About the procurement of air purifiers by governments around the world
As the variant new coronavirus has made the world’s epidemic situation worse, daily preventive measures have become more important. Countries around the world have successively introduced measures to close cities to reduce the deterioration of the local epidemic. However, when the closure was lifted again, governments of various countries began to pay attention to the air quality in key places.
The German government introduced policies to improve school air quality and invited tenders to purchase air purifiers. Many businessmen took this opportunity and placed orders for air purifiers. With the changes in the epidemic situation, governments around the world will also issue a series of policies to purchase these anti-epidemic products which use in public places.
OLANSI K15 air purifier is very suitable for use in schools, offices, and commercial places. The high CADR value and matching H13 filter can give people a healthy and clean space. If you are also optimistic about this market opportunity, please do not hesitate to contact us. Once the local businessmen won the bid, they need a lot of air purifiers in a short time. Therefore, placing your order in advance will keep your inventory sufficient.
If you want to know more product details, pls contact us.
Why is it recommended that you use Olansi H13 HEPA filter?
HEPA H13-H14 are within the highest tier of HEPA and are considered medical-grade quality. Whereas H10-H12 filters only trap 85-99.5% of all particles that are 0.1 microns in diameter, HEPA H13 and H14 trap 99.95% and 99.995% of such particles, respectively.
Medical-grade HEPA filters are commonly used in pharmaceutical manufacturing and electronic control rooms because they have a greater particulate retention rate. This means medical-grade HEPA filters are more efficient in removing harmful toxins from the environment. The web of fibers that make up these filters is even denser than True HEPA and thus traps the smallest particles at a higher rate.
Most HEPA filters on the market can only trap the virus but can’t kill it or remove it，so the accumulation of a large number of virus bacteria will also reduce the service life of the filter. However, special materials are added to our own HEPA filter in air purifier, which can achieve high-efficiency sterilization and reduce damage to the filter. And there is formal test report to confirm this claim. If you want to know more details, please contact us. Let us help you open your market.
Why do we recommend using negative ion air purifier but ozone generator?
Negative ion air purifier works by electrostatically charge negative ions internally and disperse them into the air. Like a magnet, the released negative ions will merge with positive ions particle in a room. This includes dust mites, mold/ mildew, pollen, pet dander, bacteria, and viruses. The bonded ions will fall due to the increased weight leaving the air free from any contaminants.
A negative ion is an oxygen atom with an extra electron. It is ODOURLESS and vital to health.
The ozone generators advocated on the market are unsafe. why?
Ozone is a highly reactive chemical. Because of its ability to react with the molecules in the air, it has an uncanny ability to remove strong odors and pollutants. But ozone doesn’t magically lose its reactive abilities when inhaled. On the contrary, when ozone is inhaled by humans, it remains just as reactive. This reactive nature is what makes ozone dangerous to humans and other forms of life.
When inhaled, ozone can create a reaction in the lungs. Even at low levels, this can create a wide range of health problems, particularly with the lungs. They can inflame and damage airways and make the lungs more susceptible to infection.
First, ozone can be a contributor to chest pain and coughing. It can cause shortness of breath, and irritation to the windpipes. These problems can inflict anyone who breathes in ozone contaminants, but they are especially potent for people with respiratory conditions such as asthma and allergies. Ozone makes it more difficult to breathe deeply, causing someone to struggle with getting enough pure oxygen for normal activity and daily function.
Ozone can also cause issues with the throat. This can come in the form of mild to serious coughing and, depending on the exposure levels and overall health of the patient, can disrupt normal daily functions.
On the contrary, more and more proofs prove that negative ions are beneficial to the body.
Negative ions breathed in high concentrations for prolonged periods of time give us energy, vitality and most importantly fight the negative effects of positive ions. We want to be around negative ions as much as possible. Negative ions are extremely important to having a healthy, disease free body.

In this special period, it has become a consensus among the people to go out and wear masks. Masks block the virus, but you ca n’t wear them at home, how can you ensure healthy breathing indoors? Some families have bought air purifiers, but most can only filter dust, not sterilize. After a period of time, the filter element is filled with dust, and if it is not replaced in time, bacteria will breed, and the purifier has become a major source of pollution. So is there a filter that is both sterilized and resistant to viruses? This is a silver ion composite filter containing anti-bacterial and anti-virus!
1. Silver ion can cleave new coronavirus
Silver is a natural inorganic antibacterial disinfectant, and the silver ions it releases play a role in sterilization and disinfection. In view of the fact that the new coronavirus is currently not treated with special drugs, silver ion can be used as another way to prevent the new coronavirus.
The anti-viral ability of silver antibacterial materials In the article “Efficient and rapid cracking of SARS coronavirus and other microorganisms by metal catalysts”, the research team compressed silver / alumina into discs and dropped Vero cells that support SARS coronavirus proliferation On the disc, the virus toxicity on the plate was compared after 5 min and 20 min, respectively. The results showed that the toxicity of SARS coronavirus in Vero cells decreased to a very low level at 5 minutes of exposure. At 20 minutes, the virus was not found to have toxicological effects on cells. However, in the corresponding control group, the virus showed a typical cytotoxic effect, which shows that silver / alumina has a strong antiviral ability.
The paper “Discussion on the Inactivation Effect of Nanosilver on Influenza Virus H3N2” also concluded through experiments: Nanosilver has a direct inactivation effect on influenza virus H3N2. The oxidizability of active silver ions> nano silver, that is to say, the active silver ions have a better direct inactivation effect on influenza virus H3N2. Silver ion was recommended as a disinfectant during the SARS period: Silver ion was listed as one of the disinfectants by the No.302 Hospital of the People’s Liberation Army of the Ministry of Health, General Logistics Department.
2. Aussie antibacterial and virus removal composite filter
The antibacterial and antiviral filter newly developed by Oransi has newly added copper and silver ion antiviral materials to inhibit the proliferation of bacteria and mold adhering to the surface of the filter and provide clean and fresh air indoors. The first layer: copper and silver ion anti-virus PET skeleton
Newly developed Cu2Ag + antibacterial and antiviral technology, using PET skeleton as a carrier, carrying copper and silver ions, and then synergizing with medical H13 grade HEPA filter to play the role of bacteria isolation, sterilization and antivirus. SARS (atypical pneumonia), H7N9 (avian influenza, coronavirus), H1N1 (respiratory influenza virus) and other viruses have obvious removal effects. The second layer: H13 medical grade HEPA
The H13 medical grade HEPA filtration accuracy is less than 0.3 microns, which can capture and reduce 99.97% of fine particulate matter in the air, such as pollen, pollutants, and allergens, and reduce the carrier of bacteria and viruses in the air.
The third layer: modified activated carbon
Modified activated carbon can filter out formaldehyde / VOCS and other gaseous pollutants to keep the air fresh.
3. The principle of silver ion sterilization and virus removal
The first step: effect on enzymes and amino acids in microorganisms Silver ions are first adsorbed on the surface of the bacterial cell wall, destroying some of its physiological functions. When the silver ions are aggregated and reach a certain limit, they penetrate the cell wall and enter the interior, staying on the cytoplasmic membrane, inhibiting the activity of enzymes in the cytoplasmic membrane Cause the death of microorganisms such as bacteria. The second step: destroy the barrier structure of microorganisms The silver electrolyte can destroy the cell membrane, loosen the cell membrane, rupture the cell membrane, and leak the cytoplasm. The bacteria are then destroyed. Silver ions can penetrate into cells and interact with protoplasts, so that the protoplasts contract and condense and come out. The third step: destroy the DNA molecules of microorganisms Silver and other metal ions can also act on specific sites on bacterial DNA molecules, destroying the DNA molecular structure. The research by Thuman and Gerba pointed out that silver ions can coagulate nucleic acids, causing cross-linking of DNA molecules, or catalyzing the formation of free radicals, which leads to the breaking of chemical bonds on DNA molecules.
What is HEPA HEPA (High-Efficiency Particulate Air) is the most recognized high-efficiency filter material in the world. The particles having a particle diameter of 0.3 μm can be filtered, and the filtration effect is about 99.97% or more. That is to say: only 3 particles per 10,000 particles can penetrate the HEPA filter membrane.
How is the HEPA filter grade divided? HEPA filters and the like are subdivided into G1-G4, F5-F9, H10-H14 and U15-U17 according to the current European scale. The best known H13 and H14 filters are high efficiency air filters. The HEPA filter grade is subdivided according to the American ASHRAE rating. H11, H12, H13, and H14 are equivalent to the US M15, M16, M17, and M18 grades. The unfolded area of HEPA determines the quality of the filter, and its filtration efficiency is proportional to the expansion area. The smaller the unfolded area, the shorter the service life of the filter. On the contrary, if the area is too large, the wind pressure will increase and the air volume will be affected. Therefore, a HEPA filter that is more suitable for air purifiers must be accurately designed and adjusted several times to determine the final deployment area.
As a manufacturer of air purifiers, Olansi is more professional in the production of air purifier filters.A variety of high quality filters are available for customization. At present, we have a special deodorizing filter that has passed the Korean KC and CA certification, which proves our ability in the production of filters. The following is the internal test data of the 8 cubic meter test space provided by the supplier (for reference only).
Choose Olansi and choose a comfortable and healthy future.
Poor air quality can cause negative effects towards your health such as allergies, respiratory illnesses, and skin problems. Considering that we spend more than 90% of our time indoors, it’s important that indoor air is clean and pollutant-free to protect our health and wellbeing.
Indoor air quality statistics
According to the EPA, indoor air pollution is among the top 5 environmental risks to public health. In fact, indoor air quality can be up to 5 times worse than outdoor air quality!
Effects of indoor air pollutants towards your health may range from symptoms such as eye and throat irritation, to respiratory diseases that may arise from long term exposure to indoor pollution.
What is in indoor air
Indoor air could harbour a range of pollutants unseen to the naked eye. Airborne particles such as diesel exhaust, carbon, dust, smoke, fibres, and pollen easily enter the home through opened doors and windows.
Cooking odours, pet odours, chemicals, sink or drain smells contribute to an unhealthy variety of unpleasant and toxic household odours and gases.
Around the home, furniture, office equipment, cleaning supplies, paint, glue and varnishes are just some of the unhealthy Volatile Organic Compounds (VOCs) that are harmful to our long term health.
Not to mention, there could be a range of microorganisms such as bacteria, mould, and viruses, floating around our home!
Sources of indoor air pollutants
You may think your home air quality is perfectly fine, but these pollutants are well hidden from the naked eye. Some don’t emit a distinct smell or show obvious physical signs, so you barely notice them around your home.
However, the sources of these indoor air pollutants are everywhere in our home. Pollutants such as mould and mildew could be lingering in our bathroom and laundry room. We could also be exposed to Volatile Organic Compounds (VOCs) from paint, varnishes, upholstery, furnishing and carpets.
That’s why having an air purifier is so important at home. Air purifiers help to clean the air of unwanted pollutants. They are especially useful for those suffering from asthma or allergies.
Air purifier benefits
Air purifiers are appliances that filter out pollutants such as dust, pollen, viruses, bacteria, and odours from indoor air. With the help of air purifiers, we can improve indoor air quality and protect the health of ourselves and our families.Cleaner air provides long term benefits by reducing respiratory diseases and airborne infections caused by indoor air pollutants. Moreover, air purifiers also help to improve air circulation and eliminate mould spore buildup.Indoor air pollutants are harmful to long term health, so consider investing in an air purifier to improve indoor air quality at home.

In recent years, air pollution is serious, and the outside is often thick smog. The air quality monitoring webpage shows a red pass, and even a purple explosion! In the face of outdoor air pollution, you may choose to hide indoors and try to go out as little as possible. However, the indoor air actually has a variety of pollution, so don’t take it lightly. Let us look at the main sources of indoor air pollution.
Closed doors and windows can not stop PM2.5!
The first source of pollution is air pollution from the outside, with familiar particulate matter (PM). The suspended particles are measured in micrometers (μm), the suspended particles with a diameter of less than or equal to 10 microns are called PM10, and the suspended particles with a diameter of less than or equal to 2.5 microns are called PM2.5.
Why is this different? Because the damage of suspended particles to the human body varies according to their size. Our nasal filtration limit is about 30 microns, which can block hair and fine sand. The bronchial filtration limit is about 10 microns, which blocks pollen and mold. The limit of alveolar filtration is about 2.5 microns. PM2.5 is very small in size and can pass through the alveoli, directly into the blood circulation, which affects the whole body and causes a variety of injuries.
PM2.5 can adsorb harmful substances such as lead, cadmium, arsenic and manganese, which is very harmful to children. Because the proportion of children’s breathing and body weight is higher than that of adults, the time spent indoors is long. If there is too much indoor PM2.5, Children’s learning and language memory decline, it is difficult to concentrate, red eyes, dry itching, easy to have allergic conjunctivitis. The skin condition is worse and it is easy to redden and itchy. When the mucus of the respiratory tract increases, the bronchi will induce asthma. More than 50% of young children who die from pneumonia are associated with indoor air pollution.
The effect of PM2.5 on adults is also very comprehensive. In the respiratory system, it can cause asthma, lung cancer, and chronic lung obstruction. In the cardiovascular system, it is easy to cause angina, myocardial infarction, and arrhythmia. PM2.5 will increase our metabolism, gain weight and gain diabetes. PM2.5 also harms the brain, and it is easier to get diseases such as stroke, dementia, and neurodegeneration. The researchers found that for every 5 μg/m3 increase in PM2.5 exposure per year, the risk of death increased by 7%. Even in the case where the PM2.5 is lower than 25 μg/m 3 , there is such a correlation.
According to the World Health Organization, about 4.3 million deaths each year are related to indoor air pollution. Common causes of death include stroke (34%), ischemic heart disease (26%), chronic lung obstruction (22%), and pneumonia (12). %), lung cancer (6%).
The most troublesome thing is that the diameter of PM2.5 is much smaller than the gap between doors and windows. Even if the doors and windows are closed, the floating particles are completely open to the suspended particles. Stay indoors, still subject to the high concentration of PM2.5 outdoors!
Burning gas and candles inside will pollute the air.
The second source of indoor air pollution comes from indoor combustion. We cook in the house and warm in the winter. We need to burn gas stoves, stoves and other equipment. In the combustion process, carbon dioxide, nitrogen monoxide, nitrogen dioxide, sulfur dioxide, formaldehyde and the like are generated. If ventilation is poor, it may cause dizziness and headache.
Exhaust gases from steam locomotives often contain nitrogen dioxide (NO2), which enters the room through open windows. If the garage at home is next to the doors and windows, pay special attention to it.
A large number of volatile organic compounds (VOCs)
Have you ever smelled a taste when your home has just been renovated, just painted, or just put on new furniture?
Decorative partitions, cements, and furniture may have volatile organic compounds (VOCs). The most dangerous substance is formaldehyde. The formaldehyde is widely present in paints, coatings, partitions, wooden furniture and adhesives, especially high humidity and high temperature, which accelerates the volatilization of formaldehyde. Excessive exposure to formaldehyde can irritate the nose, throat, eyes, and skin, damage our respiratory tract, and are carcinogenic. These building materials and furniture may continue to release volatile organic compounds for months or even years.
Cleaning supplies are another source of indoor pollution. When cleaning the house, we will open the kitchen cleaner, the toilet cleaner, and wash it out. Then we will put a wax on the floor, put a fragrance in the toilet, or spray the insecticide in the corner. These daily necessities often contain volatile organic compounds, which easily irritate the skin and respiratory tract, and even affect the central nervous system, causing fatigue and dizziness, as well as liver and kidney function, causing chromosome damage.
Perfume, nail polish, nail polish, hair gel, deodorant, anti-mosquito, correction fluid, insecticide, brightener, computer, scented candle, etc., which are often used by everyone, are also sources of volatile organic compounds.
Spreading biological pollutants
In our living environment, bacteria, dust mites, molds, fungi and other organisms can be found everywhere, making people allergic or infected. For example, after heavy rain, wet carpets, walls, and ceilings may be moldy, and mold cells can be rotated around the city with the air. Bedding is not often changed, it will be mixed with a lot of dander and dust mites. At the toilets and sinks where water is accumulated, air conditioners, dehumidifiers, and air-conditioning filters are hotbeds of microbial growth. These indoor microorganisms may cause infectious diseases, which may cause allergies to adults and children, affecting the respiratory tract, skin, eyes, and nose. Waiting for health.
Cigarettes, incense burners, and aromatherapy are all sources of pollution!
Cigarettes release thousands of chemicals and compounds such as nicotine, tar, and carbon monoxide. Hundreds of these are toxic, and there are nearly one hundred carcinogens that can damage organs throughout the body. Not only smokers are smoked. People who are not smoking but smoke second-hand smoke are deeply affected. Nowadays, although there are regulations and regulations in public places, the family space should still pay attention. If the family wants to smoke, they must ask him to go outdoors and ventilate to avoid the smoke pollution of their families.
Incense burners and aromatherapy are of course also sources of indoor air pollution, and long-term exposure is definitely harmful to the health of the family.
Clean the air and work hard together!
After reading so many sources of pollution, everyone may be surprised. The original indoor air pollution is much more serious than we imagined, and it unwittingly infringes on our health. In order to reduce indoor air pollution, we must start from two aspects, one is to reduce pollution sources, and the other is to filter air.

Indoor air pollution is much more dirty than you think
When it comes to air pollution, especially the office workers who live in big cities, they are familiar with the term ‘smog’. It can be said that everyone has learned the ability to ‘swallow the clouds and spit’ every day without knowing it. I don’t know how many harmful substances are sucked. Even those who have iron cores and lungs can’t help but absorb the “essence” of the heavens and the earth for a long time.
Outdoor air pollution cannot be ignored, and indoor air pollution should cause concern. Some people may be confused. The interior is a closed space. As long as the doors and windows are closed, how can it be polluted? Let’s see what factors are there.
Harmful substances such as formaldehyde generated in newly renovated rooms, and the emission of outdoor polluted air caused by air flow into indoors, indoor smoking, and other harmful gases, or the harmful gases generated by long-term closed doors and windows, cause indoor air pollution more than outdoor A serious and important factor.
With the development of science and technology, on the one hand, the indoor activities of human beings have greatly increased, and on the other hand, due to the serious pollution of indoor and outdoor air, they are always threatening human health. Indoor air pollution damage is not only our generation, but also affects our children. So, do you think air pollution has nothing to do with you? Do you still think that going out with a mask can avoid air pollution? Many people go out to wrap themselves very tightly, thinking that this can avoid pollution, but the indoors are also the focus of air pollution.
Life is breathing
A German man closed his breath for 22 minutes and 22 seconds, breaking the world record and not breathing in pure oxygen to close the air for 10 minutes and 12 seconds.
Breathing is invaluable for everybody we sit in. We inhale 12 cubic meters of air a day, which is equivalent to a 3 ton truck; and we breathe 28,800 times a day; we can not eat for 7 days, 3 Do not drink water in the day, but we can’t breathe for 3 minutes;
However, we spend 70% of the time indoors, for urban residents, 70% to 90% per day, home, office, shopping malls, cinemas, gyms, supermarkets, etc., so how is the indoor air to us? importance;
Cognitive Misunderstanding of Indoor Air Pollution
Misunderstanding 1: Cover the odor with air freshener
Air fresheners and perfumes can only mask the odor of pollutants. In fact, the original harmful pollutants still exist in the room, continue to affect and endanger the health of the body, and inferior air fresheners will become The source of indoor air pollution increases the degree of pollution.
Misunderstanding 2: There is odor and pollution
Among the toxic and harmful gases, some in the case of serious pollution, the concentration is greater than the human odor threshold, you can feel the obvious odor, some pollution due to their low concentration, the human sense of smell is not smelling of. At the same time, the complex smells of various substances mixed together are difficult to distinguish. Therefore, it is inaccurate to judge what pollution is by smell.
Misunderstanding 3: The use of environmentally friendly materials during renovation is not polluted.
Qualified materials mean that the content of toxic and hazardous substances is not exceeded, but not. Therefore, if the same material is used in a large amount in one room, the indoor air quality may be unqualified or even exceed the standard due to the additive effect.
Misunderstanding 4: Indoor planting can purify the air
It is generally believed that green plants have the effect of purifying air, sterilizing and vacuuming, and removing toxic substances. However, the action of plants is characterized by slow speed, long time, and very limited absorption. Some plants can produce some unpleasant smells indoors, pollen or consume oxygen in indoor air, but increase indoor air pollution.
Misunderstanding 5: Harmful gases come from renovation
This is an incorrect view. For example, the main source of ammonia is concrete with additives such as antifreeze, and ammonia can be released from human waste; cigarette smoke and kitchen smoke can produce formaldehyde, benzene, TVOC, etc. Contaminants. In China, due to the large number of applications of various benzene-containing solvents, the common presence of benzene in indoor and outdoor ambient air is relatively low. Relatively speaking, the proportion of benzene pollution generated by cigarette smoke is relatively low, but this indicates that the degree of indoor air pollution in China is more serious.
Misunderstanding 6: Purify the air inside the car with perfume
After the new car leaves the factory, the concentration of toxic gas in the car is high, and the volatilization time can last for more than 6 months, which can cause dizziness, nausea, drowsiness, cough, sneezing and other discomforts, and even lead to serious diseases such as leukemia. At present, many perfumes are not naturally extracted.
Misunderstanding 7: Fortunately
Everyone’s physical fitness and resistance adaptability are different. Not all people will develop in the same harsh environment, so some people are lucky. This is not true. According to surveys of relevant international organizations, indoor air pollutants that are harmful to health are found in 30% of new and rebuilt buildings in the world, and 68% of diseases are caused by indoor air pollution.

When it comes to air pollution, the first thing that people think of may be smog, PM2.5, dust, and formaldehyde, but they often overlook important points: microbial contaminants such as bacteria, fungi, and viruses. According to a report in the Journal of the Royal Society of B (Biosciences), the microbes that we ‘co-located’ include more than 7,000 bacteria and more than 2,000 fungi, many of which may induce various acute infectious diseases. Pathogenic bacteria. Indoor bacterial contamination is a serious threat to human health and can cause various diseases such as various respiratory diseases, asthma, and building syndrome.
Biological pollution
Definition: Pollutants, allergens and other pathogens and allergens that are harmful to humans and organisms pollute water, gas, soil and food, affecting biological production and endangering human health. For example, pollution caused by bacteria, aphids, SARS viruses, and avian influenza viruses.
Characteristics of biological pollution:
First, it is difficult to predict, and it is difficult to predict when and where foreign creatures will invade.
Second, the incubation period is long. After an alien invasion, the incubation period lasts for several years, even decades. Therefore, it is difficult to be discovered and it is difficult to follow up.
The third is destructive, unconsciously, various rashes, viral infections, etc. appear on the skin.
Biological pollution can be divided into: according to different species:
Indoor biological pollution includes bacteria, fungi (including fungal spores), filter viruses, dust mites, Legionella, animal dander and biologically active substances, Escherichia coli, Staphylococcus aureus and the like.
Biological pollution can be divided into four categories:
First, mold, it is the main cause of allergic diseases
The second is pollen from plants, such as the sycamore pollen mentioned above.
The third is bacteria and viruses carried by humans, animals, soil and plant debris.
The fourth is dust mites and hair and dander from cats, dogs and birds.
Raw material pollution
In the early stage of collection and processing of food raw materials, many bacteria are often attached to the surface, especially fruits, vegetables, meat and aquatic products with damaged surfaces. Cooking utensils and tableware are contaminated.
Processing pollution
Processed foods are mostly packaged foods, generally cleaner, but also subject to secondary pollution. When the sanitary condition of the kitchen is poor, the bacteria floating in the air will settle to the surface of the food; during the cooking process, if you do not pay attention to the separation of raw and cooked, the bacteria will be transferred from the fresh food or semi-finished products to the cooked food, causing the food to cross. Pollution; food cooking and processing personnel can directly or indirectly cause bacterial contamination of food through their hands, clothes, respiratory tract, hair, etc. if they do not pay attention to personal hygiene or infectious diseases; seasonings used in cooking and processing (such as soy sauce) ) and if water contains bacteria, it can also cause bacterial contamination of food.
Indoor pollution
For example: air conditioning pollution
When the air conditioner circulates through the air duct, the bacteria and microorganisms carried in it gradually become more and more, and a secondary pollution source is formed, which causes the bacteria to multiply.
Food contamination
Harmful microorganisms and parasites or eggs contaminate food, which can cause food to spoil or produce toxins, poisoning people after eating, or causing parasitic diseases.

Indoor air quality has always been a public blind spot for public awareness
Tsinghua University released the ‘National Indoor Indoor PM2.5 Air Pollution Research Report’, which was jointly initiated by the Department of Electronic Engineering of Tsinghua University, the Building Environment Monitoring Center of Tsinghua University and the Southern Weekend Green News Department.
The indoor PM2.5 intake is 4 times that of the outdoor; during the sampling period, there is 1/3 of the time, and the indoor air is at the ‘pollution’ level. Under the same external conditions, the indoor level of the PM2.5 above the 17th floor is the best, and the indoor level below the 8th floor is the worst. The indoor level of the office environment is slightly better than the living environment.
Recently, indoor PM2.5 air pollution has gradually received attention from all parties. At the end of 2014, researchers in Shenyang sent professional testers to check indoor PM2.5 for free in the registration family, and planned to collect 1,000 survey samples. In early 2015, Wuxi began to set up 75 monitoring in 17 public places in the city. Point, detecting indoor air quality; in Barcelona, Spain, the micro-assembly laboratory (Fab Lab) is also engaged in the collection of relevant air quality data, the laboratory director Thomas Diez told Southern Weekend reporters, the laboratory is collecting worldwide Volunteers recently installed two sensing devices in China.
However, the traditional detection method has the problem of poor generalization. ‘What we have been very annoyed in the past is how to obtain the indoor air data of the country, the research and testing by researchers everywhere, the personnel and the cost are too high,’ said Mo Jinhan, an associate professor at the School of Architecture at Tsinghua University.
In the eyes of Zhang Lin, who has been researching wireless sensor networks, sensors and big data, coupled with low-cost and cloud-calibrated technology innovations, offer new possibilities for large-scale, all-weather environmental data monitoring.
‘The significance of air quality big data lies in the fact that we no longer use a small number of sampling tests to estimate the overall situation. Instead, we directly conduct a panoramic tracking and investigation of the participants’ lives, which is equivalent to giving the public a more accurate perception of the air. The ability of quality.’ Zhang Lin, the research project sponsor and associate professor of electronic engineering at Tsinghua University, said that the original intention of his research was to encourage the society to use environmental data instead of emotional judgment to look at environmental issues. In addition, they also use the cloud calibration function to reduce the error of small sensors.
