Xiaomi is going farther and farther on the road of smart home. A few days ago, it launched its own air purifier. Our machine testing room also got a prototype at the first time. Now let's have a look.
parameter
Size: 735 * 260 * 260 mm
Filter element diameter: 293 * 200 * 200 mm
Power cord length: 1.8 m
Purification efficiency (CADR value): 406 m3/h
Purification area: 28.4-48.7 m2
Power: 15-75 W
Other configurations: wifi、 Light sensor, air quality sensor
Packaging and unpacking
The package is Xiaomi's classic kraft paper, with logo on the front and parameter stickers on one side.
There was an envelope in the foam box with the slogan "Beautiful things" on it.
The manual, guide and warranty are all in it.
Appearance and workmanship
In addition to the foam frame, the purifier has a layer of cloth bag.
The nameplate of the purifier and the logo of Xiaomi can be seen at the bottom opening.
Rounded rectangular cuboid shape. There is only one logo on the front. The slots on the left and right upper sides can be used as handles. The frosted shell feels good.
The top is the air outlet grille of the fan, and the app QR code is stuck in the middle.
On the top right is the indicator light, power key and light sensor (the one on the far right).
There are also air outlet grilles at the handles on both sides.
The lower part of the purifier is a complete air inlet mesh, and the official parameter is 5732
The upper back is the indicator switch and the protective cover of the air quality sensor.
At the bottom of the back is a huge cover plate, and inside is the filter cartridge and power cable box.
The power cord is placed exquisitely, and the material of the power cord is quite soft.
Instructions for replacing the filter cartridge are printed on the cover plate.
Push the lower lever to the left to release the filter cartridge.
The lever controls the height of the bottom platform to fix the filter cartridge.
The side of the filter cartridge cavity is mesh, and the top is air outlet grille. The internal vertical slice is actually the blade of the backward tilting centrifugal fan. Although the blade is noisy, it has high efficiency and generates extremely large wind pressure.
Filter cartridge
The filter cartridge is covered with film, and the front is the "nameplate" of the cartridge.
The top is the handle, the bottom is sealed and printed with the logo, and the top is engraved with the life of the filter cartridge.
The outer layer of the filter cartridge is PET (saturated polyester) mesh, which is used to isolate large suspended solids such as hair and fine chips.
The filter screen is folded through 161 layers and finally bonded into a hollow barrel. The filter screen is HEPA (high-efficiency air particle filter screen), and the developed length is 7m. It is used to adsorb PM2.5, PM0.3, pollen and other inhalable particles. The effective filtration rate of Guanxuan PM0.3 reaches 99.3%.
The coconut shell activated carbon officially publicized is in the innermost layer, invisible... The function of activated carbon is to adsorb inorganic harmful gases such as formaldehyde, benzene, ammonia, etc.
To facilitate cleaning, the fan at the air outlet can also be turned on. Turn the grille to open the top grille.
Unscrew the fixed cover of the top fan to take out the fan blades.
There are grids around the rotor blades for protection/isolation, and the official 4 air ducts can be seen at the bottom.
