They are easier to wash, the material is stronger and doesn't get soggy with washing. The end caps are also a bit stiffer, but that's a minus as they need to seal the filter in the housing, so a bit of flexibility doesn't hurt. Overall, they are MUCH better than OEM filters. As a bonus, the set of 6 includes a cleaning brush! Recommend them for B&D handheld vacuums that go with them.
