People are skeptical about air purifiers. Why should we buy air purifiers? Is the air purifier really useful? The answer is yes, why do you say that, let OLANSI answer it for you

OLANSI new arrival

Insert a report below: The news that an employee of Ali rented a newly renovated rental house and died of acute leukemia has once again made people fear formaldehyde and leukemia.

Everyone knows the harm of formaldehyde, but didn’t  expect it to be so serious.

  1. Carcinogenicity: In 2004, the authoritative International Agency for Research on Cancer (IARC) classified formaldehyde as a category 1 carcinogen, alongside cigarettes and alcohol.
  2. Acute toxicity: Ordinary people may die if they inhale about 7 grams of formaldehyde at a time.

What kind of existence is formaldehyde?

It is one of the common organic matter in nature and a common small molecule in the metabolism of animals and plants. Natural formaldehyde also exists in nature, but its concentration is very low. It is colorless, soluble, and irritating.

The current research cannot prove that there is a direct relationship between excessive formaldehyde caused by decoration and leukemia, but the pollution caused by decoration is real and is endangering our health.

Formaldehyde generally comes from our newly renovated new houses, and it is colorless and odorless. Even if you live for a long time, there will still be formaldehyde. If you smell a pungent odor, it means that formaldehyde is seriously exceeding the standard. Our common way to deal with formaldehyde is to open windows for ventilation and plant green plants, but the best way is actually to use an air purifier. Various air pollutants are intercepted layer by layer by the filter, and finally fresh air is filtered out.

An air purifier suitable for your family is very important to us. For the health of your children, it is not too late to buy an air purifier. OLANSI is committed to technology to create a better life for consumers. , High-quality and healthy life, to produce the most suitable air purifier for everyone. If you need a suitable air purifier, OLANSI is at your service at any time.

The choice of a good air purifier-OLANSI HEPA air purifier

Rough calculations, we have to breathe more than 800 million times from birth to death. Unfortunately, at least from the current actual situation, it is not easy to ensure this “800 million times of health”. Regarding the threat that haze poses to our health, it is true that only one or two can be gleaned from various textbooks or studies at present, and the adverse reactions mapped to our bodies are still in the “pregnancy” stage. Who knows if respiratory diseases will explode in a few years? So now, we should take the best protection. Air purifiers have been on fire in recent years. There are many air purifiers we know. How to choose a good air purifier? Olansi recommends the following items for you

 It is precisely because of health that air purifiers are different from ordinary home appliances: behind it is the health of everyone every time they breathe.

How should we protect the respiratory health of pets by using air purifiers?

OLANSI Healthcare Co., Ltd. (OLANSI for short) was founded in 2009 and is a new high-tech enterprise focusing on the research and development, production, sales and service of healthy home appliances. Committed to using technology to create a healthy, beautiful and high-quality life for consumers. Won the title of Guangdong High-tech Enterprise, 2017 China Environmental Electrical Appliances (Air Clean) Top 10 Professional Brands and many other awards.

Living in the 21st century with high work pressure and fast pace of life, pets have become treasures that soothe the souls of contemporary people. However, the sharing of living spaces with pets will inevitably face many difficulties. The relatively closed and small modern residences are not as vast as nature and the respiratory tract is healthy. There will also be problems due to odors. Next, let OLANSI talk about it in detail for you.

From a professional point of view, cough, asthma, bronchitis, herpes virus, etc. can threaten the health of pets. Severe respiratory diseases are likely to spread to the lungs, and if they are not treated in time, they may develop into long-term inflammation. Old pets with weak resistance or obesity are more likely to suffer from respiratory health problems, so it is important to purify the air and prevent them from inhaling too much impurities. In addition, cats and dogs are naturally hairy and their skin is much thinner than humans. Therefore, they cannot take frequent baths. In addition, the human habitation is not as wide as the wild, and the enclosed and small living environment will make pets have a particularly serious odor problem.

Long-term living in an environment full of peculiar smells is not conducive to health for animals or for humans who raise animals. Like humans, cats and dogs need to brush their teeth every day and take a bath regularly. They also like fresh air. For many animals, they are allergic to many impurities in the air in their daily lives. Then OLANSI will recommend several air purifiers that are friendly to pets and people!

Cleaner air is not only the key to improving the quality of life for people and pets, but also a good medicine to eliminate contradictions between people and pets. Therefore, if there are still families who are troubled by pets, let OLANSI air purifiers remove the obstacles for the family!

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.

Regarding the air purifier and air cleaner, this article explains it thoroughly

Since the rapid development of industry and construction, the air quality has become worse and worse, and the smog has become more and more serious. Many families have begun to use air purifiers. When it comes to air purifiers, many people know that it can purify the air and filter the harmful substances in the air. As for its working principle and usage skills, few people pay attention to it.

In fact, if you know more about air purifiers, you will not only be able to buy a purifier that is more suitable for you, but you can also maintain it yourself and use it for longer. Now, I will take you to learn some knowledge about air purifiers, and by the way share some air purifier products that were shortlisted for the Star Award initiated by Baidu and Zhongguancun Online.untitled.513_副本

1. Purification principle of air purifier

The air purifier is mainly composed of a motor, a fan, and an air filter. The motor and the fan promote the flow of air, so that the air passes through the air filter to absorb various pollutants, and clean air can be circulated indoors. There are also some models of air purifiers that load a negative ion generator at the air outlet to ionize the air out of negative ions, which are blown by a fan to form a negative ion current, thereby producing the effect of purifying the air.
And this filter is also different, generally made of stainless steel; there is also a composite filter, which filters out peculiar smells in the air, such as formaldehyde, etc., just like the 325 smart air purifier Y100C, which is aimed at formaldehyde and smog. A purifier is very suitable for new houses or areas with severe autumn and winter haze; the photocatalyst filter is mainly for the purification of bacteria and viruses; the nanofiber carbon filter is mostly used in places with many people such as enterprises. . Applicable people of the air purifier

Air purifiers are beneficial and harmless to everyone, and they are indispensable to individual groups. For example, children, pregnant women, the elderly, office workers, patients with respiratory diseases, and drivers. If you have a baby or a mother-to-be, an air purifier is indispensable in the autumn and winter season. When the child develops, all functions are not perfect. If you inhale too much smog or a virus, it is easy to get sick. The mother is also, not only harms the mother’s body, It will also threaten the baby’s health and cause irreversible damage. Those who have babies and pregnant women at home can choose a purifier like Philips AC3858/00, which specializes in removing haze, viruses, bacteria, formaldehyde and allergens.

The immune system of the elderly declines, and the metabolism becomes slower in the autumn and winter seasons, and it is easy to get sick. It is even more uncomfortable to inhale unclean things. The air circulation in the office is not good. If a person catches a cold, it may quickly spread to everyone. And the people who work in the office are usually very busy, don’t have time to exercise, and are easy to get sick. Haier KJ500F-EMA is a specially designed for offices. The purifier of the negative ion removes formaldehyde, secondhand smoke, etc., and the effect is very good. Not to mention patients with respiratory diseases and drivers, the outside air is not good, and they are the most affected, so air purifiers are indispensable.

3. The placement skills of the air purifier

If the air purifier is placed in the wrong position, it can really be done with half the effort. Do not place it close to walls or furniture. A distance of more than 1 meter from the wall is better. If it doesn’t get in the way, it’s best to put it in the middle of the house and try not to get too close to people.
4. Tips for using air purifier

In autumn and winter, in a dry environment, the air purifier and humidifier can be used together, and the effect will be better. Since the purifier has a limited service life and needs to be replaced every other time, it is best to choose a purifying filter with a regenerative function. In addition, most of the filters cannot be washed with water, and the purification effect will be lower after washing. Therefore, after detecting a significant drop in the purification effect, the filter should be replaced.

Air pollution is threatening human health, causing various respiratory diseases, asthma, cardiovascular diseases and other diseases. In particular, indoor formaldehyde is a serious problem. Formaldehyde is a first-degree carcinogen that can cause fetal malformations and childhood leukemia. So now everyone is paying more and more attention to environmental protection, but the air quality, especially in summer, high temperature environment, makes it easier for all kinds of substances hidden in homes, walls, books, and clothing to radiate outward.

In the past two years, with the outbreak of the new crown epidemic, consumption upgrades, consumers’ awareness of respiratory health, and air purification products have also ushered in an unprecedented outbreak. Undoubtedly, air purifiers have reaped the biggest dividend from the air quality crisis. Next, let OLANSI explain to you the importance of air purifiers.

 

In fact, for high-quality families, air purifiers have become the standard for home air purification. After all, who doesn’t want to have fresh air in their homes every day, and that their families can enjoy fresh air every day? Indoor pollutants are mainly divided into several types: formaldehyde, PM2.5, benzene series and TVOC.

 

Friends who know about indoor pollution must also know that formaldehyde is the most difficult to deal with among these pollutants, which is different from other pollutants. , The volatilization period of formaldehyde can be as long as 3-15, and it has the stubbornness to repeatedly exceed the standard. Secondly, relatively speaking, formaldehyde is the most harmful. Formaldehyde can not only cause various respiratory diseases, but also cause infertility, fetal malformations, and even induce childhood leukemia, carcinogenesis and death. The role of air purifiers can be said to be very important for scenarios such as serious air pollution, sensitive people at home, and mothers and babies. Then OLANSI recommends several products to protect our healthy breathing, so that everyone is no longer troubled by air pollution:

It is no secret that smoke inhalation is harmful to the lungs. But now, scientists believe that smoke may also carry and spread infectious diseases.

 

A study found that the smoke from wildfires is filled with thousands of microorganisms, some of which are known to cause diseases, such as bacteria and fungal spores. A recent report in the journal Science pointed out that “smoke may carry and spread infectious diseases.”

 

Scientists said that because these bacteria or fungi will be adsorbed on smoke particles and travel thousands of miles and across continents, they have the possibility of spreading infectious diseases.

 

Although whether smoke-borne microorganisms may cause human infections remains to be confirmed, some scientists believe that this possibility is considerable. Because in some areas, the increase in the incidence of fungal-related diseases is positively correlated with the increase in wildfire smoke. The US Centers for Disease Control and Prevention also reminded that firefighters are at a higher risk of getting Valley Fever. Valley Fever is scientifically called Coccidioidomycosis, which refers to people who have fever and rashes due to inhalation of spores in the soil. And other symptoms.

Bacteria are so terrifying, then OLANSI recommends several products to protect our healthy breathing, so that everyone is no longer troubled by air pollution:

Because our living environment is now polluted, there are a lot of bacteria and dust in the air. If inhaled into our respiratory tract, it will cause respiratory tract infections and cause tracheal diseases, so purifiers came into being. For the applicable people and applicable occasions of the purifier, we must pay more attention to understanding, and then let OLANSI explain it for you.

 

  • The most important thing is pregnant women. Pregnant women will feel general malaise when indoors with serious air pollution, such as dizziness, sweating, dry tongue, chest tightness, vomiting and other symptoms, which have an adverse effect on the development of the fetus. A set of scientific data shows that pregnant women who have been exposed to air pollution for a long time are three times more likely to develop heart disease in their fetuses than those born to babies born to pregnant women who breathe fresh air.

 

  • The second thing is about children. Children’s bodies are developing and their immune systems are relatively fragile. They are vulnerable to indoor air pollution, resulting in decreased immunity, delayed physical development, induced blood diseases, increased the incidence of childhood asthma, and made children The intelligence is greatly reduced.

 

  • Again, it is the middle-aged and elderly people, who have decreased physical function and often suffer from a variety of chronic diseases. Air pollution not only causes respiratory diseases such as bronchitis, pharyngitis, and pneumonia in the elderly. It can also induce high blood pressure, heart disease, cerebral hemorrhage and other cardiovascular diseases.

 

  • In addition, we want to talk about the driver, the driver has been driving for a long time, the car is lack of oxygen, and the car exhaust pollution is serious. At this time, it is necessary to equip the car with an air purifier, which can absorb the poisonous gas on the car and reduce the exhaust pollution.

Air pollution is so harmful to the human body. The next few products that OLANSI recommends to everyone are product designs for most people, and the main product design is a combination of multiple filtration technologies:
