What air pollutants can air purifiers absorb

Walking into modern homes, we can find that in addition to traditional home appliances such as empty ice washers, home appliances that improve the quality of life such as sweeping robots and air purifiers have also begun to enter thousands of homes. In addition to meeting the needs of daily life, a better quality of life has also become what modern people are seeking. In fact, everyone is no stranger to the product of air purifier. As long as the term PM2.5 was known to everyone, air purifiers entered people’s sight. And as to whether the air purifier is useful or not? Can the air purifier absorb formaldehyde? Such questions also exist. What kind of air pollutants can air purifiers absorb? Working principle of air purifier,Today, let’s talk about this.

 

PM2.5

 

PM2.5 has an important impact on air quality and visibility. Compared with the coarser atmospheric particulate matter, PM2.5 has a small particle size, large area, strong activity, easy to carry heavy metals, microorganisms and other harmful substances, and has a long residence time in the atmosphere and a long transportation distance, which is harmful to the quality of the atmospheric environment and the human body. There is a certain threat to health. PM2.5 is not only available outdoors, but also indoors. Ninety percent of indoor PM2.5 comes from smoking, and the cooking fume produced by cooking will also aggravate the indoor concentration of PM2.5. Due to the particulate matter produced by smoking and cooking oil fume, long-term exposure may cause damage to the human respiratory tract.

 

formaldehyde

 

Formaldehyde is a colorless irritant gas, which has irritating effects on human eyes and nose. At present, formaldehyde has been listed as a “known human carcinogen”. The biggest factor that causes excessive formaldehyde in the indoor environment is home improvement building materials. In home improvement building materials, formaldehyde hides in various glues and coatings in wall paint, floor, and furniture. Formaldehyde can cause tension, dizziness, headaches and other hazards to the nervous system. It can also damage the respiratory tract, digestive tract, circulatory system and nervous system to varying degrees. Long-term living in a house with excessive formaldehyde may cause serious consequences.

 

Dust, bacteria and other substances

 

Indoor dust, shedding hair, pet dander, indoor odor, bacteria and viruses and other indoor pollution particles can easily pass through the human hair filter and blood barrier, causing discomfort and disease to humans. Diseases such as allergic asthma, family colds, and other respiratory infections may be closely related to the poor quality of indoor air. Indoor air pollution seriously affects our health every day.

 

Air purifier mainly uses a fan to draw air into the machine, and then filters the air through a built-in filter, which can filter dust, odor, and disinfect. Generally speaking, air purifiers are suitable for newly renovated or renovated homes, homes with asthma or pets, hotels and hospitals and other public places.

Why do we need to buy an air purifier for indoor air purify?

As we all know, air purifiers are not only used at home, but also in medical, industrial and other fields. The main function of air purifiers is to remove particulate matter in the air, and can also solve problems caused by decoration or other reasons. Indoor and car volatile organic matter air pollution problems. Because the release of air pollutants in these relatively closed spaces is characterized by persistence and uncertainty, the use of air purifiers to purify the air is one of the recognized methods to improve indoor air quality. So, what air pollutants can air purifiers purify? Let’s briefly share them below.

  1. Formaldehyde, Benzene

 

In recent years, it can be seen in many news that many children or adults have been attacked by formaldehyde because they live in newly renovated houses, but they have not dealt with formaldehyde properly, and finally get “acute leukemia”. It can be seen that formaldehyde has become the largest source of indoor pollution due to some inferior decoration materials and the failure to properly handle the house after decoration. Many formaldehyde raw materials will be attached to wardrobes, floors, and paints, and this is a long-term volatilization process. In addition, harmful pollutants such as benzene are also high pollutants that are harmful to human health.

 

  1. “Second-hand smoke”

 

There are more than 1.3 billion people in the world who smoke, which also causes many people to inevitably inhale “second-hand smoke”, and “second-hand smoke” is also the second largest source of indoor pollution. “Secondhand smoke” will release more than 7,000 kinds of chemical substances, of which more than 250 kinds are harmful to human health, and there are 93 kinds of carcinogens and harmful substances. In addition to the possible induction of lung cancer, it may also cause malignant diseases including oral cancer, laryngeal cancer, stomach cancer, liver cancer, etc. In addition, respiratory diseases such as asthma and chronic obstructive pulmonary disease, and cardiovascular and cerebrovascular diseases such as coronary heart disease and stroke may also be induced. Moreover, “second-hand smoke” is more harmful to children’s health.

  1. Air pollution

 

In the past few years, smog weather has been reported constantly, and even the most exaggerated is that people cannot be seen within ten meters. The haze is mainly composed of sulfur dioxide, nitrogen oxides and inhalable particulate matter, and its impact on the respiratory system can cause acute rhinitis and acute bronchitis; it will also lead to the weakening of near-surface ultraviolet rays, making the infectious bacteria in the air. The activity of the disease is enhanced, and the number of infectious diseases increases; it has a certain impact on traffic safety, and it is easy to cause traffic jams and traffic accidents.

 

  1. Allergy to pollen

 

Every year from March to June, it is the high incidence period of pollen allergy. Many people with allergy to pollen have symptoms such as sneezing, runny nose, watery eyes, nasal congestion, etc. However, the allergic phenomenon of users is not serious. Pollen allergy occurs in all age stages from newborn to middle-aged and elderly. There is no obvious gender characteristic, but there are significant hereditary characteristics. Moreover, with the current medical technology, pollen allergy cannot be completely cured, and it is easy to recur, and more emphasis is placed on prevention.

  1. Dust mites

 

Not many people may have heard of the word dust mites. Dust mites belong to the family Acaridae and a micro-organism of the genus Dust mites. The main species related to human allergic diseases are house dust mites, dust mites and burial mites. Eurasian mites, etc. Dust mites are an important allergen that induces bronchial asthma, and the common clinical manifestations of dust mite allergy are asthma and allergic rhinitis.

 

These five pollution sources can be restrained by current air purifiers, which is the value of consumers buying air purifiers.

Heavy air pollution hits, and the air purifier market reappears

Affected by unfavorable weather, many parts of northern my country have encountered severely polluted weather. As of November 4, 2021, 20 cities in the eastern region have activated orange warnings for heavy pollution weather, and 9 cities have activated yellow warnings. At 16:00 on November 4, the Beijing Heavy Air Pollution Emergency Headquarters Office launched a yellow warning for heavy air pollution, and Beijing’s air pollution gradually increased, reaching level 5 severe pollution.

In the face of severely polluted weather, consumers have started to panic buying air purifiers. According to data from JD Home Appliances, compared with the average daily sales in October, the sales of air purifiers in Beijing on November 4 increased by 73% month-on-month, doubling the national growth rate. As people pay more attention to indicators such as air quality and PM2.5, air purifier products have also become popular in the domestic market and have entered a period of hot sales.

In severely polluted weather, the components in the air will also become complicated. Pollutants such as PM2.5 particulate matter, allergens, dust, etc., are suspended in the air for a long time, and even contaminated on people’s clothing and brought into the home. In haze weather, opening windows for ventilation will allow dirty air to enter the room. Therefore, the closed doors and windows prevent the air from circulating. In addition, the particulate pollutants carried in by people coming back from the outdoors will make the indoor air. The deterioration of quality always threatens people’s physical and mental health.

Such an environment gives the air purifier a chance to show its talents. Turning on the air purifier can not only deal with particulate matter in the air, but also deal with some allergens, cigarette smoke, formaldehyde, and even some germs, effectively improving air quality. In the most common years of haze weather, air purifiers have always been a hot-selling category in home appliances, and once became the “standard equipment” in many people’s homes.

It is reported that air purifiers have a higher penetration rate in Western developed countries. The household penetration rate in the United States is 27%, and the penetration rates in Canada, Italy, Japan and other countries are all above 20%. At present, the penetration rate of air purifiers in my country is lesvss than 1%, and there is huge room for improvement in the number of air purifiers.

With the rapid development of the market, problems such as uneven quality of air purifiers, inconsistent standards, and false functional standards frequently appear. After the implementation of the new national standard, the competitive landscape of the air purifier market has also quietly changed. On the one hand, products with substandard quality are quickly eliminated; on the other hand, in addition to the basic functions of haze and formaldehyde, consumers have gradually deepened their understanding of odor removal, bacteria removal, and pollen removal, and the trend of product upgrades has become more obvious. In a market with many brands, how to choose an air purifier that meets their needs has become a common concern for consumers.

 

Olansif air purifier subverts the traditional air purification model through the indoor air health management system. It is the first to rely on three-dimensional multi-dimensional space on the roof, floor and wall, and adopts new technologies, new materials and new processes to achieve direct decomposition of formaldehyde, efficient sterilization and inactivation And other functions. No need to replace consumables, no secondary pollution, save money, effort, and worry, providing consumers with a cost-effective air purification solution.

After reading this article, you can also be an air purifier expert!

In the blink of an eye, the consumer rights protection day of the new year will come again. To this end, we are preparing the Special Planning] series, hoping to make more people have a clearer understanding of the purification industry (including standards and brands).

With the deteriorating atmospheric environment, air purifiers have gradually entered the home and become a necessities of the home after refrigerators, TVs, and air conditioners. Unlike other home appliance industries, as a newly emerging industry, the air purification industry is relatively chaotic due to the lack of comprehensive and systematic industry standards, and all kinds of chaos are full of chaos: shoddy, exaggerated functions, and price hikes. Under all sorts of chaos, the most severely damaged rights are consumers.

Olansi Product range-new

In order to protect the legitimate rights and interests of consumers and to further regulate the market, the first mandatory standard for the air purification industry came into effect in March last year. Since the Ministry’s standard came into effect, many consumers have regarded it as a life-saving straw to “beware of being trapped”, while many businesses have regarded it as an important weapon to “capture a larger market.” In order to facilitate the memorization, some people have specially refined its essence, the so-called “three highs and one low”. However, just grasping the “three highs and one low” can you guarantee that you are buying reliable and suitable products? This may not necessarily be the case.

As the first mandatory standard in the purification industry, the national standard  “Air Purifier” proposes four core performance indicators, namely CADR (clean air output), CCM (cumulative purification volume), purification energy efficiency, and noise. The so-called three highs and one low are high CADR, high CCM, high purification energy efficiency and low noise. But this formulation is simple but not precise.

CADR (Clean Air Volume), expressed in cubic meters of air that can be purified per unit time, directly reflects the actual working capacity of the purifier. The larger the CADR value, the stronger the purification ability. But it does not mean that the larger the CADR value, the better. The CADR value should be selected reasonably according to the indoor living area, so as to avoid the unsatisfactory purification effect caused by the “small horse-drawn cart” or the waste of electricity caused by the “large horse-drawn cart”. In addition to the excessive consumption of electricity, some purifiers that can emit ions also release too much ions, which affects the health of family members.

K15C

How to choose the appropriate CADR according to the size of the room, here is a judgment basis: (0.07~0.12)*CADR=usable area.

Regarding CADR, you need to pay special attention: CADR is divided into CADR for particulate matter and CADR for harmful gases. The values ​​of the two are usually different. The CADR value of particulate matter will be larger than the CADR value of harmful gases.

In addition, for a small fixed space such as a car, the CADR value will not reflect the purification effect more directly and accurately than the purification efficiency. The CADR value reflects how much clean air can be produced in a certain period of time, and the purification efficiency reflects how many pollutants can be removed in a certain period of time, which is also a way of expressing the purification effect. For example, the CADR of a vehicle-mounted purifier is basically 10-20. Based on this, it can be calculated that the car can be purified 3-7 times in 1 hour, but it cannot directly display the degree of purification, and the purification efficiency is directly informed for 7 minutes. It can purify 80%, and it can purify 90% in 10 minutes (the value is just an example). It can be seen that the purification efficiency can be more direct than CADR. Therefore, for a specific small space, it depends on the CADR, but also on the purification rate.

CCM (Cumulative Purification Capacity) is a parameter that reflects the service life of the purifier filter. The larger the value, the longer the service life of the filter and the lower the replacement frequency. It is a cost-effective indicator of the product. If CADR reflects how fast you can run, then CCM reflects how far you can run, so CCM is also an important indicator that cannot be ignored.

Purification energy efficiency, the amount of clean air (the ratio of CADR to rated power) that an air purifier can produce per unit power consumption, is a measure of power consumption. In general, the larger the value, the cleaner is energy-saving and the purification effect is better. It is important to note that the classification of the purification energy efficiency of particulate matter is different from the classification of the purification energy efficiency of formaldehyde, so it cannot be generalized. The specific energy efficiency ratings of the two are defined as: the purification energy efficiency value of particulate matter 2 is the qualified level, and 5 is the high efficiency. For the purification energy efficiency of formaldehyde, 0.5 is the qualified level and 1 is the high.

What effect does an air purifier have on the family?

In the past two years, with the outbreak of the new crown epidemic, consumption upgrades, consumers’ awareness of respiratory health, and air purification products have also ushered in an unprecedented outbreak. Undoubtedly, air purifiers have reaped the biggest dividend from the air quality crisis. Next, let OLANSI explain to you the importance of air purifiers.

 

In fact, for high-quality families, air purifiers have become the standard for home air purification. After all, who doesn’t want to have fresh air in their homes every day, and that their families can enjoy fresh air every day? Indoor pollutants are mainly divided into several types: formaldehyde, PM2.5, benzene series and TVOC.

 

Friends who know about indoor pollution must also know that formaldehyde is the most difficult to deal with among these pollutants, which is different from other pollutants. , The volatilization period of formaldehyde can be as long as 3-15, and it has the stubbornness to repeatedly exceed the standard. Secondly, relatively speaking, formaldehyde is the most harmful. Formaldehyde can not only cause various respiratory diseases, but also cause infertility, fetal malformations, and even induce childhood leukemia, carcinogenesis and death. The role of air purifiers can be said to be very important for scenarios such as serious air pollution, sensitive people at home, and mothers and babies. Then OLANSI recommends several products to protect our healthy breathing, so that everyone is no longer troubled by air pollution:

It is no secret that smoke inhalation is harmful to the lungs. But now, scientists believe that smoke may also carry and spread infectious diseases.

 

A study found that the smoke from wildfires is filled with thousands of microorganisms, some of which are known to cause diseases, such as bacteria and fungal spores. A recent report in the journal Science pointed out that “smoke may carry and spread infectious diseases.”

 

Scientists said that because these bacteria or fungi will be adsorbed on smoke particles and travel thousands of miles and across continents, they have the possibility of spreading infectious diseases.

 

Although whether smoke-borne microorganisms may cause human infections remains to be confirmed, some scientists believe that this possibility is considerable. Because in some areas, the increase in the incidence of fungal-related diseases is positively correlated with the increase in wildfire smoke. The US Centers for Disease Control and Prevention also reminded that firefighters are at a higher risk of getting Valley Fever. Valley Fever is scientifically called Coccidioidomycosis, which refers to people who have fever and rashes due to inhalation of spores in the soil. And other symptoms.

Bacteria are so terrifying, then OLANSI recommends several products to protect our healthy breathing, so that everyone is no longer troubled by air pollution:

When you have low work efficiency, poor work quality, often criticized by leaders, etc., you may habitually think that this is caused by too tired work and decreased work ability. In addition, have you considered that it may be because the air quality in the office is too poor? A recent study by Harvard University in the United States found that office air quality will severely affect employees’ cognitive functions, including reaction time and concentration, which in turn will affect work efficiency.

 

In a day, the beaters need to stay in the office for at least 8 hours. The news that office air pollution causes various diseases among employees, ‘how can workers avoid office air pollution’ has become a topic of concern to more and more people. If you want to solve the air pollution in the office, you must first have a more comprehensive understanding of these “invisible killers” in the office.

 

In fact, the composition of air pollutants in the office is very complex. Not only the long-term release of formaldehyde, TVOC, benzene-based pollutants, ammonia, etc. from office equipment, but also various molds and bacteria hidden in central air conditioners. Long-term contact with air pollutants in these offices will cause immeasurable effects on the body. harm.

 

All kinds of molds will float in all corners of the office along with the transportation of cold/hot air from the central air conditioner. Long-term breathing of moldy air will cause bronchitis and bronchitis. In severe cases, asthma will occur, and staff with low immunity will also Headache and fever occur, causing skin surface allergies.

 

In the face of ubiquitous air pollutants, we should take a variety of measures, such as opening windows for ventilation and using air purifiers. Speaking of air purifiers, several products recommended by OLANSI are designed for most people, and the main product design is the combination of multiple filtration technologies:

Because our living environment is now polluted, there are a lot of bacteria and dust in the air. If inhaled into our respiratory tract, it will cause respiratory tract infections and cause tracheal diseases, so purifiers came into being. For the applicable people and applicable occasions of the purifier, we must pay more attention to understanding, and then let OLANSI explain it for you.

 

  • The most important thing is pregnant women. Pregnant women will feel general malaise when indoors with serious air pollution, such as dizziness, sweating, dry tongue, chest tightness, vomiting and other symptoms, which have an adverse effect on the development of the fetus. A set of scientific data shows that pregnant women who have been exposed to air pollution for a long time are three times more likely to develop heart disease in their fetuses than those born to babies born to pregnant women who breathe fresh air.

 

  • The second thing is about children. Children’s bodies are developing and their immune systems are relatively fragile. They are vulnerable to indoor air pollution, resulting in decreased immunity, delayed physical development, induced blood diseases, increased the incidence of childhood asthma, and made children The intelligence is greatly reduced.

 

  • Again, it is the middle-aged and elderly people, who have decreased physical function and often suffer from a variety of chronic diseases. Air pollution not only causes respiratory diseases such as bronchitis, pharyngitis, and pneumonia in the elderly. It can also induce high blood pressure, heart disease, cerebral hemorrhage and other cardiovascular diseases.

 

  • In addition, we want to talk about the driver, the driver has been driving for a long time, the car is lack of oxygen, and the car exhaust pollution is serious. At this time, it is necessary to equip the car with an air purifier, which can absorb the poisonous gas on the car and reduce the exhaust pollution.

Air pollution is so harmful to the human body. The next few products that OLANSI recommends to everyone are product designs for most people, and the main product design is a combination of multiple filtration technologies:
