Extractor filter systems
Extractor hoods are an important component in the kitchen, removing cooking vapours and odours to create a pleasant cooking environment. To do this job effectively, filter systems are an essential part of cooker hoods. There are different types of filter systems, such as metal grease filters, activated carbon filters and plasma filters. Metal grease filters are the most common and consist of a metal mesh that filters grease and other particles out of the air. Activated carbon filters absorb odours and other pollutants, while plasma filters ionise and thereby remove particles from the air. Depending on your needs and preferences, different filter systems can be selected for cooker hoods.
What are the different types of filter?
The most common part you will need to change in a cooker hood is the filter. You can usually replace it without any specialist knowledge. Depending on the type of extractor hood you have, you may need up to two different filters. Every extractor hood, whether recirculation or exhaust, has a grease filter. If you have a recirculation hood installed in your kitchen, you will also need an activated carbon filter to clean the air in the kitchen before it
Activated carbon filter
What applies to the grease filter also applies to a similar extent to the activated carbon filter. If you have a recirculation hood in your kitchen, you will need an additional activated carbon filter to filter cooking vapours before they are returned to the air in the room. Unlike grease filters, these filters cannot be cleaned but must be replaced at regular intervals. Experts and manufacturers recommend replacing them after about six months.
Defective filters can provide a breeding ground for germs and bacteria, which in the worst case can have negative health consequences for kitchen users. The advantage of activated carbon lies primarily in its ability to bind toxins and pollutants and to purify the air. Peat, wood, lignite, anthracite and coconut shells are required for its production.
How often do I need to change the activated charcoal filter?
The frequency with which the activated charcoal filter in cooker bonnets needs to be changed depends on how often it is used. It is recommended to change the filter once or twice a year, depending on how often you use the bonnet. Activated charcoal filters can be ordered in the air-care.ch online shop.
For instructions on how to change the filter, we recommend consulting the instructions for use or using the manufacturer's online instructions search. Metal grease filters can simply be cleaned in the dishwasher, whereas most activated charcoal filters need to be replaced completely. The so-called "LongLife filters" or regenerable filters are an exception. These can be regenerated by cleaning and then "baking out" in the oven.Our friendly customer service team will be happy to provide you with further information on cleaning extractor hood filters. Please note that the exact frequency of filter replacement may vary from person to person.
How do I replace the activated charcoal filter correctly?
Here is a step-by-step guide to correctly replacing the activated charcoal filter in an extractor hood:
- Switch off the cooker bonnet and wait until it cools down completely
- Open the bonnet and remove the grease filter (if present) according to the instructions in the user manual or by removing it from the holder.
- Locate the activated charcoal filter inside the bonnet. Depending on the model, it may be located in different places, such as behind a cover or in a separate housing.
- Open the cover or housing to gain access to the activated charcoal filter
- Carefully remove the old activated charcoal filter by taking it out of its holder.
- Dispose of the old filter according to local regulations for the disposal of filters.
- Remove the new activated charcoal filter from the packaging and insert it into the holder. Ensure that it is correctly positioned and securely fastened.
- Close the cover or housing of the filter.
- Put the grease filter (if present) back into the bonnet and close the bonnet.
- Switch the cooker bonnet back on and check that the new activated charcoal filter is correctly installed and that the bonnet is working properly.
Please note that this is a general guide and the exact steps may vary depending on the model and manufacturer. It is recommended to always follow the specific instructions in the user manual of your cooker bonnet.
What distinguishes the activated charcoal filter from the metal or grease filter?
Activated charcoal filters and grease filters are important components of extractor bonnets that each fulfil different functions.
Grease filters are used to capture grease and oil vapours from the air that are produced during cooking. They are usually made of metal and can either be cleaned or replaced.
Activated charcoal filters, on the other hand, are special filters that effectively absorb and neutralise odours and vapours. They consist of activated carbon particles that bind odour molecules. Activated charcoal filters need to be replaced regularly as they become saturated over time and lose their effectiveness.Both filters are important for cleaning the air in the kitchen and thus ensuring a pleasant indoor climate.
How do I regenerate a LongLife activated charcoal filter?
Unlike a standard carbon filter, a LongLife filter can be cleaned and reused, which is good for both your wallet and the environment.
It is recommended to clean the filter every 2-3 months, depending on the use of the cooker bonnet, as it loses its effectiveness when saturated with carbon particles. The filter can be cleaned in the dishwasher at a high temperature, carefully knocked out and then dried in the oven at 80°C for around 10 minutes. It is important to clean the filter in an empty dishwasher without dishes to avoid food residues.
Please also follow the instructions of the respective manufacturer, as there may be individual differences.
