Designed for Kärcher NT 35/1 and NT 361 series wet and dry vacuum cleaners, these M Class fleece filter dust bags provide reliable dust containment for demanding trade environments. Supplied in a pack of five, they are an essential consumable for keeping your vacuum performing efficiently on site. Rated to dust class M under BIA classification (covering dust classes U, S, G and C), these bags are suitable for capturing medium-hazard dusts including wood dust, concrete dust, and similar particulates commonly encountered in construction and joinery work. This makes them a practical choice for carpenters, groundworkers, and general contractors who need to meet COSHH compliance requirements on site.
