Instead of an introduction. Is an air purifier necessary for life in Russia?

The need for air purifiers in Chinese cities is obvious to everyone. In the same Beijing, 21.54 million people live, several million cars drive on the streets, and coal-fired power plants and boiler houses are still used to produce energy and heating. And the phrase “go outside and get some fresh air” is not suitable for Beijing. Here, of course, it should be understood that not all 365 days of the year Beijing is shrouded in smog. And it is not always possible to visually notice that the air is dangerous. But specialized journals regularly publish materials with research on the effect of aerosol pollution on health and life expectancy. In particular, humanity is angry with particles less than 25000 microns in size, or, as they are called, PM 2.5. This is because particles of this size penetrate and remain in our lungs. They accumulate and can cause many problems and diseases, including lung cancer. In an attempt to protect themselves, the Chinese wear masks and buy air purifiers.

But this is in China. And what about Russia? In large metropolitan areas such as Moscow and St. Petersburg, the issue of clean air is quite acute. In Moscow, it is regularly recorded in certain regions that the amount of formaldehyde in the air has exceeded the permissible level. And during rush hours it is impossible to walk the streets. From the amount of exhaust gases from cars, your head starts to spin. However, of course, everything depends not only on the specific location, but also on the house, the floor where the windows open, and air flows. For example, residents of lower-floor apartments located near the roadway suffer more from dirty air than residents of high-rise buildings. Since already at the height of the 9th floor there is conditional purity and grace, where, in theory, if there is no upward air flow, the pollen of plants should not reach. Another point. If you have a pet in your apartment, a cleaner can be helpful, even if you are not allergic. This is especially desirable if you have small children. While the body is actively growing, it would be necessary for it to receive all the best, including clean air. Along the way, the purifier can help to cope with such a consequence as the smell of animals in the apartment (read the conclusion of the section about the filter!).

Accordingly, before spending money on an air purifier, you should think about the purpose for which you are purchasing it. For example, if you have no animals, a high floor and a house in the suburbs, then it is quite possible that the purifier is not needed. If you live on the lower floors of a house with windows facing the roadway, then there is a reason to think. It is best to simply call a specialist who would take proper air measurements and give a recommendation.

Appearance and device

Xiaomi Mi Air Purifier 3H looks stylish. Laconic shape, neat OLED display. There is perforation along the body.

On the back there is a laser sensor that monitors air quality, as well as a compartment for changing the filter.

Under the cover there is a cylindrical HEPA 360 ° filter.

The purifier device is simple. Air is drawn into the housing through the holes and passes through the filter. At the top of the case is a powerful reverse tilt fan.

Live it looks like this.

The entire upper part of the purifier is a grate through which a stream of air is blown out.

The blades are visible through the grate only when the appliance is turned off. When turned on, it seems that there is nothing at all

Filter

The air passes through a three-layer cylindrical HEPA 360 filter. The outside of the filter is covered with a plastic mesh and has a pull tab for easy removal. Use the tongue. The filter is relatively fragile, so if you do not drag it by the tongue, you can wrinkle it. The largest debris settles on the outside of the filter. Down, spools from clothes, threads. The wool of people and animals living in the house will also remain there. The instructions do not write about this, but I think it will not be superfluous to wipe the outer part of the filter with a damp cloth once every 10-15 days.

The second level is the HEPA filter, which, according to Xiaomi, removes 99.97% of particles up to 3 microns in size. It is this filter that is responsible for removing pollen, allergens, bacteria, cigarette smoke and even viruses.

The third level – the carbon filter adsorbs formaldehyde, odors and other harmful substances.

The filter is equipped with an RFID tag that allows you to track the service life. At maximum power, up to 6330 liters of air are driven through the filter per minute.

The filter is perhaps the main innovation of the purifier. The new filter is HEPA and the previous generation filter is EPA. EPA filters are less effective than HEPA filters. The latter retain 99.97% of small particles up to 3 microns, and EPA removes from 85% to 99.5%. But there is good news too. Owners of the second generation of the purifier can simply buy a new HEPA filter for it and upgrade the device.

The filter is a consumable item. The service life is from six months to a year, according to Xiaomi itself. But in my clean apartment, the filter still set a service life of 145 days. After the expiration date, in theory, the device will stop turning on until it is replaced. The filter price must be up to 3 rubles.

Let’s summarize a little so that there are no misunderstandings. A HEPA filter will not keep you dust-free in your home. And it will not become cleaner, although, of course, it will suck in some kind of dust. The HEPA filter removes allergens, small harmful particles of smog, pollen from the air. HEPA filters are used all over the world. For example, they are used in the nuclear industry to trap radioactive particles.

HEPA filters are not designed to remove odors. They remove particles. However, some particles in the air can have an unpleasant odor. For example, mold or particles that enter the air when smoking a cigarette. That is, removing odors is a side benefit.

Mi Home app

As with all smart appliances from Xiaomi, it is better to install the Mi Home app for the full-fledged purifier to work. In general, the application interface is laconic and fits into 2 screens. The current air quality is shown, you can select the operating mode and the intensity of air extraction from the room. You can set a timer for when the device is turned on / off. Useful information in the appendix indicates the filter life. However, even if you do not use the application, the device will monitor itself, and when the filter needs replacement, it will stop turning on.

The Mi Home app will be most useful if you have other Xiaomi smart appliances as well, as scenarios can be created. For example, if the robot vacuum cleaner starts cleaning, then turn on the cleaner to catch the dust that the robot will raise into the air. I don’t like the implementation of this particular example, since Xiaomi was too lazy to give the user freedom of action. I can only turn on the cleaner, but I cannot set the operating mode. For example, so that it immediately works at maximum power. Auto mode only. In this mode, if the cleaner sees that there is a lot of dust in the air, then it will start to work more intensively. But I would like, of course, more freedom of action.

However, the filter can also be controlled from the OLED screen. There is an auto mode, there is a custom mode, there are 3 levels of traction power. At the highest level, the operating volume is 65 dB. In automatic mode, the purifier runs silently.

Impressions of use

Unfortunately, I do not have pets, I also live on the upper floors, so when I turned on the purifier showed that my air purity level is 1 unit (the less the better), the temperature is 26 degrees, and the humidity is 50%. I don’t have an air quality meter, but the temperature and humidity matched my room electronic barometer. While changing the bed linen, he was actively shaking the sheets. The indicator rose to 0.04 units. During the operation of the vacuum cleaner, it jumped to 0.08 – 0.10. But I was so lucky. The previous generation was tested by Artem Lutfullin in 2016. As he writes, initially the indicator was 30-40 units, the device helped to reduce it to 10-15 units.

After walking around an ecologically clean apartment, I decided to give the cleaner a test and took it with me to the kitchen when I was about to fry a dirty steak. A dirty steak is when butter and then meat on a hot speed. Of course, you can get the meat wet with a napkin, but when frying, juice and water are still released from it, which, in contact with hot oil, sizzle and shoot. You start to smoke and smoke. This, of course, should not be done. The appearance of a fumes means that the temperature of the oil is too high. And it’s better not to pour oil into the pan, but just grease the steak with it. However, we have no culinary secrets here.

So, my idea was successful. The air quality index began to fall before our eyes, soon reaching a maximum value of 600 units. As I understand it, such a high figure was due to the fact that particles of hot oil, water and blood got into the air. By the way, if the steak was cooked correctly, then the air quality indicator did not rise above 100 units.

The filter took less than half an hour to return peace and grace to the kitchen at maximum power, and also almost completely remove the smell of food.


Conclusion and about competitors

Let’s summarize. Dirty air is a problem in megacities. However, everything is individual, depending on the location, the wind rose, the presence of pets, etc. Before purchasing a purifier, you should check the air quality by calling a specialist.

An air purifier will not remove dust, but it will help remove allergens, pollen, formaldehyde from furniture (read about this), etc. from the air. Better to choose a purifier with a HEPA filter. And you need to immediately decide what tasks you need a cleaner for. For example, put it in the nursery.

The filter is a consumable item. It needs to be changed. On the Internet, you can find life hacks on how to disable an RFID tag so that the cleaner works after the filter expires. But then the quality of cleaning will decrease, and why is it needed?

Xiaomi Mi Air Purifier 3H: clean air for every home!

The Xiaomi air purifier is good in its niche. It’s got impressive power, great quality, and it does its job well. There is an allergic person in the reviews on Yandex.Market, who was helped by the cleaner to cope with the pollen season, and he is happy with the device. People also write that the child was allergic to household dust and the cleaner helped.

It should be understood that in terms of its functions, this is an entry-level product. Advanced models also have a UV lamp and a photocatalytic filter. This filter helps to eliminate particles as small as 0.001 microns. I have a similar cleaner in St. Petersburg. A good power model cost more than 20 thousand rubles. Along the way, it has the function of air ionization.

Before buying a purifier, you should understand for what purposes and tasks it is being purchased. It is worth measuring the current air quality and then acting.
