The topic at hand is about finding ways to prevent night-time leaks in Convatec Natura filtered pouches. These pouches are favored for their excellent fit and seal, but they have a tendency to leak through the filter during sleep. Here are some insights and advice to help manage this issue:

1. The stick-on filter covers that come with the pouches don't effectively stop night-time seepage.

2. Switching to a different brand isn't an option because the Natura line is the only one that offers the necessary moldable flange.

3. The filter's proximity to the stoma might be causing it to get wet quickly, leading to leaks.

4. A potential redesign idea includes a hinged plastic cap with absorbent material to protect the filter.

5. The user is looking for practical solutions to continue using the same pouch while eliminating night leaks.

Additional insights and advice include:

- Thicken the effluent sooner:
- Use Convatec gel sachets or request free samples from their customer service.
- Try Ilio Gel by adding two packets per bag as an alternative thickener.

- Physically block the filter opening:
- Cover the filter with Scotch tape or waterproof medical tape after showering or before bed to minimize seep-through.

- Use a liner or internal barrier:
- Modify a Colomajic liner by cutting off the sealed end and inserting it into a drainable pouch to shield the filter.
- Experiment with gluing a small plastic flap inside the pouch to deflect output away from the filter.

- Consider switching to a non-filtered or different manufacturer's pouch:
- Convatec can exchange filtered Natura pouches for non-filtered ones upon request.
- Some users have switched to non-filtered bags and prefer them due to no leaks and no water ingress while showering.
- Hollister two-piece systems place the filter higher on the pouch, which may prevent this issue.

- Accessories that may help:
- A Salts stoma collar can form a raised barrier to keep output from reaching the filter, though it may cause irritation for some.

- Odor considerations:
- Filters contain activated carbon, so covering them with tape or using a non-filtered pouch might require alternative odor-control measures. However, many users report no extra odor when taping or eliminating the filter.

- Ongoing manufacturer involvement:
- Convatec customer service is open to feedback and has requested used leaky pouches for engineering analysis. They also offer product exchanges free of charge.
