Review on 👜 Miele 10123230 AirClean 3D Efficiency Dust Bag - Type U (4 Pack) with 2 Air Filters - Green by Jason Cox

Although these 3D Efficiency Packs are marketed as suitable for all U-type cleaners, THEY MUST NOT. I have a Miele 7210 Upright Twist. Pockets are not attached properly and dust is scattered throughout the compartment. Use regular AirClean U filters for S7000-S7999 racks. Miele should stop advertising 3D bags as Type U as there are now two different types of Type U bags (regular and 3D) and 3D does not work properly with all cleaners that state they use Type U. Really disappointing - Miele makes good products and is known for their developments and innovations. Too bad they completely missed the mark with 3D.
