Frequently Asked Questions
Q: Will this filter fit my Hot Springs spa?

Q: What's the difference between C50 and HS50?
A: They're the same filter with different naming conventions. C50 is the cartridge designation, HS50 is the Hot Springs model number - both refer to this exact filter.
Q: How often should I replace this filter?
A: With proper maintenance (weekly rinsing, monthly deep cleaning), expect 12-24 months of service life. Replace sooner if you notice reduced water flow, visible wear, or persistent discolouration after cleaning.
Q: Can I clean and reuse this filter?
A: Yes - this filter is designed to be cleaned and reused multiple times. Use our 1L Filter Cleaner Soak monthly for best results.
Q: How many filters should I buy?
A: We recommend purchasing 2 to rotate between cleaning cycles. This extends the life of both filters and ensures continuous filtration while one is being cleaned and dried.
Q: Do I need tools to install this?
