In the world of ventilation technology, filter class F7 plays a crucial role when it comes to improving indoor air quality. As an integral part of modern ventilation systems, F7 filters make a significant contribution to creating a healthy and pleasant indoor climate.
In this guide we give you a comprehensive overview of filter class F7, its properties, areas of application and its importance for indoor air quality. Our goal is to provide you with the necessary knowledge so that you can make the best possible decision for your ventilation system to ensure an optimal indoor climate.
Filter class F7: A crucial component for clean air
Air filters are indispensable in modern ventilation systems to ensure high air quality and ensure the longevity of the system.
As a rule, ventilation devices contain two types of filters: one filter that protects the heat exchanger from contamination by the incoming fresh air, and a second filter that cleans the exhaust air from the rooms before it passes through the heat exchanger.
The F7 class filter is specifically designed to clean incoming fresh air. This filter class is one of the so-called fine filters and has the task of removing the smallest particles from the air.
The efficiency of an F7 filter is that it can filter up to 80-90% of particles from the air that are smaller than 0.4 microns. These include pollen, dust and other microscopic contaminants.
Why is filter class F7 important?
The quality of the incoming fresh air has a direct influence on the indoor air quality and therefore on your well-being and health. A high-quality F7 filter ensures that the outside air is effectively cleaned of fine dust and allergens. This is particularly important for allergy sufferers and asthmatics, but also generally for a healthy indoor climate.
In addition, an F7 filter effectively protects the heat exchanger of your ventilation system. By filtering fine particles, it prevents dust and dirt from settling in the heat exchanger and negatively affecting its efficiency and service life.
Replacement and maintenance of F7 filters
Regular maintenance and replacement of the F7 filter is essential for consistently high air quality and the protection of your ventilation system. It is generally recommended to change the F7 filter at least once a year, or more often depending on the location and air quality.
A clogged or dirty filter loses its effectiveness and can restrict airflow, which in turn increases energy consumption and reduces system efficiency.
Comprehensive protection through filter class F7
The filter class F7 not only offers basic air purification, but also effectively protects against a variety of air contaminants. This includes coarse dust, fine dust and pollen particles, which can be problematic for both human health and the functionality of ventilation devices..
Versatile protection against air pollution
Coarse dust, which arises from construction sites, agriculture or road traffic, for example, can get into indoor spaces without adequate filtering. While coarse dust can be visible to the naked eye, fine dust particles and pollen are often microscopic.
Fine dust is particularly dangerous because it can penetrate deep into the respiratory tract and cause health problems. Pollen, on the other hand, is a big challenge for allergy sufferers. This is where the F7 filter comes into play, efficiently filtering all these particles from the air before they enter the interior.
Improving the air quality in the house
By removing these particles from the supply air, the F7 filter makes a significant contribution to improved air quality. Clean air is essential for a healthy living and working environment.
Especially in urban areas or near industrial facilities, where air quality is often poorer, an F7 filter makes a significant contribution to improving indoor air.
Protection for ventilation devices
In addition to promoting health, the F7 filter also protects the ventilation devices themselves. By filtering out coarse and fine dust, it prevents particles from being deposited inside the device and impairing its function.
This protective function not only extends the service life of the ventilation device, but also ensures consistently high efficiency during operation.

Technical specifications of the F7 fine dust filter
The effectiveness of the F7 filter is based on its advanced technical properties. These specifications guarantee that the filter meets the requirements of modern ventilation systems.
High separation efficiency
The F7 fine dust filter is characterized by a high degree of separation. This means that a significant percentage of air particles passing through the filter are effectively captured. This ensures that the air entering the interior is of a high level of purity.
Material and standards
The fine dust filter is made of a high-quality synthetic material that is manufactured in accordance with the European standard EN 779. This standard ensures that the filter meets the high requirements for air purification and quality. The synthetic material used is not only efficient in filtering particles, but also durable and resistant to various environmental influences.
Use as a first or second filter stage
One of the outstanding features of the F7 filter is its flexibility in use. It can be used as both a first and second filter stage in the supply air or outside air. In the first stage it protects the ventilation device from coarse particles, while in the second stage it removes finer particles from the already pre-filtered air. This versatility makes the F7 filter an optimal choice for a wide variety of ventilation systems and areas of application.
Importance of fine dust filtration for health
Particulate matter in the air, an invisible but significant factor, has a direct impact on human health. Particles of this type are so small that when inhaled they can reach deep into the lungs and cause health problems. Long-term exposure to particulate matter can cause respiratory illnesses, cardiovascular problems and other serious health risks.
F7 filter: Efficient against pollen and fine dust
In this context, filter class F7, often also referred to as pollen filter, plays a crucial role. These filters are specifically designed to remove tiny pollen particles from the air. Especially during the flowering period, when there is more pollen in the air, F7 filters offer effective protection for allergy sufferers and asthmatics. Thanks to their high filter efficiency, they significantly improve indoor air quality and contribute to the health and well-being of room users.
Various areas of application for the F7 filter
The areas of application for F7 filters are diverse and extend across different areas and applications. Their high effectiveness in filtering supply air and exhaust air makes them a universal solution for clean air.
Filtering the supply air
A typical area of application for the F7 filter is the filtering of supply air in public and private rooms. This includes bars, business facilities, residential buildings and private households. In these areas it is important to clean the incoming outside air of pollutants in order to ensure a healthy indoor climate. F7 filters help to remove harmful particles such as fine dust, pollen and other allergens from the supply air before it enters the interior.
As an exhaust air filter in kitchens
In kitchens, especially those with heat recovery systems in the ventilation system, F7 filters are also very important. They clean the exhaust air of grease particles, odors and other contaminants. This not only contributes to better air quality, but also protects the ventilation system components from contamination and sticking, which increases the efficiency and longevity of the system.
Use in areas with high levels of particulate matter
Another important area of application for F7 filters is in regions with high levels of fine dust in the outside air. Urban areas, industrial zones or regions with intensive traffic can have significantly increased levels of particulate matter. Here, F7 filters make a decisive contribution to improving air quality by effectively filtering fine dust particles from the supply air.
Consideration of installation options
However, it should be noted that not all ventilation installations allow the installation of a particle or pollen filter such as the F7. Before considering a filter upgrade, it should therefore be checked whether the existing system allows the installation of such a filter. Not only the size and type of filter, but also the specific requirements of the ventilation system play a role here.
Placement of the filter by suction side
An important aspect when installing air filters is the side from which fresh air is drawn in. This determines where the higher class filter, such as the F7, is used. The F7 filter is typically installed where outside air enters the system to ensure the highest possible purity of supply air. On the other hand, typically for exhaust air, a different type of filter, such as a G4 filter, is usually used. This type of filter is less fine and primarily serves to protect the system from larger particles.
Identification of the filter class in the product name
When choosing the right filter, it is important to pay attention to the filter class that is specified in the product name. This ensures that the filter meets the specific requirements of the ventilation system. An F7 filter, for example, is significantly more efficient in particle filtration than a G4 filter and is therefore preferable in areas with high levels of particulate matter.
Comparison of filter sizes for correct installation
To ensure correct installation and optimal functionality of the filter, the size of the new filter should be compared to the old filters to be on the safe side. An inappropriate filter size can lead to loss of performance or even damage the system. Therefore, it is advisable to check the exact dimensions of the existing filter and compare them with the specifications of the new filter before purchasing.
