I've heard of people using 100% polyester batting/stuffing from a craft store, either fluffy or in sheets. It can be rubber banded to the plastic backing of a filter cartridge after your cut off the pre-made floss and remove the carbon. Its a really cheap option. I have not used this myself, but there is much information on dee interwebz you could look up. I'm planning to do this after the floss I'm using presently craps out. Be sure to report back on how your choice works out for ya! Good luck!
Like so, sense of humor required: Very simple and useless Marineland Penguin filter mods.
I use this on my tanks! Works wonderfully and it costs maybe 7$ for a giant bag that will last you a lifetime(not joking).
I use it on my canister filter and hobs
