, for some finely decorated houses, due to the use of more decoration materials, more complex, so the ventilation time will be longer, it is best to use some formaldehyde removal products as an auxiliary.

2. Physical adsorption.

The typical representative of physical adsorption is activated carbon, which can exert its excellent adsorption effect by placing the activated carbon bag in a closed cabinet, drawer and other places with small space. It should be noted that in this case, the activated carbon will reach a saturated state after 30 days of use, and it cannot continue to adsorb formaldehyde in the air, and it is necessary to replace the new carbon bag in time.

The length of use time is positively correlated with the size of the adsorption capacity, and the activated carbon with a large adsorption capacity can be used for a longer time, such as coconut carbon, because of the rich pores, the adsorption capacity is large, and the use time is longer than that of ordinary activated carbon.

3. Chemical decomposition.

A photocatalyst is a photocatalyst that uses light energy to break down pollutant molecules into harmless gases. The catalyst is not consumed in the reaction and is theoretically permanently effective. One of the ways to use photocatalyst is to apply the photocatalyst solution to the surface of furniture for pollution control.

However, we know that gas molecules move extremely fast, and catalytic reactions take a certain amount of time, so the effect of this treatment method in practical application is not ideal.

At present, the more effective methods for removing formaldehyde are:

1.Open windows for ventilation and use some photophyll to decompose formaldehyde.

2.In the place where the furniture door is opened, put some activated carbon, algae earth.

3.Special air fresheners are used, which are generally sold in supermarkets.

4.Plants can adsorb some harmful gases, such as spider plants, ivy, etc.

I was looking for a company called Olekang in Beijing to do the governance, I think the effect is still very good, there are seven processes to do the governance, and not only the treatment of formaldehyde, they even benzene series, or something have been treated, there is no odor in the house, before the treatment said that it exceeded the standard by about two times, at first a little unbelievable, and then I specifically found a CMA agency to do the test, and they tested the same, now live in, nothing to do.

Now there are many methods to remove formaldehyde, which are roughly divided into ventilation, adsorption, and decomposition according to the principle of formaldehyde removal.

1. Ventilation. Natural ventilation: economical and environmentally friendly, with high efficiency in removing formaldehyde. Ventilation is most needed in the morning, with at least 1 hour of intermittent ventilation over a 12-hour period.

Forced ventilation: The fresh air system is commonly used, which has a good effect on removing formaldehyde. Composed of air supply and exhaust system, it discharges indoor pollutant gas and sends fresh air to the outside, and the ceiling-type full heat exchanger is the current mainstream fresh air system scheme.

2. Adsorption. Commonly used is activated carbon, which is a molecular sieve with tiny internal pores capable of adsorbing various substances, including formaldehyde. If you have used activated carbon to remove formaldehyde, please win by quantity, not by quality.

The adsorption saturation time is uncertain, mainly depending on the pollution degree of indoor formaldehyde, benzene and TVOC.

3. Decomposition. Photocatalyst: Photocatalyst has the best efficiency in removing formaldehyde under ultraviolet light. Ordinary photocatalysts are not suitable for indoor use because there are almost no indoor ultraviolet rays; As for visible light photocatalysts, the formaldehyde removal efficiency is unknown, and it needs to be sprayed by professionals, so it is not recommended to buy them yourself.

Formaldehyde scavengers: ammonia, chlorine dioxide, hydrogen peroxide, etc. are commonly used, and some rely on formaldehyde to be easily soluble in water to achieve the formaldehyde removal rate in the experimental cabin. Formaldehyde removal efficiency is mostly high, but it can be harmful to the human body and furniture.

Mumena Pure Stone: Contains CLO purification factor, black and white particles, and has a high formaldehyde removal efficiency. Decomposes formaldehyde, granular products are harmless to the human body and furniture.

Formaldehyde in China's newly renovated houses generally exceeds the standard, and the harm of formaldehyde can not be ignored, especially for babies and children, pregnant women, the elderly and other weak resistance The harm is more serious, so before moving in, you must ask a professional institution to do testing, if there is an exceedance, you must treat it and reach the standard before you can move in. Indoor planting of green plants, activated carbon, peel adsorption, etc. can play a certain role in improving the air environment, to open more windows for ventilation, but can not remove the harmful substances of the decoration pollution source, the most effective is the photocatalyst to remove formaldehyde, the characteristics of the photocatalyst is the use of oxygen molecules and water molecules in the air to convert the contact organic matter into carbon dioxide and water, itself does not change, but can promote the chemical reaction of the substance, theoretically the validity period is very long, the maintenance cost is low. At the same time, titanium dioxide itself is non-toxic and harmless, and has been widely used in various fields such as food, medicine, and cosmetics.

Formaldehyde is the most well-known representative of indoor chemical pollutants, and even to some extent, excessive formaldehyde has become synonymous with indoor air pollution.

1. The most common way to remove formaldehyde indoors is to open windows for ventilation, and this method has almost no cost. But the ventilation method also has disadvantages, first of all, the location of the house should be good to achieve the effect of ventilation, and secondly, the formaldehyde in the decoration materials is in a state of continuous release, and it is impossible to completely remove formaldehyde through window ventilation, it can only play an auxiliary role in removing formaldehyde.

2. Green plants, aloe vera, cactus, 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.

3. Activated carbon is a more effective method to purify the air, it has a strong adsorption effect on formaldehyde and other harmful substances, and the smaller the particles, the better the adsorption effect. It should be noted that most activated carbons have certain adsorption limits, and once saturated, they will no longer be absorbed, but will appear desorption, releasing absorbed harmful substances.

5. Professional formaldehyde removal companies can also quickly remove indoor formaldehyde and harmful substances, but because China's indoor air purification industry started late, there are no particularly strict scientific specifications, in the formaldehyde removal company, there are many unprofessional and irresponsible companies, we must keep our eyes open when choosing.

6. Ventilation is an indispensable method for 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

In addition to formaldehyde, don't do useless work, CCTV experts teach you the most effective method

Formaldehyde removal in new houses has basically become an indispensable part of the decoration, and the method of removing formaldehyde is also a word, each with its own statement and basis, so which methods are really effective? Let's take a look at what the experts in the CCTV program have to say.

Useless work 1: activated carbon adsorption is easy to saturate

After experimental measurement, the adsorption effect of the front end of the activated carbon is indeed good, but its adsorption capacity is certain, and after the adsorption reaches saturation, it not only has no purification effect, but also releases it with the increase of temperature, and may even cause secondary pollution.

Useless work 2: green plants have little effect on purification

In the same test, we also measured the green plants, such as: spider plant, pothos, etc. do have a certain purification effect, but the actual purification effect is not ideal, unless every corner of the home is filled with green plants.

Useless work three: onion grapefruit peel is almost useless

Onions, grapefruit peels and other soil methods are just a simple smell masking, there is no effect of removing formaldehyde at all, experts pointed out that these soil methods to remove formaldehyde is completely covering the ears and stealing the bell, formaldehyde has always been there, there is no purification effect at all, it is not recommended to use this method to remove formaldehyde.

So, apart from these useless efforts, what are the methods that are really worth using? Let's take a look at the most effective methods for removing formaldehyde given by experts.

1. Strengthen ventilation

Ventilation has always been an effective way to remove formaldehyde, we not only have to open the windows, but also to open the doors of furniture and cabinets as much as possible, and for poorly ventilated rooms, fans can also be used to increase ventilation.

2. Formaldehyde is removed by algae

Baizao is a mineral purification material, the reason why it is recommended is because it is not only faster than activated carbon adsorption and purification, and the key is that it has the function of decomposing formaldehyde, so that you can not need to dry, and there is no need to worry about adsorption saturation, especially suitable for people who are in a hurry and have no time to dry and take care of it.

3. Air purifier

Air purifier is a popular method of removing formaldehyde in recent years, and with the continuous improvement of technology, the effect of removing formaldehyde is also obvious. However, it needs to be used with the windows closed, and each room needs to be equipped with one to play a role, so it is not suitable for large-scale use, and is more suitable for use at night or when it is inconvenient to open the window to assist in purification.
