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.

Precleaning, which does not allow the penetration of large volatile particles into the device. The type of operation of which is based on modern nanotechnologies.

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. 360˚ circular retraction ensures high performance, while three stages of filtration ensure perfectly clean air exiting 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.

Adsorbs unpleasant odors from the 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 a 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.

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 unpacking

The 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 from which you can get information about the overall dimensions - 29 * 29 * 58 cm, maximum power consumption 31 watts, weight 6.2 kg, operating voltage 100 - 240 V.

This cardboard box, unlike for example from 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 covers, in Chinese, but in clear pictures, the replacement process is shown air filter, and cleaning the dust sensor

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 was used up, worked for 149.2 hours, which is equivalent to being in some Chinese forest for 6.2 days, and cleared 5585 cubic meters 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.

Video version of the review:

I hope the review was interesting - thank you for your attention.

In fact, Xiaomi has already released two versions of the air purifier. The original model, Xiaomi Mi Air Purifier, turned out to be too large for use at home, and after some time the Chinese released Mi Air Purifier 2, it became about one and a half times smaller with comparable performance. But back to the basics of this idea.

Air purifiers - a separate class household appliances referring to "beauty and health" or something similar. There are humidifiers, air washers, ionizers, purifiers and other things. In the case of Xiaomi Mi Air Purifier, we are talking about an air purifier designed to remove mainly harmful PM2.5 particles - fine dust. The fact is that, according to various data and studies, fine dust is the cause of many diseases, including cancer. So, for example, in 2013, the International Agency for Research on Cancer (IARC) published the results of studies that noted that particulate matter and air pollution increase the risk of lung cancer, and, according to IARC data for 2010, cause more than 200 thousand cases of lung cancer was precisely air pollution. In China, the issue of air pollution is particularly acute. Major cities like Beijing and Shanghai are sometimes covered in smog for months at a time. Arriving there, you seem to find yourself on the ground from the movie "The Matrix", where the sky is covered with clouds and the sunlight simply does not break through them. These are, in fact, very unpleasant sensations, and the fact that the air is dirty and heavy, you feel literally immediately, once in such a city. What then to say about the people who live in such cities all the time?

Design, materials, dimensions

Xiaomi Mi Air Purifier looks great - a stylish, neat "box" made of white plastic, which will fit perfectly into literally any interior.

It should be noted here that the Chinese did not develop the appearance of the air purifier on their own, but, as in any other field, they simply borrowed it. The inspiration (stroke) was the Japanese air purifier AirEngine from Balmuda.

One way or another, it turned out great, and you can’t blame the device for the lack of beauty and grace, despite the fact that this is an ordinary white plastic box.

The size of the new Mi Air Purifier has become noticeably more compact than the first model, which is good.

Design, principle of operation

The upper panel of the purifier is a grille for the outlet of purified air. Below it are two fans.

On the side faces there are holes for air intake, they are located on three sides.

On the reverse (rear) side of the purifier housing there is a removable cover for installing and subsequently changing the filter. On the inside of the cover there is an instruction explaining the principle of installing and changing filters.

Unlike the original Mi Air Purifier, where there were two filters (an external one with a coarse mesh and a pleated HEPA filter that traps suspended particles, and an internal one filled with activated carbon), only one was left in the Mi Air Purifier 2, an external filter.

The principle of operation is as simple as possible - the purifier sucks in air from the surrounding space, drives it through the filter, cleaning it from harmful particles (mainly PM2.5) and removes it through the upper area.

The declared performance of the purifier is up to 310 cubic meters of air per hour when the corresponding mode is turned on.

Important point, the plug of the bundled cable is somewhat different from what we are used to seeing, including in Chinese devices, so if you order a cleaner, you should take care of finding an adapter or use some of your own instead of the bundled cable, from the power supply, for example.

Purifier application, indicators

In general, the air purifier has one button on the body, and it is enough to turn it on and select the desired operating mode. There are three of them - "Auto", "Sleep", "Selected profile".

In the first, the purifier works at the level of performance that is necessary to clean the room in a calm (silent) mode, based on the readings of internal sensors. Sensors measure the level of ambient air pollution and display this information on the indicator on the front panel of the purifier. If it burns green - the air is clean, red - polluted. Sleep mode is designed to run the purifier at night or when you need it to be quiet - low performance pays off almost total absence fan noise. Finally, the third mode - it needs to be configured through the application. Choose the area that you want to clean as quickly as possible, and by turning on this mode, switch the cleaner to maximum performance. At the same time, it will make a lot of noise, not like a vacuum cleaner, of course, but still.

All additional information from the purifier, as well as the most important - the current level of air pollution, can be viewed through the Mi Home application. Communication with the purifier is configured through a router (shared home Wi-Fi), and in the future, the purifier's operating modes can be controlled from anywhere, even if you are not at home.

The app displays useful data and various settings. Here you can also set timers for the cleaner, select the brightness of the LED, enable or disable sound alerts, and other settings.

Conclusion

The purifier does its job well, and my PM2.5 pollution level is now very low, the average now is 10-15 units, while before installing the Mi Air Purifier, the figure was at the level of 30-40 units. Unfortunately, I did not notice any other positive effects from the operation of the device. On the Xiaomi website, in the description of Mi Air, it is indicated that it purifies the air not only from PM2.5, but also from dust and other large particles (including hair), and it was this description that prompted me to install it. I naively thought that by installing such a thing in the room, I could get rid of dust, or at least I would less often clean the room (now I do it every 2-3 days). As a result, after two months of operation of the cleaner, I can say for sure that it does not help with any visible dust. As I collected a layer of dust on the table in two or three days, it is collected, as I carried out the cleaning of this very dust every two or three days, and I spend it.

At the same time, I absolutely do not want to say that Xiaomi Mi Air Purifier 2 is a bad device. Firstly, its main task is still to remove harmful particles of a different kind, PM2.5, and with this, according to the readings of the device and the application, Mi Air copes more than well. Secondly, it is obvious that “my expectations are my problem”, and it was foolish to wait for the complete removal of ordinary household dust. True, I want to note that there are still other effective devices for dust control. For example, not so long ago I used an air washer from LG, LG Mini On for several months, and there was a noticeable effect on dust: during this time I noticed, even visually, that there was less dust in the room, and cleaning could be carried out once a week, that is, twice as often. I will talk about this device in a separate article.

In China, Xiaomi Mi Air Purifier 2 costs 1,000 yuan, but you can’t buy it (right now) in an online store, you need to look for a device in partner stores. On sites like GearBest.com and others, the device costs an average of 160-180 US dollars, that is, about 10,000-12,000 rubles. At the same time, Panasonic air purifiers are twice or even three times more expensive. Yes, as a rule, these are devices of a different class and there are combined systems for cleaning, humidifying and ionizing the air, but still. If you need some simple device to clean the air from harmful particles, you should pay attention to Xiaomi Mi Air Purifier 2.
