The good thing about the GP fluff is that it is easy to rinse out and pat dry on a paper towel before reusing it. I still happen to have enough Sera filter material to last someone for their lifetime and maybe another half of another life lol. If anyone wants some let me know and I'll send it out. I think I will only use it for emergencies if I run out of GP fluff. I will warn you though that it is crap compared to how easy it is to work with the GP fluff.
