Can an air purifier remove formaldehyde

Air purifiers do have a partial effect on removing formaldehyde, but air purifiers are high, if people with low budgets air purifiers are not the first choice, there are various ways to remove formaldehyde, and here are several ways to save time and money, you can use them with air purifiers

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 is a more effective way to purify the air, it has a strong adsorption effect on harmful substances such as formaldehyde, 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.

3. Ventilation.

This is nature's gift to us, and it is the most economical way to remove aldehyde, as long as you open the window, fresh air will enter the room, and formaldehyde will be purified by dilution.

Fourth, the fresh air system.

The fresh air system is a system that filters the outdoor air and transports it to the room through the pipeline, and discharges the harmful substances contained in the room from the corresponding pipeline.

5. Formaldehyde remover.

Under certain conditions, formaldehyde scavengers react chemically with formaldehyde to produce other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

Most of us are office workers, and time is very limited, so if you want to remove formaldehyde from the air as soon as possible, it is best to do it in a variety of ways at the same time.

Air purifiers containing activated carbon can remove formaldehyde.

If an air purifier does not contain activated carbon, it cannot remove formaldehyde.

No, physical adsorption does not remove formaldehyde molecules.

1. The air purifier can remove formaldehyde, place the air purifier in the indoor environment, the purifier can quickly adsorb the formaldehyde substance with its strong purification ability, and even decompose the formaldehyde and other harmful substances, so the air purifier can improve the indoor air quality.

2. Activated carbon filters will be installed in the air purifier, which can adsorb formaldehyde, with the continuous progress of science and technology, there is a nano mineral crystal adsorption system on the market, and the adsorption capacity is also very powerful.

3. Air purifiers can not only remove formaldehyde, but also absorb a variety of harmful substances and haze in the air, air purifiers are very popular when there is haze, up to more than 300 will cause patients with respiratory diseases to induce asthma, so placing an air purifier indoors and carrying a small purifier can reduce the impact of haze on the human body.

OK. Air purifiers, also known as "air cleaners", air purifiers, and purifiers, refer to products that can adsorb, decompose or transform various air pollutants (generally including dust, pollen, odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.), and effectively improve air cleanliness, mainly divided into household, commercial, industrial, and building products.

Applicable places: 1. Newly renovated or renovated residences.

2. There are residences for the elderly, children, pregnant women, and newborns.

3. Residence of people with asthma, allergic rhinitis and pollen allergies.

4. A place to live for pets and livestock.

5. Relatively closed or affected by second-hand smoke.

6. Hotels and public places.

7. The residence of people who are willing to receive a high quality of life.

8. Hospitals, reduce infections and prevent the spread of diseases.

Most air purifiers can isolate particles of different diameters in the room through the filter, which can quickly achieve the purification effect, but the decoration pollutants are gaseous pollutants, and the diameter is far smaller than the particle pollutants, therefore, most air purifiers are helpless against formaldehyde, benzene and other harmful substances, so you must be cautious when choosing, and it is more reliable to choose products marked with the function of "removing formaldehyde". Comparatively speaking, a stinky machine is a good choice.

Most air purifiers on the market claim to have almost zero formaldehyde removal effect.

The inspection center purchased the top 10 purifiers for testing from a well-known e-commerce platform, and 7 of them were claimed to have the function of purifying formaldehyde. The final clean air volume (CADR) of formaldehyde removal showed that the 7 purifiers were so ineffective that they could not be ranked. A purifier with good effect runs for 60 minutes in a 15-square-meter room, and the theoretical purification of formaldehyde is less than 50%, and the CADR value is only 29m3 h.

The CADR value of the purified air pollutants should be at least 60 m3 h before it can be effective. Household formaldehyde is constantly released, and the actual effect may not even reach 29m3 h. For household air purifiers, the selling point of purifying formaldehyde is still on paper.

Song Guangsheng said. So where does the so-called formaldehyde filtration rate come from? On the promotional materials provided by the first personnel, the reporter noticed that it was indicated in smaller font: "It was obtained under the condition of "injecting formaldehyde into a 1m3 closed experimental box and starting up for 3 hours".

The disparity between the test conditions and the actual use environment makes the purification effect naturally greatly reduced.

According to industry insiders, this kind of testing is basically the manufacturer to send third-party testing, choose the testing items by itself, and settle the testing fee by itself, and the authority of the testing agency needs to be verified, but the commercialization of the testing process is very obvious. Behind the unworthy name, it indicates the inefficiency of the product. Consumers are paying for it.

The principle of an air purifier is to inhale indoor air through a motor, pass it through in-machine purification equipment, such as filters and various generators, and then send clean air to the room. In this way, the effect of purifying the indoor air is achieved. The adsorption capacity of the filter of the air purifier is very limited, which can be said to be a drop in the bucket for a large amount of formaldehyde after home decoration.

So, how do you remove formaldehyde? The best way to do this is to open the windows for ventilation.

Yes, but some of them have a limited range and need to put a few more. If the whole house is ventilated to drive away formaldehyde, the fresh air system is better.

Air purifiers do have a partial effect on removing formaldehyde.

Compared to mechanical filtration, which can only effectively remove particles above 10 microns, when the particle size is reduced to 5 microns, 2 microns or even submicrons, efficient mechanical filtration systems become more expensive and the air resistance can be significantly increased.

Filtered through the electrostatic electret air filter material, it can achieve high capture efficiency with low energy consumption, and has the advantages of low wind resistance of electrostatic precipitation, but it does not need to be connected to tens of thousands of volts of voltage, so it will not produce ozone, and because its composition is made of polypropylene, it is easy to dispose of.

Suitable for:

1. Pregnant women: Pregnant women will feel unwell in the room with serious air pollution, and will have symptoms such as dizziness, sweating, dry smoke, chest tightness and vomiting, which will have a negative impact on the development of the fetus. Heart disease is three times more likely than having a baby born to a pregnant woman who breathes clean air.

2. Children: Children's bodies are developing, the immune system is relatively weak, and they are susceptible to the harm of indoor air pollution, resulting in decreased immunity, stunted physical growth, inducing blood diseases, increasing the incidence of asthma in children, and greatly reducing children's intelligence.

3. Office people: an enviable profession when working in a high-end office building. However, in the environment with poor air quality at constant temperature and closed temperature, it is easy to cause dizziness, chest tightness, fatigue, emotional fluctuations and other uncomfortable symptoms, affecting work efficiency, causing various diseases, and in severe cases, it can also cause cancer.

Let's talk about the conclusion first: the air purifier can remove formaldehyde, but the best way to reduce the harm of formaldehyde is to open the window for ventilation, especially in summer, formaldehyde volatilizes quickly, and the effect is very good with the window ventilation. It is best to move in a newly renovated house after a summer of ventilation, especially if there are elderly people and children at home.

For the first year of moving in, it's best to use an air purifier.

There are national standards for air purifiers, among which formaldehyde CADR and formaldehyde CCM are indicators for the formaldehyde removal ability of air purifiers. Formaldehyde CADR represents the efficiency of the air purifier to remove formaldehyde, and formaldehyde CCM refers to the cumulative formaldehyde removal capacity of the air purifier. When choosing a specific air purifier, it is necessary to choose two products with high parameters: formaldehyde CADR and formaldehyde CCM.

At present, the air purifiers on the market with good formaldehyde removal effects are from professional brands, and if you want higher technical support, and are suitable for the air purifiers used by China's new house decoration families, it is recommended that Teramont (which can adsorb and decompose formaldehyde at the same time, eliminating secondary pollution; With a professional formaldehyde independent sensor, it can view the indoor formaldehyde content in real time, and the effect of formaldehyde removal can be seen, and the EU CE and the United States FCC double certification products. ）

The air purifier has a certain effect on removing formaldehyde, provided that the air purifier must have the effect of removing formaldehyde. Generally, the filter element of the air purifier uses activated carbon technology or photocatalyst technology, which has a certain aldehyde removal function, and if it is used with other aldehyde removal methods, the aldehyde removal effect is better.

Due to the increasing air pollution, people pay more and more attention to the air cleanliness index in the living environment, especially for the newly renovated family, for the removal of formaldehyde This work is more important, because it is really harmful to the human body. After the continuous development of science and technology, there are more and more equipment and methods on the market to purify the air and remove formaldehyde, and the air purifier is one of them, and it has soon become the new favorite of people to purify the air. So are air purifiers really effective in removing formaldehyde?

Air purifiers have a certain formaldehyde removal effect. If an air purifier wants to play a role in purifying the air, it generally relies on its filter element, which can achieve filtration and adsorption removal. However, if you want to remove formaldehyde, it depends on whether your air purifier has this function, and generally only the air purifier with activated carbon type and photocatalyst type has a certain aldehyde removal effect.

Therefore, whether the air purifier has the effect of removing aldehyde depends on its filter element, because many air purifiers generally only have the effect of purifying and filtering large particles of pollutants in the air, if you want to remove formaldehyde, it is best to ask the staff whether the air purifier has the function of removing formaldehyde before purchasing, to make an accurate judgment, you only need to understand whether the filter element of the air purifier uses activated carbon technology and photocatalyst technology At this stage, people use the method of removing formaldehyde is probably activated carbon adsorption, plant adsorption, Ventilation and photocatalyst, so even if an air purifier wants to remove formaldehyde, it can't get rid of these principles. Of course, when the aldehyde removal work is carried out in life, the air purifier alone can not be completely removed, if it is in summer, it can be used with the window ventilation method, if it is in winter, it can be used with plant adsorption and activated carbon adsorption and other methods to make the aldehyde removal effect better.

Air purifiers can filter fine dust in the air, and some air purifiers with special functions can indeed remove formaldehyde, and even sterilize the air, but in fact, the effect is not good, and the replacement cost of the filter element is particularly high, it is better to buy chlorine dioxide effervescent tablets.

The air purifier itself cannot remove formaldehyde, and some businesses have started to make an article on the filter element in order to increase the selling point of the air purifier. Friends who know formaldehyde must have heard of activated carbon, and this thing can adsorb formaldehyde, suppose the filter element of the air purifier is made of activated carbon, the air containing formaldehyde is pumped in, and then the formaldehyde is absorbed by the activated carbon filter, which does not achieve the effect of removing formaldehyde? But in fact, the speed and efficiency of activated carbon to absorb formaldehyde is very limited, and when the filter loses its effectiveness, the air purifier only plays the role of purifying fine dust.

Therefore, if you buy an air purifier with a filter element that is not activated carbon, then it does not have the function of filtering formaldehyde, you must know that formaldehyde is a colorless and odorless gas, which itself cannot be filtered by ordinary filters, unless it can exhaust all the air in the room, otherwise it cannot remove formaldehyde at all. Therefore, if you buy an ordinary air purifier, you will only walk the indoor air containing formaldehyde through the purifier, and formaldehyde will still exist.

Therefore, the air purifier purifies formaldehyde is completely ridiculous, although it has some effect, but the activated carbon filter must be replaced frequently, otherwise it will have no effect. The filter element of activated carbon is not cheap, you can buy an air purifier again after replacing it a few times, and a bag of food-grade chlorine dioxide effervescent tablets is less than 100 yuan, which can even be used for more than 5 years, and its effect of removing formaldehyde is simple and crude. Therefore, it is not recommended to buy this so-called formaldehyde removal air purifier, and it is better to buy something with that money.
