Important: There’s No AquaBliss SF500

- Typo or misremember: People who read about “SF400” or “SF220” occasionally transpose numbers.
- Future model speculation: Forum posts sometimes speculate about upcoming AquaBliss models.
- Third-party listings: Unofficial resellers occasionally mislabel filter accessories or cartridges with model numbers like “compatible with SF500.”
