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. Fixed above the stove and act by removing air into exhaust ducts.
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.

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

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.
By performance level the exhaust design is in the lead. Polluted air is released into the atmosphere irretrievably.
If we talk about saving heat, the palm belongs to recirculation technology, which prevents the exit warm air through the ventilation pipe.
Saving money guaranteed by the exhaust system, which does not require regular filter changes.
The noise level is lower with 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.

Air purifiers for the kitchen

Air purifiers are more efficient in operation. They really purify the air, thanks to built-in HEPA filters, and are not installed above the stove. These are free-standing devices. But not all of them are equipped with a fine filter; there are different types of models. Depending on the type, the air can simply be cleared of dust, or it can be ionized.

Air purifiers with an aqua filter also produce air humidification, which is beneficial for the lungs and respiratory tract.

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.

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.

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 the centrifuge for a washing machine produces 68 dB.

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 resulting from the use of cookers. 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 of 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 wide range of modern air purifiers are based on only 2 basic operating principles: 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 the kitchen 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 cleansed of odors and dust 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:

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.
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 an appropriate stable electric field around it, which attracts dust particles. Although electrostatic air purifiers do not require regular replacement, they do require periodic wet cleaning.
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.
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 purification of the 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:

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.
Valuable heat will not leave the walls of the kitchen during the cold season.
It perfectly cleans the air, trapping all odors, fumes and fats.

Advantages exhaust system kitchen ventilation:

The silent operation of the device is due to the easy and unhindered removal of “heavy” air masses through special ventilation shafts.
Saving on accompanying materials. In such systems there is no need to periodically change and install new filters, which are by no means cheap.
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 you need a hood to suit the individual dimensions of the 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! The performance indicated in the technical data sheet must always be greater than the calculated one.

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 acceptable noise level. 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 building level. The correct horizontal installation location is not only an aesthetic issue, but also a guarantee of 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 When installing an air purifier in the kitchen, you should take into account all the features of the room and the possibility of laying ventilation shaft equipment 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 the ideal purchase option 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:

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.
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.
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 of the common room and the 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 ideal designs that can only complement and highlight the interior details of the kitchen space.

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

Combustion products, soot and carbon monoxide escape from the kitchen through the hood. 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 decorative case 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 occurs through the building's external ventilation system. 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 and the appearance of the device itself are also important. Throughput is performance. Main characteristics, which you need to pay attention to. How throughput higher, 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. Useful feature is smooth adjustment in a wide range. Maximum power needed in cases of 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-through hoods do not 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.
