This discussion is about the experiences people have had with filtered versus non-filtered ostomy pouches, particularly in relation to leaks, humidity issues, and pancaking. A concerned spouse is seeking advice because her husband has been experiencing more leaks recently, and she wonders if the high humidity could be a factor. She also appreciates a previous tip about using mineral oil to help with pancaking.

Here are some insights and advice shared by others:

1. Filter performance and pancaking:
- Some people notice more pancaking with new filtered pouches, but this decreases once the filter clogs.
- A couple of users found that the filter on their pouches clogged quickly, causing a vacuum effect, so they switched to non-filtered bags.
- One person successfully uses filtered bags and covers the filter during showers, planning to try a different brand's filter soon.

2. Choosing between filtered and non-filtered pouches:
- If pancaking is a major concern, consider using non-filtered pouches or letting the filter clog naturally.
- Keeping a small amount of air in the pouch can help the output move away from the stoma.

3. Humidity and leaks:
- High heat and humidity alone don't necessarily cause leaks. Some people in hot climates who sweat a lot haven't noticed additional problems.

4. Application technique and routine checks:
- Leaks can often be due to rushing the application process. Make sure the skin is completely dry, use the same mild soap (or none), and take your time to ensure a snug fit.
- Check for any subtle changes in products or routines, like soap, barrier rings, or wafers, that might have started around the time the leaks began.

5. Preventing and managing pancaking:
- Continue using mineral oil or baby oil inside the pouch to help the output slide down.
- Empty the pouch as soon as pancaking starts, even if there's only a small amount of stool, to prevent build-up and leaks.
