With the introduction of the Guidelines for the Assessment of Air Quality in Passenger Cars in 2012, air purification products in vehicles have developed rapidly in China. But after three years of gestation, the car purification products still repeat the shortcut of home version.
A real air purifier for cars has become an urgent need of people. In January, Zhiqu, a creative e-commerce website, officially released the Kamer "Calm" car mounted intelligent air purifier, filling the market gap; In addition, intelligence is integrated into the car scene to make the product more humanized. At present, the author is lucky to get the product. Let's take a look at its specific performance.
Basic parameters
Unpacking
▲ The packaging material is square cardboard, while the black color is slightly dark.
▲ There is the word "Clam Air Purifier" on the front, but it is difficult to associate the word "purifier" with the semicircle figure on the bottom.
▲ The back echoes the front, and the pattern is still the original "semicircle", but the silver "Keep Calm and Carry On" can not help but remind people of the posters made by the British government during World War II. "Keep calm and keep moving forward", which coincides with the design concept of Clam vehicle purifier.
▲ The two sides are the source description of the product.
▲ Pull out the upper cover, and the bottom package is a familiar one, an inverted "upper cover".
▲ "Keep Calm and Carry On" poster in front and back symmetry.
▲ The bottom of the package is the specific information of the related products.
▲ The internal packaging of Calm intelligent vehicle air purifier is also the most elaborate product the author has seen. In terms of color, it is completely different from the black of the packaging box, and the white buffer sponge is particularly conspicuous; The shape of inner circle and outer square also follows the traditional Chinese culture.
▲ As a main body, the purifier can be removed separately, and the accessories are not inferior. Each accessory has an independent packaging bag.
▲ Most consumers will ignore the length of the power cord when purchasing products, but it is undeniable that the length of the power cord is a limiting condition of the product's moving range.
The power cord of the Calm car charger is 2m long. Under the limited environment in the car, the purifier can be placed at will. It will not be unable to be placed in the proper position because the power cord is not long enough.
▲ Although it is positioned as an on-board product, it is not unique. Calm intelligent on-board air purifier is also suitable for home use, so it is also equipped with a separate power adapter. However, the length of the power cord of the power adapter is slightly short, which shows that sidelines are not so valued.
▲ In order to meet the complex environment in the car, the safety bracket, strap and anti-skid mat of the host base are also included.
Examples of use scenarios:
Safety bracket+anti-skid pad of host base
Bandage
▲ The last thing worth mentioning is the manual, which is quite different from the traditional manual. It is a complete red poster, "Keep Calm and Carry On".
▲ The back is the real card type instruction manual, and the front page is a miniature poster. The design concept of the product is perfectly integrated into the product, and users can deeply feel it from unpacking to use.
▲ According to the official publicity, the function of Calm's packaging box is not limited to this. It can be used as a household storage box made of cardboard. The black color matching is not only dirt resistant but also a versatile color. It is very creative, but it does not rule out that there are references to "Solo One".
Appearance&Structure&Workmanship
▲ As a vehicle mounted product, the volume of Calm intelligent vehicle mounted air purifier is well controlled (Φ 195 × 63mm), and the disc shape can better adapt to various corner environments than the square design.
▲ The top of the product is a convex disc shaped filter maintenance cover, which is processed by concentric circle wire drawing and has a strong metal texture.
▲ The depression around the maintenance cover is the air inlet of the purifier, and the edge of the mirror treatment corresponds to the protective cover of the metal wire drawing.
▲ It may be due to cost control that the main engine is made of ABS plastic. Round dents make the product have a strong sense of hierarchy.
▲ There is a grille air outlet on the front. The aperture of the grille is small, which can effectively prevent children's fingers from entering the machine by mistake.
▲ There is a solid key "shape" and a bar indicator above the grid. The key is not a real key, but an inductive touch key. Compared with the solid key, it has a longer service life and more sensitive control. This design should be better for users to understand and be clear at a glance.
▲ In the power on state, the indicator light has different colors according to each use scenario (). In the dark state, the light is weak and will not cause light pollution.
▲ There is a metal outer ring at the bottom of the product, and the color matching with the maintenance cover here determines the color type of the product (champagne gold+deep space gray).
▲ The product base is a piece of translucent polymer material. The three soft silicone feet can not only provide sufficient friction, but also effectively reduce the vibration generated by the purifier during operation.
▲ The left side is the power interface and the physical power button. In order to facilitate sorting, the power line buckle and the safety bracket buckle are placed at the bottom of the product.
▲ The middle part is the power consumption information of the vehicle mounted safety buckle purifier.
▲ According to the identification on the upper end of the maintenance cover, it can be opened by turning it counterclockwise. For safety, opening the upper cover fan will automatically stop working.
▲ The Calm intelligent vehicle mounted air purifier uses a composite HEPA filter screen inside, which is also a common practice for commercial air purifiers.
▲ The upper layer is MarkromolekuHEPA filter screen, which intercepts and filters fine dust, pollen, smoke, bacteria and virus, effectively inhibiting bacteria, mold, virus and other allergens.
▲ The lower layer is a catalytic activated carbon filter screen, which uses a common honeycomb structure to absorb harmful volatile gases such as ammonia, formaldehyde, sulfur, acids and VOC.
▲ The purifier adopts high-performance DC motor, combined with the turbine shaped air duct design structure, to ensure stable operation.
Use&Software
The use of Calm intelligent vehicle air purifier can be described as a fool's type, without too much operation. Manually turn on the physical power switch at the bottom and the control button at the top to adjust the air volume.
▲ As an intelligent product, the purifier can also be controlled by the software on the mobile end. The APP is mainly used as a remote switch and digital display of environmental status. More advanced mode selection also needs to be completed on the software end. The lightweight route of the software itself is also obvious, and it can be used without registration.
▲ Enter the software, connect with the purifier via Bluetooth on the setting interface, and intuitively understand the service life of the current filter here.
▲ In the status main interface, you can intuitively understand the current environmental status, temperature PM2.5、 Carbon monoxide, electricity and other information. So far, PM2.5、 Carbon monoxide and other components are still displayed in grades, and specific values are not supported.
▲ By default, it is the on-board mode, and the home mode, sleep mode and timing mode are available for selection. Both the on-board mode and the home mode can be adjusted by pressing the control button on the top of the machine briefly; In the sleep mode, the minimum wind force must not be manually adjusted. More important is the timing mode. Users can set the start time through the mobile app. Since the air volume is the largest in this mode, the maximum working time for a single time is 30 minutes in order to save energy.
▲ For the embarrassment of bacteria breeding in the car caused by long-time use, Calm intelligent on-board air purifier has a special function of active oxygen sterilization. In this mode, the active oxygen generator needs to be activated and the air volume is the largest. Therefore, when this mode is running, it must be opened remotely, but in an emergency, it can be closed by manually pressing the control button on the top of the machine.
▲ The software will build Zhiqu into it, giving geek users more digital options.
Purification efficiency test
▲ Calm intelligent on-board air purifier only took 6 minutes to restore the indoor air to a fresh state, and the measured data is satisfactory (because the test space is very small, it has a certain impact on the test results).
Comprehensive test
noise
In order to help users better understand the measured data, the corresponding relationship between the decibel value and the actual auditory perception was found in the network.
▲ As an on-board product, in the on-board mode, the noise of the purifier in the third gear wind is 47 dB, 59 dB and 65 dB respectively, and the current ambient noise is 40 dB. The zero distance test with the highest noise is selected for this test, so the measured data is larger than the official data. In order to provide comprehensive data, the author "risked his life" to measure that the noise under the active oxygen sterilization mode was 110 decibels, and the alarm sound was obvious, which could effectively alert users.
wind speed
▲ The Calm intelligent vehicle air purifier has a three gear wind force. The wind force is not large in the first gear and the second gear. Even in the third gear violent mode, it can be seen that Calm is walking a gentle path.
power waste
For an on-board product, power consumption is not so important. The maximum power of the purifier is 9W, the battery capacity is 3.7V/5000mAH, and the working time under the maximum power can be calculated to be about 2h. In the limited space of the car and the environment without lack of power supply, 2h working time is enough to complete the purification work.
summary
For an on-board air purifier with a turbo fan, the internal air circulation is faster in the limited interior space. Calm intelligent vehicle air purifier also uses a multi in one filter screen, which is not only convenient for users to take care of, but also can effectively filter and decompose various harmful substances.
The simple and fashionable disc shape and compact volume enable Kamer to adapt to various complex environments, and finally integrate the intelligent system and the active oxidation function of large purifier to improve the cost performance ratio.
In order to further improve the user experience, the author expects the Calm purifier to further optimize the software part and provide more functions, digital air status and Bluetooth manual connection. Finally, the price problem that users most care about is the price of 999, which is currently on sale on Zhiqu. com.
