Profissimo hoover bags feature dust control technology. This is a unique filter system that ensures optimum distribution of the vacuumed dust in the bag and therefore maximum suction power. Anti-allergen through fine dust filtration: The OxiClean Plus filter material consists of a tear-resistant 5-layer special fleece that also filters problematic fine dust such as mould spores, pollen and mite droppings. The Profissimo hoover bags are equipped with OxiFresh technology, which significantly reduces bad odours in the hoover bag. Packaging contains at least 70% recycled content.
