Made of high-strength and environmentally friendly materials that enhance cleaning performance. Good filter material improves the machine's working efficiency and expands the absorption range, helping increase the vacuum cleaner's suction power to capture pet hair, oil residue, fibers, hair, pollen, flying dust, and tiny particles. This makes your cleaning more effective. Activated carbon filter: The back is made of high-quality activated carbon particles derived from coconut shells, which help absorb various odors and oily smells, especially those from household pets, cat litter, and pet mats. It helps clean carpets and filter out grease and odor. Washable and reusable: Installation of the Airclean Plus 50 replacement filters for Miele vacuum cleaners is easy. We recommend washing the filter once a month and replacing the filter every 3 months to keep the inside of the vacuum cleaner clean and dust-free.
