Topic Explanation:
The discussion revolves around issues experienced with Convatec closed end filter bags used for colostomy care. The original poster mentions that their husband switched from Hollister to Convatec due to flange leakage but is now facing leakage through the filter of the Convatec bags. Despite attempts to resolve the issue with replacement bags and using stickers or duct tape over the filter, the problem persists. The poster is seeking advice from others who might have encountered similar issues and any potential solutions to prevent the bag from leaking.

Advice and Helpful Insights:
1. Exploring Other Brands and Products:
- Consider trying different brands such as Coloplast, which might have a better filter placement relative to the stoma position.
- Look into using flushable liners from Coloplast, which can help manage leakage and odor effectively.
- Some users have switched back to Hollister products or tried different wafers within the same brand to find a better fit and prevent leaks.

2. Dietary Adjustments:
- Adjusting the diet to control the consistency of the stool can be beneficial. Suggestions include adding bran or Metamucil to thicken the stool, or incorporating boiled rice into meals.
- Avoiding foods that cause excessive gas and monitoring overall food intake can also help manage bag performance.

3. Bag Management Techniques:
- Try folding the corner of the bag over where the filter is located or positioning the bag at an angle so the filter is at the top.
- Limit the consumption of carbonated beverages as they can increase gas production.
- Consider the practice of irrigation if suitable, as it can help keep the bag empty and prevent leaks.

4. Alternative Solutions to Manage Filters:
- Using a non-vented pouch or an external vent like Ostovent can help manage gas without relying on the built-in filter.
- Covering the filter with a cosmetic cotton pad has been a successful temporary fix for some users to prevent leaks.
- Regularly wiping off the filter if it gets wet with stool to maintain its effectiveness.

5. General Care and Maintenance:
- Ensure that any tape used does not irritate the skin or cause additional issues like excoriation.
- Regularly check and possibly replace the pouch more frequently if odors or leakage are noticed after a couple of days as suggested by some manufacturers.
