At RUKATECH, we know how important it is to find the right filters for your ventilation devices. The M5 filter mat, suitable for the ventilation device Stiebel-Eltron LWZ 304 / LWZ 404, is the ideal choice for those looking for an efficient compromise between filter performance and cost-effectiveness. It can remove up to 50% of medium-sized dust particles from the air. Although this filter is not ideal for completely eliminating fine dust, its efficiency makes it particularly recommended for exhaust air filtration. Owners of ventilation devices with less strict requirements for indoor air quality, focusing on a good price-performance ratio, will also not be disappointed by this product.

Highest quality was ensured in its production. A synthetic filter fabric from a renowned German manufacturer ensures that no health-hazardous glass fibers are present. By ordering this product, you will receive ten of these high-quality filter mats.

Anyone with experience in ventilation systems knows that regular maintenance and care are essential. Therefore, this filter cut is designed for one-time use and should not be cleaned with water or chemically treated in any other way. To ensure a constant air quality, we recommend replacing the filter every 2-3 months, depending on the quality of the incoming air.

Please note that the color of the filter may differ from the color shown in the product image. With the RUKATECH SafeAir Lite series, you are opting for proven quality and efficiency, and this filter cut for the Stiebel-Eltron LWZ 304 / LWZ 404 ventilation devices is no exception.

This filter pad is intended for single use and cannot be rinsed with water or chemically cleaned. An exchange interval of 2-3 times per year is recommended (depending on the quality of the supply air).
