If you are looking for the best of the best in the world of ventilation technology, you have come to the right place. Imagine a filter that not only captures fine dust, but even bacteria, pollen, soot, and tobacco smoke reliably. Our new F9 replacement filter for the ventilation system Stiebel-Eltron LWZ 304 / LWZ 404 more than meets this demand.
In a world where the quality of indoor air is becoming increasingly important, this filter offers high safety. Especially for people who value clean air - whether they are allergy sufferers, asthmatics, or parents of young children - this filter is almost indispensable. It carries the highest available filter class for heat recovery units in private households, guaranteeing an unparalleled filtration result.
But this filter sets standards not only in terms of filtration. The German-made MiniPleat filter medium, with its fine pleating, provides a maximum filter surface area, ensuring efficient and energy-saving operation. It's a difference you will feel - in air quality and also on your electricity bill.
Of course, our premium filter also features a stable, moisture-resistant, and mold-resistant synthetic frame. The longevity and high quality of the filter are evident from the first touch. Another quality feature is the significantly larger filter surface area compared to conventional pleated filters.
Since even the best filter doesn't last forever, we recommend replacing it every 2-3 months, depending on the air quality in your environment. This high-quality filter is designed for single use and should not be cleaned with water or chemically treated.
Do not be confused by the product image color: the actual color of the filter may vary. However, what does not vary is the consistently high quality and efficiency of this product from our SafeLuft Premium range. Order today and experience the difference a premium filter can make in your ventilation system.
