The best you can get!
The best vacuum bags you can buy, for the best vacuum we have ever had! Though expensive, these bags not only do a great job at filtering (without excessive air resistance), but also hold a surprising amount of dirt. I was concerned about capacity, as these bags seem small. After examining how dirt is distributed inside (as well as cutting open a full one to retrieve some sucked-up toy parts), it looks like the bag is designed to layer dirt evenly around the outside walls, while leaving an empty space around the center, where the hose end comes in. This not only allows for maximum 'packing' capacity, but also improves airflow. I am totally satisfied with how well these bags work.
