They were a lot cheaper than B&D replacement filters. They work the same way and are easy to clean. I use my vacuum cleaner every day and I'm glad I have one. These filters work great. As a side note, I am disappointed that the vacuum cleaner itself is now 40% more expensive than a few months ago as I would happily buy my daughter another one. They soared everywhere, not just in Revane. It's a bit like extrusion. If money isn't an issue, you can buy a handheld vacuum, but I suspect they'll get cheaper again once the supply chain is allowed to expand.
