Winter approaches, outdoor temperature drops sharply, "staying at home" has become the usual way for many people to spend the winter. Close the doors and windows, turn on the air conditioning and heating, and keeping a cup of hot tea seems to be the standard winter for most people; of course, many people have experienced a summer decoration and a vacant new house, and are preparing to move into a warm new house in winter. A few friends can enjoy hot pot at home together, and immerse themselves in the hot atmosphere of the house with their family, friends and even "haired children". This is a kind of happiness that only comes with winter.
However, the air pollutants released by the "routine operations" such as adding new furniture, cooking and stir-frying, as well as the odors and allergens that may be brought about by fashionable lifestyles such as homemade hot pot and pet raising, are all locked in the house with tightly closed doors and windows. While enjoying the joy of home in winter, people may also spend more time with indoor pollutants.
Modern people are paying more and more attention to their own breathing health, which has also given rise to their strong demand for air purification equipment. However, how to choose products suitable for your home environment has caused many consumers to have a headache, such as whether they can cope with the long-term release of formaldehyde , or whether they can use a machine to ensure the "blind corners" of the home.
For ordinary consumers, the new "concept" of products on the market is overwhelming, technical concepts are difficult to understand, functions are too numerous to choose, and the filtering effect of billions of dollars is even more difficult to distinguish. People often find it difficult to distinguish high-quality products that bring "real benefits" to their homes. Fortunately, the release of the new national standard of "Air Purifier" further standardizes the technical standards of purification equipment and puts forward higher requirements to ensure that consumers purchase high-quality products that are close to the needs of their home environment.
New national standard for air purification has been released, becoming the group standard for consumers that "understand" the most 'comprehensible' to consumers
In October this year, the State Administration for Market Regulation and the National Standardization Management Committee officially approved the issuance of the GB/T 18801-2022 "Air Purifier" national standard, and is scheduled to be implemented on May 1 next year. It includes 9 chapters and 15 appendices, involving 7 types of technical requirements and 14 testing methods. The new national standard was revised based on the 2015 edition. The appendix supplemented and improved relevant testing methods, further standardized the technical parameters of the air purification industry, and put forward stricter requirements for air purification equipment, thus providing guarantees for consumers to obtain reliable, efficient products that meet real home needs.
new national standard, on the one hand, looks at the core considerations of consumers when purchasing air purification products, standardizes and simplifies the labeling form, and further optimizes the correlation of various parameters; more importantly, the revised new national standard focuses on the current air pollution situation in the home environment, not only optimizes the test methods for removing gaseous pollutants, but also improves the standards for allergen and virus removal performance in the appendix, and even the test and evaluation of uniform purification performance of the whole house, providing consumers with comprehensive and scientific measurement standards.
"realistic" test keeps improving, and industry-research cooperation promotes high-quality development in the industry. It is worth mentioning that it is precisely because of the real home environment and purification experience of consumers. The appendix of the new national standard contains a new automatic mode purification performance test method. The framework of this method is similar to the Dyson POLAR (Point Loading and Auto Response) test method. Both start from real home scenarios and provide a realistic perspective close to consumers' daily use habits for the test and evaluation of air purification equipment.
Dyson Engineers found that consumers are often used to placing air purification equipment in a corner of their home rather than in the center of the room. What many people ignore is that this usage habit may bring challenges to the uniform purification performance of air purification equipment throughout the house.
is the insight into the hidden consumer pain points behind it. Based on long-term air quality research and professional accumulation in the field of air purification, Dyson developed the POLAR test in 2017, which was carried out in a laboratory closer to the average living space.
Without installing an additional mixed flow fan, the air purification equipment is placed in a corner. At the same time, 9 sensors are used to continuously monitor the air quality data of the whole house to evaluate the filtration performance, sensing performance and uniform purification effect of the air purification equipment. It can be said that the POLAR test simulates consumers' daily home environment, usage habits and real purification needs, and further ensures the air purification ability of air purification equipment in real life scenarios.
Based on the concept of POLAR testing, Dyson joined hands with China National Electrical Appliances Research Institute (CHEARI) in 2019 to gradually upgrade the technical solution to the group standard of "Technical Requirements and Test Methods for Intelligent Mode of Air Purifiers" and proposed to the drafting working group of the national standard. After multiple verifications and corrections and improvements, the new appendix for GB/T18801-2022 was finally formed. Zhang Xiao, deputy director of the Testing Institute of the China National Electrical Appliances Research Institute, said: "I am very happy to witness the achievements of the Dyson POLAR method from its inception to the present, especially the years of testing experience and data that can provide reference for relevant institutions and industries in the process of updating national standards. With the continuous development of my country's air purification industry, we believe that in the future we will see more scientific innovations based on real consumer insights, and look forward to working together to promote the high-quality development of China's air purification field."
multiple core technologies lead the development, science first implements the promise of air quality
mentions the real scenarios of consumer use, and the release of the new national standard also seems more timely. Based on the demand for even purification of the whole house, staying at home in winter is not only the potential air pollutant itself, but may affect people's breathing health. Heating and air conditioning will also take away moisture from the air, and dry and dull spaces can easily cause problems such as physical discomfort.
Therefore, it is more important to create a comfortable, moist and clean home space in the whole house in winter. Faced with the discomfort caused by indoor air drying in winter, Dyson's new generation humidified air purification fan PH04 is equipped with fog-free humidification and sterilization technology [1] on the basis of efficient purification of the whole house, to achieve a safe and clean humidification experience.
Dyson air purification fan series are equipped with multiple sensors to achieve accurate indoor air quality monitoring. POLAR tests show that with the support of Air Amplifier airflow doubling technology, Dyson air purification fan can monitor pollutants outside 4.6m in real time, and evenly spread the purified air to all parts of the home [2].
In addition, effectively solving air pollutants such as fine particulate matter is still the key to helping consumers create healthy indoor air. Dyson's new generation of air purification fans are equipped with H13-level HEPA filter [3], which filters and captures 99.95% of ultra-fine particles as small as 0.1 microns [3]. The HEPA seal of the whole machine [3] ensures that the pollutants are locked firmly on the body while sending out clean air, preventing dirty air pollutants from spraying back into the room.
For the number one problem among air pollutants - formaldehyde released with diverse sources and long-term release, Dyson air purification fans can be "in one step" to achieve long-term removal. This is due to the solid formaldehyde sensor equipped by Dyson for the air purification fan series. It is equipped with Dyson's unique algorithm to accurately and continuously monitor formaldehyde levels for up to 7 years [4].
At the same time, Dyson air purification fan is equipped with a catalyst filter [5] to continuously remove formaldehyde molecules [6], efficiently capture formaldehyde molecules and decompose them into trace amounts of water and carbon dioxide , and replenish oxygen from the air to maintain catalyst activity, thus achieving the effect of continuously removing formaldehyde without replacement.
As a persistent innovator and researcher in the field of air quality, Dyson has always been striving for excellence and is constantly committed to paying attention to real problems that people are prone to overlook in the home environment and solving them. In the future, Dyson will continue to explore more possibilities for POLAR testing and use innovative technologies to meet the ever-increasing health needs and expectations of Chinese families.
