This is not a complete solution to the problem of clogged vacuum filters, but it is an improvement. I have a rigid shop vacuum cleaner, it's about 15 years old. It still works well, but for some reason I've only been able to use the filter once in the last few years before having to clean it or change it (it clogs up with fine dirt in the first few minutes of use). use). I suspect this is because I have a dust collection system installed in my shop that leaves nothing but very fine dirt for the vacuum to pick up. The sock also clogs quickly with fine dust, but is MUCH easier to clean. Just shake well over the trash can. So I recommend, but don't expect miracles.
