Xiaomi air purifier 2 reviews. stages optimized to the maximum possible limit
Xiaomi Mi Air Purifier 2 is the second modification of the air purifier from Xiaomi. This device is part of the Xiaomi smart home product line, so naturally it has WiFi and can be controlled from the app. However, the application serves more to convey information about environment, and the main function of Mi Air is controlled by a single button. But let's take everything in order.
I think it’s worth starting with the fact that Xiaomi Mi Air Purifier 2 is not officially delivered to Russia and was primarily created for the Chinese market, but when I posted a photo of Mi Air in Instagram- it turned out that many of my friends already know about its existence and have been thinking about buying it for a long time, so I spent the first days describing my first impression to my friends. And, looking ahead, I’ll say that Xiaomi was again pleased.
This is not a small gadget, half a meter high and a quarter meter wide, so there were concerns about shipping from China.
However, delivery bypassing Russian mail using Priority Direct Mail, that is, by courier to an apartment in Moscow, was free (which is rare for such a large package), so the risks were significantly reduced. And, soon, I received my box.
The delivery set is quite simple: cleaner, cable, filter and instructions.
A separate story came out with a cable, which came with a three-plug socket for which I didn’t even have an adapter.
However, another standard of connectors came to the rescue - in the purifier itself (where the power is inserted) there was a painfully familiar connector and the solution came instantly.
It is not difficult to guess that this is a regular cable that plugs into the power supply of most laptops. (Including I recommend ordering the right cable right away for $1.62). And, finally, everything worked.
The cleaner looks very presentable: good materials, light colors and thoughtful minimalist design - do their job. At the bottom there are holes through which air is sucked in, and on the lid there is a large fan.
Immediately on the lid is the main button to control the cleaner. With its help, the cleaner starts work, and if you press it a little longer, it ends the job. It is also designed to switch to one of the three modes:
- Automatic (analyzes the air and automatically increases or decreases the fan speed)
- Night (works in the most quiet mode, almost silently)
- Favorite (you can manually program the speed/noise using the app)
That's all well and good, but what does this purifier do?
The main functions of this device are far from design and convenience, but air purification from harmful gases and small particles.The purifier is able to carry through itself up to 380 cubic meters of air every hour and it will be enough to purify the air in the room up to 46.6 square meters. At the same time, it is able to independently and in real time monitor the state of the environment and automatically adjust the speed of work. So that not only he himself knows about the state of the air - an indicator is lit on the front panel, which can light up red, yellow and green, depending on the state of the air.
Of the practical properties, the manufacturer claims:
- Removing odors after smoking
- Removing dust from the air
- Formaldehyde removal
In general, it leaves only clean air, which is good for the health of all the inhabitants of the house or office.
As for the filter, it is very easy to get it by opening the back cover of the purifier. On the inside of this cover, you can read the instructions for replacing this filter.
By the way, when the time comes to change the filter (after 6 months), the indicator on the rear panel will report this. And in the application you can always see how many days are left until the filter is replaced.
Appendix
In order to connect to Mi Air, you need to download the MiHome application (Android or iOS). After downloading the application, you need to connect to the WiFi that Xiaomi Mi Air Purifier 2 distributes and add a new device to MiHome, following the steps suggested by the application. As a result, a new application will appear on your device, which will be called the way you called your Mi Air - I have it Dronk Air
Entering this application, we will see the main interface and the conditional number of the state of the air.
In addition to managing the basic functions (on/off/switching modes) - in the application you can see the air temperature in the room, humidity, condition assessment (it can be from humid to excellent), your location (if allowed) and how many days the filter has left to work.
Useful additional features:
1. Child protection (that is, all buttons on the filter itself will stop working if activated)
2. Yes detailed instructions with pictures in the section about the device
3. Updating the firmware of the purifier with a single button (updated in 2-3 minutes, taking into account the reboot of the device)
4. Timer for automatic on and off (you can only blow air when someone is at home)
5. Turn off all sound signals if annoying
6. Turning off the light indications so as not to interfere
And a few more little things. The application is frequently updated and something new appears periodically.
findings
To appearance absolutely no complaints. This is a very beautiful device that can decorate any home. But it is important to find a suitable place for him so that there is enough space on the sides and in front (10-20cm) to suck in air.As for the application, sometimes you can still find hieroglyphs there and it’s completely impossible to meet a Russian word, but this does not prevent you from using Mi Air at all. To understand the interfaces, it is enough to know the basics of the English language, but otherwise everything is very simple and intuitive.
I can’t say for sure that with the help of this gadget, health will improve significantly, but the absence of dust in the air and the general awareness that the air in my apartment will be passed through a filter gives hope that this year we will breathe better. From the first noticeable sensations (perhaps not related to the operation of the device, but simply due to other factors) - the bedroom is now not so stuffy and it has become more comfortable to sleep. But, in any case, summer is coming on the street, which means there will be a lot of road dust in the air and Xiaomi Mi Air Purifier 2 is designed to save us from it. Soon we will find out what and how intensively our filter is clogged, but it is already clear that either our filter or our lungs are clogged with this. Perhaps let better filter. :)
And lastly, I bought a filter on GearBest for
Hello, friends
introduction
I looked at this device for quite a long time, first of all, I was bribed by a fairly affordable price for such a class of devices - at the level of manufacturers unknown to me such as ZENET, STEBA and others that are present in local stores, and many times cheaper than more advanced air washers - prices for which start at around $500
The principle of operation is that the fan of the device drives the air through a special filter, thus cleaning it from fine dust particles - PM2.5.
Many articles have been written about the harm of these particles, for example, smart Chinese, who have long understood what danger these particles represent - have long been monitoring their level in the atmosphere, like a weather forecast. Here is an excerpt from one of these articles under the spoiler -
Spoiler
PM2.5 is particulate matter less than 2.5 microns in size. Their diameter is 30 times smaller than the diameter of a human hair. These include a mixture of dust particles, ash, soot, as well as sulfates and nitrates suspended in the air. It is these substances that cause clouding of the air, typical for the centers of the largest metropolitan areas.
PM2.5 particles can travel deep into the airways and settle in the lungs. Inhalation of these particles can cause irritation to the eyes, nose, throat, or lungs, as well as bouts of coughing, runny nose, and choking. But this does not exhaust the danger of their impact. The World Health Organization standard for PM2.5 particles is 25 micrograms per cubic meter. Exceeding this limit can disrupt the normal functioning of the lungs and cause the development of many dangerous diseases, such as lung cancer, respiratory infections and cardiovascular diseases. According to a report published in the US in 2010, PM2.5 particles are responsible for the premature deaths of 7,300 to 11,000 Californians annually.
Where can I buy?
Delivery and unpackingThe delivery took place almost as usual, like all other parcels, except that the parcel hung at the sorting center of the delivery service a little longer than usual. Just in case, I called hotline- and on the same day the parcel was brought to the house by a courier.
The box is rather big, 58 cm high, for scale I put an ordinary stool next to it.
There is a sticker on the box for information about overall dimensions- 29*29*58 cm, maximum power consumption 31 watts, weight 6.2 kg, operating voltage 100 - 240 V.
This cardboard box, as opposed to, for example, ceiling lamp- where inside there was another, white beautiful packaging, for the cleaner it is the only and main one. Inside, under the cover is a foam seal and the device itself.
Appearance, dimensions
Dimensions of the cleaner without box - 52*24*24 cm.

The lower part of the case has perforations - a lot of holes through which air is taken in for cleaning
In the upper part there is a fan, which occupies almost the entire surface area, which provides draft and ejection of purified air upwards. Also on the top is a device control button.
In the upper part of the frontal surface there are indicators of the operating modes of the device - Auto, Sleep mode and Favorites.
There are also perforations on the right and left sides, but occupying a slightly smaller area than on the front.
On the back there is a removable cover that gives access to the internal compartment with an air filter.
Above the cover there is a button for resetting the filter - this means resetting its state to 100% when installing a new one, and the cover behind which there is a dust sensor, which are also periodically suggested to be cleaned.

Air filter
During transportation, in the inner compartment, in addition to the filter, there is also an instruction manual and a power cable.
On the inside of the cover, in Chinese, but in clear pictures, the process of replacing the air filter and cleaning the dust sensor is shown.
The air filter has a diameter of 20 and a height of 30 cm

The filter has a multilayer structure - the outer part is close-up
Inner part
Power cable
Gray cable, length - 6 feet, approximately 1.8 meters
Plug - Type I, triple - Chinese-Australian-New Zealand.
But on the other hand, there is a relatively standard triple connector, which is often found, for example, when connected to laptop power supplies. I found the right cable in my stash
Which fits perfectly with the purifier - eliminating the need to change the plug on the native cable
Although for me personally - there is no need for this, thanks to extension cords from Xiaomi - using which I do not have to think about whether the plug will fit or not.
Fan
During normal operation in automatic mode and in sleep mode (the fan rotates in all modes, except for the off mode), the noise of the engine and fan is completely inaudible.
By the way, if you look from the inside, you can see that the fan is dual
When the concentration of dust in the air rises, or when forced into forced mode, air noise is heard, at a maximum comparable to the operation of a robotic vacuum cleaner, only the air noise prevails, and not the engine.
Software
To work with the cleaner, we need the same application - Mi Home. After switching on, the device is automatically detected and connected to the system. The connection process is standard, I won’t describe it again, I’ll just say that in the general list of devices in the Mi Home application - the Grid View display mode - which I call “Remote Control for UD” - information about the level of pollution is displayed in the purifier square. 600 PM2.5 - I didn’t put it in the cement shop, it was such a value out of the box.
Scrolling below you can see the temperature and humidity, climate comfort and air quality rating, the number of days until the filter is changed and the location. It also contains information on the amount of purified air. The menu contains settings - operating instructions, filter reset (analogue of a button on the back), notification of incorrect operation of the cleaner, sound accompaniment of actions, brightness level or turning off the LEDs. It is possible to disable hardware buttons - from children, and control the device only from the application.
 |  |  |
In the advanced settings menu, you can rename the device, give it access from another account, determine the room in which it is located, enable / disable the tray icon, check for updates, etc.
In scenarios, the device can work as a condition, the options are not translated here, the first pair is humidity - less than and more than the set value, the second is the number of detected particles PM 2.5 - less and more than the set limit. As actions, you can set the on, off, sleep, automatic or favorites mode.
The power consumed by the device - from 1.5 watts in standby mode to 28 watts at full power - in Favorites mode 34-37 sq.m. Working in automatic mode - the power is regulated depending on the degree of contamination.

The plugin can be Russified, I use translation plugins Opel(with w3bsit3-dns.com) which are
The work of the purifier
The purifier has been working for me for more than a week, in automatic mode, in the smart home scenarios, the transition to sleep mode at 22:30 and the exit from it at 6:00 on weekdays and 8:30 on weekends is registered. Also, the cleaner automatically turns off when the window is opened - the opening sensor. It reacts adequately to pollution when I expanded the recess for the socket in order to install another Aqara switch, which raised dust - reacted to it by turning on cleaning at increased power.
As of this time, 5% of the filter has been used up, worked for 149.2 hours, which is equivalent to being in some Chinese forest for 6.2 days, and cleaned 5585 cubic meters of air, which can fill almost 2 balloons.
 |  |  |
Externally, according to the filter - no traces of use are visible at all
Has the air become cleaner - at least in terms of the purifier - yes, from a level in the region of 40-50 PM2.5 - it lowers to a value of 10-15. Has there been less dust - due to the condition of the furniture? Not particularly noticeable, the dust as it was about the same and remained. Subjectively - it has become easier to breathe, although this may be the effect of self-hypnosis - although a constantly running fan mixes the air in the room, it becomes noticeably cooler with intensive work.
This is where I will complete my review, except that I will add that the device does not work with the Domoticz system, but this is not necessary in principle - the cleaner works in automatic mode, I just added a shutdown when the window is opened.

A universal solution that is suitable for all versions of Xiaomi Mi Air Purifier. Three filters are assembled in one housing, the task of which is to purify the air in rooms of any type.
High quality activated carbon made with coconut fibres.
EPA filter element, the principle of which is based on modern nanotechnology.
Preliminary cleaning, which does not allow the penetration of large flying particles into the device. The type of operation of which is based on modern nanotechnology.
3 stages optimized to the maximum possible limit
The effectiveness of the replacement cartridge is possible thanks to a well-thought-out filtration system that combines three stages of cleaning. The 360˚ circular retraction ensures high performance, while the three-stage filtration guarantees perfectly clean air at the outlet of the device.
Removes all unnecessary, leaving only the gases necessary for breathing
A wide 360˚ suction angle allows you to create a large area filter element - the special EPA material bent into an accordion traps any volatile impurities.
Soot and dust
Wool and hair
Small sawdust and shavings
EPA cleaning element eliminates all particulate matter in the air
The unique material, plus a special manufacturing technology of the filter element, made it possible to effectively deal with heavy microscopic particles. It traps literally everything that can get stuck in its microscopic structure, and at the same time practically does not slow down the flow, ensuring its instant cleaning.
Removes PM 2.5 particles
Eliminates impurities PM 0.3-0.5
Great for weeding out pollen
Activated charcoal eliminates formaldehyde and odors
The effectiveness of carbon decontamination lies in three points. Granules, in the form of which activated carbon is presented, have a large absorption area, a developed microporous structure and enhanced adsorbing characteristics. This is an excellent tool for removing substances harmful to humans.
Removes formaldehyde and other volatile substances harmful to human health
Adsorbs unpleasant odors from toilet and bathroom
Eliminates kitchen odors, including household waste odors
Real-time status monitoring and notification of upcoming element replacement
Such technologies are already becoming commonplace today - first of all, this convenience allows you to control the constant availability clean air indoors and keep the device working for a long time. Such control is carried out using special sensors installed in Xiaomi Mi Air Purifier, and mobile application in your smartphone.
Real-time monitoring and notification of the need to replace the filter.
Do-it-yourself installation within a maximum of 10 minutes.
Does not require disposal. The used filter can be thrown into the trash.
There is a fierce debate about the benefits of air purifiers. Some say that they are completely useless, and even harmful. How really?
Why is he needed at all?
The air purifier appeared in the house on the recommendation of the attending physician. According to an allergist from a local clinic, the device will reduce reactions by eliminating household allergens as much as possible. Why Xiaomi? The cost of Air Purifier 2 was comparable to inexpensive offline purifiers.
At that time, many gadgets of the Chinese brand firmly settled in the apartment, and the acquisition of another ecosystem accessory seemed logical.
Xiaomi Mi Air Purifier 2- the second modification of the cleaner, designed for deliveries to other regions. The updated device is devoid of the shortcomings of the first version. The dimensions have decreased, the efficiency has increased and, more importantly, the results of the device's operation now meet international requirements.
Now the device is designed to clean rooms up to 330 cubic meters in volume, or up to 46 square meters in area.
Functionality and operation of the cleaner. What is the point
The design is simple. There are two fans on the top for blowing out, under them there is a triple filter. The air is sucked in through the holes in the housing, is cleaned and pulled out by the impeller.
At minimum power fan volume less than the noise level outside the window(including double-glazed windows). But at the maximum, Mi Purifier makes sounds comparable to a kitchen hood, a powerful vacuum cleaner or an idle power tool.
Only two buttons are used for control. One of them, for connecting to Wi-Fi, is located on the rear panel.
The multifunctional mode change button is located next to the fans. One short press is responsible for turning on, scrolling along the rim - for changing operating modes. Three sets of presets are available: Auto, "Night" and "Custom".
In the first mode, the purifier independently determines the level of pollution using temperature, humidity and air quality sensors (according to subjective observations, quite successfully). When the second mode is activated, Mi Purifier reduces the number of revolutions (and, accordingly, the noise level) to a minimum.
"Custom" by default runs the fans on average speed. A long press of the button turns off the purifier.
There are three operating mode indicators on the front panel, and an indoor air quality indicator is located almost at the floor. If the air in the room is clean, the indicators light green. Red means heavily polluted air. Yellow - intermediate level of pollution.
The large replaceable filter combines air passes through HEPA and activated charcoal. Over time, it becomes dirty and loses its properties, so the maximum operating time is 150 days of work.
The block is inserted into slots without latches. There is only one filter element in the kit, so you should think about purchasing an additional one.
The cleaner is controlled by "smart" electronics. The control unit ensures that the filter does not stagnate.
It turns out that the resource is defined programmatic way, and therefore a working filter can be written off in the scrap. This is “planned obsolescence” in action.
On the other hand, such a surface is an ideal breeding ground for some fungi. Perhaps the manufacturer is not in vain pushing to purchase a new replacement unit in this way.
The gadget requires a connection to Wi-Fi the first time you turn it on, for which you need to press the button on the back of the device. To integrate the purifier into the Xiaomi home ecosystem, you need a smartphone and installed application mi home.
Using the application, you can configure the following parameters: fan speed in each of the operating modes; child protection (disabling hardware buttons); firmware update; automatic on/off timer; light and sound indication.
Also in MiHome you can find information about the quality of the air outside the window and view detailed performance statistics. There is data on the temperature and humidity in the room, as well as the period until the next filter change.
A lot has been written about the functioning of the unit as part of a smart home system. Unfortunately, official version required for its operation MiHome from Google Play not designed to work in Russia. Therefore, some of the functionality is left out.
MiHome is currently launching on English language and does not cause such rejection as six months ago. But problems with connecting devices persisted. And it also has not learned to determine the quality of air in our latitudes.
Air purification quality testing
Officially, the device is able to purify the air from small particles hazardous to health of categories PM0.3 (up to 99.5% of those scattered in the room will fall into filters), PM2.5 (99.7%) formaldehyde (91%), large particles hazardous to health - up to 100%.
The test was carried out using a “smoke generator” (2 people, one large hookah for two pipes, an hour of hard “labor” and tightly closed windows) in a room with an area of 12 square meters and a total volume of 30 cubic meters.
During testing of Mi Air Purifier 2, the general hood was blocked, and the Auto mode was set on the device. After that, a similar study was carried out during the operation of the common house air conditioning system.
The smoke level was calibrated using the Mi Air Purifier 2 dust sensor via the MiHome app. 500 units were taken as the initial value. When using the purifier, it took 20 minutes to reach 50 units. Half an hour later, the test came to an end with a score of 30 units, corresponding to clean air.
To reduce smoke home system ventilation took two hours. Purely for performance comparison.
Subjective efficiency
At the household level, the work of Mi Air Purifier 2 is visible to the naked eye. It suggests several use cases. Main - as permanent air purifier. Secondary - instead of a household hood. The difference in air quality in the first scenario can be seen after a few weeks.
An allergic person can breathe air from a smoky room after 10 minutes of running the air cleaner at maximum power. Or half an hour later, if the room is smoky with cigarette smoke.
Common kitchen odors, steam and smoke generated during cooking disappear in minutes.
It is possible to preserve particularly persistent odors. Particles from the filter can return to the air, be sucked back into the purifier, and so on several times in a row. Affects the absence supply ventilation in the aggregate. But for small enclosed spaces equipped with ventilation (rooms of a house or apartment), the results are very good.
Based on the data of one well-known resource in Runet, many air purifiers big brands(For example, Tefal) are inferior to Xiaomi in performance and quality.
But this is on paper. Everything is easier in life. With the advent of the purifier allergic reactions disappeared, although outside the window all summer there is a flowering field, and 100 meters from it there is a busy highway. In the bedroom there was a feeling of fresh, renewing air, it became not so stuffy. Sleep became stronger, calmer.
