This topic is about a common issue some people experience with Convatec ostomy bags, where the filters seem to leak even when everything is applied correctly. If you're facing this problem, here are some suggestions that might help:

1. Try sealing the filter opening with medical or waterproof tape. This can help prevent any fluid from escaping through the filter.

2. Consider switching to a filter-free Convatec pouch or a similar product from another brand. Many people find that using a bag without a filter can eliminate leakage and odor issues related to faulty filters.

3. If you opt for a bag without a filter, you can manage any excess gas by "burping" the pouch. This means releasing air manually in a private place to keep things comfortable.

4. It's worth noting that filter leakage is a common issue across several brands, not just Convatec, so you're not alone in dealing with this.
