Clear, clean air is more than just a luxury; it is a necessity for well-being in our residential and work areas. The alternative F7 filter for Stiebel-Eltron LWZ 5 / LWZ 8 understands this need and has been developed to provide you with exactly that.

With its F7 classification, the filter can efficiently retain up to 70% of the incoming fine dust. This results in a noticeably improved supply air quality in your spaces. This is particularly important in urban areas or regions with high pollen concentrations, where air pollution and allergens are more common.

A remarkable feature of this filter is the MiniPleat technology. Unlike conventional filters, it offers a significantly larger filter surface area and reduces pressure loss. This has the dual benefit of increasing the efficiency of air filtration and reducing the power consumption of the heat recovery unit.

The robustness and durability of the filter are ensured by its synthetic, moisture-resistant frame. This not only protects the filter from potential mold formation but also contributes to a longer lifespan. Users therefore benefit not only from clean air but also from a durable product that offers excellent value for money.

Finally, it should be emphasized that the quality of the MiniPleat filter medium used, which is manufactured in Germany, provides additional security for users. The dimensions of 372x184x24 mm also ensure that the filter fits perfectly into your device. With the product line "SafeLuft Standard" and the SKU SFISUN372X184X24B, the ordering and replacement process is also facilitated.

Invest in clean air and enhance your well-being with the supply air filter for Stiebel-Eltron LWZ 5 / LWZ 8.
