Today we want to share with consumers on Air Quality Index.

According to the air quality testing standard of China Environmental Protection Network, the classification of pm2.5 index is explained in detail:

1. excellent, index>=50

Under such a pm2.5 index, there is no pollution in the environment and there will be no impact on everyone’s health, and everyone can travel normally.

2. good, index 50 -100

Such a screen pm2.5 index is acceptable to everyone, and it will not cause great harm to everyone’s body.. However, some people who are particularly sensitive to certain pollution should reduce their travel, otherwise it will lead to the respiratory tract of these sensitive people. Discomfort, in severe cases, dizziness, vomiting and other discomfort symptoms may occur.

3. light pollution index 100-150

Sensitive people will increase their discomfort, and healthy people will also be stimulated. Therefore, the elderly, children, sensitive people, and people with heart and respiratory diseases should reduce their time outdoors.

4. Moderate pollution, index 150-200

In this index state, it will further aggravate the discomfort symptoms of susceptible people, and it will have a certain impact on people with heart disease and respiratory diseases. Children, the elderly, and those with heart or respiratory diseases should minimize their outdoor exercise time, and the general population should also reduce outdoor travel.

5. Severe pollution index 200-300

In this index state, the discomfort of people with heart disease, lung disease, and respiratory system disease will increase, and exercise endurance and resistance will decrease. It is recommended that children and the elderly, heart disease patients and patients with respiratory diseases try their best Avoid outdoor travel. Healthy people should also reduce outdoor sports.

6. the severe pollution index is greater than 300

Under this index, the endurance of healthy people will also decrease, and it will be accompanied by discomfort. Therefore, children, the elderly, patients with heart disease and respiratory system patients should stop outdoor exercise, and healthy people should avoid outdoor exercise. People living under this index should prevent the occurrence of each disease in advance.

Most of the air purifiers are with air quality indicator.

Is your air purifier compliant? Five risk points were found in quality and safety risk monitoring

In order to prevent smog, many people have bought air purifiers in their homes, and some homes have more than one. Sales of air purifiers in Europe reached 5.2 million units last year and are expected to double this year, according to statistics. Air purifiers will become the fifth largest household appliance after color TVS, air conditioners, refrigerators and washing machines. There are nearly a thousand brands in this huge market, but what about their quality?

Air Purifier A5 _页面_01

Today, the provincial Quality supervision Bureau released the air purifier product quality and safety risk monitoring, from the market to buy extraction of 15 enterprises produced by the air purifier testing found that there are only three standards.

Liu Mengmeng, an engineer at the home product testing center of the Provincial Quality Inspection Institute, told reporters: “The risk monitoring, there is a widespread phenomenon of exaggerated publicity, mainly in noise, clean energy efficiency, and the sterilizing rate of these three indicators.”

K09b_03

The risk points found are mainly particulate matter clean air quantity, formaldehyde purification energy efficiency, particulate matter purification energy efficiency, antibacterial rate and noise. Among them, there were 5 air purifiers with antibacterial function, but the coincidence rate of antibacterial rate was 0%.

Liu Mengmeng introduced to reporters: “Air purifier products there is a very important core indicators is the cumulative amount of clean, we compared the mesh of air purifier ChengHaiMian, purification increases with time, the adsorption of sponge pollution increase, so this time we will regularly change the sponge, so clean air quantity, namely CCM value is also means the greater the adsorption capacity of the sponge, It also means that the air purifier filters last longer and are replaced less often.”

Some air purifiers excessively promote the purification effect, especially the virtual standard of clean air quantity, resulting in consumers failed to replace the filter in time, not only can not effectively purify THE PM2.5 particles, formaldehyde, bacteria and other indoor, but also will produce secondary pollution, harmful to human health.

At present, air purifier products in addition to the existence of exaggerated publicity of the purification effect of the problem, the provincial quality supervision department also found that some air purifier air outlet size is too large, children’s fingers can be inserted, there is a potential safety hazard of electric shock or stir fingers.

Household air purifier is mainly based on filter purification, which is to pump air into the machine with a fan and filter the pollutants in the air through the built-in filter.

Olansi Healthcare Co.Ltd. Air purifier manager Joanna illustrates the working principle of air purifier to the reporter, she said: “we are now on to make a pollution environment, then we use the cell phone QPP, to control our purifier boot, about 10 seconds, we can see that the smoke has been to remove completely.”

At present, the particle purification technology is relatively mature, can well remove PM2.5 and other pollution particles in the air.

“But in the risk monitoring, we found some problems with the air purifier. The gap between the air purifiers is too large, similar to that of children or adults with small hands, which may encounter live parts or moving parts that day,” said Joanna.

 

Is air purifier just for haze? What are the functions of air purifier?

Some people say that in China, 99% of the hot air purification industry market is due to haze (commonly known as PM2.5). In fact, otherwise, in addition to the air purifier can purify haze and PM2.5, it can also purify indoor formaldehyde, second-hand smoke, odor, dust and other harmful gases.Air Purifier A5 _页面_01
The domestic air purifier is just in its infancy, but the foreign air purifier market, especially in Europe, Japan, the United States and other places, has been very mature. In these countries and regions, although the outdoor air quality is far better than that in China, there is no haze, but the popularity rate of air purifier is very high, and even legislation is mandatory to install. So you think the air purifier is just for haze. Is that true? The following might as well followOlansi Healthcare,a professiona air purifier manufacterer , to learn more about the function of air purifier.

Generally speaking, to solve the problem of indoor air pollution, window ventilation is a good way, but once the window is opened, it will lead to the loss of indoor cold and hot energy, damage the overall insulation system of the building, and make the outdoor dust and noise enter the room. Therefore, the contradiction of opening and closing windows has been unable to be fundamentally solved. It is for this reason that people begin to deeply study and explore the impact of indoor air quality on human health, pollutants and their sources, as well as feasible solutions. Finally, in Europe, where economy, science and technology are developed and quality of life is emphasized, it appears.

幻灯片2
The air purifier is a continuous and controllable ventilation mode. The replacement of air purifier can be completely controlled through the fan and air flow control system with good performance. This technology has little effect on the indoor temperature. Under the premise of no windows, the indoor dirty air is continuously filtered 24 hours a day to purify fresh air, and the air volume is effectively controlled. In the 1970s, more than 90% of newly built houses in Spain were equipped with air purifiers; In 1989, ASHRAE of the United States formulated the “code for indoor air quality ventilation”; In Germany, the residential ventilation system has become an integral part of the building; In 2000, air purification has become a law in the whole European Union.
There are several reasons for the high purchase rate of their air purifiers: the economic and material basis of life, the basic layout of the house, the outdoor noise, the use of indoor air conditioning, and the living habits of residents. With the sustained and stable development of China’s economy, in many aspects of material basis and health concept, the gap between us and the residents of these countries and regions is getting smaller and smaller. Coupled with the popularity of air conditioning, the concept of window ventilation will gradually be replaced by the use of air purifier.

Main advantages of air purifier:
1) You can enjoy the fresh air of nature without opening windows;
2) Avoid “air conditioning disease”;
3) Avoid mildew of indoor furniture and clothing;
4) Remove the harmful gas released for a long time after interior decoration, which is beneficial to human health;
5) Effectively remove all kinds of indoor bacteria and viruses;
6) Super quiet;
7) Reduce indoor carbon dioxide concentration.

Therefore, air purifier is not a product of haze. Even without haze, China’s air purifier market will develop rapidly.

Three Methods for Measuring The Concentration of Hydrogen-rich Water

Founded in Guangzhou in 2009, Olansi Healthcare Co Ltd is a professional manufacturer on hydrogen water generators,air purifiers, disinfectant liquid generators, water purifiers, beauty products etc. Healthcare products. Olansi covers more than 60000 square meters, owns more than 350 staffs, with turnover US$ 100 million in 2020. Olansi has been serving worldwide famous brand like Haier, Midea, TATA group etc. for a long time and have good partnership with worldwide customers.

When choosing hydrogen aquatic products, hydrogen concentration is the first consideration. Because the higher the hydrogen concentration, the more hydrogen content, the more obvious the effect.

However, the concentration of hydrogen aquatic products on the market is also varied, which poses a selection problem for consumers who do not know much about it.

Take the numerous hydrogen-rich water cups as an example.

The hydrogen concentration of the hydrogen-rich water cup is mainly divided into two categories.

The first category is the hydrogen concentration below 1600ppb. This part accounts for the vast majority, and it is estimated that it should account for about 95% of the market. The second category is that the hydrogen concentration is above 1600ppb, and some even reach above 5000ppb. This part of the product does not account for much of the market, it should be around 2%. Probably because of high production costs and high sales pressure, only a few manufacturers are doing it.

For consumers, in addition to looking at the hydrogen concentration value marked by the merchant, they still murmur in their hearts. Is it possible to reach the advertised concentration? How did these hydrogen concentration values ​​come from? Here is a popularization for everyone.

There are currently three main methods for measuring hydrogen concentration:

The first type: titrant test The second type: hydrogen test pen test (oxidation-reduction potential pen) The third type: meteorological chromatographic analysis

These three methods have their own advantages and disadvantages. But it can reflect the hydrogen content from a certain angle.

 

The first method is the titrant test method

The composition of the titration solution is a mixture of methylene blue and nano-platinum colloid.

The measurement method is to judge the hydrogen concentration by the number of drops of reagent in 6 ml of water. One drop represents 100ppb. If it reaches 20 drops, it is 2000ppb.

The judgment method is that if there is hydrogen in the water, the titration liquid will change from blue to transparent after it is dropped in. Keep dropping until the drop no longer becomes transparent, indicating that the hydrogen in the water has reacted with the titrant. In this way, the hydrogen content in the water can be judged based on the total number of drops.

The advantages of this method are:

  1. The cost is low, almost every consumer can afford it, and the operation is relatively simple.
  2. The hydrogen concentration value above 1600ppb can be quickly measured. Generally speaking, the hydrogen concentration above 1600ppb needs to be tested with a titrant.

The disadvantages of this method are:

  1. If the hydrogen concentration is lower than 300ppb, it may not change color. People mistakenly believe that there is no hydrogen in the water. The reason is that if it is less than 300ppb, because the test requires only 6ml of hydrogen water, which is very small, and the hydrogen is very volatile, so if the hydrogen reacts with the titrant, the hydrogen may have been volatilized.
  2. There are many error factors. Everyone’s dripping speed and the size of the drip are different, which will affect the final value. If the dripping is fast and the dripping ball is small, the measured value will be higher. The dripping is slow and the dripping ball is large, so the measured value must be a little bit smaller.

 

The second type: hydrogen test pen test

The hydrogen measuring pen is actually a redox potential pen. It is based on the value of the oxidation-reduction potential in the water to convert the hydrogen concentration value.

The conversion formula is currently the hydrogen concentration value obtained by the negative potential value × 2.5 in the industry.

For example, if the negative potential in the water is -200mv, then 200×2.5=500. From this, it can be judged that the hydrogen concentration in the water is 500ppb, and the hydrogen measuring pen will display 500. If the negative potential in the water is -600mv, then 600×2.5= 1500 Hydrogen measuring pen will display 1500.

Hydrogen can change the potential value of water. As long as there is hydrogen in the water, it can turn the water into a negative potential.

However, the hydrogen content and the negative potential value do not necessarily have a positive proportional relationship. It is not that the more hydrogen content, the negative potential value will continue to decrease.

The negative potential value in hydrogen water is generally around -400mv~-600mv, so the value converted by the hydrogen measuring pen is around 1000-1500ppb. This is the fundamental reason why most of the hydrogen water measured by the hydrogen measuring pen does not exceed 1600ppb. The limit of the negative potential value in water is -1200mv, then 1200×2.5=3000. Therefore, the second-generation hydrogen measuring pen in Japan claims to be able to display up to 3000ppb. But almost no one can measure the value of 3000. Because the negative potential value in water is almost impossible to be as low as -1200mv. Therefore, the hydrogen measuring pen will never detect a hydrogen concentration above 3000.

Advantages of this method:

  1. High sensitivity, quick output value. Because it is calculated by potential. 2. Ultra-low hydrogen concentration value below 300ppb can be measured.

Disadvantages of this method:

  1. The price is high. A Japanese original hydrogen measuring pen is priced at more than 2,000 yuan, which is much more expensive than a hydrogen-rich cup. For ordinary consumers, it is obviously not cost-effective to test the hydrogen concentration. 2. It is difficult to save. The tip of the hydrogen measuring pen requires high maintenance and requires a special solution for regular cleaning and maintenance. For ordinary consumers, it is difficult and unnecessary. 3. The measurement interval is limited because the hydrogen concentration conversion is based on the negative potential value, and it cannot truly reflect the value of the hydrogen content in the water. For the hydrogen content under normal temperature and pressure, the accuracy is still relatively high, but for high-pressure hydrogen production, the hydrogen measuring pen will not work. Especially for hydrogen concentrations higher than 2000ppb, the hydrogen measuring pen is almost useless. For example, a 4000ppb hydrogen water, if its negative potential value is -400mv, the value measured by the hydrogen pen is only 1000ppb, which is 3000ppb different from the actual value.

High hydrogen concentration does not mean high negative potential

There is no necessary relationship between hydrogen concentration and negative potential.

If there is hydrogen in the water, the water will have a negative potential. But it is not that the more hydrogen, the higher the negative potential value of water. Therefore, the method of converting the hydrogen concentration by the negative potential value is still unreliable under certain conditions.

Does hydrogen water over 5000ppb really exist?

Nothing in the world is absolute. When the surrounding environment changes, oneself will also change accordingly.

The hydrogen concentration is the same. The external environment is different, and the hydrogen concentration is also different.

The general scientific community believes that the solubility of hydrogen in water is difficult to exceed 1600 ppb under normal temperature and pressure.

Most of the hydrogen-rich cups also produce hydrogen at room temperature and pressure. In the case of multiple hydrogen production, the hydrogen concentration may reach about 2000ppb, but it is difficult to increase it.

But it’s different in a high-pressure environment. Any gas, under high pressure environment, can improve the solubility in water.

Hydrogen is no exception.

The higher the pressure and the longer the time, the more hydrogen will be dissolved.

Not to mention 5000ppb, Japan and Taiwan have even produced 20000ppb hydrogen water.

This is like a passenger car. Under normal circumstances, it carries 20 people, but if people are forced into it, 50 people may be loaded.

Therefore, don’t think that the hydrogen content higher than 5000ppb is bragged by the merchants, which can be produced by high pressure.

 

The third type: gas chromatography

This should be regarded as the most accurate measurement method at present. But it can only be done in the laboratory.

It is difficult for ordinary individuals or factories to do this. So I won’t introduce too much here.

So to sum up, for people in the hydrogen industry, if you want to measure hydrogen concentration, it is best to use a hydrogen-rich pen, which is convenient and convenient. Although the titrant is cheap, the frequency of use is too high and the cost is not low.

Indoor Air Purifier for 2022, why choose OLANSI?

How to choose an air purifier? This question has always been a hot topic. When choosing an air purifier, the first thing we should pay attention to is that it must be targeted, whether it is used to remove PM2.5 and formaldehyde, or remove odor or remove allergens, according to the actual demand targeted selection of products, to spend money wisely is correct.

Pollen

So for example, when we just changed to a new house or just bought a few new pieces of furniture, we need an air purifier that can remove formaldehyde; for pets in the house, pets have a strong odor in summer, and an air purifier that removes odor must be prepared. in the blooming season, allergen-removing air purifiers have become a necessity again, so do we have to buy three different air purification products to remove the three air pollutants above? Not necessarily, OLANSI launched one The core-replacement air purifier allows users to freely choose the filter element to solve various common air problems such as formaldehyde, peculiar smell and allergens in a targeted manner.

 

Is OLANSI air purifier easy to use? Formaldehyde filter, three steps to remove decoration pollution

 

The formaldehyde filter of the OLANSI core-replacement air purifier uses three steps to efficiently remove decoration pollution. The first step is to use the net aldehyde component specially added to the filter to carry out chemical decomposition; the second step is to pass through the activated carbon with abundant pores. To capture the decoration pollutants such as formaldehyde and TVOC in the air; the third step is to prevent escape. The filter is specially added with solid aldehyde components, which can effectively improve the stability of activated carbon adsorption, firmly adsorb formaldehyde and other decoration pollutants to prevent escape.

 

Is the OLANSI air purifier easy to use? The allergen filter quickly locks allergenic ingredients

PET

As soon as spring comes with the revival of all things, the flowers are in full bloom, and it is allergic rhinitis. Once the rhinitis is committed, the tears will flow. It is not a problem to draw a paper after two days. When you go out, you can only wear a mask, and you can turn on the OLANSI air purifier equipped with an allergen filter at home. After testing by the China Household Electrical Appliances Research Institute in accordance with the “Anti-allergen Performance Test Method”, this allergen suppression filter is in The purification rate of dust mites can reach more than 90% within one hour. This is because this filter element is added with sensitizing ingredients extracted from natural large-leaf trees. It can be inhibited by locking the sensitizing ingredients of common allergens and making them inactive. The effect of allergens.

 

Is OLANSI air purifier easy to use? Pet filter, targeted destruction of odor molecules

 

Friends who have kept pets at home know that the area around dog kennels and litter boxes can be said to be the hardest-hit area with peculiar smells, especially in the hot and humid summer, the smell is even better. The pet filter of the OLANSI air purifier can solve this problem well. Its key deodorization technology can directionally destroy the chemical bonds of odor molecules. In addition to effectively removing the odor generated by pet metabolism, it can also effectively remove the odor from the pet’s metabolism. The smell of corruption, the peculiar smell from the bathroom and other common peculiar smells in the family environment can be effectively removed.

4.26

The working principle of an air purifier is very similar to that of human lungs. It first sucks in gas, then performs adsorption and filtration treatment inside, and finally releases the purified gas into the environment. So is the air purifier easy to use? To a large extent The above depends on the internal filter element of the air purifier. Only one air purifier is needed to solve the problem of household air pollution in a targeted and on-demand manner. In addition to the advantages of free choice of filter elements, the OLANSI air purifier also has a very intelligent pollution source sensing system to monitor the air quality of the home in real time to protect the health of the family.

What is water purifier?

Founded in Guangzhou in 2009, Olansi Healthcare Co Ltd is a professional manufacturer on water purifiers, hydrogen water generators,air purifiers, disinfectant liquid generators, beauty products etc. Healthcare products. Olansi covers more than 60000 square meters, owns more than 350 staffs, with turnover US$ 100 million in 2020. Olansi has been serving worldwide famous brand like Haier, Midea, TATA group etc. for a long time and have good partnership with worldwide customers.

Water purifiers, also called water purifiers and water purifiers, are water treatment equipment that perform deep filtration and purification of water according to the requirements for water use. Water purifiers usually refer to small purifiers used in households.

The core of its technology is the filter membrane in the filter element device. The main technology comes from three types: ultrafiltration membrane, RO reverse osmosis membrane, and nanofiltration membrane. The role is to purify harmful substances in water and impurities in the water. Originated in the early 1880. Originated in London, England. Water purification technology. Ceramic filtration. Ultrafiltration membrane. Activated carbon. Reverse osmosis water purification classification. Purified water machine, ultrafiltration machine and microfiltration machine. Commercial water purifier Medical water purifier

Water purifiers can be divided into two categories according to pipeline design grades: progressively tightening water purifiers and self-cleaning water purifiers. The traditional water purifier is a gradually tightening water purifier. Its internal pipeline is designed with a filter element that is loose before and then tightened. It is composed of PP melt blown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and activated carbon at the rear. It is composed of these 5 levels in turn end to end. The retentate is deposited inside the filter element and needs to be manually disassembled and washed regularly to ensure the normal operation of the machine. The other is a more advanced self-cleaning water purifier. Two channels are designed in the machine and a washing water channel is added. When the washing water used as ordinary domestic water passes through the channel, it affects the filter element in the machine, especially the raw water of the membrane filter element. The side plays the role of flushing to achieve self-cleaning, and uses the water that flows away from the head and tail at the moment of opening and closing the washing faucet to discharge the trapped dirt in time and quickly. This structure is designed reasonably and saves labor. The trouble of dismantling and washing avoids re-pollution of the organization itself and at the same time reduces energy consumption costs.

But consumers are reminded to recognize that self-cleaning water purifiers are different from the automatic sewage water purifiers, computer automatic flushing water purifiers and automatic backwashing water purifiers seen on the market. The former is self-cleaning, that is, It is said that all filter elements inside the machine have a certain self-cleaning function; the latter only washes one of the filter elements instead of the whole machine. In layman’s terms, the self-cleaning water purifier is equivalent to a garbage disposer installed in the pipeline, and the dirt is cleaned out at any time without staying in the machine. The traditional non-self-cleaning water purifier is equivalent to putting multiple trash cans in the room, and the dirt is usually temporarily stored in the machine, so it needs to be drained, removed and washed regularly, and the filter element needs to be replaced frequently.

The function of the water purifier is to remove floating substances, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, etc. in the water. It has high-precision filtration technology, and the five-stage filtration technology of household water purifiers The first level is the filter element, also known as PP cotton filter element (PPF), the second level is granular activated carbon (UDF) filter element, the third level is precision compressed activated carbon (CTO) filter element, and the fourth level is reverse osmosis membrane or ultrafiltration membrane. The fifth level is the post activated carbon (small T33). The water purifier is not only suitable for areas with serious tap water pollution, but also can filter the residual chlorine in conventional tap water, and at the same time can improve the taste of water.

The first level: PP cotton: remove all kinds of visible objects/dust and impurities in tap water.

The second and third stage: pre-activated carbon: part of the third stage of low-profile water purifier is also PP cotton, carbon to remove chlorine and organic impurities. It can also absorb the peculiar smell, color and smell produced by organic compounds in the water.

The fourth level: ultrafiltration or reverse osmosis membrane: the membrane can remove bacteria, viruses, spores and other substances in the water.

The fifth level: post activated carbon device: to further improve the taste and remove peculiar smell.

Most of the water purifiers adopt a progressive structure method based on the principle of screen-blocking filtration, which is composed of multi-stage filter elements connected in series, and the filter elements are arranged in order from low to high precision to realize multi-stage filter elements to share and intercept the dirt, thereby reducing filter element clogging And the number of manual drainage, disassembly and washing, and extension of the replacement cycle of the filter element. There is also a new design idea that applies the principle of quality distribution and self-cleaning structure. Its design idea is no longer to provide as much space as possible for collecting dirt, but to adopt the principle of quality separation to separate a small amount of dirt. Part of the clean water, and at the same time, let the raw water circulate as much as possible so that the pollutants can be taken away with the water in time, so that the water does not rot. In this way, purified water is obtained, and it will not or be difficult to deposit dirt in the machine, avoid secondary pollution and greatly reduce filter element loss, and the water quality is better, safer, and energy-saving and low-carbon. This new principle self-cleaning water purifier won the Gold Award at the 7th International Exhibition of Inventions. It has a one-in-two-out structure. It improves the impurity concentration of the raw water in the machine due to the structural defects of one in and one out of the traditional water purifier. The more it accumulates, the higher it eventually becomes sewage. Therefore, the concept of self-cleaning water purifiers without sewage and sewage water purifiers is replaced by washing water. With the improvement of living standards, the popularity of water purifiers will become wider and wider, and new technology products are better meeting people’s needs.

How does an air purifier ensure indoor air quality 2022

Home is a warm harbor, not just a residence. The Chinese have a profound concept of home. However, what we think of as a beautiful home hides its evils and threatens the respiratory health of family members at all times. You may have noticed physical discomfort, but you don’t know where the problem is? This is caused by indoor air pollution.

K15B_08

Four major indoor pollution sources

 

1. Formaldehyde pollution caused by new house decoration

 

A friend asked, can formaldehyde pollution be avoided? In fact, formaldehyde pollution is difficult to avoid. Even if environmentally friendly building materials are used, more or less formaldehyde will be released. The main source of formaldehyde release is the glue component in furniture wood panels, and the release cycle of formaldehyde is as long as 10 years. With the increase of temperature, the release is intensified, which is the main culprit of indoor air pollution.

 

2, second-hand smoke pollution

 

There will always be men or relatives and friends who like to smoke at home. When they enjoy the pleasure of smoking, they are buried by their friends. There are more than 4000 kinds of harmful chemical substances and dozens of carcinogens in second-hand smoke, which exist in the air, dust and the surface of objects for a long time, and they are not easy to dissipate. Non-smokers often “enjoy” the bombardment of multiple smokers, with a long exposure time and serious injury, especially for young people.

 

3, smog PM2.5

 

In a twinkling of an eye, autumn and winter have come, and it is another season when smog begins to ramp up. Haze is very harmful to human health. Because the fine powdery floating particles in the haze are generally below 0.01 microns in diameter, they can directly enter the bronchi and even the lungs through the respiratory system. Therefore, the biggest impact of haze is the human respiratory system, and the diseases caused are mainly concentrated in respiratory diseases, cerebrovascular diseases, nasal inflammation and other diseases.

 

4, pollen, pet hair, dust mites, bacteria and virus contamination

 

There are more and more families with pets. When acting as their shit shovel officer, they must also do a good job in solving the problems that are prone to allergies. In the summer air-conditioned room, the closed space makes the indoor air quality drop sharply. At the same time, there is also concern about the invasion of pollutants in the air conditioner.

 

How to solve these invisible and intangible pollution? Maybe an air purifier can help you solve these troubles and make your home a safe and warm arm. What kind of ability does an air purifier have to make indoor air healthy?

6

 

This is to find the answer from the principle of air purifier purification

 

Most of the air purifiers on the market use filter filters to purify, mainly composed of motors, fans, air filters, and intelligent monitoring systems. Some models of machines are also equipped with humidifying water tanks and auxiliary purification devices. Among them, the air filter is the core component of the air purifier, which mainly filters out pollutants in the air sent into the room, thereby purifying the air.

 

Of course, different air purifiers use different technologies, including adsorption technology, HEPA high efficiency filtration technology, negative (positive) ion technology, catalytic technology and other technologies. Users should pay more attention when purchasing air purifiers. Do not blindly use technology as the main reference object, but choose air purifiers based on their own needs.

An article tells you where and who needs air purifiers the most

Air purifiers are used in the home, medical and industrial fields. In the home field, single-machine household air purifiers are the mainstream products in the market. The main function is to remove particulate matter in the air, including allergens, indoor PM2.5, etc. At the same time, it can also solve the indoor, underground space, car air pollution caused by decoration or other reasons. Because the release of air pollutants in a relatively closed space has the characteristics of persistence and uncertainty, the use of air purifier to purify indoor air is one of the internationally recognized methods to improve indoor air quality.

Applicable place:

1. A newly decorated or renovated residence.

2. The residence of the elderly, children, pregnant women and newborns.

3. Residence for people with asthma, allergic rhinitis and pollen allergy.

4. Accommodation for keeping pets and livestock.

5. Residences that are more closed or affected by second-hand smoke.

6. Hotels and public places.

7. Willing to be the residence of the high quality of life.

8, hospitals, reduce infection, stop the spread of disease.

Applicable people:

1, pregnant women: pregnant women in the room with serious air pollution will feel general discomfort, dizziness, sweating, dry smoke, dry tongue, chest tightness to vomit and other symptoms, which have adverse effects on the development of the fetus. Pregnant women who breathe fresh air are three times as likely to give birth to a child with heart disease.

2, children: children’s body is developing, the immune system is relatively fragile, vulnerable to indoor air pollution harm, leading to decreased immunity, physical growth retardation, induced blood diseases, increase the incidence of children asthma, so that children’s intelligence is greatly reduced.

 

3, office gens: in the high-grade office building when working an enviable occupation. But in the constant temperature sealed air quality is not good environment, easy to lead to dizziness, chest tightness, fatigue, emotional ups and downs and other uncomfortable symptoms, affect work efficiency, cause a variety of diseases, serious can also be carcinogenic.

4, the elderly: the elderly body function decline, often a variety of chronic diseases. Air pollution not only causes the elderly tracheitis, pharyngitis, pneumonia and other respiratory diseases. It can also induce hypertension, heart disease, cerebral haemorrhage and other cardiovascular diseases.

5. Respiratory disease patients: long-term life in polluted air will cause decreased respiratory function and aggravation of respiratory symptoms, especially rhinitis, chronic bronchitis, bronchial asthma, emphysema and other diseases. Through the breathing of pure air to achieve auxiliary and radical therapeutic effect.

6. Driver: The car is starved of oxygen and the exhaust pollution is serious.

What reason do I need to buy an air purifier in 2021-2022?

Is there serious air pollution in the cities in which they live? Maybe some people live in areas where air pollution is not so severe, and they are not so vigilant and feel harmful to air pollution, but in fact, air pollution is everywhere, and China’s reforms are nearly four. Over the past ten years, my country’s economic development has undergone earth-shaking changes, but at the same time it has inevitably brought environmental pollution, including air pollution, water pollution, and life pollution. In the current, polluted environment, the use of air purifiers is imminent. Not only outdoor air pollution, but indoor air pollution has to be taken seriously. So what is the reason for using an air purifier?

1. Removal of formaldehyde in the decoration room

 

If the smog still bullies people by region and season, formaldehyde is relatively fair-rural cities are treated the same, winter and summer are not distinguished, as long as you decorate the house, formaldehyde will follow. This year, who doesn’t have one or two newly renovated houses?

 

The hazards of formaldehyde, every company that makes air purifiers backs up, but when it comes to thorough purification, not every company understands it.

 

Friends who have done a little research on air purifiers know that most of the filter elements on the market that purify formaldehyde are adsorbed by activated carbon. This method is really effective, especially in the initial stage of purification. However, as time goes by, the adsorption of activated carbon is gradually saturated, and it seems to be incapable of continuing to remove formaldehyde. Even when the temperature rises, the adsorbed formaldehyde is released again, causing secondary pollution. If you don’t want to be hurt by the enemy, the best way is not to lock it up, but to complete humane extinction. It is the same to prevent secondary pollution of formaldehyde.

 

At present, there are very few purifiers capable of “humane extinction” of formaldehyde in China. The cold catalyst decomposition technology of Olandes air purifier can quickly decompose formaldehyde into carbon dioxide and water that are harmless to the human body under normal temperature and pressure. Without any secondary pollution.

2. Outdoor atmospheric environment

 

As early as 2008, the Ministry of Environmental Protection of my country issued an announcement showing that among the 519 cities in my country that reported air quality data, only 21 cities reached the first level, accounting for only 4% of the total number.

 

Three, ensure healthy breathing

 

Two-thirds of a person’s life is spent indoors. According to surveys, the indoor air pollution rate is 5-10 times that of the outdoor. The indoor chemical pollutants such as second-hand smoke, formaldehyde, and radon gas , Benzene series, ozone and peculiar smell, indoor hygiene products may produce carbon dioxide, carbon tetrachloride, dibenzene, toluene, xylene and other toxic substances, which are very harmful to the human body. Long-term exposure to indoor air pollution can easily lead to various diseases such as respiratory diseases, lung cancer, and atherosclerosis.

 

The above three reasons tell you that it is impossible not to use an air purifier. The multi-layer filtration system of the Olansi air purifier can filter, adsorb and decompose the indoor air pollutants layer by layer to achieve a cleanliness of more than 99.97%. .

HEPA air purifier can significantly reduce airborne COVID-19 particles

As COVID-19 restrictions ease nationwide and more people host indoor gatherings, investing in a high efficiency particulate air (HEPA) purifier might not be a bad idea, says a University of Cincinnati College of Medicine researcher.

Several published studies evaluating aerosols and submicron particles similar in size to the SARS-CoV-2 virion have shown that portable HEPA purifiers are able to significantly reduce airborne COVID-19 particles, says Ahmad Sedaghat, MD, PhD, director of the UC Division of Rhinology, Allergy and Anterior Skull Base Surgery.

Sedaghat identified the medical literature showing published studies on the effectiveness of HEPA purifiers. His review is available online in the scholarly journal of the American Academy of Otolaryngology-Head and Neck Surgery Foundation.

Air purifiers could benefit hospitals and physician offices where aerosol-generating procedures occur, but they are also useful for reducing COVID transmission anywhere that large groups of individuals congregate.

One of the issues with COVID-19, is when physicians perform an aersol-generating medical procedure any asymptomatic COVID-19 positive patient may release SARS-CoV-2 laden aersols into the air. Guidance from the Centers for Disease Control indicates that we can rely on our HVAC systems to slowly decontaminate the air during an hour timeframe. Studies in the medical literature are showing us that we can use portable air purifiers to do a better and faster job of decominating these airborne particles to keep our patients and staff safe.”

Air purifiers with HEPA filters can be used as very effective means to decontaminate the air above and beyond what many HVAC systems may offer,” says Sedaghat who also published studies documenting COVID-19 infection leading to reduced taste and smell in patients and possibly attacking the central nervous system.

“If people are walking around coughing or sneezing because it is allergy season and by chance they happen to be one of these asymptomatic carriers of COVID-19, there is a
danger of transmission in individuals not vaccinated,” says Sedaghat. “People are catching the disease from asymptomatic carriers.”

“The results of this study can be applied to our daily lives outside of a physician’s office,” says Sedaghat. “If you want to host larger gatherings you should consider putting the air purifiers into your living room to help decontaminate anything that is released into the air. HEPA based air purifiers work the best. HEPA based air purifiers decontaminate these airborne particles much faster and more effectively than  non HEPA filters.”

“They aren’t terribly expensive and you can buy these at any home improvement or department store to help decontaminate air borne coronavirus,” says Sedaghat. “This may be more important for controlling the spread of COVID-19 for people who are still not vaccinated.”

Air purifiers offer added protection but UC researchers also found that better-fitting facemasks greatly improve protection against COVID-19 as well.
