A cooker hood is a device designed to clean the air of odors, fumes, smoke and other impurities that are formed during the heat treatment of products.
There are two main types of devices. Circulating kitchen hood allows you to clean the air through filters and return it back to the room. Carbon filters are usually used in such devices , which absorb odors, and grease traps that trap soot and tiny drops of fat. The latter variety is made from sintepon or non-woven and needs to be replaced periodically.
A metal reusable cartridge filter is considered more convenient. It is sufficient to periodically remove this consumable from the device and wash it with soapy water. Many device models use two or three grease filters.
The charcoal cleaner must be replaced, depending on how intensely the cooker hood is used.
This period can stretch to two years. Today it is difficult to find air purifiers that work only in the circulation mode, since flow-through devices at a relatively low cost are much more efficient. They, as a rule, also have a circulation mode.
A flowing kitchen hood is able to remove soot and fumes through the building's ventilation system . It is more difficult to install, because it requires the installation of chimneys that connect to the ventilation hole. However, the built-in kitchen hood has high efficiency. It allows you to throw out contaminated air, and also, due to the creation of a differential pressure, to ensure the flow of fresh air.
Flowing devices in their design have only a grease filter, which prevents the accumulation of fat on the blades and walls of the air duct of the device. There are inexpensive models in which there are no filters at all. Such a cooker hood requires more thorough care.
When choosing a device, you need to look at the dimensions and design of the device. However, the main indicator is the bandwidth of the device. The volume of air passed per unit time depends on this characteristic. The efficiency of the fan motor, which varies from 150 to 750 cubic meters per hour for different manufacturers, affects the efficiency of the device. For an ordinary standard kitchen, hoods with a capacity of 300-350 cubic meters are enough.
When purchasing a device, it is necessary to take into account the noise parameters. Although for modern devices this indicator is normal. The cooker hood works with virtually no extraneous sounds thanks to the use of special bearings and acoustic packages.
Many air purifiers have a set of additional functions. Since a cooker hood is mounted on top of the stove with its own hands, it can also be used for lighting. In modern appliances, light bulbs of various capacities are installed, which make the cooking process more convenient and enjoyable.
