Many employees give a building a very lively atmosphere. However, this also leads to more dirt in the house. Even the best and largest vacuum cleaner needs to be emptied at some point. And even though the dust bags are washable, they eventually need to be replaced. These fleece filter bags were designed for the Kärcher T 10/1 Adv dry vacuum cleaner. Thanks to their three layers, they are extremely tear-resistant. These fleece filter bags are developed for dust class M, which means that 99.9 percent of health-threatening dust is filtered out. This way, working with wood, putty, fillers, paints, plaster, cement, concrete, tile adhesive, sand, gravel, as well as latex and oil paints is not associated with health risks.
