We always want to find the best for ourselves. If you really invest money, then not to regret about it later. This is especially important when choosing health products. How to choose the best one? After all, it is not easy to feel the result of his work. For example, it is very easy to evaluate the operation of a vacuum cleaner, and how well the air cleaner coped with pollution is only partly clear, because the human eye cannot see the most dangerous pollution.

What qualities should the best air purifier have?

Undoubtedly, the more types of contaminants the device can eliminate, the better it is, but at the same time, low noise level, low power consumption, low costs for replaceable filters, convenient operation, reliability and safety, and pleasant appearance are also important.

1. For many of us, when choosing a purifier, the main problem that needs to be solved is dust. So the best air purifier should remove dust from the air as efficiently as possible. Air cleaners with HEPA filters handle dust best of all. In addition, the device must quickly push air through the filter, otherwise it will only clean a small part of the room.

Conclusion 1: The best purifier should have a large area HEPA filter and a high air velocity for quick dust removal.

Those. it is better to choose a device that will be designed for a room larger than where you are going to put it. Also pay attention to the air exchange rate of the selected device, it should be 1.5-2 times the volume of your room, so that all the air can be cleaned in an hour.

2. Decoration materials and furniture in modern homes and offices emit a host of harmful chemicals that can damage human health. Often there are various smells from cooking, smoking, neighbors, pets, household chemicals. In a closed room, germs, bacteria, mold, dust mites, which cause allergies and various diseases, multiply very quickly. Photocatalysis is the best solution to the problem of odors, microbes, and volatile chemicals.

Conclusion 2: A good air purifier must have a photocatalytic filter to remove odors, germs, chemicals.

If the problem of dust is not relevant to you, it is important to get rid of only odors; you are not ready to bear the costs of purchasing replacement HEPA filters. In this case, an electrostatic air cleaner is optimal. need to be decided in advance. Dust bothers - choose a Nera filter, odors, tobacco smoke bothers, and the dust is not particularly electrostatic.

3. In a closed room, the air becomes "dead", because closed by walls and a roof, it cannot be electrically charged by the sun, earth, or lightning. In such a space, a person becomes lethargic, often begins to get sick. To prevent this from happening, choose.

Conclusion 3: The best purifier must necessarily be ionized to refresh and restore the natural qualities of the air necessary for human well-being.

4. The best device will be the one that has several modes of operation: powerful for quick cleaning when you leave the room, and its noise will not bother you; average when you are in the room, but the noise does not bother you; and practically inaudible when you sleep.

But with convenient control, not everything is so simple, because someone likes to set different parameters manually, while someone likes to press one button and forget about everything. Therefore, the most preferable one is the one that has both a manual mode and a fully automatic one, so that all members of your family are satisfied.

Conclusion 4: Optimally, the device should have several modes of operation, incl. one very quiet no more than 20 dB, as well as manual and automatic control modes.

Considering all these parameters, the following are the best air cleaners:

AiC AP-1101/1103

Optimal choice without replaceable filters:

If the problem of odors is not very urgent, but humidification of the air is necessary, then air washing may be the best air purifier. Sinks well humidify the air due to the large surface area of ​​constantly wetted plates and purify it by running it through a "water bath", while dust and other contaminants adhere to the plates and are washed off with water during the movement of the drum. Sinks remove dust and other allergens worse than air cleaners with HEPA filters, they can remove only unstable odors, they cannot cope with chemical compounds, but they also have serious advantages.

The chemical industry is advancing by leaps and bounds, and today thousands of anthropogenic compounds are involved in technological processes, many of which have, to put it mildly, an unpleasant and often disgusting "odor".

In this regard, the interest of industry representatives in equipment that can effectively carry out such a process as cleaning or air filtration from odors.

Moreover, in the context of considering the topic of air pollution with foul-smelling compounds, both aesthetic and toxicological aspects should be noted. In addition to simple discomfort, caused, for example, by a small concentration of skatols, mercaptans or amines in the workshop, the smell may indicate the presence of much more hazardous substances in the industrial atmosphere.

The origin of the word "mercaptan" is interesting. It is formed by abbreviating an English expression Mer cury Capt ure (capture of mercury) due to the ability to effectively bind mercury-containing compounds.

In addition, it should be borne in mind that many of the dangerous, carcinogenic and mutagenic gases and liquids are odorless (and some - for example - smell good), being invisible but ruthless killers.

Therefore, if there is the slightest suspicion of a leak of hazardous substances, you should immediately think about updating or modernizing the current filtering infrastructure.

LLC PZGO has been holding a leading position in the Russian market for gas cleaning equipment, industrial aspiration and ventilation systems for more than three decades, the average efficiency of which in terms of cleaning (filtration, separation and utilization) of unwanted gases, aerosols, mists, 100% .

Odorous substances as clear markers of pollution, some MPC

In general, the presence of an unpleasant "spirit" in an industrial atmosphere suggests that the substance already dispersed, left the place of its deployment, and in this case it is possible to clear the air from the smell only through centralized ventilation. Moreover, sticky and oily aerosols that have coated production surfaces often cannot be removed with an air suction unit.

In order to prevent odorous / undesirable components from entering the workshop or site's aerial climate, it is necessary to install filters and ventilation ducts exactly in those places where the concentration of the pollutant is maximal: above the digesters of a food factory, heating / frying lines, above mixing tanks, at the exit of the spray booth. , above the laser machine.

Table: MAC of some hazardous and foul-smelling chemicals

Many of the above compounds are familiar to everyone: vinegar, ethyl alcohol, camphor oil, naphthalene, acetone. But it is better not to get acquainted with such substances as phosgene (which, by the way, smells like rotten cut grass).

Despite the fact that phosgene was developed as a weapon of mass destruction for the fronts of the First World War, it is still used today in organic synthesis enterprises. Phosgene is one of the key components in the production of polycarbonate. There is NO antidote for phosgene poisoning.

Filters and equipment for neutralizing industrial odors

Considering filters for air from odor, it should be noted that the capture of industrial odorants is carried out by the same types of equipment that are designed to provide "traditional" air cleaning from harmful or unwanted impurities. The logic here is straightforward: there is no substance - there is nothing to smell. The more efficiently the pollutant is removed from the air, the more favorable (and safe) it will be for breathing.

Thioketones - Probably the strongest smelling compound. You can smell thioacetone, for example, when it is contained in the air in a volume ratio of 1/10 * 12. To make it clearer, compare a piece of paper with the area of ​​the Moscow region

Wet (absorption) and dry (adsorption) approaches are one of the most extensive and important areas in gas cleaning. Let's evaluate both methods using the example of removing some common foul-smelling contaminants.

Hydrogen sulfide odor removal methods

Hydrogen sulphide is clearly felt even at a concentration of 1.5 mg / m3, (and the lethal concentration is only 0.1% of the inhaled air). The danger of H 2 S lies not only in its toxicological effect, but also in its ability to create explosive mixtures with air.

Filters for the smell of hydrogen sulfide are especially in demand due to the fact that at a certain concentration hydrogen sulfide paralyzes the olfactory nerve, and the smell of rotten eggs ceases to be felt by a person. At the same time, the negative effect of the gas on the body continues.

Chemical odor removal can be carried out using both wet absorbers and dry adsorption towers. Each deodorization method has its own advantages, which are fully revealed in specific production conditions.

Please note that the functionality of the devices described below correlates with the retention any other foul-smelling, toxic or technologically undesirable components of the air stream.

Wet sorption in scrubbers and absorption plants

Absorption is the process of retention of a gas component in the volume of a liquid reagent. In the case of hydrogen sulfide, alkaline solutions demonstrate the maximum reagent efficiency.

Private example:H 2S +NaOH (sodium hydroxide solution) →NaHS (sodium hydrosulfide) +H 2O

Sodium hydrosulfide obtained as a result of air-cleaning activities can be economically disposed of. As for the physical aspects of the interaction of the pollutant with the absorbent, the following variants of the apparatus are possible (the choice of which depends on the conditions of the site and the wishes of the Customer).

For detailed information on the devices, their characteristics and principles of operation, please follow the blue links (they will open in a new window).

1. Capturing gas c. The working chamber is filled with stationary bodies with a large specific surface, on top of which an alkaline solution is sprayed. Deodorization takes place at the interface of the liquid microfilm;
2. Capture of hydrogen sulfide, (especially in combination with other pollutants), in (APID). The working chamber is filled with polypropylene balls, which randomly move (boil) in an alkaline solution;
3. An air purifier for smoke and odors can be made as. The main contaminant retention factor (disinfectant) is a self-sustaining layer of unstable foam formed on the surface of the supporting perforated trays due to the passage of air through the holes.

Each of the units, when the correct absorbent is selected, is capable of showing odor cleaning efficiency in the range of 96-99.9%.

The advantages of wet cleaning carried out by scrubbers of the ShV series are:

• Ability to process humid environments without preliminary drying - aerosol mists, vapors, fumes, emulsions, suspensions;
• Possibility of parallel operation as a dust collector, including for the retention of sticky, viscous, sticking high-concentration dusts, as well as ash, soot (combination of mechanical and chemical deactivation of the flow);
• Processing of high-temperature media, including those with high chemical activity (sulfur oxides, nitrogen oxides, HCl, H 2 SO 4, carbon disulfide, H 2 S);
• Sorbent filters with rational selection of the reagent can generate valuable sludge;
• Self-cleaning, no need to replace any functional elements;
• Flexibility, simplicity, quick reconfiguration, full automation of work, affordability, durability and reliability.

Deodorization of gases in adsorption blocks

Dry adsorption is another type of chemical odor neutralization. has its own important features:

• The method is classified as regenerative. This means that the captured components can be subsequently recovered from the adsorbent (for example, after the treatment of hydrogen sulfide, elemental sulfur of high purity can be recovered from the activated carbon);
• A wide range of sorbents allows you to effectively hold the widest range of odorants;
• The adsorbers are not intended for processing humid streams (in the case of processing humid media, in order to maintain the nominal efficiency of the device in front of the column, a desiccant is required);
• There is a need for regeneration (blowing) of the absorbent, as well as - periodically - in a complete reboot of the disinfectant (activated carbon, silica gel, zeolite) due to overgrowth of active pores;
• Among other things, it is desirable to install two or more adsorbers at once: one works in the deodorizer mode, the second in the filler regeneration mode.

Adsorbent granules - activated carbon

At the same time, adsorption columns show ≈ 100% efficiency in relation to a variety of gaseous pollutants, which makes it extremely rational to use them as final, sanitary links in multistage systems and complexes of industrial air and gas cleaning.

Deodorization of spray booths

Air purification from paint odors in the spray booth can be effectively carried out using wet scrubbers of the ShV model range.

LLC "PZGO" - breathe easily!

Living conditions in modern megalopolises with a high concentration of street dust, smog in the air require protective measures for normal life and recreation of people. In addition to the hazards coming into the apartments from the street, household dust is also a health hazard. One of the ways to normalize the indoor climate is to install a home air purifier to remove dust.

Air purifier from dust: the relevance of use

An air purifier is as basic a device as a microwave oven or an air conditioner.

The main purpose of the household appliance is highly efficient cleaning of the air in the house from street and household dust, as well as suspended impurities, gases, odors. It is carried out by sucking the air flow into the device, where the air is repeatedly purified. Out there comes out completely purified. Many users, planning home improvement and distributing their budget, doubt: is an air purifier needed in an apartment at all? Unfortunately, today the state of ecology is such that the question becomes rhetorical. The purchase and installation of a household climatic device is justified by the following arguments:

• The air is cleared of dust mites, microorganisms that cause disease in humans and pets.
• Odors, carbon monoxide gases are destroyed.
• Spores of the fungus, scales of keratinized skin, etc. are removed.
• Residents' immunity is maintained.
• Conditions for a healthy lifestyle are created, the risk of ARVI diseases is reduced.
• Allergens are removed.
• The working capacity of people is increasing.

For houses and apartments where small children and people with respiratory diseases live, the question of why such a climatic device is needed should not be at all. Even in spite of the daily wet cleaning, it will not be possible to get rid of the suspended dust in the air. Those. the presence of harmful organisms and mites in the apartment is ensured.

What are the cleaning systems

Choosing an air purifier for dust for the house - which one is better - you need to navigate in the models available in the retail network. By the type of filtration, all devices are subdivided into mechanical, ionic (electrostatic), photocatalytic and combined types.

With humidifying filter

Dust from the passing air stream settles on it. The device is efficient, but requires constant and frequent maintenance. For household purposes, it is practically not used.

Aerofilters

Air is passed through them and leaves the installation back into the room completely free of dust, but not from harmful viruses and other microorganisms.

Coal devices

They belong to devices with a mechanical cleaning method. Economical and easy to use and maintain. Particles of coal neutralize odors, but are powerless over dust and allergens.

Mechanical cleaning

It is also used in Nera filters. The device quickly cleans the air from microscopic dust particles and other inclusions, which reduces the level of allergens in the air to zero.

Devices with ionizing action

Some users are wondering when buying an air purifier - what is an ionizer for? It with high efficiency frees the air flow from fine dust, traces of tobacco smoking, burning, capturing particles less than 1 micron in size. The work uses an electrode that charges neutral air particles and attracts them to itself. Elements of dust, soot from the air settle on surfaces in the house, after which wet cleaning should be carried out. But the filter is powerless against toxic gases, although it fills the room with freshness.

Photocatalytic cleaners

Exposure to dust particles, microorganisms, allergens, toxic gases is provided by UVR and a catalyst. Not only hazardous components in the air are destroyed, but also unpleasant odors. The room is sterilized. But when working, they create noise, consume a lot of energy and are powerless in front of organic impurities.

Combined multistage systems

They work on the principle of complementing some functions with others. This can be cleaning through a system of filters from organic compounds, disinfection followed by ionization. Combined type household air purifiers are considered to be the most effective for home use.

UZU (ultrasonic installations)

With manual or automatic humidity correction. In the second case, the moisture content in the air is monitored by a built-in hydrostat. It starts humidification when its permissible level drops. Widely demanded reliable and trouble-free devices. They can be supplemented with options: backlight, remote control, automatic shutdown, etc. Purify and humidify the air at the same time. This occurs during its passage through a veil of microscopic splashes formed as a result of the splitting of water particles on a vibrating plate.

High-tech devices with a complex control system and a wide range of options are climatic complexes with the functionality of several devices of different purpose, arranged in one case.

Attention! The best air purifier for odors for an economy-class apartment is a conventional charcoal filter. But for rooms with tobacco products, it is better to use a photocatalytic installation for these purposes.

How to make the right choice

Having figured out what an air purifier is for in an apartment, then the right model is selected correctly. This takes into account:

• The area of ​​the room, apartment, depending on the range of the device. It is different for everyone and ranges from 10 sq. up to 150 sq. The zone of distribution of ozone generated by the ionizer especially depends on the size of the room.
• Factors that pollute the air: the required filter or the entire cleaning system is selected according to them.
• The noise emitted by the cleaner. The noisiest devices with a mechanical cleaning system with a built-in fan. The minimum sound level is emitted by the ion cleaner.
• The degree of dustiness of the room. In the case of a high concentration of dust in the air containing organic components (particles of skin, wool), the option of a mechanical installation or an ionic cleaner is most preferable.
• Accommodation in an apartment for allergy sufferers, asthmatics. Household allergens are fought with an ionic and photocatalytic filter.
• Unit dimensions and mobility. A good option if the purifier will be compact and portable from room to room.
• Convenience of control: manual, remote, automatic. Dust collectors are easy to operate. Controlled by on / off buttons. They have a regulator of modes, power and manipulation of the UV lamp (if available).
• A set of required options.

Attention! According to these requirements, a combined unit with a multi-stage cleaning system that removes dust, microorganisms, carcinogens, allergens from the air can become the optimal model of the purifier.

When buying a purifier, the financial capabilities of the user are also taken into account. With any choice, it will be a budget model or a complex combined system, the air in the room will definitely become much fresher than without any purification. Therefore, when planning to equip an apartment or house with the necessary household appliances, do not forget about an air purifier.

Any adult and educated person knows that the air in the city is not only far from natural purity, but is sometimes hazardous to health. And in order to protect ourselves from 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 consider everything in order.

Clean air in the home can be considered a basic physiological requirement. And if you do not live in a clean suburb or at least near a park, then most likely you need an air purifier. Modern manufacturers create and modify such devices in huge quantities, adding the necessary (or not?) Functions of ultrasound, ionization, humidification, and so on, ad infinitum, changing the shape, size and number of filters, thus completely confusing the buyer. Let's see what air purifiers exist now and what they are for.

There are no less myths in the field of air purification than in show business 🙂 But for the most part, all air purifiers consist of a fan that drives this very air through a 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.

Most often they try to combine an air purifier for an apartment with a humidifier, which has already created some confusion between these devices. However, an ordinary humidifier does not purify the air, but only fills it with moisture, and from such devices the proud title of “air purifier” can only be worn by air washing. This type of home air purifier actually “washes” the air by forcing it through the water curtain. At the same time, under the influence of water, dust and other small pollutants in the air settle on the wash discs. Air purification with the help of a sink occurs along with humidification, which adds to the popularity of these gadgets. All air washers work according to the same principle and differ in size, fan power and additional functions. Most often, air disinfection is introduced into the sink. In addition to the desire to introduce as many functions attractive to the buyer as possible, in this case the manufacturers are guided by the principle of compensation - the fact is that the humid environment formed in the sinks is very favorable for the growth of bacteria, harmful microorganisms and fungi, the sink must be constantly looked after and cleaned her 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. How safe such technology is, we have already discussed in another.
In addition, the sinks themselves work quite sedately and calmly, you should not expect from them quick cleaning of the room, removal of odors and the smallest particles of pollutants and allergens.

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 greater. The devices differ in size, performance, design, and most importantly, which filters for air purification 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. The device for dry cleaning systems includes a more powerful fan, which forcibly draws in air from the room and drives it through the filtration system. Basically, these types of filters are found in such systems:

• Coarse air filter. Usually it is a mesh or porous material that is capable of trapping large contaminants such as dust lumps or animal hair.
• Fine filters. They usually look like an accordion-folded fabric or paper material. The filter material has many pores, which, due to unusual folds, are superimposed on each other, forming a fine-mesh non-linear sieve. These filters trap dust particles and most of the allergens.
• HEPA filters. Today, such filters are the most effective for air purification. They trap even the smallest and most harmful particles of pollutants such as PM2.5, tiny allergens such as dust mite secretions, and so on. Considering all this, a HEPA filter for air in an apartment is necessary; without it, the entire cleaning system will be incomplete. We have already described in detail the technology of their work in this article.
• AK filter, it is also an 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 the apartment must include such a filter. Inside the filter there is a special material that literally “pulls in” gas molecules and reliably locks them inside. Some manufacturers make variations of the AK filter, for example, standard and reinforced, 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 are energy consumption and noise level. In reality, a high-quality air purifier consumes no more energy than other household appliances (and often several times less), and the noise generated by the gadget is aerodynamic, caused by the passage of air through the filter system. However, with the help of new technologies and materials and this noise, some models got rid of and now they work so quietly that sometimes questions arise as to whether the device is turned on at all 🙂

Who knows what: additional functions in air purifiers

When choosing which air purifier is best for the home, people usually pay attention not only to the number of filters, but also to additional functions. Let's take a look at the most popular ones.

Air disinfection is most often confused with air purification. It is 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 field of medicine, but it can be very useful in everyday life. Even the best quality home air filter can capture harmful microorganisms, but do 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 a long time, allowing to solve two problems at once - unpleasant odors and the destruction of microorganisms. Unfortunately, the age of this technology has become its main problem - now many viruses and bacteria are already resistant to UV radiation, and such radiation itself is not always safe for humans. We have already considered in detail UV lamps and their scope in another, now it makes no sense to retell the whole history of this issue. If you are using an air purifier with a UV lamp, follow the instructions for use carefully.
• Inactivation of microorganisms. Modern technology that deprives all pathogenic microorganisms of their ability to reproduce, inactivating them with ozone produced inside the device. Thus, the air purifier and air purifier 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 for the decomposition of 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 the Tion air, but we believe that the future belongs to this technology and will soon be used to protect their health in every home.

Also, if we talk about multifunctional gadgets with air purification, one cannot fail to mention. These devices provide a constant flow of fresh air with closed windows, cleaning it at three levels of filtration - protection from coarse dust, thorough cleaning from the smallest harmful particles and HEPA allergens with a filter of class H11 at least, retention of molecules of harmful gases and unpleasant odors. In addition, the breather heats the air up 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 quiet cleaning and heating of air that is already in the room occurs, that is, one device immediately performs the functions
