This topic is about the ongoing issue of leaks and odors from ostomy-bag filters, which many users find frustrating. Despite trying various brands and models, the problem persists, especially at night, leading to frequent laundry. Users are questioning why manufacturers haven't fixed this issue and why they have to resort to makeshift solutions like using tape.

Here are some helpful suggestions and insights:

1. Consider using pouches without filters. Most manufacturers offer these, although they might be hard to find in catalogs.

2. Coloplast users have reported success with their 1-piece and 2-piece pouches, which have an internal plastic shield over the charcoal filter to prevent leaks.

3. Hollister offers:
- Bag 18182, a drainable pouch with a charcoal filter, known for its long-term leak-free performance.
- The 1-piece soft-convex line, which only comes with a filter. Users often cover the filter with waterproof tape or use the blue filter stickers provided in the box.

4. Convatec Esteem Body, with its new gray, figure-eight shape, includes an extra internal plastic layer to keep output away from the filter. An early user reported no leaks after two weeks.

5. Understanding the physical principles can help: Filters are micro-porous membranes, and any liquid forced against them under pressure, such as when lying down or with gas buildup, can cause leaks. Keeping the filter dry and unpressurized is crucial.

6. For unavoidable filters, try these work-arounds:
- Use factory-supplied filter stickers or waterproof medical tape before the output reaches the filter.
- A hot-glue gun can be used to permanently seal the filter, as demonstrated on the YouTube channel "Let’s Talk IBD."

7. If you need some air in the pouch to prevent pancaking, which is common with colostomies, use a filter-less drainable bag and manually "burp" it when gas builds up.

8. Managing your diet to minimize gas-producing foods can help reduce internal pressure. Manually venting or "burping" the pouch may also be necessary.

9. It's generally agreed that filter performance can vary widely depending on the brand, lot, and individual circumstances. Trying different manufacturers like Coloplast, Hollister, Convatec, and others is often the best way to find a reliable solution.
