The kitchen is one of those places in the house where it is really necessary to purify the air, because it contains not only various odors, but also often products of gas decay. There are a huge number of exhaust devices that can cope with this problem. This article will talk about recirculation version of the hoodwhich is also called an air cleaner for the kitchen.
The principle of operation and differences from conventional hoods
A kitchen air purifier is used instead of a hood and works as follows:
- with the help of a fan, polluted room air is sucked in by the device;
- there it passes through a series of filter elements;
- after the purified air mass is fed into the room.
Filters trap the following air pollutants:
- various mechanical particles (for example, dust, animal hair, fabric fibers, etc.);
- products formed after combustion of gas;
- odors (particles of substances that caused their appearance).
The fundamental difference between an air purifier and a flow hood lies in the principle of operation of the devices and the degree of their mobility. The first passes the air mass of the room through the filter system, cleaning it. The hood removes air with impurities from the room through the ducts to the outside. In addition, the air cleaner can be reinstalled in any room, and the hood is a stationary device that is placed directly above the stove to achieve greater efficiency of its work, with a whole system of ways to exhaust air.

Here’s how the air cleaner differs from the hood:
- operating noise level;
- the presence of additional functions;
- the cost of the device itself and its maintenance;
- installation complexity.
These differences are not fundamental and depend on the specific models used. But it is on these criteria that they are guided when choosing devices.
Hoods capable of operating in 2 modes: recirculation and flow are becoming more common. But the price of such devices is higher than single-mode counterparts.
The nuances of installing air cleaners
As mentioned above, the installation of devices for recirculation and flow principles of operation is different. For the hood, you should choose a place so that you can easily connect an air duct and then connect it to a common ventilation shaft. Ideally, it is recommended to purchase an air purifier in combination with kitchen furniture so that its model fits into the design of the room.
The installation process is simple, but a number of such nuances should be taken into account:
- needs to be calculated in advance. outlet locationfrom which the installed device will receive power so that its wire is not stretched and does not come into contact with the heated parts of the stove;
- install an air cleaner before arranging kitchen furniturein order to be able to preliminarily determine the direction and scope of its action, it is convenient to arrange all the constituent elements of the headset around the room.
The optimal distance of the cleaner from the stove is 0.75 m, which meets the requirements of fire safety. This arrangement allows the device to draw in all the vapors coming from the stove.
Connecting the device through an extension cord is not recommended. The best option for the location of the outlet is its hidden placement in the cabinet at the level with the purifier.
Types of filters in kitchen air purifiers
Kitchen air purifiers are often equipped with the following filters:
The first filter is a cassette consisting of several layers of plastic or aluminum. It can be washed with water. The air filter is designed for more complete cleaning and has a fibrous structure. It allows you to trap small particles.
In addition to the 2 considered, a number of models contain a third, carbon filter. It is designed to eliminate odors. The air and charcoal filters need to be replaced at least once every 3 months. This is determined by the intensity of the work of the equipment, entails additional, sometimes significant, costs.
Mobile cleaners can be equipped electrostatic filter. Its essence lies in the fact that an electric field is formed around the electrodes, because of which they begin to attract particles in the air. Some models contain photocatalytic filter, which decomposes organic matter into simple, harmless compounds. The electrostatic and photocatalytic types are relatively expensive, but do not need to be replaced.
Which is better to choose: a recirculating air purifier or a conventional hood
Which is better: an extractor hood or an air cleaner in the kitchen? This question cannot be answered unequivocally, because the choice must be made based on practical expediency. Recommendations in this regard are as follows:
- when cooking is rarely done in the kitchen, and its area exceeds 15 sq. m, then the recirculation cleaner will do just fine;
- if the stove is often used or the kitchen is small, it is recommended to give preference to the hood.
When choosing, keep in mind that the air cleaner:
- can be installed in any room, it is mobile;
- does not remove heat from the house outside during the cold season;
- ready to work immediately after installation and connection to the network;
- maintenance is more expensive than the hood;
- does not interfere with the circulation of moisture.
Maintenance costs can be reduced by purchasing a model with washable filters.
The flow hood is characterized by greater productivity and lower noise level during operation, but requires summing up ventilation ducts. If this is problematic, or the work is associated with significant costs, then it would be preferable to install a recirculating device.
The choice of cleaner must be made, guided by its practicality for specific operating conditions. Among the three types of devices, if possible, it is better to purchase equipment combined type of action. It will remove pollutants from the air, function as an exhaust hood.
