Filters are designed to help reduce odor and gas build-up in ostomy pouches, but for urostomy pouches, filters are less commonly needed because urine output generally does not produce significant gas. In this product range, none of the pouches include a filter, which simplifies the product and focuses on the features most important for urostomy users, such as anti-reflux valves and secure closures. For example, Convatec 401551 and Convatec 401555 both omit filters for this reason. This design choice keeps the pouch lightweight and easy to use, while focusing on the most relevant features for urostomy care.
