This discussion is about finding the best ostomy pouches that offer reliable gas filtration, especially for those dealing with liquid or loose output. The person sharing their experience is using Convatec Durahesive wafers and is satisfied with their wear time but is frustrated with the performance of the Convatec filtered pouches. They are looking for recommendations on better options. Here are some insights and advice shared by others:

- The filters on Convatec pouches often clog, fail to vent properly, or allow a small amount of stool to seep through. This leads to issues like ballooning or waking up at night.

- The Osto-EZ-Vent was tried but didn't work well because the vent hole got blocked by output, and it interfered with the stoma position.

- There is interest in trying Coloplast and Hollister filtered pouches, but there is hesitation to switch due to the excellent seal provided by Durahesive wafers.

- Insurance covers a certain number of closed-end and drainable pouches per month, and there is a preference for changing pouches frequently to start with a fresh filter each time.

- There is a consideration of going back to filter-free pouches and manually "burping" them as a potentially more reliable option.

Here are some recommendations and tips from others:

1. Coloplast SenSura Click (Extended Wear) two-piece:
- The charcoal filter is generally reliable unless it gets wet.
- Tips include changing the pouch daily or every other day, covering the filter during showers or baths, folding the top of the pouch over at night and securing it with bobby pins to keep stool away from the filter, and adding ostomy deodorant for odor control.

2. Coloplast SenSura Mio (grey):
- The filter vents well, but some users report wafer leakage after 2–3 days. Samples are available from Coloplast.

3. Coloplast Assura two-piece:
- Known for better odor elimination compared to Convatec filters.

4. Hollister New Image system:
- Features a membrane filter that lets gas out while blocking liquid. If stool reaches the filter, "squeegee" it downward to resume venting. The Hollister #3344 closed-end pouch offers larger capacity, reducing daily changes.

5. Cymed pouches:
- Filters are covered with Gore-Tex, providing good protection against liquid blockage.

6. Osto-EZ-Vent:
- A self-adhesive manual vent that can be added to any pouch for quick gas release. It's effective and inexpensive, with samples available.

7. Manual alternatives:
- Some users tape over the factory filter and "burp" the pouch manually when needed. Letting air in first can help if the filter blocks due to thick output or vacuum in the bag.

8. General tips:
- Keep filters dry, as they stop working and can wick odor when wet.
- Frequent pouch changes help reset the filter before it clogs.
- Marlen "Gas Relief" pouches were highly reliable but are no longer available, with no direct replacement currently.
