Glad to hear that the nurse knew her business...makes a world of difference.
I don't like the bags with filters. They don't work IMHO, anyway. The WOCN told me that with an ileostomy you should not use them??? At any rate, I was pancaking with the filters, as they created a vacuum right over my stoma and I was leaking under the wafer.
Since putting the stickers on the filtered bags or using bags without filters I have had better luck. Although, I also changed to convex wafers and whole eakin seals simultaneously.
