My electric broom has a filter that is small and shaped like a hair bun cover, made of filter cloth and secured with sewn in elastic. I could make one, but I don't know where to find the cloth. Any suggestions?
What about a used dryer sheet? Or the "disposeable" cloths that are sold for kitchen work?
Panty Hose "panties" work for filters for Shop Vacs.
How about a used Swiffer-type dusting cloth that you put on the end of a Pledge Grabit type thing. You could wash one after using it and then sew it up, However, it might be that if you get a swiffer pad wet, it will destroy that awesome static cling that keeps dust in. Just shake it out outside and then sew the elastic around one edge.
