This F7 air filter was specially designed for the Wolf CWL 300/400 Excellent ventilation unit. With a filter class of F7, the filter has the ability to filter out up to 70% of particles, ensuring excellent air quality for the indoor spaces of your home or office.

The effective filtering performance is a major advantage of this filter. Thanks to the fine pleating of the MiniPleat filter medium produced in Germany, it is possible to effectively separate fine dust, bacteria, and pollen, benefiting not only allergy sufferers. The low pressure drop of this filter reduces the power consumption of the heat recovery unit.

The filter has dimensions of 523 x 184 x 25 mm and fits perfectly into the Wolf CWL 300/400 Excellent ventilation unit. Furthermore, the filter has a robust synthetic frame that is both moisture-resistant and mold-resistant, extending its lifespan and minimizing wear and tear.

Please note that this filter should only be used once and should not be cleaned with water or chemical cleaning agents. It is recommended to replace the filter 2-3 times a year, depending on air quality. The exact intervals can be found in the ventilation system's user manual.

Your order includes one air filter. The SKU of the item is SFISUN523X184X25E. It is important to note that the color of the filter may differ from the item image.
