Maximize the performance of your vacuum cleaner by using official Miele HyClean dustbags, which work in harmony with your cleaner to maximize its efficiency and give you the best possible cleaning results. The dustbags are made from a special kind of fleece that gives you nine layers of filtration designed to capture even the smallest of particles. It's sturdy enough that larger particles won't damage its finer layers, and thanks to its special internal construction, it will perform just as well when nearly full as it will when empty. It has clever internal airflow guides to ensure that the bag is completely filled before being changed, and its automatic hygiene shutter prevents dust and bacteria from escaping when you dispose of it.
