In recent years, with the continuous improvement of people's living standards, people pay more and more attention to environmental pollution. In recent years, China has also strengthened the prevention and control work and comprehensively accelerated the pace of atmospheric control. According to the "national urban air quality report in August 2020" issued by China environmental monitoring station, in August 2020, the average number of days with excellent air quality in 337 prefecture level and above cities in China was 93.0%, the number of days with mild pollution was 6.6%, the number of days with moderate pollution was 0.3%, and the number of days with severe pollution and above was 0.1%. The average concentration of PM2.5 is 17 μ G / m3, a year-on-year decrease of 15.0%; The average concentration of PM10 is 34 μ G / m3, a year-on-year decrease of 15.0%.
As the "haze panic" slowly dissipates, the demand for formaldehyde removal and TVOC will become the main demand in the whole Air Purifier market. According to the "2019 white paper on indoor air pollution in China", taking the houses that have been decorated for 3 years as the research object, the measurement is carried out at the temperature of 16 ℃ - 38 ℃. Among the 6482 points tested, the unqualified rate is 74%, and only 26% are qualified. The main harmful gases of indoor air pollution are formaldehyde and TVOC (total volatile organic compounds). In 6482 test samples, 4796 points of these two gases exceed the standard, accounting for 97.3% of the total unqualified points. For users, when selecting an air purifier, they should not only consider the purification efficiency of PM2.5, but also monitor indoor VOC pollution. Home Air Purifier units
Recently, ewong launched a new ewong air purifier x, which can not only effectively purify pollutants in the air, but also equipped with a more sensitive VOC sensor, so that the equipment can more accurately detect the content of VOC pollutants in the room, so that users can understand the VOC pollution status in the past period of time and how this product performs. Let's have a look!
Higher end ewong home air purifier units
The products launched by ewong have always been famous for their simple design. Ewong air purifier x still continues the simple design language, but there is a slight change in the appearance design compared with the predecessors. First of all, in terms of modeling design, most of the previous ewong air purifiers used thin and high cylinder modeling design. Our air purifier looks like a fan
The swing of the swing leaf is very flexible and natural. Through the swing leaf, you can see the internal metal net, which can intercept large foreign bodies falling into the air duct. Curious babies at home stretch their fingers in, and Bao parents don't have to worry about cutting their fingers
A circular display screen is equipped on the right side of the grid, and the data switching key and ewongolo are respectively on the top of the screen. Ewong purifier X has only two keys: on / off / gear switching key and data switching key. During daily use, in the shutdown state, briefly press the on / off / gear switching key to start the purifier; In the power on state, press and hold the on / off / gear switching key for 2 seconds to shut down the purifier.
Finally, the huge fan is presented in front of us. The working principle of the air purifier is very simple. The motor and fan in the machine pump the air into the machine. When the air passes through the filter screen, it will remove or adsorb various pollutants. The negative ion generator will ionize the air continuously, produce a large number of negative ions, which are sent out by the micro fan to form a negative ion air flow to achieve cleaning The purpose of purifying air. Ewong air purifier x can output 6660 liters of clean air per minute under three gears, which can efficiently clean indoor air and make breathing more unobstructed.
5 heavy high-precision filtration, strong air purification
Ewong purifier x adopts 5-fold high-precision filtration. Like the alternating seasons of autumn and winter, viruses in the air are increasing day by day. The efficiency of anti-virus coating and antibacterial coating equipped with ewong purifier x exceeds 99.99%, which can effectively purify H1N1 virus, Escherichia coli virus, Golden Grape ball and other bacterial viruses; H13 HEPA filter screen is suitable for 48 square meters, and the particle Cade reaches 400 cubic meters per hour. It can fully filter the nano inhalable pollutants of PM2.5 and aerosol, as well as 80-90 nm bacteria, viruses and other pollutants.
VOC is a volatile organic compound (volatile organic compounds) is the English abbreviation of volatile organic compounds. Indoor VOC mainly includes formaldehyde, ammonia, ethylene glycol, esters and other substances. Most of them are spontaneous combustion products such as coal and natural gas, smoke such as smoking, heating and cooking, and emissions from building and decoration materials, furniture, Household Appliances, cleaners and human body itself. When the VOC in the room reaches a certain concentration, it will lead to pollution It has symptoms such as headache, nausea, vomiting and fatigue. In severe cases, it even causes convulsions and coma, damages the liver, kidney, brain and nervous system, and causes serious consequences such as memory loss.
A sufficient amount of impregnated activated carbon is added to the impregnated activated carbon layer at the bottom of the filter element X of the purifier. The developed pore structure can firmly adsorb gaseous pollutants such as formaldehyde and VOC. The active molecules in the carbon pores can gradually remove some adsorbed formaldehyde to avoid secondary pollution. The formaldehyde Cadr reaches 300 m3 / h and the TVOC Cadr reaches 110 m3 / h.
Xiaobian tested the purification capacity of ewong purifier X. it can be seen that after burning two incense sticks, the PM2.5 value of the living room (30 square meters) has reached 306. After switching the gear to automatic, it can be seen that the PM2.5 value is reduced to 104 after 13 minutes. It can be seen from the curve that the value returns to normal in about 20 minutes
On the app, you can clearly see the change curve of PM2.5 value and VOC value. There is also a small detail on the app interface, and the color of the interface will change according to the change of PM2.5 value. For example, when the air quality is excellent, the interface will display green, and when there is heavy pollution, the interface and keys will turn red
On the app, you can also adjust the operation mode of ewong purifier x, leaf swing angle, turn on / off light and prompt sound, turn on / off child lock, etc. at the same time, you can also turn on negative ions. During work, you can release negative oxygen ions to help remove pollutants in the air, and check the filter element status. A set of filter elements can be used for nearly one year in daily use.
The screen of ewong air purifier x is designed with light sense. The brightness of the screen can be automatically adjusted with the change of light, and the operating noise is as low as 30.7db (a). When used late at night, it not only has no light pollution, but also does not worry about disturbing people's dreams. For families with elderly or children at home, ewong air purifier x can not only reduce indoor PM2.5, but also absorb VOC, making "breathing health" a freedom
