In the RUKATECH online shop, we strive to offer a variety of products for various needs. The G4 filter mats presented here, specially designed for the ventilation unit Stiebel-Eltron LWZ 304 / LWZ 404, provide a separation rate of up to 65% for coarse dust. This positions them within the lower filter classes used in ventilation systems. While they are not able to effectively remove fine dust, they still provide solid performance in separating coarser particles.

If you are looking for a cost-effective solution, especially for exhaust air filtration, or if you generally have less strict requirements for air purity, then this filter cut could be just right for you. Its construction from a synthetic filter fabric from a leading German manufacturer ensures that you do not have to compromise on quality despite the affordable price. There are also no harmful glass fibers included. Each package contains ten of these convenient filter mats.

Since ventilation systems require constant care and maintenance, this filter is designed for single use and should be replaced regularly accordingly. Depending on the air quality in your environment, we recommend doing this every 2-3 months.

Please note that the actual color of the filter may differ from the color in the product image. With the RUKATECH SafeLuft Lite series, we offer you proven products that convince in terms of efficiency as well as price. This filter cut for the Stiebel-Eltron LWZ 304 / LWZ 404 ventilation units 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).
