In the RUKATECH online shop, we present a premium solution for your ventilation unit: The supply air filter F9 for Stiebel-Eltron LWZ 170 E Plus / 370 Plus. A filter that convinces not only with its technical data, but also with its quality.

When it comes to indoor air quality, no compromise should be made. For those who set the highest standards and want to protect their family members, especially allergy sufferers, asthmatics, or small children, from harmful particles, this filter is the right choice.

It guarantees that up to 85% of fine dust, including bacteria, pollen, soot, and tobacco smoke, are effectively separated. The F9 filter class represents the top of the available filter classes for heat recovery units in private households.

By using the German-made MiniPleat filter medium with its fine pleating, this filter offers a significantly larger filter surface compared to conventional pleated filters, thus guaranteeing a lower pressure drop. This contributes to a longer filter life and minimally affects the energy consumption of your ventilation unit.

This filter is surrounded by a robust, synthetic frame that is both moisture-resistant and mold-resistant, further increasing its longevity and efficiency. Please note that it is designed for single use and should not be cleaned with water or chemically treated. Depending on the quality of the supply air, we recommend changing the filter 2-3 times a year.

Available as part of the SafeLuft Premium series, this filter has the SKU number SFIPUN523X184X25A and measures 523x184x25 mm. Please note that it is intended exclusively for supply air and the actual filter color may differ from the product image. With an original article number from Stiebel-Eltron, 232477, you can be sure that this filter fits perfectly with your device.
