be possible to just use coffee filters (assuming they are the right size)?

I remember a thread about coffee filters a while ago. I don't remember
the specifics, but I believe someone posted saying that those filters
really didn't work.

Instead go to a fabric store and buy polyfill. Same stuff as in the
fish store. Much cheaper. You can buy it lose and in sheets. Some
posters have reported good sucess useing the sheets as a
prefilter. You want the stuff that has not been treated. Usually it is
the fill that is safe for use in baby pillows and toys.
