My dog is a messy drinker, and these charcoal inserts have genuinely stopped that stale smell from building up between cleanings. Water stays noticeably fresher for the full few weeks, which is exactly what I needed.
These filters are a solid, affordable way to keep the water bowl smelling neutral between full cleanings. They do a decent job with odor control for about two weeks, though I wish they lasted a bit longer before needing a swap.
