The increasing market demand has led to the influx of a large number of manufacturers, and the air purification track is quite crowded. In order to attract consumers, various brands have launched products with diverse functions and different types, but the professional indicators of their publicity are difficult to distinguish for ordinary consumers. For consumers, before buying, they need to know their own needs and the characteristics of the home environment, and then choose the equipment with appropriate functions; At the same time, it is also necessary to judge whether the product can really meet the daily use needs according to the personal usage habits, and even the region and climate have become important considerations.
Seasons increase winter lifestyle or "mine" indoor air.
With the arrival of the cold wave and the beginning of the heating season, people spend more and more time indoors, but the time to open the window for ventilation is getting shorter and shorter. In a continuous closed space, pollutants in the air will gradually accumulate. At the same time, the unique modern lifestyle also makes the "dangerous" indoor air environment in winter more complicated.
For example, the aromatherapy candles commonly used in life to create a "sense of ceremony" are lit, and the indoor atmosphere becomes romantic and warm; There are also three or two friends and relatives invited to come home and eat around steaming hot pot, which is the most suitable way of life in winter; Of course, there are also many people who rush to clean the whole house and clean and disinfect the inside and outside before the Chinese New Year. However, these familiar daily activities have brought hidden dangers to indoor air quality.
First of all, the burning of open flames and candles will emit pollutants such as PM2.5 and nitrogen dioxide, while improper use of cleaning chemicals will release volatile organic compounds, while it seems harmless to rinse hot pot at home, but everyone who has eaten it knows that the smell may not be scattered all day, and cooking fumes will even be scattered all over the house.
In addition, continuous heating and air conditioning in winter will greatly reduce indoor humidity. Dry air will not only make people thirsty, but also take away moisture from the skin. However, most humidifiers on the market use ultrasonic atomization to humidify, which may bring a lot of scale and bacteria at the same time, thus threatening people's respiratory health.
In winter, the most easily overlooked threat of indoor air pollutants may be formaldehyde. In particular, many people have experienced a summer of renovation and vacant new houses, and are ready to move into warm new houses in winter, but they don't know that formaldehyde may pose a continuous threat to the indoor air environment. Moreover, formaldehyde comes not only from decoration materials, but also from many household items and soft clothes, and its release cycle may be as long as 3- 15 years. When the ambient temperature exceeds 19 degrees Celsius, formaldehyde will start to evaporate at an accelerated rate. In other words, in your new home with heating and no windows, formaldehyde is still quietly released, threatening your health.
Scientifically lay the foundation of "one-stop" air purification solution to ensure respiratory health in winter
Faced with so many hidden dangers and threats, a comprehensive air purification device is naturally an ideal choice for consumers. However, it is not easy to consider the scenes of consumers using air purification equipment and the potential threats they face, and propose targeted solutions.
As an expert in the field of air purification, Dyson is handy. First, thanks to Dyson's profound technical accumulation in the field of air purification; Secondly, the long-term research on indoor and outdoor air quality and consumer insight have enabled Dyson to deeply understand consumers' diverse demands and usage habits, and to formulate targeted solutions, so as to be at the forefront of the air purification industry with a series of core technologies.
Dyson's air purification fan series contains many groundbreaking technologies. Facing the ultra-fine particles that people often mention, Dyson equipped the air purification fan with H 13 HEPA filter, which can purify and lock 99.95% of particles as small as 0. 1 micron. With the activated carbon filter, Dyson can also absorb harmful gases such as odor and volatile organic compounds, and solve the control problem of indoor inhalable particulate matter, odor and volatile organic compounds in winter. In addition, Dyson air purification fan can ensure that the adsorbed pollutants will not flow back to the room by virtue of the sealed design of the whole machine, avoid secondary pollution, and make home activities healthy and safe in winter.
Facing the problem of continuous release of formaldehyde, Dyson's air purification fan is brighter, and its solid formaldehyde sensor can accurately and continuously monitor formaldehyde for 7 years, while avoiding interference from other gases. We should know that the molecule of formaldehyde is less than one fifth of 0. 1 micron, so it is easy to be confused with particulate matter released by gases such as orange peel and alcohol during monitoring, and it is extremely difficult to monitor accurately. On this basis, the catalyst filter screen carried by Dyson air purification fan can continuously capture formaldehyde molecules and decompose them into trace amounts of water and carbon dioxide, and maintain the catalyst activity through the oxygen supply in the air, so formaldehyde can be continuously removed without replacement, which is more convenient.
For the problem of dryness in winter, Dyson's humidified air purification fan PH04 is quite competitive, which can solve the major air hazards in winter and realize clean humidification at the same time. This is due to its built-in ultraviolet sterilization technology, which can kill 99.9% bacteria in water, while the silver fiber evaporator can inhibit 99.9% bacteria growth. With these multiple guarantees, this equipment can provide clean and humid air only by adding tap water.
Not only that, Dyson AirAmplifier airflow multiplication technology can also evenly spread the purified humid air to all corners of the house, so that the uniform high-quality air in the whole house is at your fingertips.
On top of the product, Dyson developed POLAR test to simulate real family scenes.
In order to make the designed products closer to the consumer's usage scenarios, Dyson continues to pay attention to the changes in people's lifestyles and the ever-changing healthy breathing needs. Based on in-depth user insight and research, engineer Dyson found that consumers are accustomed to placing air purification equipment in a corner of the house, not in the center of the room, but what many people ignore is that this usage habit may bring challenges to the unified purification performance of air purification equipment in the whole house.
After discovering the details of users' use, Dyson engineers developed a testing method called Polar (Point Loading and Outdoor Response) in 20 17, aiming at simulating users' real home environment purification needs in a larger indoor space. The experiment was carried out in the laboratory of 8 1 m3. Without installing additional mixed-flow fans, the air purification equipment is placed in a corner, and the air quality data of the whole house is continuously monitored through nine sensors, so as to evaluate the filtering performance, sensing performance and uniform purification effect of the air purification equipment. This test can comprehensively and effectively ensure the cleanliness and health of the whole house air quality in the real family environment.
Based on the accurate monitoring of indoor air quality through multiple sensors, Dyson AirAmplifier airflow multiplication technology can spread the purified air evenly to every corner of the home. The polar test shows that 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 indoor pollutant content is only 0.00000504g/m3.
Moreover, on the basis of POLAR test, Dyson and China Household Electrical Appliances Research Institute (CHEARI) jointly formulated the group standard "Technical Requirements and Test Methods for Intelligent Mode of Air Purifier" in 20 19. In the subsequent revision of the national standard GB/T 1880 1, the extreme method framework was proposed to the drafting group. After verification and revision in many ways, a new automatic control system was finally formed in the national standard GB/T 1880 1-2022 "Air Purifier" promulgated in June this year.
With scientific testing methods and strict technical standards, it is no longer difficult for consumers to choose high-quality products that meet their real needs and usage scenarios, such as Dyson air purification fans. It can be said that Dyson not only launched subversive products to meet the needs of consumers, but also brought "tangible benefits" to consumers by persisting in innovation and leading the development of the industry.
