It’s unlikely that anyone will argue that living in a clean apartment is better than living in a mess. And it’s not just about the aesthetic perception of the surrounding space. Dust and dirt can cause various diseases, allergic reactions and simply discomfort. How to properly clean up own apartment, we have already found out. Today there is another issue on the agenda - cleaning the air in the apartment.
Those in power are increasingly thinking about the environmental situation in cities. And the scientific brethren have been sounding the alarm for a long time. The country is full of cities choking on industrial emissions. Household waste landfills surround megacities in a continuous ring. It is not uncommon for people to move to another area due to unpleasant odors and dirty air. And there is no improvement yet.
The only solution left is to take care of yourself. Relocation is not always possible. And where is the guarantee that the same thing will not happen in another area over time? Let's try to figure out how to determine air pollution? What devices will help make the air in your apartment cleaner? Well, at the same time, we’ll tell you who to write a complaint about the pollution of the atmosphere around us.
Air purification in the apartment. A little theory
The composition of the atmosphere is familiar to everyone from school. The basis is nitrogen and oxygen. Only one percent comes from all other gases and other impurities. Every year the amount of suspended matter and unusual substances increases. Power plants, cars, metallurgical and chemical plants constantly emit hydrogen sulfide, carbon dioxide, sulfates, ammonia and other harmful substances into the air.
The easiest way to determine the cleanliness of the air is with your nose. And it's never funny. If there are landfills, smoky enterprises or large highways close to your home, you can feel the smell. Even weak. And you don’t need to pay for an eco-tester :) Naturally, not everything is so simple - it’s not enough to feel the “aroma”, you need to know what it is. It’s easy to find the information you need on the Internet. For example, the smell of rotten eggs means a high concentration of hydrogen sulfide.
INTERESTING. Scientists believe that the main consequences of pollution of the earth's atmosphere are smog, acid rain, destruction of the ozone layer and the greenhouse effect. If two latest problems are not noticeable to the average resident, then smog and acid rain are frequent phenomena in many large cities. The greatest problems are observed in industrial centers and places where industry is concentrated.
If it smells like sewage, then mercaptan derivatives have accumulated in the air. Difficulty breathing, a distinct chemical smell and taste, a feeling of burning or dust indicate a high content of harmful substances. You need to act immediately. You shouldn’t wait for everything to pass, of course. You need to buy a device to purify the air in your apartment.
If you are “lucky enough” to live in a large industrial center, air pollution can not only be smelled, but also seen. This could be a colored cloud, clouds of dust, or a darkening of the atmosphere. All hope lies in special services involved in air quality monitoring. For example, in Krasnoyarsk this is Krasnoyarsk.nebo or Smoky74.ru in Chelyabinsk. Definitely useful services.
But it is better to buy special analyzers. There is no need to bother with expensive instruments that can show fractions of a percent of a huge amount of substances. A compact integrated analyzer is sufficient. Such a device will show the overall degree of pollution, but will not tell which substances threaten health. But this is not necessary; a signal of danger is enough to take action.
There is nothing complicated in the operation of the device - the color of the indicator will indicate the degree of danger. According to international standards, red means danger, yellow warns of high levels of pollution, and green indicates normal air purity. But the main thing is different: a household analyzer costs several times less than a professional one. You can buy a natural gas analyzer, but this is a little different. Although it will protect against leaks.
Air purification in the apartment. What are the dangers of pollution?
It has long been no secret to doctors what diseases are caused by polluted air. At a minimum, respiratory problems. Frequent colds, allergic reactions, decreased immunity - this is an incomplete list possible problems. In the worst case scenario, a person faces cancer. For example, when in the air long years the concentration of formaldehyde is exceeded.
What can be done? How to protect yourself and loved ones from harmful consequences? Unfortunately, there is no simple and universal solution. After all, we won’t really be walking the streets in a gas mask or respirator :) We definitely need to install a purifier in the apartment. But moving around the city is more difficult. We close the airways with a scarf and quickly leave dangerous place. If you feel worse, call an ambulance!
Which air purifier to choose . Main types
Technologies make it possible to purify the air of any type of pollution. There is no shortage of household versions of cleaners on the market. This device is designed to work in a room of a certain area. Hence the conclusion - than bigger apartment, the more powerful the cleaner needed. Accordingly, the cost increases depending on the class of the device. And if you decide on a complex gadget with ionization or humidification, get ready to shell out a tidy sum.
Cleaners are divided into several types based on their operating principle. Let's say right away that there are no universal solutions. Some devices are good at cleaning dust and particles. Others remove inorganic compounds. Still others retain organic matter. Much depends on the filter used. Now let's look at the main types of air purification devices and analyze the advantages and disadvantages.
Air purification from dust in the apartment - electrostatic filters
Purifiers with a “plasma” filter create an electrostatic field in the air flow path, due to which suspended particles collect on the surface of the filter. The efficiency of the devices reaches 90 percent. The second advantage is ease of use. Plates made of special alloys are used as a filter, which are easy to clean from contaminants.
But there is also negative points. The cleaner operates based on a certain amount of dust. If the concentration of suspended matter is higher than normal, then the filters cannot cope. As a result, the device either becomes clogged or begins to leak dust. So when purchasing, carefully study the performance characteristics. For rooms where asthmatics or allergy sufferers live, we recommend choosing devices with several degrees of cleaning.
Which air purifier to choose - ionizers
We are looking at a completely different type of air purifier. In fact, it is a complex consisting of several elements. Each part is responsible for its own cleaning method. This means that ionizers are more versatile than plasma filters. The first stage of cleaning is the capture of large particles using foam filters. Then the photocatalytic filter comes into play - complex chemical compounds are destroyed.
IMPORTANT! The main air pollutants are: carbon dioxide, carbon monoxide, nitrogen oxides II and IV, sulfur dioxide, heavy metal compounds, complex organic compounds. Ozone is considered a hazardous substance. Despite performing an important function - protecting the planet from cosmic radiation - the substance is harmful to living organisms in large quantities.
The air then enters under the germicidal lamp and passes through the plasma filter. The last stage purification is the adsorption of negatively charged ions. The multi-stage design has undeniable advantages - the filters are cleaned separately. The system does not require replacement; it is enough to periodically wash the plates and vacuum the foam filter.
How to choose an air purifier for your home - HEPA filter
The operation of such devices is based on the passage of air through a special fibrous material, folded in a certain way like an accordion. The structure of the filter is such that the purifiers are able to effectively retain even plant pollen. So the device is ideal for people suffering from allergies. The second advantage is simple operation. It is enough to clean the container with the filter element once or twice a year.
How to choose an air purifier - photocatalysts
Interesting devices that can retain suspended particles and neutralize chemical pollution. The arrangement of the filter elements allows you to trap solid particles, spores, dust mites and animal hair. The main part is an ultraviolet lamp and a special catalyst. Photocatalytic purifiers can be equipped with plasma or carbon filters.
The main feature is a chamber with a catalyst. Here, complex compounds are decomposed into safe components: water, carbon dioxide and oxygen. This avoids the formation of sediment, meaning this element will not require frequent replacement. Photocatalysts easily cope with exhaust gases, phenol, formaldehyde, soot, tobacco smoke, household chemicals and substances of natural origin.
Which air purifier to choose for an apartment - ozonizers
The operation of such devices is based on the strong oxidizing abilities of ozone. A small amount of gas can decompose almost any compound, both natural and artificial. Ozone is created directly when the purifier is operating using a strong electrical discharge. Everyone knows the fresh smell after a thunderstorm. This is exactly the process that occurs in the ozonator.
There are more than enough positive aspects - the destruction of microorganisms, spores and viruses, the decomposition of complex compounds. In addition, the device is able to disinfect furniture, clothing, food, and eliminates unpleasant odors. But there is also a minus - in large quantities, ozone is harmful to the body. We advise you to use the ozonizer strictly according to the instructions or turn it on when none of the residents is at home.
Cleaning the air from dust in the apartment - carbon filters
This technology is widely used not only for air purification. Think of activated carbon tablets or water purification filters. The carbon filler is a fine filter and cannot work independently. How additional elements, HEPA filters or photocatalysts are used. No other way. The coal component is not able to stop biological pollution.
When choosing a device, we advise you to pay attention to the composition and structure of the filter plate. The best option would be a corrugated design with medium-sized granules. This will reduce air flow resistance and increase filtration quality. Most models do not require constant monitoring. Carbon elements need to be changed every 6-8 months. One more thing - do not use such cleaners in bathrooms or bathrooms.
Water air purifier
Not long ago, the terms “hydrofiltration” and “air washing” came into use. The principle of operation has been known for a long time, but its implementation in household appliances happened relatively recently. These purifiers mix air with water until a homogeneous mixture is formed. As a result, the impurities settle, and the separated air comes out. Often, “air washers” are equipped with an ultraviolet lamp and a photocatalyst.
FACT. According to WHO, every eighth person who died during the year was affected by air pollution. At the end of 2015, this is approximately 7.5 million. Studies have revealed a direct relationship between air purity and diseases of the heart, blood vessels, respiratory tract and cancer.
The integrated approach effectively removes particulates, neutralizes chemicals and neutralizes biological activity. Such cleaners are considered the most productive. The cleaning effect is about 95 percent. Add air humidification and you get excellent protection for your home atmosphere.
Air purification and humidification in the apartment
Humidifiers purify the air to a lesser extent. The main function of the device is to create an atmosphere with a given humidity. This is achieved by injecting purified steam. Devices are divided into three classes: mechanical, ultrasonic and steam. Most models, in addition to humidification and partial cleaning, are capable of aromatizing the air. We recommend choosing humidifiers that use ultrasound.
Mechanical devices make a lot of noise. Steam generators that operate by heating water consume quite a bit of electricity. And the steam is hot :) unlike other types of humidifiers. In terms of maintenance, “ultrasound” is also preferable. Scale does not form in the system, like with steam generators. There is no need to change cartridges, as in mechanical humidifiers. It is believed that the latter last a long time. But it all depends on the composition of the air.
Air Purifier Rating
Compare cleaning systems operating on different principles, a bit complicated. Although recently manufacturers have been trying to produce universal cleaners that combine the advantages different ways cleaning. By the way, there is an indicator of the efficiency of such devices - GOST R EN 1822-1-2010.
If you look at sales of cleaning equipment, several brands are clearly in the lead: Boneco, AOS, Ballu and Venta. The average price for the products of these manufacturers is approximately 15-17 thousand rubles. Not weak, but for so many “pieces of paper” we buy a universal air purifier with a bunch of additional options and a minimum of noise.
Models from Sharp, Aic and Daikin are cheaper due to their focus on the main function. The number of “left” options is minimal, humidification is also secondary. Nevertheless, the devices do an excellent job - the indoor air meets environmental standards. All that remains is to look at the “best of the best” :) So, the best air purifiers.
- LG Puri Care AS60GDPV0. Without exaggeration, the device can be called a modern technological gadget. What are air purity sensors worth? One controls the presence of dust, the other controls odors and gases. Signals from the sensors go to the processor, which selects the operating mode. We can say that the purifier constantly monitors the situation and selects the optimal mode. The only and not frail minus is the price. This miracle of South Korean technology will cost almost 60 thousand.
- Boneco H680. Interesting solution allows you to separate air purification and humidification. As they say, whoever likes what :) The hybrid filter can easily cope with ordinary dust, pollen, spores and unpleasant odors. About a liter of water per hour is consumed for humidification. If you look at the filling, then we actually have a climate control system - the system monitors the air condition and selects the desired mode.
- Dyson Pure Hot + Cool. A kind of combination of a fan, purifier and heater. But it copes with air purification with a bang. By the way, the model has been certified for use by patients suffering from allergies and asthma. Heating may be needed in cold summers, but this is not a fact.
- Xiaomi Mi Air Purifier 2. A unique device of its kind. It seems to be sold here, but at the same time it doesn’t seem to be :) According to official data, the company does not supply this model to the Russian market, but you can buy it without any problems. The characteristics are impressive - in 10-15 minutes the air in a room of 20 square meters is completely purified. A combined filter capable of removing dirt, odors, organic matter and chemicals. I was pleased with the price - only 8.5-9 thousand.
- IQAir HealthPro 250. The Swiss pay a lot of attention to design in their repertoire. But it’s also a sin to complain about the work of a cleaner. Triple purification is able to filter out any impurities, be it gases, spores, pollen or regular dust. According to independent tests, it is 99.97 percent effective.
What is an air purifier
The technical component has been discussed, so we will not return to this issue. If we look at the problem of clean air from the point of view of an ordinary city resident, then a cleaner, albeit expensive, but a necessary gadget in our apartments and houses. In areas where the situation is favorable, you don’t have to install it. But exhaust fumes and dust will not go away.
Finally little advice. If you experience unpleasant odors for a long time, call Rosprirodnadzor. It is this office that is responsible for the environmental situation in the country. You can contact the regional Departments of Environmental Management or the Ministry of Emergency Situations. The last option is relevant for smoke and odor that is clearly of chemical origin.
Any adult and educated person knows that the air in the city is not only far from natural purity, but is also sometimes dangerous to health. And in order to protect against it, at least at home, we use special equipment. How not to get lost in the variety of gadgets and choose the best air purifier? Let's look at everything in order.
Fresh air in the home can be classified as basic physiological needs. And if you don't live in a clean suburb or at least near a park, then most likely you need an air purifier. Modern manufacturers they create and modify such devices in huge numbers, adding the necessary (or not?) functions of ultrasound, ionization, humidification, and so on, ad infinitum, changing the shapes, sizes and number of filters, thus completely confusing the buyer. Let's figure out what air purifiers exist now and what they are needed for.
There are no fewer myths in the field of air purification now than in show business :) But for the most part, all air purifiers consist of a fan, which drives this very air through the gadget, and a filter system. And it is in the latter that all the differences begin. To begin with, let’s divide all cleaning systems into two types:
- aquatic;
- dry.
They most often try to combine an air purifier for an apartment with a humidifier, which has already created some confusion between these devices. However, a conventional humidifier does not purify the air, but only fills it with moisture, and of such devices, only an air washer can bear the proud title of “air purifier”. This type of home air purifier actually “washes” the air by forcing it through a curtain of water. At the same time, under the influence of water, dust and other small pollutants in the air settle on the washing discs. Air purification using washing occurs along with humidification, which adds to the popularity of these gadgets. All air washers work on the same principle and differ in size, fan power and availability. additional functions. Air disinfection is most often introduced into the sink. In addition to the desire to introduce as many functions as possible that are attractive to the buyer, in this case, manufacturers are also guided by the principle of compensation - the fact is that the humid environment formed in sinks is very favorable for the growth of bacteria, harmful microorganisms and fungi; the sink must be constantly looked after and cleaned it so that unexpected guests do not settle in the device.
Therefore, such an air purification system is often supplemented with a UV lamp for safety. We have already discussed how safe this technology is in another article.
In addition, the sinks themselves work quite sedately and calmly; you should not expect them to quickly clean the room, remove odors and the smallest particles of pollutants and allergens.
| Model | Description | pros | Minuses | Price |
| Venta LW25 | Designed for a room up to 40 square meters. meters. The sink operates without replaceable filters, the entire cleaning system is washable. For work, you can use ordinary water, the reservoir for which is 7 liters, as well as flavored additives. Protection against bacteria is provided by the Venta-Hygienemittel system. | No consumables required. Doesn't leave limescale on furniture. Easy to care for. Auto shut off without water. Possibility of connecting a humidity level sensor. |
High noise level at maximum speed. | From 23,000 R |
| Winia AWI-40 | The Korean car wash can also serve up to 40 square meters and has a 7 liter tank. Its features include the function automatic maintenance humidity levels, five operating modes, 3D discs with antibacterial coating. The sink also has an ionization function, implemented through replaceable ionizing filters. | Easy to care for. Humidity level control. Antibacterial coating of discs. High humidification efficiency. |
Replaceable ionizing filters. High noise level. Inaccurate gyrostat. Difficult to find in stores. |
From 15,000 R |
| Boneco W2055DR | A simple air cleaner designed for a room up to 50 square meters. meters and 7 liters of water. It is possible to monitor the current humidity level and set the desired one. You can use flavorings, there is an ionizing rod, which can also function as protection against bacteria, which, in our opinion, is very doubtful. | Two operating speeds. Electronic hygrometer. Automatic maintenance of humidity level. Indication of the level of contamination of the device. |
Weak antibacterial protection. Large dimensions. Quite labor-intensive cleaning of the sink. |
From 25,000 R |
If we talk about cleaning the air from dust, allergens and odors without the participation of water, then the choice of gadgets becomes many times larger. The devices differ in size, performance, design, and most importantly, what air purification filters are inside and how many there are. But for the most part, all devices of this type have high power and can quickly purify the air in the room. Dry cleaning systems include a more powerful fan that forcefully draws air from the room and forces it through the filtration system. The main types of filters found in such systems are:
- Coarse air filter. Typically a mesh or porous material that can trap large contaminants, such as dust bunnies or animal hair.
- Fine filters. They usually look like a fabric or paper material folded like an accordion. The filter material has many pores, which, due to an unusual bend, overlap each other, forming a fine-mesh non-linear sieve. Such filters trap dust particles and most allergens.
- HEPA filters. Today, such filters are the most effective for air purification. They trap even the smallest and most dangerous pollutant particles, such as PM2.5, tiny allergens such as dust mite secretions, and so on. Taking all this into account, a HEPA filter for air in an apartment is necessary; without it, the entire cleaning system will be incomplete. We have already described the technology of their operation in detail in this article.
- AK filter, also known as adsorption-catalytic filter. If, in addition to dust, allergens and harmful particles, you want to protect yourself from unpleasant odors, then the air purification system in your apartment must include such a filter. Inside the filter there is a special material that literally “draws” gas molecules into itself and securely locks them inside. Some manufacturers make variations of the AK filter, for example, standard and enhanced, if the sources of unpleasant odor are very strong or are too close to the room. Carbon and photocatalytic filters perform the same functions.
The best air purifier for an apartment, of course, will contain both filters to clean the air from dust and protection from allergens, harmful particles and unpleasant odors. Most often, the disadvantages of such devices include energy consumption and noise levels. In fact, a high-quality air purifier consumes no more energy than other household appliances (and often several times less), and the noise created by the gadget is of an aerodynamic nature, caused by the passage of air through the filter system. However, with the help of new technologies and materials, some models have gotten rid of this noise and now work so quietly that sometimes questions arise as to whether the device is turned on at all :)
Who cares: additional functions in air purifiers
When choosing which air purifier is best for your home, people usually pay attention not only to the number of filters, but also to additional features. Let's look at the most popular of them.
| Function | Purpose | Principle of operation |
| Ionization | Saturation of the air with useful, according to the manufacturer, negatively and positively charged ions. | Ionization is a rather debated process, and there is currently no single authoritative opinion on it. Some say that ions are practically a panacea, others call them dangerous for humans. We examined this process in detail in another, and taking into account all the features and possible side effects, for ionization it is best to use a separate gadget with an adjustable operating time. |
| Aromatization | Filling the air with pleasant aromas through the use of aromatic liquids. | Aromatization works on the principle of an air freshener, spraying a concentrated fragrance in liquid or gaseous form into the room. How rational it is to add aromatization to an air purifier is an open question, since a filter for air purification in an apartment often includes odor removal, which means the air purifier itself will eliminate the work of the aromatizer. |
| Hydration | Saturation of air with water vapor. | Humidification is one of the most popular additional features in air purifiers. On the one hand, air humidity is very important for normal operation. human body, and it is necessary to maintain it at normal levels, on the other hand, creating a humid environment near the filters of the purifier is short-sighted, since this is where all the harmful microorganisms gather, which, if a suitable environment is created, can begin to actively multiply and actually turn the purifier into a source of infection. |
Air disinfection is most often confused with air purification. It represents the destruction of pathogenic bacteria, viruses and other microorganisms and, perhaps, this function is worth dwelling on separately. Air disinfection is most relevant in the medical field, but it can also be very useful in everyday life. Even the best quality home air filter can capture harmful microorganisms, but does not destroy them. In modern air purifiers, two methods of air disinfection are most often used:
- Photocatalytic filter with UV lamp. Photocatalysis and UV radiation have been used together for quite a long time, allowing them to solve two problems at once - unpleasant odors and the destruction of microorganisms. Unfortunately, the age of this technology has also become its main problem - now many viruses and bacteria are already resistant to UV radiation, and such irradiation itself is not always safe for humans. We have already examined UV lamps and their scope of application in detail in another; now there is no point in retelling the entire history of this issue. If you are using an air purifier with a UV lamp, strictly follow the instructions for use.
- Inactivation of microorganisms. Modern technology that deprives all pathogens of the ability to reproduce, inactivating them with ozone produced inside the device. Thus, the purifier and air disinfectant complement each other: HEPA filters trap pests, and the disinfection system immediately inactivates them, leaving the air purifier itself sterile. At the same time, filters are provided to decompose the ozone created in the device, so that additional ozonation does not occur in the room. Now inactivation is implemented only in a few models, for example in Tion air, but we believe that the future lies with this technology and will soon be used to protect their health in every home.
Also, if we talk about multifunctional gadgets with air purification, we cannot fail to mention. These devices provide a constant flow fresh air with the windows closed, cleaning it using three levels of filtration - protection from large dust, thorough cleaning from the smallest harmful particles and allergens with a HEPA filter of at least H11 class, retention of molecules of harmful gases and unpleasant odors. In addition, the breather heats the air to the selected temperature and automatically maintains it. The most advanced models are connected to the MagicAir smart microclimate system and automatically regulate the supply of fresh air in the house. In addition, there are models with a recirculation mode, in which the air that is already in the room is quietly purified and heated, that is, one device immediately performs the functions
Air from a restaurant or cafe hood escaping into a residential area can cause complaints from neighbors and fines from inspection authorities. If the air duct cannot be installed above the roof ridge or on the facade, then the only way to avoid claims is to achieve effective cleaning exhaust air from odors, smoke, soot, burning and grease.
For this purpose, the restaurant kitchen ventilation is equipped with a Tion comprehensive air purification system. It is located immediately after the spark arrester and grease trap and removes smoke and odors from hot shops, barbecues, grills and other sources. This makes it possible to equate the air from the restaurant kitchen hood to household emissions and remove it at the level of the first floor, without causing inconvenience to people living or working in the neighborhood (in accordance with SanPiN 2.3.6.1079-01, clause 4.6).
- To clean the exhaust air of all types of stoves (except wood-burning and barbecues), Tion Ext duct air purifiers are used (capacity from 400 to 27,500 m3/h).
- For cleaning exhaust air wood stoves and barbecues, Tion Ext Advanced duct air purifiers are designed (capacity from 2000 to 6000 m3/h).
- For rooms where the concentrations of removed contaminants are very high, an additional Tion Ext-El restaurant air purification unit from gases and odors is installed.
Air purification from smoke and odors in a restaurant hall
Restaurants, cafes, canteens and other establishments Catering often face the problem of food and smoke odors that can be felt in the hall. To improve the quality of service and customer loyalty, it is necessary to properly organize smoke removal and ventilation in the dining area of the restaurant.
The Tion Ext restaurant air purification unit solves the problem of removing smoke and odors effectively and profitably. Thanks to a unique multi-stage cleaning system with smoke filters, the Tion Ext duct air purifier eliminates all types of contaminants.
Tion Ext air purification equipment is placed in the restaurant ventilation system in two ways. It can be installed both in the supply branch and in the recirculation branch after the supply chamber.
Compact air purifiers for restaurant halls
Air purification from odors and smoke in a restaurant can be done using compact autonomous air purifiers Tion Clever.
This perfect solution for those cases when the restaurant ventilation system does not provide for the possibility of integrating odor and smoke traps into it.
And if smoke filters are already installed in the ventilation of a cafe or restaurant, then compact air purifiers will enhance their effectiveness and increase the air exchange rate. This will create a comfortable environment and attract visitors.
I purchased this air purifier in 2014 for 7 thousand rubles. There was a need for an air purifier in the apartment, since pieces of furniture and old parquet began to give bad smell. Based on reviews on the Internet, we chose this model - AIC 20B06.
The purifier works as follows: it has holes on the sides for air intake, the purified air comes out from above the device itself, very thoughtfully, since the device provides high air circulation in the room. In general, all the holes are made correctly, thereby processing a large volume of air.
As for whether the air purifier copes with its task, otherwise the device may be working and it is not even known whether the air is becoming cleaner; it is not visible to the eye. But it really cleans the air of odors and dust! Since I have some problems with odor in my apartment, which also causes a sore throat, this cleaner solved this problem. When it is turned on, there is no smell, but when you turn off the device at night, the smell accumulates and is felt again in the morning (ventilating the rooms does not help with this).
Also clear example excellent work AIC 20B06. Once there was a fire in one of the apartments at our entrance; the smell of burning naturally penetrated through the cracks in the door; the entire corridor was shrouded in clouds of smoke. The air purifier was immediately turned on. And while it was working for several days, there was no smell of burning in the apartment at all, but as soon as the device was turned off, after 30-40 minutes the smell appeared again, and in the entrance the smell of burning persisted for about another month. This is how we were convinced of the effectiveness of the air purifier.
Externally, the air purifier is nice and fits into any room interior. The size is small. The kit includes a remote control that operates over a long distance. The air purifier does not operate very noisily, a night mode is provided, but this in fact means that the display itself becomes dimmer and that’s all, the noise of the device in this case does not change, it is exactly the same as the operation of the device on minimum speed(3 speeds in total). The purifier also has an ionization function and a UV lamp; they can be turned on/off with just one button; the effectiveness of this function has not yet been tested.
