[PConline Professional Review] Are we breathing air that is a fatal chronic killer? Air pollution is unavoidable. Now that young families purchase new homes for renovation, they produce a lot of harmful gases such as formaldehyde and benzene, which increases the incidence of asthma in children. Medical research also proves that the benzene and some unknown gases in the decoration materials are related to the occurrence of leukemia. Coupled with the outdoor particulate matter in the air, will be transmitted to the interior with the air, the same harm to the human body can not be underestimated.
The Xiaobian share with everyone is Samsung's original imported KJ720F-K7586WF air purifier, Samsung's high-end air purifier, the indicators are better than the new national standard for air purifiers. The CADR value of particles can reach up to 720m3/h, and the CADR value of formaldehyde can reach 100m3/h. The large space within 86 square meters can be quickly and easily cleaned. The filter's service life, CCM value (cumulative purification) as high as 189000mg, is 15.7 times the new national standard P4 level, to bring long-term protection for the user.
â— appearance and details
Samsung's Air Purifier Blue Whirlwind series, which was launched in 2016, uses family-based Facebook design. Not only beautiful and humanized, but also can effectively improve the effect of purifying the polluting gas. The pillar-shaped body is simple and elegant, and the white body fits all kinds of decoration styles without losing the elegance and elegance. The area of ​​the air inlet directly affects the performance of the air purifier, while the Samsung air purifier uses a front snowflake-shaped air inlet, which is not only beautiful, but also ensures the maximum air intake area.
The slender body does not occupy the home, and the air purifier can also be placed against the wall. Samsung's air purifier adopts a three-dimensional three-dimensional air outlet design, which is not only an oblique design of three air outlets, but also air outlets on both sides of the airframe to achieve the “throwing†of clean air to the upper side to achieve an increase in indoor air circulation efficiency.
Samsung designers also take full account of families with children who are curious about new things and may try to climb onto an air purifier or reach out into the air outlet to pose a danger. The bottom of the Samsung Air Purifier uses an outwardly extending curved surface design that is more stable at the bottom and cannot be easily knocked over. The snowflake-shaped air inlet is designed to be very small. Not only can a baby's finger fail to pass, but even chopsticks can't be inserted. Undoubtedly, it can effectively protect your baby and keep your baby free.
The top of the fuselage is the outlet and the touch control button area. The elegant corrugated outlet design is not only beautiful, it can output clean air along the way of leaning forward, and speed up the health and fresh air conveyor to every corner.
The touch buttons are quite sensitive, and the touch can be controlled and accompanied by a prompt tone alert. Virusdoctor achieves ultra-clean 3 ion clusters and patented sterilization technology. It can effectively remove bacteria in the air, effectively protect the respiratory safety of family members, protect them from all kinds of bacteria, and create a healthy and clean air environment. Not only that, but also through the display area to clearly identify the current changes in air quality, provide PM10, PM2.5 real-time numerical display and odor color indication.
Xiao Bian will find when testing other air purifiers, most air purifiers use an outlet design, while the Samsung air purifier uses the top and air outlets on both sides of the fuselage. The advantage of this is that clean air can quickly penetrate every room in the room. Of course, it also benefited from Samsung's strong air-driven fan.
The right side of the fuselage equipped with PM2.5 / PM10 / smell three sensors, and can be independently displayed, the user only need to be able to judge the air quality values ​​and light changes. It is also possible to remotely observe changes in indoor air through the mobile phone APP. PM2.5 and PM10 provide numerical changes and six color logos. These six color logos correspond to the air quality index AQI grades and colors issued by the country, while odor detection provides four color change logos.
The six color logos are graded with the national air quality index AQI.
The handle is located on the back and bottom of the fuselage. The depth of the handle is just right. The user can easily move the machine to the space that needs to be cleaned.
Summary: Samsung's air purifier in the appearance of the model to experience the designer's intentions everywhere, the use of three-dimensional three-dimensional wind design, improve the efficiency of indoor air purifiers. The simple and clear design avoids the visual fatigue of the consumer. The snowflake inlet design not only looks good but also increases the intake area. The PM2.5, PM10, and Odor three sensors can be independently displayed on the top display area, allowing users to clearly identify indoor air quality.

Because it is equipped with three sensors, PM2.5, PM10 and odor, it can be displayed independently on the APP. When the indoor air is poor, the air purifier can also be turned on in a timely manner to purify the air, allowing the family to feel more comfortable breathing.
â— Purifier filter system dismantling
Samsung's air purifiers are equipped with multiple filters and are equipped with a five-filter technology that can effectively filter floating air, formaldehyde, and dust in the air to achieve the overall purification of the living room air. Different from the market's emptiness, it adopts HEPA filter and electrostatic device to make this air-purifying and long-term efficient purification. Multiple filter layers filter to effectively prevent indoor formaldehyde threats. More intimate is the Samsung air purifier taking into account the needs of different environments, the pre-filter is also equipped with a soot filter.
Dismantling the video:
Pre-filter
The pre-filter can effectively filter the dust with a particle size of >5 μm, and can filter large dust particles and hair in the air, so that the lifetime of the subsequent filter can be guaranteed.
Soot filter
Designers of Samsung Air Purifier, considering that many families now use open kitchen design, in order to absorb the oil in the air when the cooking food is designed to filter the filter.
Electrostatic device
Samsung's air purifiers not only use HEPA integrated filter, but also equipped with electrostatic precipitator, it can make the dust particles with a little more easy to be a regular adsorption of the dust filter, can greatly improve the particulate CCM, extend the filter Service life. Of course, this kind of filter can also be washed by water, so that it can ensure high adsorption capacity for a long time.
Integrated filter
Through-hole structure is adopted, and plastic honeycomb is used as a skeleton to load activated carbon with a large specific surface area onto the grid. The huge specific surface area of ​​activated carbon can efficiently adsorb harmful gases. Adsorption of volatile organic compounds such as formaldehyde, toluene, hydrogen sulfide, chlorobenzene and other organic gases and malodorous gases, as well as low-concentration, high-volume air pollutants containing trace amounts of heavy metals.
HEPA filter performance is an important measure of purification capacity, not only to consider the filter capacity, but also weigh wind resistance performance. The HEPA filter used by Samsung's air purifier can effectively filter tiny particles and effectively filter pollen, dust mites, and PM2.5 particles.
Fan motor core
After dismantling all the screens, you can see the upper and lower parts, equipped with two stepless variable speed fans. Such a fan not only brings more powerful power, but also reduces noise and the power consumption during operation will be lower.
Summary: Samsung's air purifier uses multiple filter technology to ensure that it can purify indoor air pollution. The most special place is the use of electrostatic devices and integrated filter double combination, not only can ensure the adsorption of particles and bring more efficient CCM value, but also provide deodorization and removal of formaldehyde in activated carbon filter, greatly enhance the capacity of air purifier .
â— purification capacity test
Ordinary home indoor purification effect is the key to determine the quality of air purifiers, this time we choose 25 square simulated home environment for testing. After igniting four cigarettes in a closed room to make it fully burned, second-hand cigarettes fill the room. Using the tester to test the PM2.5 index in the air, PM2.5 was measured every 10 minutes to check the time effect of this air purifier at different times.
After the cigarette burned, the odor diffused into the room. Using the air quality tester, the indoor air pollution index found that PM2.5 was as high as 1480, which was a very heavy pollution level. When Xiao Bian entered the test room, he felt that breathing was not smooth, the air was very turbid, and smoke could clearly be seen everywhere.
Turn on the air purifier for testing
The air purifier was turned on, and the wind speed was adjusted to the fast gear mode for the purifying test. After every 10 minutes, the test was performed in a simulated home environment. After ten minutes, it was surprisingly discovered that Samsung's air purifier has filtered most of the pollutants in the room, and the purification effect is more pronounced than other similar products. Its purification effect is also visible.
Twenty minutes later, Xiao Bian entered the room again and could not smell the smoky smell of cigarettes. As a result, the indoor air also became fresh. It was found that the indoor air had reached a healthy level through the detection equipment.
Summary: It can be seen from the above picture that the dirty air in the room that has been used for only 20 minutes has been purified and the Xiaobian entered the room again, and the taste of the cigarette burned away. In general, the purification efficiency of Samsung's air purifier is excellent. Comparing with Xiao Bian’s previous product evaluation, the product has been particularly effective in this aspect.
â— Air volume and noise test
Air volume test
Next, we will test the wind speed and use four stalls respectively to measure the wind speed, which will determine the CADR important factors of the purifier. It has become one of the indicators of purification ability. Samsung's air purifier adopts a three-dimensional three-dimensional air outlet design of the front panel air intake, the top and the sides of the fuselage, and the diagonal design of the upper air outlet is more capable of “throwing†the clean air upwards and improving the indoor air circulation. effectiveness.
Wind speed 2.0m/s Wind speed 3.06m/s 
Strong wind speed 4.47m/s Fast wind speed 5.0m/s 
Wind speed 2.18m/s Wind speed 3.94m/s 
Strong wind speed 5.87m/s Fast wind speed 6.04m/s Noise test
Many consumers want their products to be as silent as possible, especially when they need to be muted at night, and they can filter without affecting normal nighttime sleep. This time we also selected five gears (including sleep mode) to test the noise status of the air purifier in the 36dB environment.
Samsung KJ720F-K7586 noise test
Mute stall noise 36.1db (test chamber test only 29db) weak wind stall noise 41.5db 
Stroke stall noise 50.7db Strong wind stall noise 54.9db 
Fast gear noise 55.9db Summary: Samsung's air purifier has two powerful fan components and no matter whether the low-middle or high-end position has a mute design, the performance in the noise test quite surprised the small series, especially in the silent mode, basically did not feel the noise of the machine. Since the test environment is around 36 dB, the maximum noise measured by the Samsung Air Purifier in the experimental cabin is only 29 dB. The user turns on this gear in the evening to ensure a good night's sleep while achieving clean air.
â— Power consumption test
The air purifier must be used for a long time, so the power used is particularly concerned. This time we have selected four gears for testing. We also deliberately watch the instantaneous power when it is working in standby mode.
Standby stall power consumption 3.7W weak wind stall power consumption 29.89w 
Stroke stall power consumption 54.35 Strong wind stall power consumption 103.26w 
Fast stall power consumption 113.00w Full text summary: Samsung's air purifier uses white simple color, with champagne gold as embellishment. The use of three-dimensional three-dimensional wind design to improve the efficiency of indoor air purifiers. Equipped with three air quality sensors, it can remind users of air quality changes through color lights and values. Effectively purify indoor air through multi-layer filters, unique electrostatic devices and integrated filter double combination, both to ensure that the filter has a long life and can efficiently absorb particulate matter and other harmful substances. In the purifying capacity test, less than 20 minutes can clean the indoor air. At the same time, the ultra-quiet design has surprised Xiao Bian. The big brands have good after-sales services and eliminated the situation of replacing the filters in the future. It is definitely a high-end air purifier with internal and external filters.
