Charcoal filter for cooker hood

The preparation of everyday lunch and festive dishes is accompanied by the appearance of various flavors that quickly spread throughout the apartment. Many of them are unpleasant, especially when frying foods. To get rid of suffocating smells and children, a cooker hood with recirculation helps. It purifies the air in the room, giving it freshness. Its main working element is a filter for a kitchen hood, made on the basis of activated carbon. Thanks to its absorbing properties, the smells of burnt cutlets and rancid oil, the aroma of onions and spices are easily eliminated.

Characteristics and principle of operation

The design of the air cleaning element consists of a plastic casing in the form of a rectangular or round cassette and an absorbent that is held inside by a special mesh. Activated carbon can be in granules or crushed to a powder state.

The following types of coal are used for its manufacture:

• stone;
• coconut;
• peat.

They differ in their structure and distribution of pores of various sizes. Materials with a large number of micropores are best trapped in odors.

In addition, the carbon filter can be filled with coal obtained by chemical treatment.

Since the process of absorption of unpleasant odors is carried out due to the porosity of the material, the degree of purification depends on the amount of filter substance and the density of filling. The larger the area of ​​the particles absorbing odors, the better the operation of the device.

To protect the absorbent from large particles, the hood design is equipped with a grease filter. If its functioning is not effective enough, then they will accumulate in the micropores of activated carbon. This will lead to premature saturation of the absorbent material with contaminants, resulting in the need to replace the filter. To extend its work will help some of the techniques that prevent caking of powder or granules inside a plastic case.

Usually a carbon filter is not included. hoods and purchased separately.

Advice! To increase the life of the charcoal filter, it is advisable to leave the hood turned on for about 5-10 minutes after cooking. During this time, residual moisture that may cause caking of the coal will evaporate and will not damage its protective properties.

Benefits of using

The popularity of kitchen hoods with a carbon filter is due to the effectiveness of the element for air purification, and for their operation does not need a connection to the ventilation system. In addition to this design:

• characterized by ease of installation, operation and maintenance;
• does not require ventilation of the room.

The compactness of the device allows the production of hoods of various shapes and sizes. They can be either built-in in kitchen equipment, or in the form of individual items. The latter option is often used when installing the plate separately from other elements of the headset.

Equally important is the low cost of the carbon filter, so that replacing it does not harm the financial condition of customers. You can purchase coal separately, and then restore the element for air purification according to a certain technology.

Operational Features

For the carbon filter to work effectively, it is enough to keep the hood body clean and remove grease and dust from its surface in a timely manner. As it becomes contaminated, the absorbent becomes denser and its protective properties decrease. In this case, a filter change is required.

Typically, this operation is carried out every 4-6 months, focusing on the air quality in the room.

Advice! Buying a hood with a filter reminder function will eliminate the need to regularly check its condition.

Replacement algorithm

First you need to disconnect the hood from the network to ensure the safety of work. Then perform the following steps:

• remove the grease filter;
• remove the carbon filter from the cartridge;
• install a new cleaning element, and the correct installation is confirmed by clicking;
• reinsert the fat catcher.

After all operations, turn on the hood and check its operation. If during the air purification process there are no vibrations and extraneous noises, then the exhaust element is installed correctly. Otherwise, the design should be disassembled and all the steps repeated again, strictly following their sequence.
