They fit a little but work well and are a lot cheaper than direct from Black+Decker. I was about to throw out my old handheld vacuum, assuming it was going to die. It turned out that while the filter was kept clean, it was just old and worn and restricting airflow. These filters work perfectly. I've been looking for filters by vacuum cleaner model number for a long time but to no avail. Mine was never in the list of models that the filter fits. The key is to search the internet for your model number and get the appropriate filter number first.
