From July 15th to July 16th, 2019, the National Household Appliances Standardization Technical Committee Cleaning Appliance Subcommittee held the first meeting in Guangzhou, on the revision of GB/T 18801-2015 “Air Purifier” national standard. The standard revision plan number is 20190972-T-607, the release date is March 28, 2019, and the work cycle is expected to be 24 months. More than 50 technical experts from mainstream enterprises in the air net industry participated in the meeting.
Ma Dejun, vice president of China Household Electrical Appliances Research Institute, delivered an important speech on the current background of air purifier industry, global environmental pollution, and the development of IEC standards for air purifiers. He said that current air purifiers are not limited to removing particulate matter and future product development. It is necessary to combine pollen allergens, ozone, odor, and other issues; not limited to the domestic market, India and other developing international markets are also in great demand. He said that the development of products should keep pace with the times, and the standards should fully consider the status quo of the industry and consumers. I hope that the revision of standards can fully consider the market and social needs under the new situation.
Participants and experts fully expressed their opinions on the revision of the standard and discussed the draft standard. The meeting reached a basic consensus on the standard revision content and the overall framework. The standard revision direction is as follows: the gaseous pollutant test method is changed to the continuous dynamic balance method; the CCM is no longer graded separately, and the file is directly divided according to the CADR; the technical requirements of the silent mode are added; the test cabins of 10m3 and 81m3 are added; and the performance evaluation method of the automatic mode is added; Increase the filter odor evaluation method, etc. At the same time, as China is taking the lead in formulating the international standard IEC 63086 for air purifiers, the revision of GB/T 18801 also refers to the relevant technical directions of international standards.
The National Household Appliance Standardization Technical Committee has arranged the follow-up related work, requiring all units to combine the industry and consumer status, strengthen the research in the technical field on the basis of the standard overall framework, and further improve the core content of the standard.

In 2018, China’s air purifier industry entered a stage of rational development, and all parties involved in the industry continued to explore the future development direction of the industry during the year. The overall improvement of the overall air quality in the country does not change, but we should also understand that the quality of the air environment at this stage is far from the overall excellent level. In the first quarter of 2019, the central and eastern parts of the country experienced a period of moderate smog invading. The government has spared no effort in governance to get the current quality of the air environment. In the important stage of China’s economic restructuring, the development of the break is a topic that every empty net person should think about.
The air purifier market continued to decline in the first quarter of 2019. From the perspective of product structure, the e-commerce platform of large particle CADR value products has dropped by more than 30% year-on-year. Especially in the e-commerce platform, the particulate matter CADR 800+ category has not been able to effectively drive the market. The offline market is slightly better than the e-commerce platform. But still in a negative growth state. In the current empty net market, in addition to aldehyde products is the focus of the layout of various manufacturers. From the perspective of the market in the first quarter, the e-commerce platform’s strong performance in addition to the aldehyde empty net model is not satisfactory, and the offline market has a strong performance in addition to the aldehyde market and has become the main market turnover category.
Although the overall net market is in a downturn, the e-commerce platform is selling 313 brands in the first quarter of 2019, a decrease of about 100 compared with the same period of last year; the number of offline sales brands is also decreasing. However, brand competition is still the same. The top ten brands of e-commerce platforms are concentrated at around 70%, which is basically the same as last year. The top ten brands in the offline market are close to 90%, which is slightly lower than last year. In the post-smog era, the empty net market needs to empower itself, out of the “PM2.5” product dilemma, and capture market opportunities in the market segments.

Olansi is a professional manufacturer of air purifiers, producing anion air purifiers, activated carbon air purifiers, HEPA air purifiers, antimicrobial air purifiers, etc.
It is well known that formaldehyde is very harmful to the human body, but it is usually caused by olfactory disturbance, irritation (irritation, tears), pulmonary dysfunction, excessive formaldehyde inhalation caused by prolonged exposure, and various chronic respiratory diseases. Nasopharyngeal, colon and infant chromosomal abnormalities can also lead to memory and mental deterioration in adolescents and leukemia.
As far as formaldehyde is concerned, many people think it has something to do with the decoration and building materials for new houses. Because of this, such as “carcinogenicity of formaldehyde”, the relationship between formaldehyde and decoration is unilaterally misunderstood and understood.
Hepa filter
In terms of decoration and formaldehyde, everyone’s reaction is usually synthetic wood and building materials. When we see “zero formaldehyde” in the choice of decoration, it is easy. You can use “zero formaldehyde” boards and furniture to inhibit formaldehyde at least to some extent, but this is harmful.
In fact, formaldehyde is not something to be used for decoration, it is only hidden in the paint and adhesives used in the construction process. Although it is used for decoration, a urea-formaldehyde resin containing formaldehyde is the necessary adhesive for decoration.
In other words, as long as adhesives are used, even if all purchased materials are “zero formaldehyde”, they are also exposed to the “main body” of formaldehyde. The amount of formaldehyde remaining in the process of making urea-formaldehyde resin is called free formaldehyde. This part of free formaldehyde is released when the coating flattens and solidifies, which is the direct harm of formaldehyde decoration.
There are too many places to use adhesives in decoration, such as putty, paint, adhesives, wallpaper, hardened wood flooring, particleboard, MDF, and even solid wood. I don’t need formaldehyde in the process of home decoration.
All we can do is to minimize the formaldehyde content of each product because it is inevitable! For example, try not to use wood flooring, composite materials or as few layers as possible! The formaldehyde content is as low as possible… as long as the formaldehyde content is within a certain range, it will not be so bad!
As mentioned above, formaldehyde is acceptable in a certain range of indicators, but it promotes the volatilization of formaldehyde, i.e. high temperature when it occurs in our daily life.
According to the investigation, the volatilization point of formaldehyde is 19 C, and the temperature rises by 0.4 liters every time, especially in spring and summer, the temperature rises faster and the concentration is more than three times as high as usual.
Originally, in winter, the temperature dropped and the formaldehyde emission decreased, but due to the need to heat the house, such as the north’s ground temperature and the south’s air conditioning, the formaldehyde in the room was hidden by paint, floors, and furniture. There will be a lot of releases.
In fact, formaldehyde can not be completely eliminated. The methods of removing formaldehyde on the network can be divided into several types. The public and the public husband say that women are reasonable, and then let’s see what their truth is…Contact us for more products and discounted prices

The suffocating smog from Monday to Beijing and many of the country’s more serious conditions have triggered such a smart crack by social media users in catastrophic circumstances.
In the past few days, jokes on this topic have become one of the most discussed topics on Sina Weibo, China’s largest microblogging website.
However, despite a casual attitude towards the harmful atmosphere, residents of the capital have felt the impact of one of the smokiest games in Beijing since July.
The National Meteorological Center (NMC) upgraded its yellow warning on Tuesday afternoon to the second tallest orange on Thursday afternoon.
She came home with urticaria for five months, but blood tests showed that she was allergic to substances in the air.
“When I traveled outside Beijing, my symptoms were relieved,” she said, but the rash had worsened in the past two days.
At Guang’anmen Hospital, a doctor told her that her symptoms were affected by smoke.
An unknown staff member of Beijing Children’s Hospital told Xinhua that they had not seen a significant increase in the number of patients preparing for the peak respiratory problems because the smoke had just begun.
“Every time smoke continues, more students ask to be ill,” said Professor Wang Xia, 34. ”
Beijing’s environmental monitoring agency suspects that farmers have accused burning straw fields of causing smog, and Beijing suspects that.
However, Li Lixin, an air pollution control officer of the Beijing Environmental Protection Bureau, conducted satellite tests in the summer of 2013, and amplified fire discharges were used to measure PM 2.5 readings of 110 to 460 microns in Beijing. A few hours later, it showed that it could pull up to gram/cubic meter.
However, Internet users question prices.
“Agriculture has become an important industry in China for hundreds of years, even hundreds of thousands of years. After harvesting in autumn, farmland harvests straw and ashes as fertilizers. “It’s a tradition,” said Weibo users, nicknamed Sunflower, “but why didn’t smoke in the past?”
In response to such criticism, Wang Yu, who is in charge of Beijing’s energy ecosystem, said that pollutants mainly come not from burning straw, but from automobile exhaust, coal combustion, industrial production, and dust. I admit it.
“But this is the season for burning straw, which is consistent with the special climate of high humidity and windless. It’s like straw breaking a camel’s back and causing air pollution, “he said. I have told you.
It is not the only smoke control measure to ban firewood cutting in Beijing and its surrounding areas.
In addition to banning straw, the city has promised to replace coal with cleaner-burning energy, such as household electricity and natural gas, coal sales and use by the end of 2020, and other highly polluting fuels. I want to suppress fuel oil, petroleum coke, combustible waste, biomass fuels, etc.
Beijing also levied fees on major pollutants such as sulfur dioxide and nitrogen oxides this year.
Li Lixin said it may take some time to see the results of such a measure, but the government believes that the issue is very important and people’s awareness of environmental protection has improved.
Meanwhile, Beijingers shunned outdoor activities and excluded thousands of people from indoor protection.
An anonymous old man named Chen said that his friends with asthma and bronchitis would remind them not to go out in the smoke.
Wang Xia’s school has stopped carrying out outdoor activities for students. “What if we can install every classroom,” she said.
Sales of air purifiers have almost doubled in the past two days, according to Zhang, a sales representative for the e-commerce platform Jingdong Electronic Brand SHARP.
“I bought this for her because my granddaughter is very young,” she said. Well, I hope it will clear up soon. ”

HEPA represents highly efficient particulate air and is a type of filter used to absorb air pollutants such as pet dander, pollen, tobacco smoke, mold, dust, and dirt. It requires flushing allergens for allergic and asthmatic patients.
HEPA represents highly efficient particulate air and is a type of filter used to absorb air pollutants such as pet dander, pollen, tobacco smoke, mold, dust, and dirt. It requires flushing allergens for allergic and asthmatic patients.
Definition of HEPA filter
Also known as high-efficiency air filters, fiberglass fibers, depth filters are designed to be arranged independently, and their porous design can accommodate particles of a certain size (through the filter stage), they will not return to the environment I will. Because of the nature of the design, these filters can hold a lot of waste before they need to be replaced.
Sometimes these air purifiers combine activated carbon filters, ultraviolet rays, and sometimes use HEPA in parallel with ion generators to further clean the air.

Anti-asthma in children with the air purifier
Early detection is the first step in combating childhood asthma
Does your child have short or irregular breathing? Does he or she notice a scream when he or she exhales? Does your child continue to cough? If so, he or she may already have asthma. The most serious chronic disease among children and adolescents affects about 9 million children under the age of 18.
According to the American Academy of Allergic Asthma Immunology (AAAAI), early detection and collaboration with childhood asthma specialists are important because 50-80% of asthmatic patients develop symptoms before they are 5 years old. Airway damage may make it difficult to control the condition.
“Children with immunodeficiency have the highest risk of asthma,” said Dr. FAAAI, vice president of the AAAAI Asthma Diagnosis and Treatment Interest Department. This is. Diseases are easier to manage and improve children’s quality of life. ”
Look, listen, learn
There is no clear marker to predict who will develop asthma, and no one will, but children have clues and symptoms that may indicate asthma.
Does your child have allergies? The relationship between asthma and allergy is very strong.
Even if you are not ill, does your child often cough or cough? This may be a routine or intermittent symptom.
When your child breathes or is associated with upper respiratory tract infections, does your child wheeze or scream?
Are you aware of your child’s breathing difficulties, shortness of irregularity?
Does your child complain of chest tightness? A young child may say that his or her chest is “painful” or “interesting”.
Does your child look tired? Your child may slow down, stop playing or be stimulated.
Does your child have sleep disorders due to coughing or dyspnea at night?
Do you have a family history of asthma or allergy?
Answer “Yes” to any of these questions. If you suspect that your child has asthma, consult an asthma specialist, such as an allergist/immunologist, or a specially trained doctor to treat and treat asthma and allergies. Appoint immunologists to work closely with you to develop a daily management plan for your child, demonstrate appropriate drug use, and outline actions to be taken if your child’s condition deteriorates.
Study
There is no cure for asthma, but through proper treatment and treatment, the disease can be completely controlled. Measures to reduce asthma symptoms in children are an important step in controlling asthma in children. If managed properly, you should be able to participate in daily activities, such as going to school every day for exercise.

According to the American Academy of Allergic Asthma Immunology (AAAAI), seasonal allergic rhinitis or “pollen fever” affects more than 20% of Americans. Many trees, grasses, and weeds contain small, light pollen carried by the wind, and allergic symptoms occur again in spring.
Allergic patients find remission tips during allergic season
Make a thorough spring cleaning window, bookcase and air conditioning vent will collect winter dust and mold, which may lead to allergic symptoms.
Use a new air purifier filter. If you have been operating the air purifier, monitor the adhesion of the filter.
Bath and shampoo before bed – Pollen can be collected in your hair and skin.
Do not leave pets near furniture or outside the bedroom. Pollen will stick to dogs and cats when they go out.
Keep windows closed during peak season and use air conditioning to keep vents away from your face.
When mowing or gardening, wear a filter mask. Contact us for more products and discounted prices
