Heavy air pollution hits, and the air purifier market reappears

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

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

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

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

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

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

 

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

What exactly is the “second pollution” of air purifiers? How to prevent and solve it?

In view of the epidemic and air pollution, everyone’s awareness of air purifiers is getting higher and higher, but perhaps everyone knows little about the “secondary pollution” problem, and some people have not even heard of it. The main phenomenon of “secondary pollution” in air purifiers is: the air purifier has been used for a long time without being cleaned up in time, including replacing the filter element or doing a good job of cleaning, resulting in a decrease in the purification efficiency of the air purifier or even the original air The bacteria and viruses attached to the filter of the purifier evaporate twice, causing the original clean air to be contaminated. If people spend a lot of time in the air that has been “secondarily polluted”, they may suffer from nasal congestion and allergies, and in severe cases they may be infected with diseases. So when you use an air purifier, you must strictly prevent the phenomenon of “secondary pollution”, so how to prevent this from happening? Let me give you a brief introduction.

WJHWMJ(82U2L2C`@U8UA[[J
1. Let me talk about the formation principle of “second pollution” first

Because the performance of the air purifier is constantly improving, its filter system is more likely to allow pollutants to accumulate in the filter, and the long-term accumulation of pollutants around the filter will provide a breeding environment for microorganisms such as bacteria and viruses that are inhaled at the same time. If the air purifier does not have a better sealing performance, when the contaminants on the filter are saturated, it will easily be emitted from the air outlet, and then may be directly discharged to the person through the fan. This whole process is the so-called “secondary pollution.”

Many people say that it is not difficult to solve the “secondary pollution”, just clean or replace the filter, but you can be very responsible to tell you that even if you clean or replace the filter frequently, the “secondary pollution” cannot be completely avoided. Because the inside of the air purifier is isolated by a filter, a strong wind pressure will be formed inside, which will form a pressure, and the bacteria and viruses inhaled by the air purifier may escape from the unsealed part of the air purifier. And the gap between the filter and the fuselage is discharged into the indoor air again.

2. What is the phenomenon of being “secondarily polluted”

In fact, when the air is “secondarily polluted”, it is easy to feel. For example, when the air purifier is used for a long time, the wind blown out will have a more obvious air particle feeling, and it will also have a strange smell. This is the “secondary pollution”, which not only contains dust and bacteria, but may also contain chemical and optical pollutants, such as ozone and organic particles. If people breathe in “secondarily polluted” air for a long time, it is more likely to cause physical discomfort such as rhinitis and allergies. So we buy the dubbing of the air purifier to purify the air, but in the end it may be counterproductive because of the “secondary pollution”.

K15B

3. How to solve the “second pollution” problem?

In fact, as mentioned above, the root cause of “secondary pollution” in an air purifier is still related to the filter screen, structure and air duct of the air purifier itself, as well as the airtightness. The position of the activated carbon filter of the air purifier should also be considered. If the filter position is in front, the activated carbon will adsorb air particles and gaseous pollutants at the same time. As the adsorbed particles increase, the activated carbon will be blocked, which will reduce the filtering effect. So this reminds us that only by optimizing the product structure, increasing the airtightness of the whole machine, improving the filter level and improving the filter order can the air purifier manufacturers really improve the quality of air purification. This also tells us consumers that if you want to eliminate “secondary pollution”, you must consider the performance of air purifiers and the ability to purify pollutants, which are really crucial.

4. The industry’s exploration of “secondary pollution”

As more and more air purifier manufacturers join, the manufacturing level of the entire air purifier industry is constantly improving, which also promotes the continuous updating of air purifiers. For example, new air purification technologies such as complete machine sealing technology, catalyst oxidation filters, solid-state sensors, etc. continue to emerge, which greatly enhances the confidence of air purifier practitioners and enhances the consumer experience.

The above is the interpretation of the relevant content about the “second pollution” of the air purifier that I shared with you this time. I hope it will be helpful for everyone to understand the air purifier.

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

 

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

 

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

 

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

 

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

Do air purifiers work?

First, check the sealing,

Air purifier has a certain purification effect on air impurities, but there is no complete purification ability, because it can not circulate the whole room, but the sealing of the air purifier is one of the key elements of the effect of the air purifier. Because of the poor sealing of the purifier, a lot of polluted air can not “pass through” the filter element, but from the corner of the purifier “leak”. Only with good sealing, all polluted air can pass through the filter element and be fully filtered, the single purification efficiency of the purifier can be guaranteed. But better sealing means more wind resistance and more noise. Therefore, the practice of ordinary purifiers is that the filter element is thin, the sealing is almost bad, and the purification efficiency is low. This allows the room air to be filtered more times per hour with a larger air volume. But this “extensive” filtration mode, only suitable for the purification of the general consumer is not high;

Second,check the quality of the filter ,

At present, high-end air purifiers in the world adopt pure physical filtration technology without exception. Therefore, the quality of the filter element plays a decisive role in the purification effect. For example, the grade of HEPA filter element, theoretically speaking, the higher the grade of HEPA filter element, the higher the filtering efficiency of particulate matter. For example, in activated carbon filter element, the level of modification technology determines the adsorption efficiency of activated carbon filter element. There are alumina, zeolite and other filtration materials with low adsorption efficiency to replace or partially replace high-quality activated carbon filter, these will also have a negative impact on the efficiency of activated carbon filter adsorption formaldehyde and other chemical gaseous pollutants;

A4_2

Third, check the weight of the filter,

Generally speaking, whether it is activated carbon filter element, or HEPA filter element (including anti-microbial filter element), the thicker the filter element, the heavier the weight, the higher the adsorption and filtration efficiency. However, the thicker the filter element is, the greater the wind resistance is, the higher the requirements for the wind system are, and the manufacturing difficulty and cost of the whole purifier are also higher. So many air purifiers on the market with relatively thin HEPA filter and activated carbon filter, the new national standard, and according to the existing air purifier this thin filter with the shorter the distance from the wind (that is, pollute the air through the filter of distance), it is easy to achieve greater CADR value (both formaldehyde and particulate matter) and the value of CCM, It is easier to be accepted by consumers. However, in fact, this thin activated carbon filter element and HEPA filter element, the capacity of pollutants is low, easy to saturation, short life, especially adsorption and purification efficiency is low;

Fourth, check the matching of filter element and wind system,

A lot of people think air purifiers are low-tech. Many common purifiers on the market are basically composed of a fan and a number of filtering materials placed inside the shell. In general, it filters out a lot of pollutants. But it’s not really an efficient air purifier. What kind of structure and how thick and multiple filter elements are used by air purifiers need to be determined by strict testing and calculation. If the filter element is not well matched with the wind system, it is easy for large particles to penetrate the HEPA filter element, resulting in the loss of “efficiency” of the HEPA filter element. For example, if the same medical-grade HEPA filter element is installed on two different purifiers, the purification efficiency of the air purifier may be completely different: the professional purifier will strictly match the corresponding filter element according to the requirements of the wind system, in combination with the structure of the purifier, the wind passage distance and other factors. For example, HEPA filter element is pre-activated carbon filter element, anti-microbial filter element and primary effect filter element of filtering large particles, and these different filter elements “each plays its own role”, so as to achieve the purpose of making HEPA filter element mainly filter PM2.5 ultra-fine particles; As a result, although the HEPA filter element is of the same medical grade, due to excessive air volume and thin filter element, it is likely that in a very short time after the purifier is turned on, large particles (such as PM10, PM5, PM3 and PM2.0) will “penetrate” the HEPA filter element. Thus, the HEPA filter element “fails” for ultrafine particles such as PM0.5. And whether the ultrafine particles below PM0.5 can be efficiently filtered is one of the important evaluation criteria of whether the purifier is “effective” from the health perspective.

Air purifier manufacturer tells you the role of air purifiers

Like clean water, clean air is also necessary for human health, but many people do not realize how seriously our indoor air has been polluted. No one wants to drink polluted water, but why do we want to breathe unclean air? In fact, indoor air pollution is more serious than outdoors. Because the items commonly used in our lives, including carpets, furniture, dry-cleaned clothes, electronic equipment, portraits, solvents, electric stoves, etc., will pollute the indoor air.

1

Many items in rooms and offices also pollute the indoor air, and if some of the home decoration materials in the home will continue to produce formaldehyde, it will be inhaled into the body for a long time, just like drinking a chronic poison! !

At present, there are a wide variety of air purifiers on the market, but there are very few that can really purify indoor air. They can only remove dust in the air, but cannot completely remove harmful substances in the air. Although dust pollution is also a big problem, the real freshening of indoor air cannot be done by removing dust. Severe air pollution can lead to more serious hazards such as cancer and heart disease, so if most air purifiers just remove dust, they are not real air purifiers.

K15B

Olansi is a manufacturer specializing in the production of air purifiers. It has more than ten years of production experience and unique design. The ultimate goal of the air purifiers produced is to remove all harmful substances in the air, including air chemicals, bacteria, peculiar smells, Dust, dust, formaldehyde, etc.; the polluted air is sucked into the air purifier and emits negative ions to purify it, so we can naturally breathe indoor air with confidence.

The purifying effect of the air purifier is beyond your imagination. Compared with other ordinary air purifiers, it has no complicated machinery and application procedures. It can be used with one button only with Swiss pure essence oil, and the whole machine It is compact and can be moved at any time.

Olansi air purifiers can be purified by machines to get healthy and clean air.

 

How to use water purifier and where to buy

As the saying goes: People take food as the sky, food as the water, and water as the net. Because water is important, we are increasingly demanding the quality of drinking water. Today, as water purifiers become more and more common, some friends still ask: Is it necessary to install a water purifier?

 

In fact, the tap water seems to be clean, but it is through the chlorine treatment of the water plant, the municipal pipeline transportation, and even the secondary water supply system of the community water tank, etc., only to come to the faucet of every household, the impurities inside may be more than imagined. We can use the following simple methods to identify the water quality in the home.

 

1, look

 

Fill the water with a glass with a high transparency, and see if there are suspended impurities and precipitated impurities in the water against the light. If there are impurities in the water, it means that the water quality is too bad to meet the drinking standard.

 

Look at the kettle, look at the commonly used kettle in the house, is there a layer of yellow scale on the inner wall? If it is stated that the hardness of the water is too high (and may contain rust).

 

See if there is any sediment after the water is stopped.

 

2, smell

 

After picking up the water with a glass, smell it. If you can smell the bleaching powder (chlorine), it means that the residual chlorine content in the tap water is more.

 

3, taste

 

Tasting the boiled water, the taste of the mouth is awkward, indicating that the water has a higher hardness.

 

4, the water has a sticky feeling and is greasy

 

If the water body is found to have a certain viscosity, the specific performance is that the faucet is closed when there is a hanging wire, the chopsticks can be drawn, and the hand feels slippery when washing hands, indicating that the water body may be contaminated by microorganisms.

The quality of water can be distinguished by the above five methods. What if there is pollution? Can the water purifier be solved? I believe that many people have a little knowledge of the water purifier.

A water purifier is a device that converts “not clean water” into “relatively clean water”, and the classification can be divided by its filtration level. More commonly used in the market are ultrafiltration water purifiers and reverse osmosis water purifiers, in addition to soft water machines.

 

The function of the water purifier is to filter out the rust, sand and gravel in the water, as well as the residual chlorine, smell, color, pesticides and other chemicals in the water.

 

It can remove impurities such as bacteria, germs, microorganisms and heavy metals in the water.

 

The water purifier can directly clean the tap water, remove residual chlorine in the water, and change the quality of drinking water in the home.

 

If you want to install a water purifier, look at the filter element below:

 

The filter element of the water purifier is like the “kidney” of the human body. The water quality of the water purifier is not only dependent on the quality of the filter element, but also depends on whether the life of the filter element is replaced in time. If the filter element is not replaced for a long time, it will cause water blockage, not only the water will become smaller, but also the filtering effect will follow. The weakening, in this way, the water passing through the water purifier will not be well purified, and the degree of purification will naturally decrease.

 

To know that the human body contains 70% of water, when the water we drink is too high, the kidneys bear a very heavy filtering burden. Once some impurities cannot be filtered out, they will slowly accumulate in our body for many years. It is likely to form a disease.

How to properly maintain the OLANSI air purifier

As people pay more attention to air pollution and demand for quality of life. Household air purifiers are bound to be recognized and accepted by more and more people! So how to maintain household air purifiers in life? This question will also be paid attention to by more and more people. Today, I am personally concerned about household air purification. Let me share with you the experience of how to maintain the device:

K15B_22

First, external maintenance of the chassis

 

  1. Clean the dust and dirt on the outside of the case regularly. It can be wiped with a dry soft towel or a damp cloth, remember to use engine oil, banana water, etc. for scrubbing.

 

  1. Regularly check whether the power line is damaged. The air purifier is an electrical product, so ensuring that the power line is intact is a job that cannot be ignored, first to ensure the safety of electricity, and second, to ensure that the air purifier can run well!

12

Second, the internal maintenance of the chassis

 

  1. Maintenance of the front filter (usually the back cover of the case). The pre-filter should be cleaned 1-2 times a month. Remove the filter, tap it or blow it clean with a hair dryer. You can even wash it with water, spin dry, and then install it into the panel!

 

 

2, formaldehyde filter maintenance. The maintenance of the formaldehyde filter is special. It does not need to be cleaned. The best maintenance method is to regularly expose it to the sun to keep the filtering function of the formaldehyde filter in the best condition.

 

  1. Active carbon filter maintenance. The activated carbon filter needs to be replaced regularly and is a disposable consumer product. If you can also get it under the sun regularly, you can appropriately extend its follow-up time.

 

  1. Dust removal inside the case. The air purifier has been working for a long time, and some dust will inevitably be invaded in the case. The cleaning can be done with tools such as vacuum cleaners and hair dryers. Be sure to cut off the power before cleaning the inside of the machine!
