Coal filter for drawing

Kitchen hoods - a necessary item for any kitchen. 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 operation of the devices: drainage to the ventilation duct and air recirculation. 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, it is engaged in filtering the air in the kitchen and returning it back. In these devices, in addition to the usual fat used in all devices, a carbon filter is used. For the hood, this means a 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 for stretching 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 merits of a hood with a carbon filter, one can attribute the absence 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 remains the first - the removal of air from 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, it is often necessary to install an 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 recirculation mode and only in it.

Since the carbon filter for drawing helps to clean the air more indoors, does not require additional installation when installing the device, it is 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 supply of the room with air. Depending on the model of the device, filters are also produced, which can be round or rectangular in shape.

Buying a device for air filtration - a carbon 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. Timely replacement of the filter is a necessary process that can protect the health of the owners of the apartment and their household.
