Zehnder MVHR Filters – Premium Filters for Optimal Indoor Air Quality

Zehnder filters are designed for one of the most popular MVHR units in Europe – Zehnder rekuperators. In this category, you will find filters for various models, including ComfoAir (Zehnder Q350 filters), ComfoD, and ComfoSpot. It is essential to check the model of your unit before selecting a filter for your home or office.

Zehnder recommends the use of G4+F7 filters for optimal performance. You can choose between original filters or alternative options according to your needs. Additionally, you can select from two filter sets or buy individual filters separately. The two-filter sets include either two G4 filters or one G4 and one F7 filter. You can also purchase these filters individually if needed.

Do Zehnder MVHR Units Require Different Filters for Supply and Extracted Air?

In our range, you will find sets with filters that are the same for both supply and extract air, as well as those where the filter for supply air is of a higher class. This is because the air supplied from outside is generally more polluted than the air extracted from your indoor environment. Outdoor air typically contains higher levels of pollutants such as dust, exhaust fumes, pollen, and particulate matter. Therefore, it is crucial to properly filter this air before it enters your living or working space. This filter distribution is also recommended by the manufacturer of the rekuperators themselves.

The Price of Clean Air

If you find it difficult to decide between different filter options, here is a more detailed explanation:

The G4 filter captures the main air pollutants, such as dust, some pollen, fluff, and insects. On the other hand, the F7 filter not only cleans the air from these pollutants but also traps allergens.

If you have children, or individuals suffering from allergies or asthma, or if your home or workplace is in an area with heavy pollution, such as near busy streets, factories, or during the heating season with widespread solid fuel burning, the Zehnder G4 and F7 filter set is undoubtedly the best choice. This combination ensures the highest level of air cleanliness in the spaces where you breathe.

The G4+G4 set is a more economical option, as these filters are less expensive, and the rekuperator consumes less electricity. This is because when air is passed through an F7 filter, it creates higher air resistance, requiring more energy to supply air to the space.
