According to the Science Daily, air pollution, even moderate pollution, has been seen as a risk factor for increased stroke. A recent study by scientists at the Beth Israel Deaconess Medical Center in Boston, Massachusetts, and Boston University School of Medicine has shown that long-term exposure to air pollution can impair brain structure and cognitive function in middle-aged and elderly people.

In an article published in the journal Stroke, the researchers investigated more than 900 subjects in the Framingham Heart Study and found evidence of smaller brain structures and more subtle cerebral infarctions. It is a “static” ischemic stroke that is caused by blockages in the blood vessels that supply the brain.

The study assessed how far the subject’s living quarters were from the main road and used satellite imaging to assess the longer-term exposure of fine particles to suspended particles, which are 2.5 meters in diameter, also known as the 2.5-meter-diameter particles. For PM2.5. These granules come from many sources, including power plants, factories, trucks, motor vehicles, and burning wood. They can go deep into the lungs, and other studies have shown that PM2.5 is associated with an increasing number of cardiovascular patients in the hospital, such as heart disease and stroke.

‘This is one of the first studies to investigate the correlation between air pollution and brain structure,’ says Elissa Wilker, a researcher at the Cardiovascular Epidemiology Laboratory at the Israel Women’s Deacon Medical Center. He is also a member of the Epidemiology and Danger Program exposed by the Harvard Chen Zengxi School of Public Health (HSPH) Department of Environmental Health. ‘Our findings suggest that air pollution is closely related to the insidious structural brain aging effects, even in individuals without dementia or stroke.’

Participants in the study were individuals over 60 years of age who did not have Alzheimer’s disease and stroke. The assessment included brain capacity – age markers associated with brain atrophy; hippocampal volume, which reflects changes in the brain region that control memory; high density of white matter, which can be used to measure pathology and aging; and hidden Cerebral infarction.

The study found that PM2.5 in the air increased by 2 μg/m3 – a common growth in New England and New York, as well as in large cities such as New York – leading to an increased likelihood of occult cerebral infarction and reduced brain capacity. This effect is equivalent to about one year of brain aging.

‘These results are an important step toward helping us understand what’s going on in the brain,’ Wilk said. ‘As for the possible mechanisms by which air pollution affects brain aging, it is still unclear, but systemic inflammation caused by fine particles deposited in the lungs is likely to be very important.’

‘This study shows that PM2.5 in the air increases by 2 μg/m3 – a common area of ​​PM2.5 in the US metropolis – people living in heavily polluted areas are more likely than people living in lightly polluted areas. Brain capacity is an average of 1 year old, and their risk of developing a static stroke is 46% increased,’ said Sudha Seshadri, a professor of neurology at Boston University School of Medicine and a senior investigator of the Framingham Heart Research. .

‘This is really worrying because we know that static stroke increases the risk of dominant stroke and development of Alzheimer’s disease, walking problems and depression. We now plan to investigate the long-term effects of air pollution, which is more sensitive to MRI. (MRI) measurements, brain atrophy, and other risks, including the effects of stroke and senile dementia.’

Smoking is the ‘culprit’ that causes indoor PM2.5 to soar

Smoking is the ‘culprit’ that causes indoor PM2.5 to soar

Hepa Air Purifier,Hepa Air Purifier,Air Purifier

In addition to the well-known nicotine and carbon monoxide, cigarettes, cigars and pipes produce a lot of tiny particles in the case of incomplete combustion. Most of these particles are only about 1 micron in diameter, which belongs to the category of PM2.5. These include 69 carcinogens and 172 harmful substances, which are the leading risk factors for lung cancer. The harm of second-hand smoke is mainly carbon monoxide and PM2.5 released during smoking. These two substances are also abundant in automobile exhaust. When the indoor PM2.5 concentration exceeds the standard, people may have symptoms such as cough, slight dizziness, headache, and nausea.

Carbon monoxide gas is colorless, odorless, and non-irritating. It is very common in nature, but its content is very small. After inhalation, the red blood cell oxygen supply capacity will decrease, and the body will be deficient, causing dizziness and vomiting. Serious cases may also lead to coma and even Suffocation and death. Gas poisoning is well known to us, most of which is caused by carbon monoxide.

PM2.5 can enter the bronchioles and alveoli directly, then enter the capillaries through the alveolar wall, and then enter the entire blood circulation system, and can not be excreted. In the short term, symptoms such as cough, difficulty breathing, and aggravation of asthma may occur. Long-term exposure will lead to decreased lung function, chronic bronchitis, non-fatal heart disease, premature death of patients with cardiopulmonary disease, and lung cancer.

Indoor burning half cigarettes PM2.5 concentration exceeds 15 times

Previously, the staff of the Harbin Anti-Treasure Office measured the change of indoor PM2.5 concentration after smoking indoors. In the conference room where the doors and windows are closed and the air conditioner is not turned on, the staff turns on the PM2.5 concentration in the instrument test room. The instrument showed that the indoor PM2.5 concentration was 15 μg/m3 before smoking, which was far less than the indoor PM2.5 concentration specified by national health standards should be no more than 75 μg/m3. When the staff ignited the cigarette about 2 meters away from the instrument, the PM2.5 concentration displayed by the instrument instantly rose to 452 μg/m3, and the value was still rising as the cigarette burned. At half the cigarette burned, the PM2.5 concentration monitored by the instrument has risen to 943 μg/m3.

In fact, only the ignition does not suck, the cigarette is not completely burned, and if it is smoking, the PM2.5 concentration will rise even higher. After the staff inhaled a cigarette and spit it out, the instrument data immediately exploded, indicating that the value has exceeded 1200 μg/m3, which is 15 times higher than the national indoor PM2.5 concentration standard.

Indoor smoking, need to open the window for more than 16 hours

Liu Ting, deputy director of the Harbin Anti-smoking Office, said, ‘The indoor PM2.5 tiny particles are mainly from tobacco smoke. Even if only one cigarette is smoked indoors, it is necessary to open the window for more than 16 hours to restore the indoor PM2.5 concentration to The previous level.’

Even if the window is ventilated, indoor smoking will leave the problem of three-handed smoke. ‘Three-handed smoke’ refers to tobacco residues left on the surface of clothes, walls, carpets, furniture and even hair and skin after the smokers ‘swallow the clouds’. According to the study, cigarette residues can exist for days, weeks or even months, even if there are ventilation, air filtration and other devices in the home can not completely eliminate PM2.5. In the case of wind or movement, the residue will also diffuse into the air, causing the PM2.5 concentration to rise again.

How to keep the air fresh

How to keep the air fresh

commercial hepa air purifier,hepa air purifier,air purifier ozone

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.

In addition to the haze, air purifiers are also important in these situations

air purifier,home air purifier,hepa air purifier

In many people’s minds, people only need an air purifier when the fog is rampant. But in the absence of smog, is the air around us really safe and clean? This is not the case. The air purifier is not only a necessity for the autumn and winter seasons, it is equally important at other times. So in addition to the haze, what other circumstances need to use an air purifier? Let me talk about it in detail.

Family with asthma and allergic patients

We all know that patients with a history of asthma and allergies are most sensitive to airborne pollutants, especially some allergens, which will greatly aggravate the patient’s condition. In the spring and summer, due to the high temperature and humidity, we will produce a large number of allergens and pathogenic bacteria such as bacteria, viruses, pollen, etc., affecting the normal life of sensitive people. Therefore, in the spring and summer season, we need to turn on the air purifier to remove allergens and germs from the air.

Family with pets

People who have pets in their homes know that it is very troublesome to clean up the hair and feces of small animals. Not only is the trouble, the hair is easy to cause allergies, the smell of feces is more difficult, so it is necessary to prepare an air purifier. In addition, pets are animals after all, so many people carry bacteria and viruses, which is also a key point to clean up.

New home renovation family

After the renovation of the new house, the most important thing is to remove formaldehyde. However, it is slow to open the window only every day. In order to quickly remove formaldehyde, window ventilation and air purifiers are more efficient. Therefore, it is necessary to use an air purifier with a formaldehyde removal function for a home that has just completed renovation.

Closer place

Such places as basements, Internet cafes, KTV, billiard halls, etc., due to the relatively closed environment, poor air mobility and complex personnel, the air quality is quite bad, so these places need to open air purifiers all year round.

Driver who drives often

Often running on the road, closing the window is prone to lack of oxygen, and opening the window exhaust is very heavy, so it is necessary to place an air purifier inside the car. In addition, some drivers like to smoke and refresh, air purifiers can effectively remove second-hand smoke, it is recommended that drivers who drive often put a car purifier in the car.

In addition to the above circumstances, the air purifier needs to be turned on, and there are many matters needing attention in the process of using the air purifier. For example, use a purifier in a closed indoor state; when the filter is used up to the upper limit, it should be replaced in time to avoid secondary pollution; use the purifier to follow the principle of air flow, etc… If you do not use the purifier according to the rules. The more dirty the air is, the more dirty it is!

Purification Of The Air Purifier Technology

                                Purification Of The Air Purifier Technology

With the changing environment, the indoor air environment has attracted increasing attention. The air purifier is effective in improving product purity of the air, now to clear the indoor air pollution, household cleaners and air-based business. Air filter in a variety of techniques and media to give air clean and safe. Commonly used technology for purifying the air are:

Low temperature plasma technology for purification, asymmetric, low-temperature plasma asymmetric forms allows high-voltage, high frequency pulsed plasma discharge in an asymmetric electric field, so that a level in the airspace between the large number of plasma to produce a series of reactions physical, chemical and hazardous and toxic gases from live viruses, bacteria and other rapid degradation, which is a powerful anti-virus, sterilization, the smell of smoke, dust and toxic substance is formed.

Air anion is a negatively charged ion gas with sedatives, hypnotics increases, diuretic, appetite, decreased blood pressure. Negative ions can be recovered from the atmosphere of air pollutants, nitrogen oxides, produced by cigarettes and other reactive oxygen species (free radicals) to reduce excess cash reactive oxygen in the human body in the air and positively charged particles without charge after the settlement, purify the air.

Molecular complex technology, which is an internal contamination with formaldehyde, benzene, ammonia and other pollutants before lock Molecular Complex, and then through the formaldehyde scavenger composition and decomposition of complex water to formaldehyde gas and short chain material is ammonia quickly turned into an irreversible solid long-chain complex, and the decomposition of ammonia salts, sediment in the water tie a clear distinction between the issues of clean air, eliminate indoor pollution.

Ozone (activated oxygen technology), the reaction of ozone to inactivate the bacteria are always made very quickly. Effect of ozone virus first body shell viral protein coat four polypeptide chains and RNA damage, in particular the formation of protein. Phage oxidation with ozone, electron microscopy shows that their skin is divided into several parts, many of which release of RNA, interfere with its absorption into the body storage.

 

As economic and social rights, better living standards and increase public awareness of the environment, various municipal facilities, commercial buildings and residential air quality problems, drew the attention of more and more. Clean air environment, improve air quality has become an urgent desire to requirements.

How should the HEPA filter be selected?

How should the HEPA filter be selected?

HEPA filter rating
HEPA filters are classified according to the level of filtration capacity and are generally classified into G1 to H14 and other grades.
For fine particles with a diameter of 0.3 microns or more, G1-F5 does not have any filtering effect, and the filtration efficiency of F6-H14 is from 20% to 99.999997%.
F6-F8 is called medium efficiency air filter;
F9-H11 is called a sub-high efficiency filter;
H12-H13 is called a high-efficiency air filter.
H14 is called an ultra-efficient air filter.

Main components of the HEPA filter
PP type HEPA filter (polypropylene, a semi-crystalline thermoplastic)
PET type HEPA filter (material for disposable plastic products)
PP and PET composite HEPA filter
Glass fiber ultra-efficient HEPA filter (an inorganic non-metallic material with excellent performance)

PP and glass fiber HEPA filters are generally not washable. Filters based on PET or containing PET have a certain degree of water washability.
However, Xiaobian has to remind everyone: PET-based HEPA is made by melt-spraying materials such as polyester resin. Due to the worst filtration effect, it is generally applied to household appliances such as vacuum cleaners and sweeping robots that do not require high filtration accuracy. Or a large cleaning machine.

What are the advantages and disadvantages of PP, PP, and PP composite HEPA?

PP type HEPA
The PP filter element is made by hot melt entanglement of ultrafine polypropylene fibers. It is the same material as the first primary filter material meltblown PP cotton in the general water purifier, but the shape is changed. In appearance, the PP-based HEPA filter is similar to the ultra-efficient fiberglass HEPA filter. Many people in the industry can’t distinguish between the two by their appearance. When PP type HEPA is used in air purifiers, the purification efficiency is not high, up to H10 level, and it can only achieve high efficiency or sub-efficiency, which is far from the ultra-efficient filtration level.

PP composite HEPA (PP and PET)
Currently, PP type HEPA filtration on the market is inefficient and cannot meet the needs of consumers. In order to expand the market, some manufacturers process PP-type HEPA filters, so there is a PP composite HEPA filter.
PP composite HEPA actually melts a layer of PP and then melts a layer of PET so that it combines PP and PET. In fact, its main material is still PP type HEPA. After treatment, a composite electrostatic layer is formed on the surface of the PP material to form an electrostatic film. The electrostatic film generates static electricity on the HEPA, and the pollutants passing through the filter are electrostatically adsorbed. Improve the efficiency of single filter filtration.
After about 3 months, after the electrostatic layer is blown by the fan and consumed, the filtration effect of the composite filter will be greatly reduced. In the long-term use, you need to pay attention to the filter consumption and replace the filter element in time.

* Glass fiber ultra-efficient HEPA

Glass fiber is also referred to as glass fiber. The filtration precision of glass fiber HEPA is very high, and the filtration grade reaches H14. Therefore, its cost is about 3 times higher than that of the PP type HEPA filter.
Glass fiber materials are quite obvious compared to PP materials:
#Strong durability: high mechanical strength, strong wear resistance, improve the durability of the filter;
#High dust holding capacity: The filter material made of glass fiber has good elasticity, and its dust-holding capacity is often doubled compared with other chemical fiber filter materials;
The glass fiber HEPA filter has the highest filtration efficiency in all materials. The HEPA filter made of glass fiber is several times more efficient than ordinary filter media.

Little Tips:
Glass fiber materials are widely used in the fields of biopharmaceuticals, dust-free and sterile laboratories for medical systems, operating rooms, electronic semiconductors, food and beverage industrial clean rooms, and other professional environmental pollution control.

When choosing the HPEA filter element, you can refer to the above and make the corresponding choice to find the purifier for HEPA filter element suitable for your home use. The purification effect will be obvious.

Young people, we are the air purifiers that pay.

Young people, we are the air purifiers that pay.

Some people say that there is more formaldehyde and it is not necessarily leukemia. Yes, like the death of Mr. Wang, his family’s self-prosecution results, the bad review is not very optimistic, because in a similar case, the court did not support the causal relationship between formaldehyde and leukemia.

The bad judge can not be sure, it must be the death of Mr. Wang caused by formaldehyde. However, the decoration pollution of the room will have various negative effects on the human body, which is certain.

For example, formaldehyde ranks second in China’s priority list of toxic chemicals and is determined by the World Health Organization to be a carcinogenic and teratogenic substance. It can induce nuclear mutations in the nucleus and interfere with normal DNA activity, which can cause neonatal chromosomal abnormalities and leukemia. Long-term low concentrations of formaldehyde can also cause chronic respiratory diseases, causing nasopharyngeal cancer, colon cancer, brain tumors and the like.

IARC International Agency for Research on Cancer believes
Formaldehyde can cause a high risk of cancer and leukemia

Moreover, not only formaldehyde, but also aromatic hydrocarbons, that is, volatiles such as benzene and toluene, are highly volatile in the 3-6 months after the renovation, and the academic literature clearly indicates that it will cause leukopenia. , thrombocytopenia, can cause acute myeloid leukemia. To say that formaldehyde is still a bit controversial, this is nailed on the board.

There is an old saying in the decoration industry, “No aldehyde is not glued, no benzene is not lacquered”, freely used in the apartment’s table, the wardrobe is a composite sheet, which contains a lot of industrial glue, furniture surface and a variety of metal lacquer wood paint.

Free sample room

It is safe to say that they use e1 grade plates and are qualified. These plates are used as the whole plate at the factory and have been treated in the surrounding area. Only a small amount of free formaldehyde is leaked out during the test, which is naturally qualified.

However, once the furniture is made, there will be formaldehyde leakage on the cutting surface. During the aging process of the glue, the free formaldehyde will continue to emanate, and the evaporation period can be up to 15 years. At this time, you will pass the test, who believes?

China has a low requirement for the emission value of formaldehyde. The “Limited Quantity of Hazardous Substances in Wood Furniture for Interior Decoration Materials” stipulates that the amount of formaldehyde released in wooden furniture should be less than or equal to 1.5mg/L, and the requirements of the United States, the European Union, and other countries. It is much stricter than ours.

In addition, under the circumstance of capital, long-term rental apartments rushed all the way. In order to quickly withdraw funds, the industry’s default unspoken rule is 10 days of renovation (non-blank room), rent out within 7 days, and no time for pollutants to evaporate. It is strange to not exceed the standard.

There are a lot of houses in big cities that are packed in long-term rental apartments such as eggshells, and such long-term rental apartments are indeed better than general housing in terms of facilities and decoration styles, so they are very popular among young people.

Air Purifier, are you right?

Air Purifier, are you right?

In recent years, with the outbreak of environmental air pollution in China, people are paying more and more attention to the air quality of their environment. Bacteria, viruses, odors, chemical gases, etc. suspended in the air can threaten human health.

In particular, new homes that have just been renovated are even more harmful to vulnerable people such as the elderly, children, and pregnant women. As the most effective product to improve air quality, air purifiers have become the standard for many families.

At present, there are many kinds of air purifiers on the market. But how do you really choose a high-performance, high-quality air purifier?

At the just-concluded Olansi “Winning the Future – Healthy Breathing into the First Anniversary of Wanjia and New Products”, how to choose an air purifier, a professor at Shanghai Jiao Tong University, an expert in air purification industry, “the first person in China’s air purification”, China Professor Wu Jixiang, an expert in the Indoor Environmental Purification Management Committee, said that a truly effective air purifier = high CADR value + high CCM value + high energy efficiency value + low noise.

Professor Wu Jixiang, the first person in China’s air purification, explained at the Olansi Air Purifier New Product Launch Conference
“Three highs and one low”, the four indicators of the Olansi air purifier are all better than the new international highest standards.

What kind of effects can these indicators play in daily use?
CADR value: air purification capacity of up to 800m3 / h, the industry-leading, air in 15 square meters of space, only 2 minutes and 45 seconds, can be completely purified. Easy to get all kinds of apartment types, a home office is suitable!
CCM value: It represents the purification ability of pollutants. The continuous purification ability of the Olansi Air Purifier is higher than the highest international standard and has good performance.
Energy efficiency rating: It represents the clean volume produced by one-degree electricity consumption. It is a measure of the energy consumption of an empty net. The higher the grade, the better the effect. The energy efficiency rating of the Olansi air purifier is higher than the highest international standard, and it is more energy-efficient to use. Electricity.
Noise: The noise in the maximum wind speed mode is only 68dB, which is lower than the ambient sound in the discussion. The noise in the sleep mode is only 34dB, which is lower than the ambient sound of the baby’s sleep.

In addition, the Olansi air purifier also has negative ion purification, 2-layer filter 3 mesh and 4 heavy filtrations, precision sensor, low energy consumption, long life, 360 degree no dead angle purification, thoughtful design, worry-free and so on…

How to use the air purifier correctly? How long is it suitable for each day?

In the air-conditioned rooms in the summer, we often feel that the air is cloudy and occasionally feels chest tightness and dizziness. This is because the contaminants in the confined space are increasing, and the oxygen is gradually consumed by the human body, so the above conditions occur. Adding to the organic pollutants volatilized by interior decoration materials and furniture, bacteria floating in the air aggravate this situation.

The health of the family is threatened by the quality of the polluted air, and the function of the air purifier to clean the air is a good solution to this problem. How long does it take to keep the indoor air at a healthy level?

First, the living scene

Newly renovated houses should be opened as much as possible before the check-in. Because formaldehyde is a continuous release of decorative pollutants, the newly-renovated houses are released in large quantities, and the release of formaldehyde slowly decreases over time. After the check-in, if you can’t open the window, you should rely on the air purifier. At this time, the use of time should be extended appropriately, at least 4 hours per day. If there is an obvious smell in the room, it is recommended to open for more than 8 hours.

Second, the local environment

Because of the different geographical environments, the sources of pollution are different, and the air pollutant content varies from place to place. If the ambient air quality is excellent or good, you can choose to use it one hour before going to bed. But the most important thing about sleep is quietness, and mature products such as Senchen and Philips are doing very well in this respect. When adjusting to the small windshield, they only hear their breathing sounds quiet, and suggest that the machine should be placed away. The farther bed position reduces the risk of radiation.

Third, the weather conditions and space size

If the air quality of the day is not very good, depending on the size of the space, the living space is generally 4-8 hours. If space is large, it is delayed. On the other day, the concentration of pollutants will be higher in the morning and evening. It is recommended that air purifiers should also be used during these two periods.

In the rainy days, the dust in the rain and the suspended matter in the air will also drop. The air quality at this time is relatively good. However, in the “fine rain” weather, when you need to close the doors and windows, you should also use an air purifier to remove bacteria from the room.
