Seven Misunderstandings about Air Purifiers Improper use can cause secondary pollution

Seven Misunderstandings about Air Purifiers Improper use can cause secondary pollution

best air purifier,air washer,intelligent air purifier

Winter smog frequently erupts, and there are a lot of harmful substances such as sulfur dioxide, nitrogen oxides and heavy metals in the smog, which is extremely harmful to human health, especially for the elderly and children with poor resistance. At the same time, indoor air pollution problems such as interior decoration and cooking have existed for a long time, and many households have adopted air purifiers as a standard for quality life. But as long as you buy an air purifier, would you? In fact, many consumers have different levels of misunderstanding in the use of air purifiers, and some misunderstandings may even bring secondary pollution. Let’s talk to you about the misunderstandings of air purifiers.

Misunderstanding one

No matter how big the house is, one is enough.

Due to the lack of understanding of the air purifier, some people think that it is enough to have a small air purifier in the house. In fact, the air purifier has a corresponding applicable area, which is similar to the air conditioner, except that the air conditioner is different in size for different sizes of rooms.

Some air purifiers on the market have clearly marked applicable areas. If not marked, the purifying area of ​​the air purifier can also be calculated from the CADR value (clean air volume) of the product: applicable area = CADR* (0.07) ~0.12), the corresponding CADR value can be calculated for the actual purification area, and then the consumer can select the air purifier product. In general, large-sized rooms may be considered to have a corresponding air purifier in the number of rooms.

Misunderstanding two

Put a humidifier next to the purifier

After many friends have purchased an air purifier at home, they will also purchase a humidifier to avoid the winter room being too dry. When using the air purifier, turn on the humidifier at the same time. In fact, it has been found that if the humidifier is placed next to the air purifier, the indicator light of the purifier will be alarmed, and the air quality index will rise rapidly. It seems that the two will interfere with each other.

In fact, this is because the water added to the humidifier is not pure water, but tap water. Because tap water contains more minerals and impurities, chlorine molecules and microorganisms in the water may be blown into the air with the mist sprayed from the humidifier. Form a source of pollution. If the tap water has a high hardness, the water mist may have white powder, which may also pollute the indoor air. Therefore, it is recommended that if you need to turn on the humidifier and air purifier at the same time, be sure to leave enough distance.

Misunderstanding three

Air purifier is close to people

When the air purifier is working, due to its working principle, the harmful gases around the air purifier are actually more. Therefore, do not place it too close to people, but also should be properly raised to avoid contact with children.

Moreover, an air purifier such as an electrostatic adsorption type can cause pollutants in the air to be adsorbed on the electrode plate during operation. However, if the design is not reasonable enough, a small amount of ozone will be released, and more than a certain amount will stimulate the respiratory system. When using this air purifier, it is best not to stay in the room, and to close it after entering the house, because ozone can be quickly restored in space and will not remain for a long time.

Misunderstanding four

Do not change the filter for a long time

Many people in the process of using air purifiers often ignore the life cycle of the air purifier filter and use cleaning. Since the filter has a certain degree of saturation, during the operation of the air purifier, the purification function will gradually decrease as the adsorbate increases. Moreover, after the filter is saturated, the particles adsorbed on the filter will become a hotbed of virus pathogens, which will multiply and breed bacteria. If it is not replaced for a long time, it will not only purify the effect but will release harmful substances. “Pollution source”, causing secondary pollution.

However, many brands of air purifiers on the market now have smart reminders to replace the filter screen and clean the reminder function, and must be replaced in time when it needs to be replaced. However, the cleanable filter screen like the primary filter screen is recommended to be cleaned regularly. After all, the purification effect will be worse after a large amount of adsorbent, and the life of the rear filter net will be reduced to some extent.

Misunderstanding five

Haze genius needs to use air purifier

The hot sale of air purifiers is mainly caused by the continuous haze weather, but not only the haze is pollution. In fact, in many cases, indoor air pollution is far more terrible than smog. As early as 2011, the World Health Organization pointed out that indoor air is 5-10 times higher than outdoor air pollution. For example, bacteria, viruses, pollen, dust, odor, bacteria, chemical gases, etc. suspended in the air can cause adverse effects on the human body and even seriously threaten human health. In particular, new homes that have just been renovated are even more harmful to vulnerable people such as the elderly and children with poor resistance.

Of course, if the outdoor air is good, it is recommended that the room be ventilated and ventilated, and maintain a certain humidity so that fresh air can flow indoors. Sometimes this effect is more effective than opening an air purifier all year round.

Misunderstanding six

No smell in the room means the air is very clean.

The indoor air standard is a comprehensive measure of the content of inhalable particulate matter, harmful gases, odors and bacterial viruses. It is unreasonable to determine the air quality by odor alone. In addition to the large particles and odors that are easily felt on the surface, formaldehyde, benzene, radioactive cesium and other undesirable gases are colorless and odorless, and will only be revealed by the detection of air purifiers. These bad gases will cause great damage to the body. hurt.

Misunderstanding seven

Purify for a while

Some consumers will feel that it is very expensive to open the air purifier for a long time. In order to save electricity or think that the purification can achieve the effect for a certain period of time, it will be turned off after a certain period of work. In fact, the air purifier itself does not consume much electricity. It belongs to power-saving small household appliances. At present, the air purifiers with good quality have intelligent mode and power-saving processing mechanism. When the air is detected, the air purifier will start running at a low speed. If you start to smoke while sitting on the side, it will automatically run quickly, and then resume the smart mode after reaching the standard.

Moreover, the most important thing is that the PM2.5 concentration in the indoor space will gradually increase after the air is up to standard, and the PM2.5 will continue to enter through even closed doors and windows. Therefore, it is usually good to continue to purify the effect, especially when the haze is serious.

To sum up

In the current smog in the smog, the use of air purifiers has long been a necessary measure to effectively protect the health of the family. However, only by avoiding misunderstandings and scientific use of air purifiers can we improve indoor air quality more quickly and effectively, and truly enjoy healthy air.

Air purifier principle

Air purifier principle

Although our economy has developed rapidly, as the pollution has become more serious, our air has been greatly affected, so it may become difficult to have fresh and clean air, so this is the point. In terms of life, air purifiers are very important.

air purifier
Air purifier, also known as “air cleaner”, is a product that can adsorb, decompose or convert various air pollutants and effectively improve air cleanliness. It has the functions of regulating temperature, automatically detecting smoke, filtering dust, eliminating odor and harmful. Gas, double sterilization, release of negative ions and other functions, currently used to clean indoor air pollution domestic and commercial air purifiers; it is a micro-fan (also known as a fan) inside the machine to circulate indoor air, polluted air through After the air filter in the machine (two times of filtration), various pollutants are removed or adsorbed, and then the air is continuously ionized by a negative ion generator installed in the air outlet (the high voltage generated in the negative ion generator during operation generates a DC negative high voltage). A large number of negative ions are generated and sent by a micro fan to form a negative ion airflow to clean and purify the air, thereby providing a “microclimate environment” similar to fresh air in nature.
Air purifier principle

air purifier
Although the working principle of the air purifier is different in name, type, brand, and function, it traces back to the root cause. From the working principle of the air purifier, it is mainly divided into two categories:

The first category: passive adsorption filter air purification principle
The passive air purifier uses a fan to pump air into the machine and filters the air through the built-in filter to filter dust, odor, and disinfection. This type of filter-type air purifier uses HEPA filter + activated carbon filter + photocatalyst (cold catalyst, multi-catalyst) + ultraviolet disinfection + electrostatic adsorption filter to process air. The HEPA filter has filter dust particles. The role of other activated carbons is mainly to absorb odors. Therefore, it can be seen that there are various types of labels on the market with fan filters, photocatalysts, ultraviolet rays, static electricity, and the seemingly chaotic best air purifiers. The principle is basically the same, both passive adsorption filter air purification.

The second category: active air purification principle
Dual purification air purifiers and active air purifiers on the market and generally only one active purification technology. At present, there are mainly silver ion purification technology, negative ion technology, low-temperature plasma technology, photocatalytic technology, and plasma ion group technology. The fundamental difference between the active air purification principle and the passive air purification principle is that the active hot sale air purifier is free from the limitations of the fan and the filter screen, and is not passively waiting for the indoor air to be pumped into the purifier for filtration and purification, and then It is discharged through the fan, but it effectively and actively releases the purification and sterilization factor into the air. Through the diffuse nature of the air, it can reach the corners of the room and purify the air without dead angle. At present, the more active purification technology in the technology mainly uses negative oxygen ions as a purification factor to treat air and ozone as a purification factor to treat air. These two are typical air purifiers that work based on the principle of active purification.
Air purifier

air purifier
Air purifiers are useful for us to purify the air. The four points of the air purifier are described below.

1, can decompose volatile organic compounds:
It can effectively decompose harmful chemicals such as benzene, formaldehyde, and VOC (harmful volatile organic compounds);

2, can eliminate odor:
It can effectively eliminate the odor of decoration, irritating odor through human body breathing, sweat, mildew, rot and so on;

3, can settle the inhalable particles:
It can settle respirable suspended particulates such as dust, smoke, dander, solid carbides, and ions generated at the same time can eliminate particulate matter (PM2.5) in the air.

4, can effectively kill harmful microorganisms:
It can kill pathogenic microorganisms such as bacteria, mold, Legionella, hepatitis virus, influenza virus, avian influenza virus, SARS virus, etc., and common in the air (range: 0.01 to 10 microns).
How to use the air purifier

air purifier
Proper use is also very important for the life of the air purifier and the effectiveness of its use.

1. Always turn on the air purifier to clean the air at home. It works best with the air conditioner. Use the time switch when leaving the room.
2. When the cleaning signal light is on, it indicates that the dust collection is full, and the dust collecting plate should be cleaned.
3, the purifier should be placed in a dry and ventilated place, 15 square meters of room, boot 2 hours a day.
4. When using air purifiers to treat respiratory diseases, it should be carried out under the guidance of a doctor.
5. When the air purifier is energized, direct contact should be avoided because the voltage is high to prevent electric shock. When breathing as a disease, it should be more than 0.3 meters from the outlet.
6. When the purifier is not in use, unplug the power plug and do not turn it on to prevent accidents.

The world’s largest air cleaner inhales smoke and turns it into jewelry

The world’s largest air cleaner inhales smoke and turns it into jewelry

The air we breathe is not as clean as it used to be – often worse.

According to recent statistics from the Lung Association, about four out of ten people in the United States live in counties with low levels of ozone or particulate pollution.

Dutch designer Daan Roosegaarde has developed a 7-foot (23-foot) high air purifier, the Smoke-Free Tower, to clean the air and increase its permeability again.

Tower devices absorb smoke, basically like a vacuum from the top, and exhaust filtered air through six vents, which can clean more than 30,000 cubic meters of air per hour.

The Kickstarter-funded project has allowed Roosegaarde to conduct research and development for about three years, but this week he showed his prototype of a giant air purifier based on the park on Roosegaarde’s website in Rotterdam.

Roosegaarde explains how it works on Tower’s Kickstarter page.

“By charging the smokeless tower with a small positive current, the electrodes feed the positive ions into the air. These ions adhere to fine dust particles.

A negatively charged surface, the reverse electrode, attracts positive ions with particulate dust, but particulate dust that usually harms us is collected by ions and stored in the tower. Capturing ultra-fine particles of smoke that can not be achieved by the traditional filtration system. ”

However, carefully designed air purifiers can be used not only to clean smoke but also to make high-quality jewelry.

Tower Smoke 2 Studio Loose Guard

The tower can condense the tiny carbon particles it collects to form small “jewelry” that can be embedded in gems such as rings and cufflinks, each representing 1000 cubic meters of air.

Although the prototype is currently in Rotterdam, Roosegaarde will eventually deploy other models in Beijing, Mexico City, Paris, and Los Angeles.

Jokes and Air Purifiers: Beijing People’s Life in the Smoke Period

Jokes and Air Purifiers: Beijing People’s Life in the Smoke Period

The suffocating smog from Monday to Beijing and many of the country’s more serious conditions have triggered such a smart crack by social media users in catastrophic circumstances.

In the past few days, jokes on this topic have become one of the most discussed topics on Sina Weibo, China’s largest microblogging website.

However, despite a casual attitude towards the harmful atmosphere, residents of the capital have felt the impact of one of the smokiest games in Beijing since July.

The National Meteorological Center (NMC) upgraded its yellow warning on Tuesday afternoon to the second tallest orange on Thursday afternoon.

She came home with urticaria for five months, but blood tests showed that she was allergic to substances in the air.

“When I traveled outside Beijing, my symptoms were relieved,” she said, but the rash had worsened in the past two days.

At Guang’anmen Hospital, a doctor told her that her symptoms were affected by smoke.

An unknown staff member of Beijing Children’s Hospital told Xinhua that they had not seen a significant increase in the number of patients preparing for the peak respiratory problems because the smoke had just begun.

“Every time smoke continues, more students ask to be ill,” said Professor Wang Xia, 34. ”

Beijing’s environmental monitoring agency suspects that farmers have accused burning straw fields of causing smog, and Beijing suspects that.

However, Li Lixin, an air pollution control officer of the Beijing Environmental Protection Bureau, conducted satellite tests in the summer of 2013, and amplified fire discharges were used to measure PM 2.5 readings of 110 to 460 microns in Beijing. A few hours later, it showed that it could pull up to gram/cubic meter.

However, Internet users question prices.

“Agriculture has become an important industry in China for hundreds of years, even hundreds of thousands of years. After harvesting in autumn, farmland harvests straw and ashes as fertilizers. “It’s a tradition,” said Weibo users, nicknamed Sunflower, “but why didn’t smoke in the past?”

In response to such criticism, Wang Yu, who is in charge of Beijing’s energy ecosystem, said that pollutants mainly come not from burning straw, but from automobile exhaust, coal combustion, industrial production, and dust. I admit it.

“But this is the season for burning straw, which is consistent with the special climate of high humidity and windless. It’s like straw breaking a camel’s back and causing air pollution, “he said. I have told you.

It is not the only smoke control measure to ban firewood cutting in Beijing and its surrounding areas.

In addition to banning straw, the city has promised to replace coal with cleaner-burning energy, such as household electricity and natural gas, coal sales and use by the end of 2020, and other highly polluting fuels. I want to suppress fuel oil, petroleum coke, combustible waste, biomass fuels, etc.

Beijing also levied fees on major pollutants such as sulfur dioxide and nitrogen oxides this year.

Li Lixin said it may take some time to see the results of such a measure, but the government believes that the issue is very important and people’s awareness of environmental protection has improved.

Meanwhile, Beijingers shunned outdoor activities and excluded thousands of people from indoor protection.

An anonymous old man named Chen said that his friends with asthma and bronchitis would remind them not to go out in the smoke.

Wang Xia’s school has stopped carrying out outdoor activities for students. “What if we can install every classroom,” she said.

Sales of air purifiers have almost doubled in the past two days, according to Zhang, a sales representative for the e-commerce platform Jingdong Electronic Brand SHARP.

“I bought this for her because my granddaughter is very young,” she said. Well, I hope it will clear up soon. ”

New Air Purifier Standard

New Air Purifier Standard

On Friday, authorities announced new national standards for air purifiers and placed orders in the country’s chaotic purifier market.

China said the draft national standard will be released on Friday and will include more specific indicators to measure the performance of air purifiers, including “clean air supply rate” and durability. It’s reported every Saturday.

According to reports, the country’s widespread air pollution problem is getting worse and worse. The market for air purifiers is growing rapidly, with a total sales of 2.4 million in 2013.

However, according to media reports, the market is chaotic, and many air purifier manufacturers and sellers exaggerate product performance and deliberately mislead consumers.

According to the report, according to the spot check of 20 air purifiers by Shanghai Municipal Air Quality Technical Supervision Bureau, only 3 products show advertising effects and effective workspace.

The new draft sets out detailed requirements for air purifier display. The manufacturer must clearly indicate on the product label the service life and volume of space that it can provide effective filtering.

The draft specification contains performance data for particles and formaldehyde.

According to the report, the National Center for Quality Control of Indoor Environment and Indoor Environment Products, which was established in 2002 and revised in 2008, failed to meet public expectations. Director of Song Guangsheng.

“Previous national standards for indoor air purifiers did not take into account the need for consumers to filter PM2.5 or the increased frequency of use,” he said.

PM2.5 is a kind of particle with a diameter of fewer than 2.5 microns, which is an important index of air pollution in China. The high density of PM2.5 is the main cause of the black smoke in many parts of the country in recent years.

Beijing has the world’s largest air purifier to fight smog

Beijing has the world’s largest air purifier to fight smog

A heavily polluted fire has attacked the city, taking people into their rooms, and plans to deploy the world’s largest outdoor air purifier, designed by Dutch engineers, in the smoggy capital of Beijing. The last-minute inspection of Beijing 751 D Park Art Zone will be held shortly after the release of Daan Roosegaarde, and tours will be held throughout the country. Non-governmental organizations and Environmental Journalists from the Ministry of Environmental Protection of China.

The tower can capture about 75% of the small particles around PM2.5 and PM10, then release clean air and create “bubbles” of fresh air around it. Since the beginning of October, ozone-free ion technology has been plagued by serious smog in Beijing. The city’s environmental protection department issued a “yellow warning” on air pollution on Tuesday.

“Yellow warning” is the third most serious level in the four-level color-code warning system, red is the most serious, orange is the second most serious, and blue is the most serious pollution level.

Even if the cold front clears the smoke in the morning, the average PM2.5 density of today’s lethally polluted particles is over 300. They urged people to gather together to fight the smog.

Every day, he said, the people, blood and others were troubled by the operation of the tower and asked the authorities to contain dangerous sources of pollution.

“The so-called sacred smoke cleaner is like a performing art, and there is little difference in cleaning urban air. It wastes polluted air and exhales the fresh air, but only a few. The air will continue to be polluted, “Sina Weibo users’comments are quoted every day.

How Air Purifier Reduces Allergies

Have you ever considered an allergic air purifier? Does your head feel exploited, your eyes watering, your nose running, are you itching? Do you want to feel yourself again? Maybe it’s time to consider air purifiers.

Why is it allergic to use an air purifier?

The use of air purifiers can provide long-term treatment and reduce the cost of allergy treatment. According to the Centers for Disease Control and Prevention, 13.1 million doctors are admitted every year because of allergies. The common triggers for allergies are seasonal triggers, such as dust, mold, pets, and pollen.

Allergies are just your body’s overreaction to foreign bodies. Air purifiers can greatly reduce the number of allergens in the home by solving source problems.
