120 square air purifier, can an air purifier remove formaldehyde

Everyone knows that it has just been renovated.

Finished with a new house. It is not possible to immediately host, because the formaldehyde of indoor air is relatively high, which is not conducive to physical health, and the window must be opened for ventilation for a certain period of time before moving in. But the finishing materials.

Formaldehyde is released slowly, and even if ventilation treatment is done, formaldehyde may be released in small amounts. There is an electrical appliance called an air purifier.

Many people will use it to remove formaldehyde from the room, then air purifiers.

It can remove formaldehyde.

Is it? Is it useful to remove formaldehyde with an air purifier?

Can an air purifier remove formaldehyde?

1. After ventilation, close the door.

After 6 hours, the formaldehyde concentration increased. Ventilation state, the mass concentration of formaldehyde is, closed for 3h, the concentration of formaldehyde has reached the standard value of 12h in the "Indoor Air Quality Standard (GB T18883-2002)", after which the formaldehyde concentration continues to rise, after closing the doors and windows for 5 hours, the formaldehyde concentration reaches, and the upward trend slows down after 6h, and basically reaches the balance.

2. Close the doors and windows and open the purifier at the same time, and the formaldehyde value decreases significantly. Although the purifier was on after closing the doors and windows, the formaldehyde concentration still increased rapidly, and there was a downward trend after 2 hours, and the formaldehyde release rate and purification efficiency of the purifier reached a balance after 3 hours. In this process, although the formaldehyde has increased to a certain extent, the formaldehyde concentration does not exceed the standard value of 12h in the "Indoor Air Quality Standard (GB T18883-2002)" within 6h, which shows that the purifier will have a better purification effect when the formaldehyde is released at the same time.

Formaldehyde removal method is recommended

1. Open window ventilation method: Formaldehyde is raging, and most people will choose to dry it for less than a month and more than a year after decoration. However, what we have to know is the average family room.

The window will be designed at a position of more than one meter above the ground, and the density of formaldehyde is higher than that of air, which is easy to precipitate, and it is still difficult to remove formaldehyde even if the window is opened for ventilation. In addition, most harmful substances are released slowly, up to 3-15 years, and it is by no means a few months of ventilation that can solve the problem, so opening windows for ventilation can only be used as an auxiliary method, not as an absolute method that can remove aldehydes.

2. Green plant aldehyde absorption method: In addition to formaldehyde, many people pin their hopes on spider plants.

Aloe. and other plants to adsorb. In fact, plants have a rather limited ability to breathe, usually in micrograms (parts per million) formaldehyde levels. such as rooms.

The formaldehyde in the interior exceeds the standard, and thousands of potted plants need to be placed and continuous light to have a certain effect. Therefore, relying only on green plants to absorb aldehyde can only be used as an auxiliary method, and can never be used as an absolute method to remove aldehyde.

The above describes the comparison of two experiments, the experiment clearly shows that the air purifier is useful to remove formaldehyde, but the function is limited, if for a long time, it is still necessary to open the window for ventilation, and replace the indoor air to ensure that the indoor air is fresh. Many people will also use all the plants that remove formaldehyde to convert formaldehyde, and this method also has a certain effect. Whether it is a purifier to remove formaldehyde, or a plant to remove formaldehyde, it can play an auxiliary role.

It is necessary to look at the indoor formaldehyde content, if it is exceeded, it is recommended to ask the indoor environmental protection enterprise to govern; If it does not exceed the standard, please buy an air purifier with photocatalyst, but this ** is more expensive than a purifier with activated carbon (this will be saturated).

Air purifiers cannot completely remove formaldehyde, most air purifiers are composite filters, with a layer of activated carbon, which can physically adsorb formaldehyde, and some have chemical components that can catalytically decompose formaldehyde, but the filters need to be replaced in time.

You must know that formaldehyde emissions in the home environment can be as long as 15 years! When it comes to formaldehyde removal, there are now many household formaldehyde removal services that use chemicals to reduce formaldehyde content, but it is very likely to cause formaldehyde**. What plants, fruit skins, activated carbon, adsorption capacity is very limited, and it will be emitted twice, the most effective way is to open the window for ventilation, and directly dilute and discharge the indoor air with formaldehyde with fresh air.

Air purifiers now also have a lot of products for formaldehyde, but the actual chemical decomposition or physical adsorption may cause secondary pollution, and the decomposition and adsorption are limited, and the filter needs to be replaced in time.

It is recommended to directly install Shenghuan Lunshen new fan, which can achieve 24 hours x 365 days of ventilation and filtration, which is a direct solution to the problem of no secondary pollution.

According to the data released by authoritative institutions, the top 10 ranking brands of air purifiers are: Bingzun air purifier, blue air air purifier, health pro air purifier, Honeywell air purifier, Denice air purifier, Stevo air purifier, Austin air purifier, Xiongjin Haowei air purifier, Whirlpool air purifier, and Aegison air purifier.

1. Bingzun air purifying Natal finger.

In 2022, Benshion was recommended by the ** TV station CCTV to be on the list, we must believe in the power of the brand!

Bingzun air purifiers have always been imitated and never surpassed!

The sterilization rate of BS-P8 is as high as that of Bingzun air purifier, releasing 10 million cm3 negative ions, formaldehyde CADR up to 554m3 h, particulate matter CADR up to 900m3 h, particulate matter CCM up to P4 level, formaldehyde CCM up to F4 level. The performance parameters of the Bingzun air purifier are so terrible!

Bingzun air purifier uses five layers of purification: 1. Negative ions.

High-voltage electric shock production holes are used to produce ammonia anion ions to neutralize and eliminate free positively charged dust, bacteria, and viruses in the air. 2. Sintered activated carbon. Sintering activated carbon removes harmful gases such as formaldehyde, benzene, and TVOC, generates water and carbon dioxide, and super-filters radioactive substances such as formaldehyde and benzene.

3. Antibacterial HEPA filter. Filters allergens that can be inhaled into the lungs, such as secondhand smoke, pollen, pet hair, etc. 4. Formaldehyde buster filter.

Efficient removal of harmful viruses such as H7N9, bacteria, mold spores and fine particles larger than 20 nanometers. 5. a pre-filter. Absorbs dirt such as hair, particles, dust, etc., and prevents respiratory diseases.

2. Blue Air air purifier.

Blue Air air purifiers belong to indoor air purifiers, home air purifiers, medical air purifiers, hotel air purifiers, HEPA filter air purifiers, negative ion air purifiers, cold catalyst air purifiers and other categories of air purifiers. It is a good brand in the air purification industry.

3. Health Pro air purifier.

Health Pro is an air purification equipment brand under Beijing Ruibo Meijia Commerce, which is mainly engaged in providing indoor purification solutions. Health Pro is a registered brand of air purifiers manufactured under the IQ Air AG brand in China.

4. Honeywell air purifiers.

Honeywell air purifiers instantly absorb odors and clean the air. Honeywell air purifiers are a good product for air purification, and the purification function is bland.

5. Dennis air purifier.

Denitis is a relatively mature air purifier company for air purifier production technology. The filtration effect for bacteria, dust, allergens and other substances is strong, but the feedback from customers on the negative side of formaldehyde is average, so this ranking ranks fifth.

1. The air purifier cannot remove formaldehyde.

2. The core principle of the air purifier is the internal circulation of the equipment, which uses the physical filtration method as the main cleaning method, in addition, it also comes with an adsorption filter of activated carbon, and some brands even add electrostatic precipitation and ozone sterilization, which can effectively purify the air.

3. From the above analysis of the principle of air purifier, if you want to remove formaldehyde, a large part of it is adsorbed by activated carbon, which has a strong adsorption capacity, which can effectively remove odors and purify water sources, not to mention air purification.

4. However, in actual use, the activated carbon adsorption capacity of the air purifier filter is really limited, and if the formaldehyde of the new house has been continuously emitted, it cannot be removed by the activated carbon in the air purifier alone.

5. Therefore, if you want to remove formaldehyde, just using an air purifier will have a bad effect on the removal of formaldehyde. At the same time, when using an air purifier, there is no ventilation in the room, which is likely to cause the indoor pollution to deepen, so it is best not to use an air purifier in addition to formaldehyde.

Air purifiers can indeed help us purify the air, but if you want to remove formaldehyde, it is best to seek other methods, so the effect of air purifiers on removing formaldehyde is not very good.

Air purifiers can reduce the formaldehyde content of indoor spaces to a certain extent, but they cannot completely remove formaldehyde.

The air purifier uses the principle of filtration and adsorption to adsorb, decompose and transform the odor in the air, so as to achieve the purpose of purifying the air.

There are two types of air purifiers: active and passive, and active purifiers refer to various products that will continuously release formaldehyde into the air to remove formaldehyde. When using this type of purifier, it is necessary to pay attention to the quality and decomposition efficiency of the product itself released, and whether it will cause secondary pollution of indoor air.

Passive air purifiers, most of which are filtering purifiers, inhale indoor air, and then adsorb formaldehyde molecules and other particles through an activated carbon filter, so as to achieve the purpose of purifying indoor air quality.

Precautions for the use of air purifiers

1. When using an air purifier, first pay attention to the placement position, put it in the middle of the room, this position is also the highest efficiency of air circulation, if it is placed in the corner, the purification range will be narrowed, not average enough. At the same time, it should not be close to the wall or too close to the furniture, and the distance of 20 cm should be kept around the sail to be more conducive to air circulation.

2. The air purifier needs to last for a long time before it can have a health standard, which is the same as the refrigerator, so when using it, you should know that it is not effective for a while, and you need to turn it on for a long time. You can adjust its gear, for example, you can use a large wind stall to quickly filter the air for half an hour before the machine is turned on, and then turn it to a small wind stall or set it to sleep, turn on the purification function, and prevent too much noise from affecting the rest.

The vast majority of air or air purifiers on the market use the principle of physical adsorption to remove formaldehyde. When the air purifier is turned on, the polluted air in the room is sucked into the machine, and the formaldehyde pollutants are adsorbed through the activated carbon filter. However, this process is equivalent to "sponge water absorption", which will always reach a limit value, and when this limit value is reached, the activated carbon will reach a saturation level, and naturally there is no good adsorption effect on formaldehyde pollution.

You can only replace the filter in time to keep the air purifier running efficiently and maintain its purification efficiency.

If the indoor formaldehyde concentration is high, the cost of replacing the activated carbon filter is relatively large. In fact, the ordinary live vertical carbon filter formaldehyde removal air purifier is not a wise choice.

Different from the vast majority of air purifiers on the market, the formaldehyde purification technology used in the German Seiko Neusenberg formaldehyde removal air purifier is a unique MSD formaldehyde decomposition patent technology, from the literal meaning we can know that the difference between the ordinary activated carbon filter adsorption formaldehyde, formaldehyde decomposition technology is directly from the molecular weight level of the pollutant itself, to use molecular sieve' Sift out 'formaldehyde, toluene, TVOC and other polar pollutants, ensure priority adsorption and decomposition, decompose these pollutants into carbon dioxide and water that are harmless to the human body, and will not cause secondary pollution of pollutants, so as to achieve a harmless treatment of pollutants, the advantages are obvious.

Nowadays, many people have bought air purifiers to improve air quality. So can an air purifier remove formaldehyde? PChouse will take you to find out.

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. The air purifier will be installed with an activated carbon filter, which can adsorb formaldehyde, with the continuous progress of science and technology, there is a nano mineral crystal adsorption system on the market, and its ability to adsorb harmful substances is 6 9 times that of ordinary activated carbon brother.

3. Air purifiers can not only remove formaldehyde, but also absorb a variety of harmful substances and haze in the air, since 2013, China's haze situation has become increasingly serious, up to more than 300 will cause respiratory diseases to induce asthma, so in the indoor placement of an air purifier and carry a small purifier, can reduce the impact of haze on the human body.
