Pillow stuffing as filter floss?

[ravio11i]

Works great, i use the stuffing for pillows or homemade stuffed animals or whatever from the craftstore, just shove it in the hob and replace as needed, also built another filter that is just a 2 liter bottle with holes in the bottom, stuffed with fiberfill, and a cheap pump from harbor freight.

I think you have to make sure it doesn't have the fire retardant in it.
