is a device designed to process harmful impurities, purify indoor air, and preserve human health. Today, a lot of different models are produced, differing in technical characteristics, operating principle, and cost.
Polluted air purifier for kitchen

Classification of devices

Air purifiers can vary in several ways. Based on the principle of operation, equipment is divided into:

• Devices with an exhaust type of operation;
• Recirculation devices;
• Mixed action air purifiers.

In the first case, the devices collect air impurities and remove them outside the room through the ventilation shaft.

The second option involves treating contaminated air inside the air purifier. In this case, impurities remain on the surface of the filters, and purified air is returned to the kitchen.

Mixed-action devices are equipped with two filtration mechanisms.

According to the type of installation, air purifiers are divided into:

• Dome. They are fixed above the stove and act by removing air.
• Hanging. Also installed above hob and operate according to the recirculation rule.
• Built-in. They are characterized by mixed operation and are intended for installation in kitchen elements.
• Mobile. They operate only in air processing mode.

If we talk about the shape of the devices, they produce hoods in the form of truncated pyramids, cones, inclined and T-shaped devices, cylinder hoods, cubes or devices with a bent corner.

The best modern air purifiers can remove up to 96% of contaminants and odors.

Comparative characteristics

Like any other, air purifiers have pros and cons that influence the choice of a specific device:

1. The easiest installation is for recirculation equipment. Its installation does not require exhaust shafts and complex systems ah air removal. The hood can simply be fixed above the stove, turned on and used.
2. By performance level. Polluted air is released into the atmosphere irretrievably.
3. If we talk about saving heat, the palm belongs to recirculation technology, which prevents the exit warm air through the ventilation pipe.
4. Savings Money, which does not require regular filter changes.
5. The noise level is lower exhaust devices. Purifiers don't have to work hard to force air through dense carbon filters.

When comparing, it is worth clarifying that recirculation devices are not capable of retaining moisture. Its circulation in the kitchen will be at the same level as before installing the hood.

Technical specifications

Each kitchen air purifier has its own technical parameters. To determine whether a device is suitable for a particular room, you need to find out:

The flow-through appliance throws kitchen fumes and soot out

• Working blade size;
• Performance;
• The height of the noise.

Working blade size

Magnitude work surface stationary air purifier must be greater than or equal to the size of the stove. There are three standards for hoods: 60, 90 and 120 cm. Some owners install cooking appliances in the center of the kitchen or form an island from several surfaces. In any option, it is necessary that the air purifier controls the entire slab surface.

Performance

Productivity is the amount of air mass that the device passes through in one hour.

The calculated productivity of the air purifier must be higher than that specified in the technical data sheet.

To determine the calculated indicators, the volume of the room is multiplied by 12 (the air exchange rate for the kitchen) and by 1.3 (the level of air pumping through ventilation in a multi-story building). IN one-story houses the last indicator can be neglected.

Noise

Air purifiers for the kitchen cannot be called low-noise devices. The maximum noise level is 65 dB, but in general, kitchen air purifiers are noisy at 55 dB. For comparison, the same indicator for a refrigerator is 45 dB, and a centrifuge washing machine produces 68 dB.

Type of hood in the kitchen interior

In order to select an air purifier, it is necessary to determine the intensity of pollution and the required functionality. The main requirement for the device is to clean the air and extract harmful substances. The device does not require the installation of ionizers or oxygen enrichers, which will only complicate its maintenance.

Hood or air purifier: which is better?

Trying to answer the question: is a range hood or air purifier better for the kitchen? It is necessary to determine the main differences between the devices. Household kitchen hood is universal stationary device. Air purifiers are portable and can be used to purify the air throughout the apartment.

The main difference between a hood and an air purifier for the kitchen is the independence of the latter. The air purifier does not require the formation of additional exhaust ducts and connection to general house ventilation. For correct operation of the device, only a socket is required.

Installation

Installing an air purifier in the kitchen will only be effective if you take into account the size of the room and its air circuit. If the room has large volumes and the stove is used infrequently, then using the device is quite justified.

A compact gadget is necessary in every apartment

In such cases, the level of pollution is not too high, and the air purifier can do a good job. IN small rooms It is better to install dome or ones that differ in the circulation principle of operation.

Installing an air purifier yourself is not difficult. However, there are some nuances here too:

1. Installation of the device must occur before installation of the headset items. This will help to correctly indicate the direction of its action in the area where the hob is located and to arrange other components on the wall.
2. Calculate the location of the future outlet in advance. The air cleaner wire should not bend, be too tight, or be too close to the heating unit. The best option– if the socket will be placed at the same level with technical means inside the kitchen cabinet.
3. above the hob must comply with fire safety standards. Most suitable distance– 75 cm. This arrangement allows you to capture the entire mass of vapors without being subjected to severe overheating.

A kitchen filter above the stove can be installed instead of a hood if it is necessary to organize the outflow of air regardless of the operation of the air purifier.

The built-in air purification device is completely invisible in the kitchen

Kitchen air purifier kits

Typically, a kitchen hood is equipped with a multi-level cleaning system. Most devices are equipped with two filters:

• Fatty. The element is made in the form of a cassette, consisting of several plastic or aluminum rows. Needs regular washing under running water.
• Air. Designed for more thorough cleaning. It is a fibrous structure that holds. Needs complete replacement as it gets dirty (every 1-3 months).

Some units contain a third, carbon, filter aimed at effective fight with unpleasant aromas.

The bulk of mobile air purifiers are characterized by extensive equipment. In addition to the main options, they can be installed electrostatic filters, creating electric field to attract harmful particles to the electrodes. Sometimes the purifier may include a photocatalytic filter that separates organic matter to safe elements.

Regular and quality care behind the air purifier will significantly extend the life of the device.

The device can only be cleaned after it has been de-energized! You can remove grease from a kitchen hood using a commercial detergent, which must first be sprayed over the surface, allowed to stand for a while and thoroughly removed with a damp cloth.

Folk remedies will help remove grease from kitchen hoods. For example, you can remove dirt with vinegar or lemon. To get results, you need to treat the surface with them, leave for a while, and then rinse off. clean water. Universal folk remedy for the fight against fat is considered concentrated laundry soap, which needs to be grated and filled with water. The resulting solution is applied to the hood and then washed off with clean water.

You can clean the filter from the hood in the kitchen with modern detergents. If you don't have them at hand, use in a simple way, which will remove grease from any metal object:

• Pour water into a saucepan, bring to a boil and dissolve half a glass of salt in it;
• Place the filters into the boiling liquid, allow the grease and dirt to dissolve, and remove the pan from the heat;
• To consolidate the result, place the filters in a solution of half a glass ammonia and 3.5 liters of water.

You can use the same methods to clean the kitchen hood grate.

Air purifier models

Today, many devices are produced, main task which is air purification in the apartment.

WATCH THE VIDEO

The Hephaestus kitchen hood is distinguished by two operating modes, three-stage fans, and the presence of aerosol and carbon filters.

The Acro kitchen hood is another example of modern air-purifying devices with varying prices, designs and technical parameters. The equipment has received many positive reviews and is widespread among ordinary buyers.

Air purifiers for the kitchen above the stove - types and criteria for selection.

Combustion products, soot and carbon monoxide. At the same time, a kitchen hood allows you to get rid of cooking odors. in the kitchen it is always hung above the stove, because this is where all the gases and unpleasant (as well as pleasant) odors are concentrated. The kitchen hood has different names. You can often find both the common name of an air purifier and a kitchen exhaust fan or module. Depending on the name, there will be no fundamental difference in the operating mechanism, but there are differences in throughput and final design.

Types of air purifiers for the kitchen

In the kitchen, a hood is needed to purify the air and remove foreign odors. This occurs due to the air draft created by the fan. Looking under the decorative body of the equipment, you can see one or more engines with impellers. Also one or more filters.

Modern air purifiers for the kitchen can be:

— Circulating. The air is cleaned using filters and then returned back to the room.

- Flow-through. Kitchen fumes and soot are thrown away. This happens through the external ventilation system building. Installation of such a hood will be more difficult, because you need to make a chimney pipe and connect it to ventilation hole. But such an air purifier works more efficiently. After all, the natural traction force enhances the air exchange created by the fan.

How to make the best choice?

When buying an air purifier for the kitchen above the stove, you need to pay attention not only to specifications. The size of the kitchen is also important, appearance the device itself. Throughput is performance. Main characteristics, which you need to pay attention to. The higher the capacity, the more air the hood can clean within an hour. Average productivity should be 150-700 cubic meters per hour.

Important! To determine the required performance for a specific room, you should remember that according to sanitary standards The optimal air exchange for the kitchen should be as follows. Within an hour, the air volume should change at least 10 times.

All good devices must have from two to five power levels. A useful feature is the smooth adjustment in wide range. Maximum power is needed when frying fish, if some dish is badly burnt.

Why filter air?

Some people wonder why air filtration is needed if it is being released outside anyway. It all depends on the type of device. In circulation mode, the filter can be used to retain the smallest droplets of fat and soot, as well as absorb odors (charcoal).

As for flow-through devices, only the first type of filter is installed in them; carbon filters are not used in supply air purifiers at all. Because the air is released and, indeed, no additional purification is required. But there is a point in a grease filter. After all, without it, grease would accumulate on the fan blades, slowing down the operation of the entire system.

Interesting! The cheapest flow hoods They don't have any filter at all. But they require careful care: it is necessary to regularly clean off grease from the ventilation hood and other parts.

Just because your kitchen air purifier is quiet doesn't mean it's slow. Simply, the purchased model is of high quality and will not tire you with its noise, which has a good effect on general condition. Each owner can choose the design to suit their specific requirements. But you shouldn’t make a fundamental choice based on design. First of all, of course, the production characteristics described in this article are important.

It's no secret that even with regular and thorough cleaning of the house, the air in the apartment is saturated various contaminants: bacteria, microscopic particles of epithelium, plant pollen, combustion products formed as a result of operation kitchen stoves. The only one the right decision in the current situation is to install a modern “heavy” air purifier for the kitchen.

Installation of such modern devices allows you to significantly increase the comfort of living indoors, get rid of various types ailments: increased fatigue, headaches, allergic reactions, respiratory diseases and so on.

Many products, one principle

Each specialized supermarket is replete with a variety of household appliances. Qualified employees will be able to tell you quite accurately about all the advantages and disadvantages of each model, the specifics of production, work, manufacturer, and justify the cost of the product.

However, despite the large flow of information, choosing an air purifier is much more banal and simpler. A large assortment modern purifiers air is based on only 2 basic principles of operation of devices: exhaust and recirculation.

It follows from this that devices are divided by type of operation.

• Exhaust type air purifiers. The operation of products of this type is based on the irreversible removal of various impurities and odors from kitchen area into the ventilation shaft and then into the environment.
• Air purifiers are recirculation type. The operation of products of this type is based on the forced emission of air through filters. It should be noted that the air itself does not disappear anywhere, but is only cleaned of odors, dust and harmful substances, leaving them in the structure of the filters themselves.
• Air purifiers mixed type. The operation of mixed-type products implies the ability to use common functions depending on need and appropriateness.

Range

For recirculating kitchen air purifiers, there are several of the most common types of replacement filters used, including:

1. Mechanical. Installed to capture large debris and pet hair. Such filters are usually a mesh with small cells. Mechanical coarse filters are installed on almost all models of modern air purifiers. To filter the air from smaller particles of pollen, cement or asbestos dust, the installations use more sensitive fiber filters.
2. Electrostatic. Captures most microscopic particles floating in the air. Such filters work according to the law of attraction of electrical charges of different polarities. The filter operates by creating a corresponding stable electric field, which attracts dust particles. Although electrostatic air purifiers do not require regular replacement, they do require periodic wet cleaning.
3. Photocatalytic. Such filters effectively decompose the smallest particles, the size of a large molecule, regardless of its production. The action of such filters is carried out using photocatalysis technology, that is, harmful impurities of organic origin are decomposed to the level of absolutely harmless air components.
4. Coal. Such filters are used to purify the air from household gas contaminants and unpleasant odors. It should be noted that such a filter cannot absorb all gaseous compounds harmful to humans, in particular carbon monoxide.

Important! To achieve maximum cleansing kitchen space from harmful substances, a combination of several filters is often used.

Advantages

Every modern technical device has its advantages and disadvantages, knowing about which will make it much easier to make a purchase. So let's get started.

Advantages of a recirculation hood system:

1. Ease of installation. Such Appliances does not require the installation of additional ventilation shafts and complex systems for removing polluted air. The operation of the device begins immediately after the purifier is installed above the stove and connected to the electrical network.
2. Valuable heat will not leave the walls of the kitchen during the cold season.
3. It perfectly cleans the air, trapping all odors, fumes and fats.

Advantages exhaust system kitchen ventilation:

1. The silent operation of the device is due to the easy and unhindered removal of “heavy” air masses through special ventilation shafts.
2. Saving on accompanying materials. In such systems there is no need to periodically change and install new filters, which are by no means cheap.
3. The high efficiency factor is based on the principle of absolute elimination of “heavy” air and moisture in the air.

Installation of the unit in accordance with individual parameters

To make the right choice of the required household equipment for the kitchen, you should decide on several important criteria. Having decided on the parameters, it will be much easier for you to not only right choice, but also avoid unnecessary costs. So let's get started.

• We define right size working surface. Length working area the hood should be equal to or slightly larger than the working surface of the stove. This condition must be met so that all odors generated go directly into the hood and do not spread throughout the kitchen. Today there are 3 standard sizes hoods: 60, 90 and 120 cm. There are cases when the stove is placed in the center of the kitchen. Then a hood is required custom sizes working surface.
• We calculate productivity. Productivity is determined by the volume of air that the air purifier is able to process in 1 hour. There are 2 productivity: declared and calculated.

Important! Specified performance in technical passport should always be greater than calculated.

To determine the estimated productivity, you should calculate the volume of the kitchen, then multiply this number by 12 and 1.3.

12 is the air exchange rate for the kitchen room. 1.3 is the coefficient for pumping air through ventilation in multi-storey buildings. In private one-story residential premises, the coefficient of 1.3 can be neglected.

• We choose the most comfortable and permissible level noise. The noise level of modern air purifiers is within 55 dB. Although such noise cannot be ignored.

Equipment installation

For correct installation equipment must always be followed general rules, which are indicated in the technical documentation.

The process of installing equipment must be taken with full responsibility. That is why the markings of all fasteners must be additionally checked using a building level. The correct horizontal installation position is not only aesthetic issue, but also the key to rational functionality.

If for installation it is necessary to lay outlet channels, then preference should be given to channels made of PVC material.

Beauty requires care

For the manufacture of hoods, metal is most often used, which is quite easy to care for. It should be noted that filters used in recirculating air purifiers are not subject to such care.

The filter can be cleaned either independently or by dishwasher. However, if you clean it in the car, you must first wash its walls to remove food debris. Otherwise, the damaged filter can simply be thrown away.

Choosing an air purifier is a delicate matter

For optimal selection air purifier in the kitchen, you should take into account all the features of the room and the possibilities of laying out the equipment ventilation shaft for an exhaust type device. If you decide that you want to install a recirculation type hood, then questions regarding the air duct and its installation are not affected in principle.

The best option for purchasing a hood is a general purchase with kitchen furniture. However, not everyone can afford such luxury today. Much more often, all components of a kitchen set are purchased at different times or in different places. After which the installation and adjustment of the containers is carried out.

Let's consider perfect option purchases when you have the opportunity to purchase kitchen furniture with built-in household appliances. In this case, the specialists of the furniture salon will carry out a professional selection of the model of the air purifying device, taking into account the size of the kitchen, work surface and furniture.

When choosing an air-purifying device, you are required to decide only on the type of desired placement of the hood on the kitchen furniture.

Accommodation types:

1. Hanging. The main advantage of this model is simple installation directly to furniture installation. Devices with such mounting are often small in depth and work well when using several air purification filters.
2. Built-in. Such devices are built into kitchen furniture using high-quality fastening. They blend perfectly with it (in color and texture). As a rule, such hoods are made in the same style as kitchen furniture and are almost invisible.
3. Fireplace (in the shape of a dome). The appearance of such a device resembles a fireplace chimney, which fits perfectly into any interior style of the room. Such air purifiers can be of only ventilation or mixed types.

Nowadays, combining a kitchen with a living space, forming a studio, is especially popular. Thus, on the one hand, there is visual increase space, and, on the other hand, the spread of odors from the stove throughout the entire territory.

To prevent the latter, experts recommend installing a high-quality air purifier for the kitchen, which will be selected according to the size common area and personal wishes of the owner.

Undoubtedly, modern models Air purifiers for the kitchen are technically advanced devices that today purify the air much more effectively than their predecessors. In addition, modern models have perfect designs, allowing only to complement and favorably emphasize the interior details of the kitchen space.

A kitchen air purifier removes exhaust air outside or cleans it in recirculation mode. You can install the hood and air duct yourself.

Everyone knows that when cooking food in the kitchen, unpleasant odors. Moreover, if you have to cook at gas stove, exhaust carbon monoxide collects in the room. As a rule, this leads to the fact that housewives have to fry and bake at open window, which is not always convenient, especially in cold weather winter time. Kitchen air purifiers, the popularity of which is only growing every year, will help correct the situation. Most often, a kitchen air purifier is understood as a conventional hood that removes exhaust air outside or cleans it in recirculation mode. You can install it yourself, the main thing is to choose the right model.

Types of hoods

There are three main types of hoods: flat, built-in and fireplace. Each of these types has characteristics and is suitable for various spaces.

• Flat – the most budget and common option. As is already clear from the name, they are distinguished by their small height, which, depending on the shape of the device, can reach 7-15 cm. They come with a set of fasteners, installation instructions and an adapter to which the corrugated air duct is attached. The power of such air purifiers for the kitchen is usually small, as a rule it does not exceed 200-300 m³/hour. This is enough for an area of ​​8-10 squares. A feature of such models is an open air duct in air exhaust mode.
• Built-in. Such models are almost completely built into the cabinet; only the retractable front panel is visible. They are larger and usually more powerful. mostly hidden inside the closet.
• Dome. These include a fairly large group of air purifiers. Unlike built-in ones, not only power indicators and dimensions are important, but also appearance. The dome hood is completely open and occupies quite a significant part of the wall. As a rule, it is equipped with 1-2 decorative boxes, capable of hiding air ducts. Air purifiers of this type are characterized by a wide base, gradually tapering towards the top, in the form of a dome (hence the name). They can be made of stainless steel or painted metal, combined with glass or wooden inserts. The power of such devices can reach 1000 m³/h.

How to determine the required air purifier performance?

It is determined by the formula: “Room volume * 10 = Productivity”, where 10 is the air exchange rate, i.e. a number indicating how many times per hour the air in the room is completely renewed. Let's say the kitchen area is 9 m². Standard ceilings are 2.5 m. Then the minimum required power of the air purifier is: 9 * 2.5 * 10 = 225 m³/hour.

If a corrugated hose is attached to the hood, through which air will be removed, then at each turn of the hose the power will drop by about 10% - this should also be taken into account.

Of course, there are more complex calculations that take into account the need to pump air through air ducts or the volume of furniture in the room, but the average person has no need to delve into them. The above formula is enough to estimate the required performance before purchasing.

Dimensions

There are four standards for the length of hoods: 50, 60, 90 and 120 cm. In Russia, air purifiers of 50 and 60 cm are popular. 90 and 120 are extremely rare. The model is selected so that its length matches the width of the slab. If the stove is 50, then the kitchen air purifier should be 50. Air purifiers of 90 and 120 cm are most often selected for large ones, installed on a separate island, or for production. Such units are quite bulky and difficult to install with your own hands without outside help.

Principle of operation

Some kitchen air purifiers can only operate in exhaust mode, some only in circulation mode, but most models combine both principles.

If the air purifier operates in exhaust mode, then all exhaust air is completely removed from the room through the air ducts. If the model is set to recirculate, then the air is taken in, passed through a filter system, and then returned to the room.

As usual, each of these cleaning methods has its own pros and cons. The advantage of exhaust is that the air is completely removed - this is much more effective than cleaning through filters. On the other hand, this operating principle requires more serious installation, not to mention the fact that corrugated hoses do not look very aesthetically pleasing and take up a lot of space.

Models operating in recirculation mode take much less space, since they do not require any additional connections. They are very easy to install - just drive two self-tapping screws, hang the hood on it and plug the cord into the socket. But the efficiency of such purifiers is significantly lower, and owners will have to periodically spend money on replacing filters.

Filters for such hoods come in two types: universal and branded. Universal ones are a fibrous sheet impregnated with carbon, which absorbs unpleasant odors. This filter is placed on the grease filter and pressed with fasteners. The branded one is usually screwed directly onto the motor. Its carbon layer is much thicker, so it will purify the air better, but the cost of such a filter is higher. Depending on the model, filters must be changed every 3-6 months.

How to switch the hood from exhaust mode to recirculation mode?

Almost all air purifiers on the market can operate in two modes. In exhaust mode, the air exits through the outlet at the top or rear of the hood and then through the air ducts into the ventilation. To switch the device to recirculation mode, you need to close the outlet with the plug included in the kit and move the lever to change the direction of air movement. A kitchen air purifier configured in this way can be attached directly to the bottom wall cabinet. However, it should be mentioned that flat models are usually switched this way. Built-in ones, which in any case come with ducts and air ducts, do not make sense to reconfigure.

Installation

You can easily install the hood with your own hands. The device usually comes with installation instructions and a sheet with markings for fasteners. It is easiest to attach a model operating in recirculation mode; with an air purifier in exhaust mode, you will have to tinker a little longer.

Installation takes place in several stages:

• mark the wall and install dowels or screws;
• hang the hood;
• then the air ducts are secured: an adapter is installed, one end of the corrugated hose is attached to it, and tightened with a clamp;
• a grille with an adapter is attached to the ventilation hole, the second end of the corrugated hose is put on this adapter and also tightened with a clamp of the appropriate diameter. The hood is ready for use.

This is far from the only option for installing a hood. Much depends on the specific model, on the location: near the wall or in the center.
