Mi air purifier 2 is launched on November 24, 2015, it can be considered as the upgrade generation of the earlier Generation 1. Compared to the Gen 1 model, the biggest change was undoubtedly in its volume on a smaller foot-print, but also less space occupied. Mi air purifier Gen 2 is targeted mainly for small apartment users which can provide for purification area of 23-48 m².
It houses a solitary electric motor, twin booster fans (which detoxifies at an effective variety of up to 39.6m²), The design of the Mi Air Purifier 2 was inspired by aircraft engines and comes with an anti-formaldehyde enhanced filter that's replaceable. It also filters 99.99% of PM 2.5 particles and up to 92% of formaldehyde (a colorless, flammable, strong-smelling chemical that is used in building materials and to produce many household products).
Xiaomi says the more compact design is made possible by a new single-motor, dual-fan design, which has enabled it to shrink its dimensions by up to 40 percent over its predecessor. However, its smaller size means that Air Purifier 2 has had to take a slight performance hit compared to the predecessor's dual-motor design. Its Clean Air Delivery Rate (CADR), or the amount of air it cleans per minute, is now 330m³/h in standard mode, compared to the 406m³/h for the larger model.
Still, this can go up to 388m³/h in Turbo mode and Xiaomi says it can filter the air in a 23m² room in only 10 minutes.
In addition to the smaller foot-print compared to Gen-1, some optimization was also done to the motor, dual-fan blower motor design in Gen-1 is now reduced to single fan motor in Gen-2, this also allowed energy saving of 58% compared to Gen-2.
The above chart shows the different recommended room areas for different CADR value, so that air can be purified efficiently by the air purifier.
In the purification capacity, CADR is now 330 m³ per hour for standard mode, and in the turbo mode CADR is 388 m³ per hour, clean up area from 27.2 - 46.6 m² (292 - 500 ft²), it takes 10 minutes to complete a purification process once for a 23 m² (250 ft²) room.The firm additionally urges that the Air Purifier 2 is substantially more power efficient – 58 percent even more power efficient.
The company states that the newly improved device is now 11 percent quieter than in the first generation AP, and also makes merely 30db of noise when switched over to sleep mode.
The indicator LED is placed at 7.5cm from the ground, just to low enough to avoid the light interference when reading on the sofa or resting in bed. The light sensor can be adjusted according to the indoor light LED brightness, the indicator can also be completely off.
Mi air purifier 2 is an intelligent air purifier with a WiFi connection to the phone, you can use Mi Smart Home App for live view of indoor air quality changes at home and will base on bedroom area to adjust according to the most appropriate mode of operation. It is smart enough to learn the user's habits, such as automatically adjusted to sleep mode before you go to sleep, and to automatically shut down when they go out.
