Probably not. But I didn't even know about
pouch filters when I had an ileostomy, so...
The only thing I can say is, if that your stoma is permanent, there should be a lot less gas after a year or so. In the first year after my surgery, I would usually have to get up once in the middle of the night to empty the bag; I would also wake up with a massively distended bag. At some point I realised not only was I not needing to get up in the night anymore, the bag was only half full when I woke up.
It takes a long time for the bowels to reach optimum functioning after bowel surgery - 1-2 years, going from what I've read and my own experience.
