Freshwater Salt System Replacement Cartridges – 3-Pack

Effortless Spa Water Care for a Full Year

The FreshWater Salt System Replacement Cartridges take the guesswork out of hot tub maintenance. Each titanium cartridge electrolyzes salt into a steady, gentle release of chlorine — keeping your spa water clean, clear, and soft without the harsh chemical feel of traditional treatments.

What's Included

• 3 replacement titanium cartridges per pack
• Each cartridge lasts approximately 4 months (one full year per 3-pack)

Key Benefits

• Less Chemical Handling – The system generates chlorine automatically from salt, reducing the need to measure and add chemicals
• Softer, More Natural Water – Reduced chemical load means gentler water on skin and eyes
• Extended Water Life – Keep your spa water fresh longer before needing a full drain and refill
• Simple Replacement – Disposable cartridges swap out easily — no tools required

Compatibility

Designed exclusively for the FreshWater Salt System, compatible with all Utopia® Collection and Paradise® Collection spa models by Hot Spring Spas and Caldera Spas.

How It Works

1. Insert the titanium cartridge into the FreshWater Salt System housing
2. The system electrolyzes salt in the water to continuously produce chlorine
3. Replace cartridge every ~4 months or as indicated by your control panel

Always refer to your spa owner's manual for specific dosing and replacement schedules.
