Review on Shop Vac Paper Filter Generic Pack by Mark Taylor

I think it was designed for any size vacuum cleaner. I have a 12 liter vacuum cleaner. The paper filter is at least three inches taller. I suppose it won't matter. Unfortunately, the included rubber strap rotted and broke before it was large enough to bypass the filter. Now I need to find some big rubber bands before I can use my shop vacuum. Must have been sitting somewhere for years.
