Xiaomi has announced another addition to their Mi Home Ecological Chain, another product that will uplift the lives of many people. Introducing the Mi Air Purifier PRO. This product is quite nostalgic to me, as my thesis back in college is all about Indoor Air Quality, which made it to the HVAC-R Congress in Hong Kong and was able to present my thesis in front of many Air Quality Experts around the world. Taking on this product is indeed an honor for me to walk back to where I came from.
Mi Air Purifier Pro, now on its second generation, adopts the same cleaner with similar double blower motor design, pressurized duct followed, coupled with some duct optimization, this new product CADR reaches 500m3/h, First Gen rates 406m3/h while second generation of 388m3/h, the figure was significantly enhance.
The Mi Air Purfier Pro also had another further upgrade, now with the LED display panel in an circular shape. This bids goodbye to the dependency on the phone to view all the statistics of the air quality inside your room. Now you can check your indoor air quality without needing to turn on your phone and check the Mi Home App anymore.
Mi Air Purifier Pro follow the previous generation purifier filter, and adds RFID recognition on this basis, in a nutshell what you learned through official channels to third-party channels to buy the original screen this identification feature can also avoid resetting the filter, replace the filter by key operation without telling the purifier.
Now with that much improvement, we have seen the price soar up from 699 RMB to 1499 RMB, thats more than 200% price increase, but in return the Mi Air Purifier Pro is currently the most experience and improve air purifier, bigger and faster application area indoor purification efficiency, more accurate particle sensor and of coursed the LED display indoor air monitoring display panel.
If you ask whether its deserving of that price and comparing their own products is not easy to say, because each person's needs and spending power are different. I can only say Mi Pro air purifier with active 2-generation air purifier differential positioning of new products, two who have their own raison d'etre; if it is with the same industry compared to other competing products, Mi Air Purifier Pro still have a clear price advantage, but in fact, I look forward to a 2,000 RMB in a 700CADR performance level models, rather than the basic model with no facelift.
The foregoing is a general description of Mi Pro air purifier, to understand the above information it is possible to determine whether this air purifier can do, but if you do not understand the Mi Air Purifier, read the following review and you will understand the product more.
---- Operating status indicator OLED ----
From the outside, Mi Air Purifier Pro is still the previously controversial Japanese minimalist design, an environment official photos tell it can be integrated into a variety of high-end home design style. However, this Mi Air Purifier Pro on unadorned front has been added to a black circular OLED panel, the design is pretty much simplistic.
Mi Air Purifier Pro Appearance
Mi Air Purifier Pro continuation of previous generation top design, the fan cover is similar to the second-generation non-removable design. There's a second-generation purifiers status lights are all transferred to the OLED display, this is located in the upper part of the fuselage in the display easier to perceive the user than the previous air quality indicator in the bottom of the fuselage layout should be reasonable, and with the top of the fuselage piece OLED light sensor data can also automatically adjust the brightness.
OLED status display
In addition, the back of the fuselage small button you can turn it off completely at night. According to our experience, can show PM2.5 concentration values indoor pollution status, temperature and humidity as well as cleaner and represented by the color mode on this OLED screen displays information distributed in the center of the screen, very compact, perhaps because only the central circular area is due to OLED screens.
Control logics, Mi Air Purifier Pro still press the power button to switch to get through all operating modes of the length, press two seconds switch, short press to switch between automatic sleep mode and favorites. However, perhaps because of our experience and APP are prototypes before the official product launch, I did not find the favorite mode speed control interface Mi APP, so in addition to automatic bits, Mi Air Purifier Pro only can manually switch to the minimum and maximum speed of the two working state, so it will be set in the automatic routine will be the norm.
Mi Home App Application
After trying two generations of Xiaomi based air purifier, Mi Home APP performs the same basic function. But the APP meters within the Mi Air Purifier Pro control experience has been further enhanced, in addition to where you can see the indoor air pollution, temperature and humidity, regulating working conditions, it also shows you some interesting data, such as I boot up half hour of the purifier for me to filter out harmful air at about one-half the size of the 10 hot-air balloon, for I need to breathe 328,000 times. Just some fun stats to know. In addition, APP can also provide similar child lock, the advanced features of interactive smart home scenario, of course, more cases we need is for Mi Air Purifier Pro remote and remote operation
---- Particulate matter detection laser sensor upgrade ----
Laser sensor for detecting the air quality in the rear fuselage
Automatic relies heavily on the accuracy of the air purifier itself particle detector, if monitoring data are not allowed to rely on indoor pollution regulator purifier operating range of automatic settings it does not make sense. According to official statistics meter home, Mi Air Purifier Pro uses a precision of 0.3 micron laser particle sensor, compared to the industry mainstream Infrared revolutionary accuracy improved. But we understand that the final decision is only one of sensor data accuracy condition, it can be detected and measured in the air to enter the number of detector PM2.5 particulate matter less, but how will the results of number concentration of particulate matter into the calibration PM2.5 the concentration of the formula requires "algorithm" involved, even if the algorithm is particulate matter sensor suppliers are unable to provide accurate, so the final decision algorithm to detect concentrations of PM2.5.
According to our tests, Mi Pro air purifier and network selling HW haze table in almost the same position detection PM2.5 concentrations amplitude is not small deviations, of course, our hands no million class professional testing equipment so who can not pinpoint the problem data, which is a common phenomenon throughout the air purification industry, regardless of Mi, Mi Air Purifier Pro laser sensor specifications already better than the vast majority of competing products.
---- Two Fans dual fan power structure regression performance noise reduction ----
Fuselage middle and top of the fuselage has a different set of fans and impeller
Fan duct connection, Mi official information did not do too much narrative, we know that this new generation of cleaner uses a similar millet purifier dual fan dual impeller design, but also with pressurized air structure. From 500CADR and it did not increase the power consumption, size, the Fengyun Japan Nidec custom motor, newly designed and cut wind angle axial fan blades contributed.
500CADR applies to how much space? Storey 2.8 meters per hour, according to the requirements of indoor air in 5 times, the 500 cubic meters per hour, roughly corresponding to the requirements of 35 square meters, if it is larger environment, or the number of air changes per hour from a single serious pollution to the air purification health standards when used will be extended accordingly.
Noise Found
Found Power
Findings show, Mi Air Purifier Pro power consumption of 66 watts maximum wind speed, the noise from the value of 60 dB at 2.5 meters case, performance significantly better than the 82-watt and 70 decibels measured data generation millet purifier, it seems a new fan performance is very good.
---- Filters may use the existing programs ----
Mi Pro air purifier's filter installation with the same generation purifiers, filters limit lever is back, and this will enhance the purification filter system tightness. On the other hand, we do not see the official information about Mi Air Purifier Pro information, I only see the annotation Toray efficient filter material in the bottom of the page Notes area, given the similarity of the mold and the material before it It is likely to be used in millet air purifier 2 H11 grade HEPA filter and activated carbon filter fitted in the circular composite filter layer.

RF tag at the bottom of the fuselage
The only visible change Mi Pro air purifier filters is the addition of RFID recognition, at the bottom of the screen affixed with RFID tags can be used to detect whether they purchased the original product. This will make it hard for someone to sell counterfeit filters to the market.
---- Filtration performance test was stronger than the first generation purifier ----
test environment
Initial concentration and test data
Finally, the only question remaining is the air purification effect, and to this end, we are in a relatively closed 19 square meters, about 49 cubic meters of space simulations particulate matter, the environment and the previous test millet air purifier generation identical. Before the test, we enhance the settling indoor PM2.5 concentrations by smoke and fumes waiting period to 999 micrograms per cubic meter or more, and then open the maximum wind purifiers stall test. When indoor air concentration to be reduced to about 500, we began a numerical record every three minutes.
Mi Pro air purifier purification test results
The purifier according to our previous testing similar methods, we get from 500 to 35 micrograms per cubic cleaning time. In the results, Mi Pro air purifier can be within 15 minutes at 19 meters 49 m3 Environment pm2.5 initial concentration of 509 environmental cleanup to 28, the results show that even in the face of severe haze burst table pollution, Mi Pro air purifier can still quickly and efficiently to the bedroom air purifier national standards for air quality, superior grade, if it is on an even larger living room of 30 square meters, this time will be extended, but compared to other CADR in the following 500 models, Mi Air Purifier Pro will undoubtedly be more performance advantages.
Mi Pro air purifier and air purifier millet generation performance comparison
The test results in a data release I did, the first 13 minutes when the indoor PM2.5 concentration has been controlled to 36, which is very close to our set of 35 micrograms per cubic meter standard line, so it can be seen 12 minutes another three minutes, the concentration of indoor pm2.5 dropping from 40 to 28, said Mingmi home air purifier Pro 30 also retains the low-concentration region has a strong margin performance. Comparative test results generation millet air purifier you will find that this curve has been very smooth nearly 35, which is the performance gap between the performance, not just the table just three minutes difference.
---- Summary & Expectations ----
At the begining I personally thought that the Mi Air Purifier is intended for just bedroom use and no more than that. But as the experiment went on, I saw that the usage of this Air Purifier can be extended to office and conference rooms as long as the square area can be covered by the Mi Air Purfier Pro, its a good compliment for healthy living.
More and more airborne virus and contaminations has been swirling around our air and this nifty product is an cheap solution for a healthy living and longetivity of life. Now we hope that this product can be readily be available to the market as soon as it hits the deck in the Xiaomi Online Store in China.
You can now purchase the Mi Air Purfier Pro for 1499 RMB after November 11 launch.
