World Health Organization definition: The standard concentration of negative oxygen ions in fresh air is 1000-1500/cm3.
Air conditioners, or some high-end appliances, will be equipped with negative ion modules. However, most of the negative ion modules on the market require higher voltages, which will affect the electrical appliances and the human body. Negative ions are not necessarily small-sized, small-sized negative ions. It can directly enter the human body and is beneficial to the human body. It also has better effects in reducing smoke and dust than the medium and large particles.
If you just want to use it occasionally, you can try small household appliances, such as air purifiers. It is recommended to increase the particle size of negative ions. The effect of removing smoke will be very good, because the negative ions themselves have the function of reducing smoke and dust. OLANSI’s small particle size negative ions are very effective and are specifically designed for secondhand smoke.
Nowadays, many families will install central air-conditioning during renovation. They will also join the central fresh air system and walk along the pipelines, but most of them are only basic ventilation and filtration, and there is no fresh air. If you want fresh air in your home, you should choose an air purifier. If it is a renovated room, consider opening it for 24 hours. It also has obvious effects on second-hand smoke, second-hand air, and formaldehyde odor.

Nowadays, many people talk about PM2.5 color change, why? Because the air quality is getting worse, the mask has become a must-have item. What’s worse, the air problem has also extended into the home, so the purifier has almost become a necessity, and the air purifiers on the market have sprung up. How do we compare Olansi’s K15A air purifier?
Exterior
With a simple and stylish appearance, the white color is suitable for any position in the home. The design of the straight barrel style has four universal wheels at the bottom, which is very convenient to move, compared to those of the fixed type. For the device, it is much more flexible. The top has a large air outlet, and the purified air is discharged from the top. Similarly, the large area means that the air volume (fresh air) will increase.
At the bottom of the K15A, there are four universal wheels, which are much more flexible than the fixed purifier. Which room needs to purify the air, push it directly there, and don’t worry about the children at home, because K15A With the child lock and pressing the two buttons of wind speed and mode, the child lock mode will be activated. At this time, even if the child (including the adult) clicks, no operation can be performed. In addition, if the top cover of the K15A is turned on after power-on, the machine will automatically power off to prevent some safety hazards. After all, these years have also seen many tragedies caused by leakage of such household appliances. And after removing the cover, take it directly to the faucet and rinse it. It is very convenient to clean. Look inside, there is a layer of net fixed below, it can also play a role in preventing children from reaching out and moving.

There is no smog in summer, but it is more necessary to open an air purifier
As soon as summer arrived, the foggy days were significantly less and the air quality gradually improved. Many people have turned off their home air purifiers, especially in the southern regions where smog was not as serious. However, most people don’t know that in the summer without smog, they should open the air purifier!
TVOC in summer
Everyone knows that winter should guard against smog, but ignore the ‘TVOC’ in summer.
‘TVOC’ refers to the total volatile organic compounds in the room, including carbon monoxide, carbonates and ammonium carbonate, and a series of toxic and harmful gases in the air. These substances will volatilize more indoors as the temperature rises in summer.
The problem of volatilization of indoor harmful gases is often more severe in summer than in winter.
For formaldehyde, a pollutant that is particularly harmful to the body, its volatile release is greatly affected by temperature. For every 1 °C rise in room temperature, the concentration of formaldehyde volatilized from wooden furniture and flooring increased by 0.15 to 0.37 times. Tiles also often contain serious carcinogenic gases such as radioactive cesium, which also spread as temperatures rise.
In summer, everyone is used to closing doors and windows and air conditioning. As a result, indoor pollutants are more difficult to reduce. In addition, if the interior of the air conditioner is rarely cleaned, the indoor bacterial microorganisms are more likely to grow and are inhaled into our respiratory tract along with harmful gases. Therefore, staying in the air-conditioned room often feels dry mouth and mouth, itching of the throat, mild symptoms of cold, and serious respiratory diseases, which is often referred to as ‘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.
Most families generally open windows for long periods of time after the renovation of the new home. However, even if you have been through the wind for half a year, it is not a cure.
Research by the National University of Yokohama in Japan shows that the release period of indoor formaldehyde is generally 3-15 years. Short-term ventilation is unable to completely remove indoor formaldehyde. These harmful volatiles will accompany the long-term existence of residence.
In addition, more people are hoping for bamboo charcoal bags, plants and fruit skins. As the saying goes, partial treatment of serious illnesses, it turns out that these effects on eliminating indoor pollution are almost negligible and can be ignored.
Olansi Air Purifier introduces air purification technology focused on respiratory health research, specializing in the creation of high quality air purification systems. High-efficiency filtration system, CADR (clean air volume) up to 800m3 / h, purification of 56~96 square meters of room. Effectively solve indoor pollutant pollution, let you breathe the cleanest air.

Air pollution is worrying, is the air purifier useful?
Due to the continuous increase of smog weather in recent years, the PM2.5 value of many cities has frequently exploded, coupled with the strong smell of formaldehyde in new home decoration and purchase of furniture, in order to breathe clean air, more and more people began to purchase air purifiers. So is the air purifier really useful? The answer is certainly yes.
The air purifier can detect and control indoor air and formaldehyde pollution, bringing fresh air to our interior.
Which includes
1) Settling particles in the air to effectively settle various inhalable suspended particles in the air such as dust, coal dust, smoke, fiber impurities, shavings, pollen, etc., to avoid causing allergic diseases, eye diseases and other diseases.
2) Remove microorganisms and pollutants from the air, effectively kill and destroy bacteria and viruses in the air and on the surface of objects, and remove dead dandruff and pollen from the air to reduce the spread of diseases in the air.
3) Effectively eliminate odor, effectively remove the strange smell and polluted air emitted from chemicals, animals, tobacco, oil smoke, cooking, decoration, garbage, etc., and replace indoor gas continuously for 24 hours to ensure a virtuous circulation of indoor air.
4) Rapidly neutralize chemical gases, effectively neutralize harmful gases emitted from volatile organic compounds, formaldehyde, benzene, insecticides, aerosol hydrocarbons, and paints, while at the same time reducing the discomfort caused by inhaling harmful gases. .
So, can the air purifier really eliminate pm2.5?
Air purifiers have become a must-have home appliance for many families. They have a small role in indoor air purification. They can detect and filter PM2.5 in the air and effectively protect the family’s respiratory health. In the smog weather, the indoor anti-mite air purifier can not be less.
Is the air purifier effective for removing formaldehyde?
First of all, we must understand that formaldehyde is produced by decoration and raw materials, and it cannot be removed for a long time. To solve the problem of formaldehyde permanently, it is necessary to remove the pollution source of the decoration or raw materials from the source. Otherwise, it can only be treated by formaldehyde, but if the formaldehyde exceeds the standard, then the treatment can not be completed. The air purifier is an auxiliary means, it is recommended to open 24 hours, which has a certain elimination effect on formaldehyde.
So what is the best way to remove air purifiers?
Most of the air purifiers are composed of HEPA filter and activated carbon filter. HEPA is mainly used to purify solid pollutants such as dust and PM2.5. The activated carbon filter is mainly used to adsorb volatile gases such as formaldehyde and odor. There are two necessary conditions for indoor air quality to meet certain cleanliness standards. First, it must be ensured that the indoor air reaches a certain number of air changes, that is, the fan built in the cleaner has a certain amount of air. Second, the purification efficiency of the cleaner must be relatively high. Clean Air Volume (CADR) is the physical quantity that quantifies the two necessary conditions above the cleaner.
In general, the larger the CADR value, the higher the purification efficiency of the purifier. That is, the clean air output ratio, which directly affects the purification efficiency. The higher the CADR value, the higher the purification efficiency of the purifier and the larger the applicable area. It can be seen that CADR is an important indicator to measure the excellence of an air purifier, but note that this is not the only or dominant indicator.

The global economy continues to grow at a high rate and environmental pollution is becoming increasingly serious. According to statistics, indoor environmental pollution has caused 35.7% of respiratory diseases, 22% of chronic lung diseases and 15% of bronchitis, bronchitis and lung cancer. Air pollution causes millions of people worldwide to die prematurely each year. In 2002, the World Health Organization clearly listed indoor air pollution as the top ten threat to human health. For some special people, air pollution will have a greater impact on them. So who is the most harmful to indoor air pollution?
Children
Because the child is developing, the immune system is relatively fragile and vulnerable to air pollution, resulting in decreased immunity, induced respiratory and blood diseases, resulting in slow body development and greatly reduced children’s intelligence. Long-term living in air pollution can increase the risk of abnormal lung function in children by 30%-70%.
According to expert statistics, the prevalence of asthma in children in China is 2-5%, and the prevalence of children aged 1-5 is as high as 85%. Therefore, the harm of indoor air pollution to children should not be underestimated.
Pregnant woman
As a special group, pregnant mothers should not only pay attention to their own bodies, but also pay attention to the small life in the stomach. The fetus is very sensitive to air quality during development. If the pregnant mother has long-term exposure to airborne pollutants during the first 6 months of pregnancy, it will increase their chances of illness and death, and cause premature birth and other problems.
Pregnant women staying in a serious air pollution environment for a long time will feel physical discomfort, may have symptoms such as dizziness, sweating, dry throat, chest tightness and vomiting, which have adverse effects on fetal development. In a long-term contaminated indoor environment, the probability of a baby suffering from a heart disease is several times that of an ordinary baby.
Old man
After entering the old age, the body functions are declining, the constitution is weaker than the young, and the resistance is relatively poor, and it is more susceptible to environmental factors to induce various diseases. Air pollution is not only an important cause of respiratory diseases such as bronchitis, pharyngitis, and pneumonia in the elderly, but also causes malignant diseases such as asthma, colon cancer, brain tumors, and Alzheimer’s disease (Alzheimer’s disease).
Living in a polluted environment for a long time will lead to a decline in liver and kidney function in the elderly. In addition, chemical pollution such as formaldehyde has a strong carcinogenic effect, which further increases the incidence of cancer in the elderly.
Office worker
Most companies are now located in office buildings. Because of the high floor and long window closure, the air flow inside is very poor. In addition, the office staff is basically indoors for a day, so it is more susceptible to indoor air pollution poisoning in terms of time probability.
If you are in an environment with poor air quality for a long time, it may easily lead to dizziness, chest tightness, fatigue, emotional ups and other discomforts, which will greatly affect work efficiency and cause various diseases. In severe cases, it may cause cancer, and the office environment becomes a watch. A healthy chronic killer that is not seen.

What is the effect of an air purifier on healthy air?
As the pursuit of modern people’s quality of life is getting higher and higher, everyone has begun to pay attention to the quality of air. However, there are still many people who are worried about the use of air purifiers when purchasing air purifiers, but rarely know that the role of air purifiers is not big, because the air is invisible, the effectiveness of air purifiers is our body. It is not easy to perceive. But today you can understand that the effect of the air purifier on the body is not big?
The newly renovated owner said: The new house has just been renovated. Although the door and window are ventilated, there is still formaldehyde. I heard that there is an air purifier specially designed to remove formaldehyde. Is it really useful?
With baby treasures said: outside is foggy days, dare not take the baby out, but also afraid to open the window, can stay in the airless room for a long time, so many bacteria, the baby always has a fever, I heard that air purification Can the device be used for removing mites and sterilizing?
The housewives at home said: Every time I cook, I have a range hood, but the evil smoke still burns me into a ‘yellow face’. I heard that the air purifier can remove smoke and dust, does it really work?
However, when you ask if the air purifier is useless, many households have already started using air purifiers, and they have become a must-have for many families. Even after many households have used air purifiers, the number of colds of the baby has decreased; after the new house is equipped with an air purifier, the green plants are longer and more lush. Although the current air is difficult to perceive that the air is difficult to perceive, let the dirty air become more and more sloppy, or ignore the purification performance of the air purifier. It is necessary to know that the human body has to breathe more than 20,000 times a day, and air quality is a key factor affecting the health of the body. One.
Therefore, you can also think that the refrigerator can be cooled, air conditioning can make the wind, you think that the air purifier can definitely give people the purification of air. At the same time, the damage caused by air pollution to the human body is chronic and invisible, so it will have a great impact on everyone’s physical and mental health in the long run. Although we can’t completely improve this problem, it can help you and your family to improve the quality of the air through air purifiers, using air purifiers, and fresh life from now on.

Does the air purifier work? Facts speak louder than words
As people’s living standards continue to improve, everyone’s requirements for air quality will increase. The development of modern industry has also made the air quality we breathe every day worse. Going out wearing a mask and going home to open an air purifier seems to be a routine movement in our lives.
After several years of development, air purifiers have gradually transformed from a comfortable consumption into a demanding consumption. However, there are still many people who have many misunderstandings about air purifiers. Some people even ridicule the air purifiers as ‘accepting IQ tax.’ So, does the air purifier work? Below we will use scientific methods to verify. In principle, 99% of air purifiers are basically negative ion technology or physical filtration technology. These two air purifiers can effectively adsorb, decompose or convert various air pollutants (generally including PM2.5, dust, pollen) , odor, formaldehyde and other decoration pollution, bacteria, allergens, etc.).
Air purifiers have been developed so far, and many users have experienced it. It also proves that its role is very good.
In short, the home is our most intimate harbor, and we must not let the bacteria and viruses in the air erode our family. Go home and open the air purifier to create a good room to protect our favorite people.

The researchers analyzed the 13-year data of 86 million Americans and found that the more serious the air pollution, the more violent crimes.
As we all know, air pollution has a fatal impact on human health, but scientists are now worried that air pollution may also make some people become violent criminals. In a large-scale study, researchers analyzed data from 86 million people in the United States over the past 13 years and found that when air pollution becomes severe, there are more violent crimes. Researchers believe that particles and toxic gases in the air can interfere with the normal functioning of the brain, making people more likely to be aggressive.
Particles and toxic gases in the air can interfere with brain function, making people more likely to show aggressiveness
The researchers concluded that air pollution not only affects people’s health, but also affects people’s behavior. It is not surprising that more violent crimes occur in crowded and polluted cities. However, researchers are not simply observing polluted areas. Whether more violent crimes have occurred.
Instead, they studied the increase or decrease of criminal records in 301 different regions (involving cities, suburbs, and rural areas) over time and whether they were related to the air pollution index. In short, researchers want to know if the crime rate will rise when air pollution increases. For non-violent crimes such as theft, the answer is ‘no’; but for violent crimes, there is a real connection between the two.
The research team wrote: ‘Our research has determined that air pollution is associated with county-level violent crimes… We have found that violent crime increases by 1.17% for every 10 mg/m3 increase in fine particulate matter daily; For every 10 ppb increase in concentration, violent crime increased by 0.59%. This effect is mostly caused by an increase in attack events.’
Violent crimes rise when air pollution becomes more severe, whether in poor or affluent areas. Previous experiments in mice and dogs found that those exposed to high concentrations of fine particulate matter (such as particulate matter in diesel smoke) The animals in the field show ‘stronger aggression, territorial awareness and a preference for instant rewards.’
Similarly, exposure to air pollution can also increase anxiety, leading to criminal and unethical behavior.
‘The impulsive and aggressive response may explain why air pollution is associated with increased violence and is not associated with non-violent crime,’ the researchers wrote. ‘We carefully interpret this result as an air pollution that is acute to neurological and behavioral health. Evidence of impact requires further study of its pathways of influence.’ Previous studies have shown that ‘metal constituents in particulate matter, especially manganese and mercury, may cause more aggressive and violent behavior.’

Serious air pollution can quickly degrade children’s brains
Nowadays, in heavily polluted areas such as Mexico and Asia, many people choose to wear masks. In the world’s major cities, including Mexico City, Jakarta, New Delhi, Beijing, Los Angeles, Paris, and London, humans are polluting the air at a rate that the Earth cannot afford.
Most people think that air pollution is like dust, as small as the hair diameter (particulate matter), or even smaller (ultrafine particles). It is well known that respiratory diseases such as pneumonia, bronchitis and asthma are associated with air pollution. About 1 million children die of pneumonia each year, and more than half of them are directly related to air pollution.
The volume of the particles is very small and can enter the bloodstream from the lungs and enter the brain through blood circulation. In such cases, inflammation of the brain can occur, leading to loss of cells in the central nervous system and possibly increasing the risk of dementia such as neurodegenerative diseases, cognitive deficits, and Alzheimer’s disease.
Although aging can cause mild neurodegenerative diseases, severe air pollution can accelerate the deterioration of nerve cell inflammation. To make matters worse, such severe air pollution accelerates neurodegeneration at the peak of brain development (childhood).
This is indeed the case. Today, millions of children around the world breathe polluted air, which may expose them to premature cognitive deficits and the risk of neurodegenerative diseases such as Alzheimer’s disease. This is the status quo that we continue to damage the child’s brain and shorten its life.
Unexplained cause of child death
In the late 1990s, neuropathologist and paediatrician Lilian Calderón-Garcidueña published a report stating that early signs of neurodegeneration were associated with air pollution by testing the brain tissue of adults, children and dogs that were “accidentally” dead and of unknown cause. .
These brain organizations have one thing in common – they all live in Mexico City, one of the most polluted cities in the world.
Further research shows that there is often a rather serious situation in scientific reports. In diseased animals and humans, their unhealthy brain slice microscopic images show that tiny black spots surrounded by inflamed tissue are particles and ultrafine particles. Around the inflamed spots, you sometimes see streaks similar to scars, and you can see pink stems. These are the common amyloid plaques in the brain after death in patients with Alzheimer’s disease. I joined Lilian’s team as an expert in cognitive development neuroscience and neuroimaging. We use behavioral tests and shoot images of the target brain area to explore signs of precocious cognitive deficits in humans.
Children’s brain cognitive ability is significantly reduced
We found that the cognitive abilities of children in Mexico City decreased significantly compared to the normal population and other children with similar age, gender, family and neighborhood backgrounds living in less polluted areas. We can identify abnormal cognitive deficits in key brain development areas, the prefrontal, temporal, and parietal lobes of the cerebral cortex. We also found atypical cognitive phenomena in the auditory brainstem, which may be related to language developmental disorders. Children’s neuroimaging is consistent with the most severe damage in the white matter, and white matter provides a conductive communication link. We can prove that in many cases, the symptoms of neuroinflammation in children in Mexico City are much more serious than in children. Today, consistency can be drawn from similar findings in other large cities or other researchers: air pollution damages the brains of millions of children, so protecting them is critical to public health.

Air pollution sounds alarm: air pollution is the worst in Turin, Paris and London
A few days ago, the data in the air quality report released by the European Environmental Agency AEA showed that Italy is the country with the largest number of deaths due to nitrogen dioxide in the EU countries, with an annual number of 14,600 people, which also tends to be critical in environmental pollution indicators. Prior to the 2016 environmental report, there were 3,000 people killed by ozone, and 58600 people died of PM2.5 exceeding the standard, ranking second in the EU.
According to the overall data, there are 372,000 people in the EU due to environmental pollution, which is a decrease from the 391,000 in 2015. Although Italy’s indicators are not good, but the number is also decreasing compared with 2015. In 2015, there were 20,000 people killed by nitrogen dioxide in Italy.
According to the 2017 data, the largest PM2.5 values are in Eastern European countries (Bulgaria, Croatia, Czech Republic, Poland, Romania, Slovenia, etc.) and Italy. From the perspective of big cities, Turin, Paris and London are the most polluted cities in the EU. From the perspective of small cities, the content of PM2.5 and PM10 in Padova air quality is significantly exceeded, and the environment of 2 million Italians lives. All air indicators tend to be the lowest of the EU indicators. Relevant people said: “Italian air quality data is a cause for concern. We are the only country in the southern European countries whose air quality tends to be critical. This is a serious health injury to Italian residents, especially the elderly and children. We must be serious. Face this problem and solve it.
