I use the Hollister with filter's and they work great! The only time it puffs up is when there is runny poop blocking the filter. I use "Adapt" lubricating deodorant and it really cuts down on any smell emanating out of the filter. If my pouch does fill, I "burp" it and blame the smell on our Pugs. LOL.
