Dyson joins hands with China Household Electrical Appliances Research Institute to lead the development of group standards based on the POLAR method

In October 2022, the State Administration for Market Regulation and the National Standardization Management Committee officially approved the release of the national standard GB/T 18801-2022 “Air Purifier”, which will be implemented on May 1, 2023. The standard appendix contains a new automatic mode purification performance test method. The framework of this method is similar to that of Dyson’s POLAR (Point Loading and Auto Response) test method. They all start from real home scenarios and provide a close comparison for the test and evaluation of air purification equipment. The realistic perspective of consumers’ daily usage habits also provides scientific reference and industry contributions for the appendix of the new national standard “automatic mode”.

Pay attention to the problems that others tend to ignore, keep improving and explore innovation paths

Based on in-depth user insights and research, Dyson engineers found that consumers are accustomed to placing air purification equipment in a corner of the home, rather than in the center of the room. What is overlooked by many people is that this usage habit may bring challenges to the uniform purification performance of the air purification equipment throughout the house. Based on years of in-depth research on air quality and professional experience in the field of air purification, Dyson developed the POLAR test in 2017, and based on this test in 2018, jointly developed the “jet-type automatic air purification delivery system” Wind System” technical scheme, which was subsequently upgraded to the group standard “Technical Requirements and Test Methods for Air Purifier Smart Mode” in 2019. During the revision process of GB/T18801, the national standard for air purifiers, which began in 2019, the POLAR method framework was proposed to the drafting working group. After multiple verifications and amendments, it finally formed a new appendix to GB/T18801-2022. The concept of Dyson’s POLAR method is to simulate the purification needs of users in a real home environment in a larger indoor space, to test product performance in a way that is close to real usage scenarios, and to ensure its air purification capabilities in real life scenarios.

Matt Jennings, Director of Dyson’s Environmental Care Category, said: “The concept of POLAR testing can contribute to the update of national standards, and it is also a recognition of our insistence on bringing ‘real benefits’ to consumers through technological innovation. Especially in recent years, With the continuous improvement of Chinese residents’ health awareness and the diversification of home life style, people’s demand for advanced air purification technology continues to rise. Among them, Dyson not only pays attention to the latest demands of Chinese consumers, but also actively cooperates with industry authoritative testing institutions to develop Let us work together to provide consumers with high-quality air purification equipment.”

Adhere to scientific and rigorous standards, and continue to fulfill the commitment to air quality

Compared with traditional tests, Dyson engineers strive for excellence and carry out POLAR tests in an 81 cubic meter laboratory closer to the average living space. Without installing an additional mixed-flow fan, the air purification equipment is placed in a corner, and nine sensors are used to continuously monitor the air quality data of the whole house to evaluate the filtering performance, sensing performance and uniform purification effect of the whole house. This test can comprehensively and effectively guarantee the cleanliness and health of the air quality of the whole house in a real home environment.

Zhang Xiao, deputy director of the Testing Institute of China Household Electrical Appliances Research Institute, said: “I am very pleased to witness the achievements of the Dyson POLAR method from the beginning of its establishment to the present, especially the test experience and data over the years can be used in the process of updating national standards. Provide reference for relevant institutions and industries. 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 .”

Focus on real home needs and create a pure breath with “no dead ends”

Under the strict multi-dimensional evaluation of air purification equipment based on the POLAR group standard test, the Dyson air purification fan can ensure uniform purification of the whole house. The Dyson air purifying fan range is equipped with multiple sensors for precise indoor air quality monitoring. Dyson Air Amplifier airflow multiplication technology can evenly distribute purified air to all parts of the home. The POLAR test shows that the Dyson air purification fan can monitor pollutants 4.6m away in real time. After intelligent purification in automatic mode, the monitoring point with the highest pollutant content in the room is only 0.00000504g/m3.

In addition, effectively addressing air pollutants such as fine particles is still the key to helping consumers create healthy indoor air. Dyson’s new generation of air purification fans are equipped with H13 grade HEPA filters, which filter and capture 99.95% of ultrafine particles as small as 0.1 microns. At the same time, Dyson’s new generation of air purification fans can filter up to 99.9% of H1N1 virus, human coronavirus 229E and OC43 aerosols. The built-in activated carbon filter traps odors and harmful gases like VOCs. The HEPA seal design of the whole machine ensures that pollutants are firmly locked in the fuselage while sending out clean air – Dyson engineers use high-pressure seals at 24 key points to prevent dirty air from leaking through the gaps between the filters or bypassing the filters The net sprays the pollutants back into the room.

Among the many air pollutants that are invisible to the naked eye, the ubiquitous formaldehyde problem in the home is often a “big worry” for people. In addition to the long release cycle of formaldehyde, efficient and sustainable solutions have become the top priority. Therefore, Dyson has equipped the air purification fan series with a solid-state formaldehyde sensor. With Dyson’s unique algorithm, it can accurately and continuously monitor the formaldehyde level for up to 7 years. The anti-interference rate against alcohol is as high as 99.9%, and the influence of other gases can be excluded— -Other gases are monitored by dedicated VOC sensors. At the same time, the Dyson air purification fan is equipped with a catalyst filter that can continuously remove formaldehyde molecules. The filter uses a unique coating with billions of atom-sized pores inside, which can efficiently capture formaldehyde molecules and decompose them into trace amounts of water and carbon dioxide. Then, the filter is supplemented with oxygen from the air to keep the catalyst active, so as to achieve the effect of continuous removal of formaldehyde, and there is no need to replace the filter.

As an expert in the field of air quality research and purification, Dyson is not satisfied with traditional laboratory tests, and further conducts POLAR tests in an environment closer to real home use scenarios, putting forward higher requirements for its own technology and products. In the future, Dyson will continue to explore more possibilities of POLAR testing, and use innovative technology to meet the ever-increasing health needs and expectations of Chinese families.
