This premium F7 filter has been specially designed for the Viessmann Vitovent 300-W ventilation unit (HR A300/400, H32S B300/B400) and allows for efficient fine dust separation of up to 70%.

Thanks to its standard filter class, the F7 filter ensures high air quality in your indoor spaces. To ensure healthier and more pleasant air, fine dust, bacteria, and pollen are safely separated. This filter also offers excellent value for money.

The filter frame is robust, moisture-resistant, and mold-resistant. Compared to pleated filters (Z-Line), the German-made MiniPleat filter medium with fine pleating offers a significantly larger filter surface area. This reduces pressure loss and extends the filter's lifespan.

It is important to note that this alternative replacement filter is intended for one-time use and cannot be rinsed with water or chemically cleaned. It is recommended to replace the filter 2-3 times a year, depending on the supply air quality in your environment. The exact replacement intervals can be found in the manufacturer's information for the ventilation unit.
