With the innovative activated carbon supply air filter F7 Lite for the ventilation units Stiebel-Eltron LWZ 304 and LWZ 404, you are setting new standards in air purity. This specially developed filter is designed for spaces and environments where air quality is not always optimal. It impresses with its impressive efficiency, filtering up to 65% of fine dust as well as smoke, odors, and various other pollutants from the air.

Perhaps you are familiar with the problem that your heat recovery unit sucks in smoke from the neighbor's chimney, prompting you to turn off the device more often. In such cases, this activated carbon filter comes in handy. Thanks to the high-quality MiniPleat filter medium, which is manufactured in Germany, the activated carbon contained reliably binds unwanted particles, solvent particles, and exhaust pollutants. The result? Noticeably better supply air quality, especially in areas burdened by smog or other air pollution, particularly during the heating season.

But what makes this filter so special? In addition to its ability to separate fine dust, bacteria, pollen, soot, and tobacco smoke, it stands out primarily for its high absorption capacity. This is due to the fact that it contains a significantly larger amount of activated carbon than conventional carbon filters. Furthermore, the moisture-resistant and mold-resistant synthetic frame guarantees high stability and durability of the product.

With a size of 372x184x24 mm, the filter fits perfectly into the mentioned ventilation units and stands out for its extensive filter area, which is significantly larger compared to folded filters of the Z-Line series. As with all high-quality filters of this kind, it should be noted that it cannot be cleaned with water or chemically treated. A regular replacement every 2-3 months depending on air quality is recommended to achieve optimal results at all times.

This is the product from the renowned SafeLuft Aktiv series with the SKU number SFAKUN372X184X24C and the original article number from Stiebel-Eltron 231332. A small side note: The actual appearance of the filter may slightly differ from the one shown in the product image.

Take the opportunity and ensure fresh, clean air in your spaces. RUKATECH - Quality that convinces.
