This topic is about the experiences people have with Convatec ostomy bags, specifically focusing on the performance of the integrated charcoal filters. The original poster mentions a 10% failure rate with these bags, which includes issues like loss of filter function, leaks, or odor, and is curious if others have faced similar problems. Here are some insights and advice shared by others:

- Many users find that filters from all brands, including Convatec and Hollister, tend to stop working effectively when the pouch has a moderate amount of output or when the filter gets wet from things like watery output, showering, or nighttime seepage. When this happens, venting stops and odors can develop.

- Some people have decided to stop using bags with filters altogether and have switched to non-filtered bags. They report having fewer issues with odors and fewer failures during the night.

- There are users who still use filtered pouches but choose to cover the filter with the provided blackout sticker. This helps prevent the filter from clogging and avoids the "vacuum" effect, which can cause the front of the pouch to stick to the stoma, leading to pancaking and leaks.

- At least one person mentioned having no issues with Convatec filters and finds them to work well, which shows that experiences can vary from person to person.

- The general agreement among users is that filters, whether from Convatec or other brands like Hollister, tend to lose their effectiveness within a few hours. Their performance is influenced by the consistency of the stool and the moisture levels.
