Originally posted by rburgoss Better to get a large foam sponge from any supermarket and cut thin slices (about 1/4th inch thick) from it and about the size of your filter's hard case. It will not only keep filters from rattling and shaking, but will also stay in place always. A piece of cloth (any kind) will most likely get out of place easily.
Good point. I was thinking about damage to the filter coatings. Will a sponge scratch them? Assuming I can hold it in place OK, what about a microfiber rag (I have a monitor cleaning kit that came with a microfiber cloth that sure seems a lot like the cloths my FW uses for dusting).

I guess I'm not sure how to respond to this one... like rburgoss suggests, I don't like the rattle, and I also worry about the filter being damaged if it isn't held in place.
