The quality of the air we breathe plays a crucial role in our health and well-being. For those who don't want to leave anything to chance, we present the alternative F9 Premium supply air filter for the ventilation system Stiebel-Eltron LWZ 5 / LWZ 8.

The development of this filter was guided by one thought: optimal indoor air quality for your home. Thanks to its high filter class F9, this filter can impressively retain 85% of fine dust. This means not only fewer dust particles circulating in your living spaces, but also efficient removal of allergenic particles such as pollen, bacteria, and even soot and tobacco smoke. For allergy sufferers, asthmatics, and families with children, this is a crucial advantage to keep the indoor environment as healthy and clean as possible.

The technology behind this high filtration efficiency? The German-made MiniPleat filter medium. With its fine pleating, it provides a larger filter surface area, ensuring minimal pressure loss. This means that your ventilation system can operate efficiently despite the finer filter, without increasing energy consumption.

But this filter offers more than just outstanding filtration properties. The synthetic frame is not only robust, but also moisture-resistant and mold-resistant. This ensures that your filter will function optimally over an extended period even under demanding conditions. However, it is designed for single use. Depending on the quality of the supply air, we recommend replacing it 2-3 times a year.

The Premium supply air filter for Stiebel-Eltron LWZ 5 / LWZ 8 – your choice for a healthier, more comfortable home. A small note: The actual filter color may differ from the product image. With the "SafeLuft Premium" product line and SKU SFIPUN372X184X24B, you can be sure that you are receiving a product of the highest quality.
