For all those who do not want to compromise on their indoor air quality, we proudly present the F9 replacement filter for the ventilation unit Wolf CWL 300/400 Excellent. This high-performance filter takes your ventilation system to a new level of air purification.

The requirement was clear: a filter that also meets the highest standards of purity and health. The result? A supply air filter that is capable of eliminating an impressive 85% of fine dust. This ensures that you and your family can always breathe fresh and clean air, free from the smallest pollutants that may be present in the indoor air. Especially for allergy sufferers, asthmatics, and families with children, this filter is the first choice. It not only protects against fine dust, but also against pollen, bacteria, soot, and even tobacco smoke.

But not only its filtering performance makes it special. With a synthetic frame that is both moisture-resistant and mold-resistant, this filter guarantees a long service life and stability. The filter medium MiniPleat, manufactured in Germany, offers a significantly larger filter surface area than conventional filters, resulting in low pressure loss and longer service life.

It is important to emphasize that despite its impressive filtration properties, this filter has no negative impact on the performance or energy consumption of your ventilation unit.
Please note that this filter is designed for single use. It cannot be washed or chemically cleaned. A regular replacement every 2-3 months is recommended, depending on the quality of the supply air.

And while we know that it's what's on the inside that counts, we would like to point out that the actual filter color may differ from the product image. Invest in clean air. Invest in your health. Choose the alternative F9 filter for the ventilation unit Wolf CWL 300/400 Excellent.
