Free your kitchen from fats and bad odors

Filters for the hoods are necessary to eliminate odors and retain the grease that is generated when cooking. In this way they help keep the kitchen air clean.

The kitchen hoods can be of two types:

– With smoke outlet or aspirants: These hoods have a conduit that goes through the wall or wall through which dirty air is expelled, vapors and gases from cooking. They always incorporate an aluminum filter that comes standard.

Depending on your attack, the bells need filters of different types:

– Without exit or filtrantes: They are the bells that are installed when there is no possibility of installing a duct to evacuate the air to the outside. In this case the function of the hood is to retain the grease and odors. Bells of this type are those that use activated carbon filters.

Depending on your attack, the bells need filters of different types:

– One metallic: Made with aluminum mesh. It is the grease filter, which is incorporated as standard in all the hoods.

– Another activated carbon: It is a filter that serves to clean the air by trapping odors on a porous surface (absorbs grease, steam and odors), so it filters the dirty air and returns it to the kitchen already renovated. It has a limited shelf life, it is disposable. It is very easy to place. They can be installed in the great majority of the hoods without smoke outlet and their sale is independent of the hood.


The hood filters have to be checked and cleaned frequently because the grease and steam in the kitchen make them dirty. In this way, if the dirt accumulates for a long time the filters will no longer be able to fulfill their function and will not absorb the dirt.

In addition, they have to be renewed every so often, always depending on the frequency with which the kitchen is used. For normal operation (between one and two hours a day) it is advisable to change the filter once a year if it is of the metallic type; and every 3 months or 6 months (depending on the use and cleaning you practice) if they are activated carbon. There are modern models of bells that have an indicator that warns when the filter is clogged and you should proceed to clean it or change it.

The filters eliminate odors and can be of two types: extraction or re-circulation.

– Aluminum or stainless steel filters can be cleaned with warm water and a mild detergent or soap, although there are also specific sprays for this cleaning. You can use a soft bristle brush to remove the accumulation of grease and dirt. Finally, rinse the filter well and put it back in its place. Some can be washed in the dishwasher (always without salt), if specified by the manufacturer.

– The carbon filters are cleaned with a damp cloth. You can not submerge them in water. This type of filters must be changed once a year to continue fulfilling its function and to avoid the risk of fire, since the accumulated fat can burn if it ignites a spark.
