This topic is about choosing between filtered and non-filtered ostomy pouches, specifically from Coloplast and Hollister, and offers tips for dealing with common issues like pancaking and emptying the pouch without making a mess. Here are some helpful insights and advice:

1. If you prefer a pouch without a filter, the Coloplast SenSura Mio Convex Flip is available in a transparent, filter-less version.

2. For those who like using a filter, Coloplast offers 2-piece closed-end bags with a charcoal filter. These are particularly effective for colostomates since the thicker output usually doesn't clog the filter. It's recommended to dispose of the bag 1 to 3 times a day to keep the filter working well.

3. When deciding between open-ended and closed-end pouches:
- Closed-end bags can be easier to manage, especially if you have dexterity issues or neuropathy, as they eliminate the need to empty the pouch.
- If you decide to try open-ended pouches again, many users find that Coloplast’s outlet is easier to handle than Hollister’s. A tip for keeping things clean is to fold the tail in the middle before re-sealing, which helps prevent smearing.

4. To prevent pancaking:
- Consider using Coloplast Brava Lubricating Deodorant in liquid sachet form. It helps reduce odor and is designed to assist stool in sliding to the bottom of the pouch.
- Try to maintain a small pocket of air around the stoma, rather than at the bottom of the pouch, to help the output fall away from the wafer instead of sticking to it.

5. A general tip is to test multiple brands and lines. Some people find it helpful to try products from all major manufacturers to discover which system best suits their output thickness, dexterity, and lifestyle. You can donate any unused products that don't work for you.
