60% more suction power, high filter capacity: The durable synthetic material ensures optimal airflow and high suction power throughout the entire usage period, even as the vacuum bag fills up. It filters up to 99% of all particles - even the smallest particles measuring 1 micrometer (15 times smaller than the diameter of a hair). The air is filtered 40% more efficiently than with paper bags, reliably removing particles such as allergens and certain bacteria from the air. Hygiene closure, easy to change: This vacuum bag with special folding and unique patented cardboard is easy to insert into the vacuum cleaner and is hygienic, as the bag automatically seals upon removal, allowing for quick and clean disposal without spilling the captured dirt. Powerflow™ side folding: The patented 3D side folding ensures the best possible unfolding of the bag in the dust chamber and continues to provide high suction power without clogging the pores, with an additional 15% capacity. Good for the consumer, as the bag only needs to be changed half as often (compared to paper bags).
