Coal filter for drawing

Kitchen exhaust is a necessary item for anykitchen. It helps to save the room from the accumulated odors, to refresh the air and create a favorable atmosphere. For its operation, you need a carbon filter for drawing, about what these devices are like, how to make the right choice when buying will be discussed in the article.

Principle of operation of the device

There are two modes of device operation: Venting to the ventilation duct and recirculation of air. Standard is the first, when the extract from the kitchen air directs to the ventilation, and then - to the street. To ensure its operation, it is necessary that the kitchen has a ventilation duct located near the hood. And necessarily the inflow of air must come from outside. Otherwise, the pressure in the room will be greatly reduced and the air intake will be carried out from all possible places.

The second mentioned mode is recycling,is engaged in filtering the air in the kitchen and returning it back. In such devices, in addition to the usual fat used in all devices, a carbon filter is used. For stretching, this means better work, so that all evaporation and odors that are in the kitchen when the food is being cooked are filtered.

Advantages and disadvantages

In addition to quality work, such filters forHoods have their drawbacks, which include the need for frequent shifts. They are designed for one hundred twenty hours of work. These figures may vary depending on the capacity of the device, the frequency of its use in the kitchen and the air pollution in the room. But, as a rule, carbon filters need to be regularly changed (after three to six months of work). You can not wash it. The second drawback of their use is that in the extract, passing through a dense filter of air, the power is reduced by an average of twenty to thirty percent.

To the advantages that hoods withcarbon filter, it can be attributed the lack of the need to connect the device to the ventilation duct. No need to provide additional airflow into the room. And the process of filter replacement is simple enough, for which there is no need to call the wizard.

The best option is the first - the air outletfrom the kitchen to the street. But in this case, too, there are some disadvantages. For example, the length of the duct affects the performance of the hood, each extra meter will reduce by ten percent the efficiency of the device. When installing the device, often install the air duct of a dimmer that does not match the hood, and not a smooth, but a corrugated pipe. Because of it, the device works noisily. The motor wears out quickly. The regime of air recirculation in the kitchen should be considered as an alternative and not without its advantages. It is resorted to in the event that there is no ventilation duct. Design models of such devices operate in the recirculation mode and only in it.

Since the charcoal filter for stretching contributes tomore fine cleaning of the air in the room, does not require additional installation when installing the device, more accessible in operation, consumers are increasingly turning to it. In addition, when installing a hood that works in recirculation mode, ventilation remains free, which contributes to better room supply with air. Depending on the model of the device, filters are produced, which can be round or rectangular in shape.

Buying a device for air filtration -charcoal filter for drawing, it is worth buying it in several copies at once, so as not to be mistaken with the model for further purchases. In order to find out whether it's time to change the filter, a special indicator is installed by the manufacturers on the device. The timely replacement of the filter is a necessary process that can protect the health of the owners of the apartment and their household.
