The Miele KK Vacuum Cleaner Bags includes 5 vacuum bags and two filters (one pre-motor filter and one Super Air Clean filter). Miele’s revolutionary new dustbags are made of a unique, new material. An intricate web of 3-ply random-spun fibers allow the bag to retain significantly far more tiny particles and allergens than with conventional paper dustbags. The enhanced composition virtually eliminates clogging, improving suction performance even further.
