xiaomi mi air purifier 2 filters specifications

26.10.2019

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 transmit information about the environment, and the main function of Mi Air is controlled by one 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 the Russian post 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.

Application

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 distributes Xiaomi Mi Air Purifier 2 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.

conclusions

There are absolutely no complaints about the appearance. 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. Knowing the basics is enough to understand interfaces of English language, and the rest 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

You choose the water you drink, but do you choose the air you breathe? The air you breathe depends entirely on the environment you live in. So, if your city is polluted, then the air in the house is not very good. good quality. What do you do in such a case? Using an air purifier is your only option.

There are many air purifiers on the market, but when you see the price of them, the desire to buy disappears. In the midst of the crisis, Xiaomi brought its successful air purifier to Russia - Mi Air Purifier 2. The device is quite cheap but performs on par with most top brands which are 2-3-4 times more expensive. How is this possible? Don't forget, this is Xiaomi.

The Mi Air Purifier is one of the first products in the Xiaomi smart home appliance family. The device is a second generation version and has a significant improvement over the older variant.

Hello, friends

opening speech

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 -

Additional Information

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.

Purchase

After waiting for the next flash sale, which took place in early April, I bought the hero of the review for $150, in total, together with delivery, he cost me $156.53

By the way, on the Russian version of the store - add ru. before gearbest - usually much cheaper, works with many products.

Additional Information

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 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.

Purifier device

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.

Appearance of the control plugin

Depending on the mode of operation - either the status is turned off or the amount of PM 2.5 is displayed, in sleep mode - the background turns blue.

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.

Favorite mode - allows you to manually set the intensity of air purification, depending on the area of the room. Adjustable from a minimum of 1-4 and a maximum of 34-37 square meters.

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 the Opel translation plugins (from 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 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.

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. original model, Xiaomi Mi Air Purifier, turned out to be too large for use at home, and after a while the Chinese released Mi Air Purifier 2, it became about one and a half times more compact with comparable performance. But back to the basics of this idea.

Air purifiers are a separate class of household appliances related 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. This is actually very discomfort, and the fact that the air is dirty and heavy, you feel literally immediately, being 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.

Here it should be noted that appearance The Chinese did not develop 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 folded HEPA filter that traps suspended particles, and an internal one with activated carbon filler), 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 readings from 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. The "Sleep" mode is designed to run the purifier at night or when you need it to be quiet - low performance pays off with the almost complete absence of 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. No other positive effects From the operation of the device, I, unfortunately, did not notice. 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 that is given description inspired 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.

Xiaomi Mi Air Purifier 2 is an efficient and reliable air purifier that can remove fine dust, formaldehyde and various odors. Its installation at home or in the office allows you to saturate the room with fresh and clean air, in which there will be no microorganisms and bacteria dangerous to humans.

The advantage of the device is an intelligent system that independently monitors the state environment and, depending on the results obtained, chooses best option work. In order to achieve maximum efficiency from the device, it is necessary to properly configure it. Read our article on how to do this.

Connection instructions

The Xiaomi Mi Air Purifier 2 is equipped with a Wi-Fi module and is designed to be used as part of the Xiaomi smart-home system, so the Mi Home proprietary application is used to control it. It is available for free download in the Google Play Market and can be installed on any device with Internet access. Most users prefer to install on a smartphone, as this allows you to organize remote control all components included in the "smart home".
