How to create aldehyde-free life, how to remove formaldehyde air purifier indoors
The progress of the times has brought about major changes in the way of life. The country town has become a high-rise building, and the simple outdoor sports have become indoor gymnasiums and gymnasiums. Contemporary people spend more than 90% indoors. How do you guarantee indoor air quality? In the years before the smog was seriously jeopardized, people’s perception of PM2.5 gradually became clear, and they tried their best to reduce the harm to the body and hide inside the closed door.
Is the air quality at home good? In fact, the indoor air pollution level is not weaker than the outdoor, and there are data showing that indoor air quality is unqualified as high as 74%. The main source of pollution is formaldehyde exceeding the standard. Less than 5% of the air quality is qualified within one year of renovation, and less than half of them are qualified within three years. The house that has been renovated for 3 years is the research object, and it is carried out at 16°C-38°C, and the base number is 6482 households, and the unqualified rate reaches 74%. In addition, the office is the hardest-hit area, and most businesses will start working after the renovation. In such a bad environment, employees will be the biggest victims.
The transparency of the media allows us to see more news, free formaldehyde in the room, and every tragic case gives us an alarm. Except for aldehydes, don’t be lucky. Some common “experience” misunderstandings in addition to aldehydes 1. The sense of smell has nothing to do with harmful other concentrations. It is very risky to stay when you smell it. The individual’s personal sense of smell is different. Many harmful others are colorless and odorless. It is unscientific to judge indoor air quality by simply smelling. To determine the indoor air quality, this requires professional equipment to assist. 2, the window ventilation is not a once and for all The release cycle of formaldehyde is as long as 3-15 years. In the first three years, it is a dense divergence period. Even if it is effectively ventilated to release formaldehyde before occupancy, the pollutants will be slowly released according to the characteristics of formaldehyde. If it stays in such an environment for a long time, it will also increase the risk of cancer. The presence of formaldehyde is divided into three types: free, adsorbed, and combined. Only the free form of formaldehyde can be eliminated at a 4 times wind speed.
3. Green plants are not very useful for removing aldehydes. It is more difficult for them to purify the indoor air by green plants. Green plants are only an auxiliary means for indoor environmental management. When indoor air pollution is mild, plants can also contribute a force; when indoor air pollution is serious, plants can not only help but will be smoked by harmful gases.
4, vinegar, air freshener, water, tea to formaldehyde is a cover Some consumers will use vinegar, air fresheners, and grapefruit peels to remove odors from new homes. Experts say that vinegar is an acidic substance that reacts with ammonia in the air, but it is not good for adsorbing formaldehyde. The use of air fresheners will only cover the ears and use a scent to cover up another odor without any adsorption or decomposition.
5, an air purifier can effectively adsorb and decompose formaldehyde Air purifiers have been well received by consumers in recent years, not only to resist particulate matter but also to purify pollutants such as formaldehyde and benzene.
The air purifier is a kind of household environmental protection electric appliance that has accumulated a variety of aldehyde removal methods. The activated carbon filter mesh has been upgraded and modified, and the activated carbon particles are used to adsorb formaldehyde molecules and are not suitable for saturation. At the same time, HEPA filter dust removal, high-efficiency catalytic decomposition enzyme purification technology, and other methods are adopted, and indoor formaldehyde molecules are adsorbed reasonably and effectively.

The first step is to clarify the large classification of net products.
the first sort HEPA filter type HEPA – Abbreviation for High-Efficiency Particulate Air Filter, which means a high-efficiency air filter. When filtered with HEPA, the air can pass completely, but fine particles in the air are quickly intercepted.
Achieving HEPA standards means that this filter is effective at intercepting 0.3-micron particles at least 99.99%. By using HEPA combined with activated carbon to make a composite filter, it is possible to simultaneously adsorb particulate matter and formaldehyde gas.
H14 HEPA filter used by Miwei
Of course, some manufacturers will add sterilizing cloth, primary filter, negative ion, cold catalyst, ultraviolet lamp, etc. to assist in purification in order to increase product function. However, all purification is mainly based on HEPA filters and activated carbon. Therefore, 90% of manufacturers have chosen this purification method.
in conclusion Advantages: mature technology, high purification efficiency, high CADR value of formaldehyde and particulate matter. Disadvantages: The filter needs to be replaced regularly, and the wind resistance will generate noise.
The second type of electrostatic dust collection The high-pressure discharge allows the particles to be charged, and the built-in dust box releases the opposite-charge to absorb the particles. For the principle, please read the third-grade physics textbook. Purification of formaldehyde is also the oxidative decomposition of formaldehyde molecules by ion discharge
in conclusion Advantages: no need to replace consumables, but regular high-frequency cleaning. Disadvantages: It can remove the dust, can not remove the poisonous gas, the efficiency is lower than the mechanical type, slow, easy to produce ozone, and is rated as the worst purifier by the US market.
Understand the most important indicators of buying empty net products The current empty net market can basically be divided into four major factions: Europe, America, Japan, Korea, China, and the new generation. A total of 306 brands, large and small, have been gathered, including many domestic and foreign traditional home appliance giants such as Sharp, Panasonic, Haier, and Midea.
How to choose so many brands? Of course, you must first understand the most powerful reference data. The new national standard “GB/T18801-2015” for air purifiers re-regulates the four parameters of the air net industry.
Understand those key core “buy” points Core buy point:
Purification effect The main pollutants that need to be purified this year are smog PM2.5, pollen, haze, soot and so on. The purification effect mainly depends on the CADR value of the machine’s particulate matter, which is currently concentrated in the market at 200-500m3/h. The time required for the purification of various particulate matter CADR values is completely different for different areas. (Test room height is set to 2.5m) ▼
It can be seen that if the 20m2 bedroom needs to be cleaned, an air purifier with a CADR value of 300-400m3/h can be fully satisfied. If the 50-flat living room wants to be quickly cleaned, it may be necessary to choose a CADR value of 500 or more.
Miwei’s CADR value of 728 is much higher than the purifiers of various brands on the market.
In addition, if you mainly want to purify formaldehyde, you must check the formaldehyde CADR value of the purifier. At present, the common CAD value of formaldehyde is 100-300 m3/h. Since the amount of formaldehyde released in each space is different, the best way to quickly remove aldehydes for new homes is to open windows for long periods of time.
l core buy point: Lifetime The CCM, which has been standardized by the new national standard, also intuitively reflects the endurance of an empty net product. According to the requirements of GB/T18801-2015, the empty net is placed in a 20m2 room. Under the moderate pollution condition with a pollutant concentration of 150μg/m3, the daily processing capacity is 25mg. Different levels of CCM can How many days are you using?
That is to say, in the case of ensuring the CADR value, the life of a filter is of course as long as possible.
Miwei’s CCM value is greater than 12,400, which is equivalent to 10 times P4, which is far more than other brands on the market.
Value-added buy points: Dehumidification function In short, the function of adding a humidifier to the air purifier is to use ultrasonic waves to turn the tap water in the water tank into water vapor. This feature is very practical in the winter in the north, but there are more security risks.
Value-added buy points: Negative ion Unlike the electrostatic air purifier, the negative ion function is only used as an added value function. Scientific research has shown that negative ions do have a positive effect on health. But no one can accurately say exactly how much it works.
l Value-added buy points: APP function In the era of Internet promotion of big data, more and more brands are willing to develop an APP to make tough products more intelligent and more practical. For example, as long as the mobile phone can remotely control the home’s empty-net products, it can achieve a series of functions such as early purification. At the same time, this app can also reflect the outdoor air quality in real-time, and even record the daily purification.
Value-added buy points: Numerical display This function depends on whether the purifier is an infrared sensor or a laser sensor. The cost and effectiveness of the two are very different.
in conclusion:
Value-added buying points will not affect the purification ability of the air purifier. However, in the actual use process, there is a machine that can be visually displayed, which is still very powerful. And the most easily overlooked but extremely important point, the cost of consumables in the later period – the unit price of the filter and the frequency of replacement.

Entering the summer sky becomes clearer, there is no spring sand, no autumn dryness, and winter smog, many people will feel the air quality has improved. Especially after catching up with the rain, many people like to turn off the air purifier to open the window or ventilate in nature to enjoy the blue sky. But what is little known is that behind this kind of enjoyment, there is still a hidden danger. There are still shocking air pollution under the dome, and these pollutions are not elsewhere, just in the room where we are the longest in the day. People spend at least 18 hours a day indoors. In other words, people spend nearly three-quarters of their lives indoors. Therefore, the quality of indoor air directly affects the quality of human life.
Today, everyone knows that winter should be protected from smog, but it ignores the summer TVOC. The so-called “TVOC” refers to indoor organic gaseous substances, also known as total volatile organic compounds, including benzenes, alkanes, aromatics, alkenes, halocarbons, esters, aldehydes, ketones, etc. Toxic and harmful gases in the air. There are many sources of pollution indoors, which are the same in both winter and summer. Especially in summer, the temperature is high, and these harmful substances are more serious in the room. The release of indoor pollution such as formaldehyde is greatly affected by temperature, and the indoor and outdoor temperatures are high in summer, so it is easy to cause indoor pollutant concentration to exceed the standard. For every 1 °C rise in room temperature, formaldehyde volatilized from wooden furniture and flooring will increase the concentration of formaldehyde in the air by 0.15 to 0.37 times. Therefore, the volatilization of paint flavors such as benzene and ammonia is more serious in summer than in winter, and radioactive cesium is often contained in household tiles. This serious carcinogenic gas also spreads with increasing temperature. In addition, there are more air conditioners in summer, indoor ventilation is not ventilated, and indoor pollutants remaining in the decoration gather. Many household air conditioners do not clean and cause secondary pollution. The bacteria and microorganisms are gradually deposited, and cold air with harmful substances is added. After the respiratory tract, not only will people feel dry mouth and mouth, there will be mild cold symptoms, and in severe cases, it will cause various respiratory diseases, which is what we often call “air conditioning disease.” The World Health Organization has listed indoor air pollution as a top 10 threat to human health, including hypertension, hypercholesterolemia, and obesity. The main culprit of respiratory diseases and intestinal infections and even leukemia, which are predisposed to infants and young children, are also closely related to indoor air pollution.

Do you need an air purifier in the summer? Life is telling you!
As soon as summer arrives, Air conditioning is used frequently, But shut the air purifier! Is the air purifier Is it really a seasonal home appliance? Do you not need to use an air purifier in summer? Maybe a lot of people will think, The outdoor smog is serious in autumn and winter. The air quality in the room should also be poor, but once in the summer, The outdoor smog is gone, Is it more necessary to use an air purifier in the room? The answer is yes.
Hear what the experts say Ms. Wang Ping, a professor of respiratory diseases at the 306 Hospital of the People’s Liberation Army, told reporters that indoor air pollution will increase 40% of ischemic heart disease, 40% of strokes, 11% of chronic lung diseases and 6% of lung cancer. Although the air is invisible and undetectable, air pollution has seriously affected human health.
Closed indoor pollution in summer The Health Education Association has also issued a report stating that summer is a season of high-sensitivity during the year, and indoor air pollution is four to five times higher than outdoor. Summer is the peak period of using air conditioners. While enjoying the cool breeze in a closed air-conditioned room, it ignores the pollution of indoor air and has seriously jeopardized our physical and mental health.
Summer temperature rises, formaldehyde release accelerates In summer, the air purifier first needs to go to formaldehyde to have a good effect. In summer, the temperature rises, formaldehyde enters the active period of volatilization, and the concentration of formaldehyde in the new house increases, and the phenomenon of excessive formaldehyde appears. Every room temperature rises at home
Indoor air conditioning pollution The indoor air is not circulating, and the accumulation of pollutants is increased. In summer, the temperature is high. People turn on the air conditioner to cool down and close the doors and windows. The indoor air is dull, the temperature is high and humid, and the release rate of pollutants will be accelerated. If the doors and windows are closed for a long time, the pollutants will be closed. It cannot be effectively volatilized. Over time, family members may experience dizziness, nausea, coughing, and even difficulty breathing. Second, the humid and high-temperature environment also increases the chance of biological contamination. A domestic survey shows that 21% of indoor air quality problems are caused by microbial contamination, mainly including bacteria, fungi, pollen, viruses, etc., which may cause respiratory diseases such as allergies and asthma. Again, all types of home appliances and daily activities have increased indoor PM2.5 pollution. The Beijing Municipal Center for Disease Control and Prevention has shown that smoking in the room can increase the PM2.5 value by 12 times. If there are other human activities such as cooking, the concentration of PM2.5 will increase greatly.

Do you know what the air purifier mainly purifies?
The air purifier actually originated from firefighting purposes, but with the development of technology and the frequent outbreak of indoor air pollution, it has gradually become a kind of household air purification equipment! At first, the air purifier belongs to a kind of small household appliances. Under the impetus of smog, it has gradually become familiar and accepted by consumers. This has become a necessity in family life!
So the air purifier can purify those pollutants? First, we must first know what pollutants are in the indoor air. According to the US Environmental Protection Agency, there are about 400 kinds of pollutants in indoor air, but they are roughly divided into Chemical pollutants such as formaldehyde, benzene, TVOC; microbial contaminants such as bacteria, viruses, insects, and particulate pollutants such as dust and pollen.
As a device that can continuously improve the indoor air quality, the air purifier must be able to purify the above three types of pollutants. But in fact, the effect of many air purifiers is far from being achieved! This is because we have a large demand for air purifiers because of smog, so many air purifier manufacturers are purifying them in order to seize consumers. In terms of ability, it tends to move closer to pollutants such as dust and particulate matter.
However, as far as our current indoor air pollution is concerned, chemical pollutants such as formaldehyde, benzene, and TVOC are particularly harmful to us, and it is also the main indoor pollutant at present. The main source is decoration residue. So how does the air purifier clean up the chemical pollutants left by these decorations?
At present, the conventional air purifier on the market is convenient for pollutants such as formaldehyde, and an activated carbon filter is usually used for adsorption. Although activated carbon has a certain ability to adsorb formaldehyde, its drawbacks are also very obvious. According to the research, in ordinary households, the ordinary activated carbon filter will generally be saturated for about 2-3 months, and after saturation, the formaldehyde will be re-emitted into the air, causing secondary pollution. How to solve it, replace the filter!

When moving the suction device, still use this car air purifier?
It is said that air quality determines the quality of life, but it has always been less concerned. The home is using an air purifier, the car has not been installed, the subconscious has an idea: Is that necessary?
It was not until I took the Olans car air purifier to get started testing that I really understood that it was necessary.
There is no air in the emperor here. The most important thing about car air purifiers is to pay attention to these points: Perfect match with the interior Effectively purify the air inside the car Remind you not to smoke in the car (there are related tests below) It seems to be the first car air purifier I reported, and I went straight to the topic. Getting started and installing There aren’t many things in a simple package: a small black air purifier, a cup-shaped battery (for cup holder mounting), and a car power cord.
Get the hand, 0.5 kg weight and delicate skin-like touch will instantly improve the sensitivity. The air outlet is located on the long side of the fuselage, so the machine can be used vertically or flat, but it should not be placed sideways. The interactive interface uses a refreshing LED screen, and in the car, you only see bright white numbers without seeing the background. Since the air purifier does not need many operations, the body has only a simple silver touch button, which can be switched to switch different air volumes.
Allan offers two ways to supply energy, one is to plug in the car power supply for driving (and can also charge the battery). The second is a cup-shaped battery so that you can get off the car and connect it, then set the time switch in the app to ensure that the air has been purified before getting on the bus. In addition to timing, Olans also supports Bluetooth connectivity, allowing you to remotely switch clean, switch air volume, and read air quality index in real-time. If you want to make the most use of this car air purifier, you can – pre-purify with the battery before getting on the car; after the car is connected to the power supply and the battery, while charging and purifying.
After the power is connected, a blue breathing light will be lit around the upper cover of the Oakland. Of course, this is the best air quality, and the red and yellow lights are poorly matched and good. Since the fuselage is mostly black, it is more visually coordinated with the black interior. Alans put a cup-shaped battery on the bottom and put it on the cupholder. It is very stable and visually uncompromising.
Purification effect
(Official nominal efficiency and specifications) General environmental testing – exhaust gas purification in the car. After getting on the bus, the car air purifier was started in the state where the air conditioner and the window were closed. The pollution value suddenly reached more than 100. The fan immediately accelerated, and the air that smelled the air outlet was close to the fresh air. The reading on the LED display dropped very quickly, and in just 5 minutes, it dropped to 5. This time is very satisfying, just to clean the air in a few minutes of the hot car, this process you can monitor the air quality inside the car through the mobile app.
Every time the hot car is at the same time, the air quality is improved to a healthy and comfortable state, and the daily cleaning effect is satisfactory. However, this is only for ordinary people. For the smokers, is this Olans enough? Please see the violent test below: Extreme environmental testing – no ventilation and smoke purification. As with the above test, keeping the windows and air conditioners off, I ordered a cigarette in the car. Just spit out a cigarette, the sensitive Alans responded instantly: I saw the LED screen air quality reading for one-second burst, jumping from 20 to >999, while the breathing light turned red and the fan speed reached the highest. Waiting for Alans to finish the work. In the case of a closed window, the readings in the car can be seen in real-time. In a few minutes, the reading drops quickly:
The biggest feeling is that a few cigarettes have caused pollution to burst for 13 minutes! At 4:13, the smoke smell on the car has become noticeably faded, the fan speed has slowed down significantly, and the breathing light has turned yellow. After 10 minutes, the breathing light gradually turns blue. From the app, the air quality enters. “Excellent” area. After 15 minutes, the air index in the car was purified to 12.
The pollution of the air against the window is really amazing. This test gave me a more intuitive understanding of the impact of smoking. When I saw the reading, I felt that I didn’t want it. Some people may say that I drive in the window, the wind blows away the smoke, and the pollution should not be big? In this regard, let the measured data speak: I carried out a smoking test with the window open while the vehicle was moving. The air quality fluctuated between 300 during the burning process, indicating that the pollution caused by smoking in the window is still not small. Spit the last cigarette and close the window. After 5 minutes, Olaland purifies the air to a level of 80. It turns out that smoking without pollution is just a kind of self-consolation. Because there are various pollutions such as exhaust gas outside the window of the car, the air inside the car will be affected after opening the window. On the other hand, if the fog is encountered, the effect of opening the window is more counterproductive. Therefore, if you want a healthy car air, it is best not to smoke in the car. Some friends can’t help it, it is necessary to go to an Olans.
Good and bad Benefits: good appearance, easy installation, and use, good purification effect, timed purification function The downside: take up the cigarette lighter interface, you have to buy a second or a third cigarette lighter to solve Evaluation: worth buying (for reasons see at the beginning)

The haze is coming again, closing the doors and windows, pretending that the thick smog can’t come in (be strange), as well as the harmful pollution released by interior decoration materials, artificial panels, composite furniture, and the second-hand smoke that floats… These are the pains that can breathe!
“Save the Breath” is a matter of people’s livelihood. Not long ago, Blueair and the Nutshell Network held a DIY Air Purifier Competition. The vast shells were also open-minded and submitted a variety of “empty net solutions”. Let’s take a look at their concept sketches~
[Secondary soul painting] by the stinky gardener
The mobile purifier, based on Hayao Miyazaki’s “Hal’s Moving Castle”, can also fly. Metal detector, 24K infrared laser eye, largemouth strong inhalation, top pipe output, let the bacteria all dogs.
[Please accept your knees] by the peninsula
Installed on the roof, it does not occupy space and is beautiful and elegant, that is, the filter replacement is not convenient. Based on the UFO flying saucer, it has six sides and needs a remote control.
[Future Black Technology] by geeks who love the above art
Stepping on a spinning bike provides a source of power for the machine, both fitness and environmentally friendly. According to the principle of the electrostatic copier, the smog particles are mixed into the ink, and the input text can be printed.
However, only “Alans” successfully entered the three yuan
Acrylic shell + HEPA filter + activated carbon net + fan + power module, from prototype design to DIY production, netizen “-Biu took a big-” took 3 days. She gave this boxy machine a lovely name: Alans. Dubai VS Olansi
So, what is the strength of the new DIY air purifier “Olans”? The shell net came in. Blueair’s most representative Pro L air purifier, in an enclosed glass room with a site of about 15 square meters, held an informal friendly match between the two sides.
Task 1 Spread the board with formaldehyde and then minimize the concentration of formaldehyde in the air within 30 minutes. ▼
Task 2 Simulate the normal indoor environment and then minimize the PM2.5 concentration in the air as much as possible within 30 minutes. ▼
It can be seen from the results of the competition that “Auslanes” has been listed by professional player Blueair “Dubai” in both the formaldehyde project and the PM2.5 project.
Where is the DIY air purifier lost? Is there a problem with the production materials? Or is there a design omission? With these questions, we conducted a comprehensive analysis.
Material selection and process: the foundation laid from the body
▲Production of the acrylic sheet used by Allan
The outer shell of the Australian is acrylic, it has good transparency and plasticity, and most importantly it is cheap. First, cut with a laser, then use a glue gun to bond and seal, the final physical shape looks quite similar…
However, it is just like a model. Industrial grade air purifiers have many features in the selection of materials, processes and product design. Blueair uses solid alloy steel that does not produce harmful substances or cracks like industrial plastics but also has sound and noise resistance.
Blueair’s chief designer, Mr. Magnus, shared his design philosophy: “For Blueair, quality is as important as beauty. Every part is carefully selected and durable. We chose not to use plastic. Rugged galvanized steel, and it doesn’t contain a lot of harmful substances like plastic, you only need to replace the filter to ensure that the product has been used for many years.”
Wind tunnel design: open up the lung capacity, and “do not fight”
▲The fan used in making Alans
The right and top of the Olans enclosure are air inlets and outlets, but after confirmation by Blueair engineers, the air ducts were designed to be oversized and violated safety regulations. The sound control of Olans is also not good. The average noise of 1 minute is 58 decibels, which is close to the loud talk.
The Blueair Pro L uses a right-in and left-out air duct design. In order to expand the contact area with the air, the internal filter screen is also designed as a V-shaped, two filters can be placed at the same time, and there are two correspondingly. The ultra-quiet fans run synchronously and the low-speed running noise is only 29 decibels. A reasonable air duct design not only helps to capture more dirty air but also sends out more clean air, which also helps to reduce “wind noise”.
Filtering: Don’t let the “filter” fight alone
▲Production of the universal filter used by Alans
Olansi uses the common activated carbon particle filter and HEPA filter on the market, but we can clearly see in the PM2.5 test: when the particle content drops to about 60, no matter how many cycles of filtration, the value Can not fall down; and formaldehyde, only purified about 27%.
So is it better to change the denser filter? If the filter is made thick and dense, although the capture rate can be increased, the wind resistance is also increased, eventually, the air volume is insufficient, and the energy consumption and noise are also increased.
How is Blueair solved? Blueair uses an ultra-quiet patented technology, HEPASilent®, which combines electrostatic and mechanical filtration to deliver more clean air with minimal energy consumption and noise. All products are certified to “zero ozone” by ARB testing. Without any harmful emissions.
For gaseous pollutants such as formaldehyde, Blueair has developed a new activated carbon filter: the honeycomb structure is removed, the wind resistance is smaller, and the contact surface is more sufficient; the alumina carrier with better activity is used, the microporous structure is more developed; the cold catalyst content is increased by 3 times. Capturing formaldehyde is more powerful. After a new upgrade, the Blueair filter has reached the highest national CCM level and can capture more air pollutants at the same time.
CADR: Race against time
An important indicator for choosing an air purifier is CADR, which is simply the volume of air purified per unit of time. Indoor air is flowing dynamically. Ingress, cleaning, ventilation, and walking will increase the number of impurities in the air. If the CADR is not high enough, the purification speed will not keep up with the continuous generation of pollution.
In fact, through the test results, we can see that the CADR of Aol’s is much lower than that of Blueair, but how strong is the CDAR value of the Blueair Pro L up to 700m3/h?
In a 45-square-meter meeting room, the shell network tested the performance of the Blueair Pro L: after 90 minutes, the concentration of PM2.5 in this room dropped from 128μg/m3 to below 5.84μg/m3… And this is not the limit, the Blueair Pro L can be used for up to 84 square meters of space.
Detection: not let go of every corner
The actual use of the air purifier is very important. We open the air purifier every day. Is the indoor air really getting better?
In order to detect the actual effect of the air purifier, it is not enough to measure the data of the tuyere. The air purifier will first purify the nearby air, but the indoor air is always flowing, and people will walk around every corner of the room, so the correct method should be to measure every corner of the room. When the entire room was cleaned, the air purifier really worked.
Professional instruments are also indispensable during the testing process. In order to solve the problem of expensive instruments, Blueair provides users with free on-site air detection services. Experienced inspectors will never let go of any corners. Finally, detailed inspection reports will be issued, and the actual use of the products will be clear at a glance.
Technology: Serving a better life
The technology stems from a curiosity about the unknown, and the exploration of the limits, Blueair engineers prefer to use technology to make life better. By comparing with the DIY air purifier, we found that in order to truly master the technology and produce excellent products, professional knowledge and dedication are indispensable.
The Smart Age has been launched, and Blueair has also launched the smart app Blueair Friend and the smart detection product Blueair Aware and recently launched the live view Air View by Blueair. Air View, like Google Earth, contains 360° real-life photos of major cities around the world. The data is updated daily in real-time, and China is also planning to include it in the future.

You may never have thought of this toxic substance in an air purifier.
Under the smog, many families have purchased air purifiers, hoping to bring a small environment for families, especially the elderly and children, to breathe safely.
As the PM index on the air purifier continues to drop, you will feel a little comfort in your heart. Many people regard the air purifier as their last respiratory guardian.
But the following news may cause you to have doubts about the air purifier in your home.
Metal texture dividing line
On July 20 this year, the Ministry of the Environment of the Republic of Korea broke out that OIT (octylisothiazolinone), which is harmful to the human body, was detected in the air purifiers and air-conditioning filters on the Korean market. OIT-containing products cover most of the brands on the market, with up to 84 models.
What is OIT? OIT is an antibacterial, mildew-resistant, oil-soluble chemical. On some filter screens marked with “sterilization” type purifiers, manufacturers use OIT, an anti-fungal agent to sterilize and prevent the strainer from becoming moldy. However, this chemical is harmful to the human body, it is highly toxic to aquatic organisms, and causes an allergic reaction in the human body in direct contact or through the air. The anti-mold agent component enters the human body together with the exhaust of the purifier and the air conditioner.
The Korean Ministry of the Environment has conducted a risk assessment and believes that OIT, an antimicrobial ingredient, poses a potential risk to human health. For public health reasons, the Korean Ministry of the Environment has asked major manufacturers to recall all air purifier filters containing OIT components.
According to a report by South Korea’s International Broadcasting Station (KBS) on July 22, the list of 84 air purifiers and air conditioners containing the toxic substance OIT announced by the Ministry of Environment of the Republic of Korea, some of Samsung Electronics, LG Electronics, Cuckoo, and other companies. The product is impressively listed.
The filters of these companies are produced by two international brands.
Subsequently, 3M apologized for the detection of toxic substances in the air purifier filter and immediately began recalling the product.
Metal texture dividing line
So, is the current domestic purifier brand concerned about OIT?
Taking science home to investigate the current air purifier products in China, we found that with the exception of a few products, most brands did not explicitly indicate that they did not contain OIT ingredients in the product description.

Analysis of the trend of future indoor air purifier design
In recent years, with the improvement of living standards and the intensification of air pollution problems, people are paying more and more attention to the quality of indoor air. Therefore, indoor air purifiers have also received more extensive attention, and many high-quality air purifier products have appeared on the market.

Sensor observation: research on new trends in domestic air purifier market
At present, with the continuous promotion of formaldehyde removal products and the increase in demand for new housing, air purifier products with formaldehyde screen display will further increase. At present, in the aspect of formaldehyde detection, the mainstream sensor application is an electrochemical sensor, and the mainstream application of dust detection is a laser particle sensor. Other detection contents include VOC correlation, temperature, humidity, and the like. Below, please follow the sensor expert network Xiaobian to understand the new trends of the current air purifier products, as well as the application of sensor technology.
In the case of air purifiers in addition to formaldehyde, the mainstream sensor application is electrochemical sensors. Air purifier store, data map
In addition to formaldehyde function into a new hot spot in the air purifier market
With the improvement of China’s air quality, sales of domestic air purifiers have fallen sharply in recent years, and the industry’s prosperity has shrunk. At the same time, after experiencing explosive growth, the air purifier market as a whole began to return to rationality, which also increased sales pressure in the market. So, what is the performance of the current air purifier products?
At present, in the market, manufacturers are more focused on the promotion of formaldehyde removal. In the product identification, most products no longer use PM2.5 as the main identification object but focus on the removal of formaldehyde. In addition, in the promotion of product features, it has become more detailed and diverse. For example, at present, Super air purification products mainly use the new house to eliminate formaldehyde demand as the main promotion group, equipped with French NanoCaptur formaldehyde decomposition technology to rapidly decompose formaldehyde.
However, there are many purifier products with formaldehyde removal function on the market. But in terms of effect, there are still some differences in different products. At present, in addition to formaldehyde, there are two ways of simply adsorbing formaldehyde and decomposing formaldehyde. In contrast, products using the decomposition of formaldehyde technology are relatively more expensive.
In promoting the function of removing formaldehyde, Samsung and Yadu are also prominent. In addition to formaldehyde-enhanced products, Samsung has used two independent sensors for PM2.5 detection and odor detection to more accurately detect air quality. It is understood that the price of Samsung’s enhanced formaldehyde-removal products is currently concentrated at 2,000 to 8,000 yuan, and some products have a child lock function. At present, most of A.O. Smith’s products are equipped with formaldehyde numerical display function, and the price is concentrated at 4,000 to 10,000 yuan.
Say goodbye to the previous focus on firepower promotion in addition to PM2.5 capabilities, including virus H1N1, formaldehyde, pollen, soot, etc., have become the main selling point of air purifier products. At the same time, many products have posted various certification marks such as Chinese patent products, China environmental protection products, and AHAM.

Homogenization is still the new air purification robot eye-catching
However, homogenization remains a major problem in air purification products. At present, the air purifier products on the market are mainly white and gold and the difference in appearance is not large. In terms of the air outlet, the air is vented on the two sides of the wind is driven in and out. A few products are windy on the wind.
In addition, in some air purification product stores, new air purification robots have emerged, and they are quite intelligent. These robots break the problems of traditional air purifier purification source fixation, limited purification range, low purification efficiency, etc., and are equipped with high-precision infrared ranging sensors, ultrasonic obstacle avoidance sensors, down-sight anti-drop sensors, dust sensors, and other up to 40 sensors. Breaking through the room restrictions, the robot intelligent mobile platform is combined with air purification technology to meet the multi-room purification needs.
In general, in the context of the intelligent development of electrical products, the intelligent trend of air purifier products is constantly improving. Currently, most air purifiers have Wi-Fi control and mobile APP control and smart sensing. In the future, intelligent upgrades will be the trend in the field of air purifiers. Correspondingly, sensor manufacturers can also find favorable business opportunities. At the same time, in the future, Sensor Expert Network will continue to pay attention to the domestic air purifier market and new trends in sensor applications, so stay tuned.
