HOTUBJOY Silver Ion Cartridge for Hot Spring Spas – Freshwater Ag+ Mineral Sticks 80010 (formerly 71325) | 16 Months of Crystal-Clear Water

Elevate Your Hot Tub Experience with HOTUBJOY

Transform your spa into a tranquil retreat with water that feels silky and looks crystal-clear. The HOTUBJOY Silver Ion Cartridge uses a precise 1.05% silver ion technology to help maintain clean, inviting water between traditional filter cycles in hot tub systems.

Designed for Freshwater Ag+ Continuous 80010 compatibility (formerly 71325), these mineral sticks slip into your filter standpipe to deliver ongoing water care without overwhelming odors or harsh chemical smells. You’ll notice water that smells fresher and feels gentler on skin, swimwear, and eyes during everyday soaks.

Key Benefits

• Wellness spa benefits daily: the silver ion formulation supports a calm, silky soak with reduced odors.
• Crystal-clear water you can see through: water feels gentle on skin and fabrics with minimal chemical scent.
• Long-lasting care: four mineral sticks provide up to 16 months of water care for many tubs, with less frequent replacements.
• Lower chemical footprint: can reduce traditional chemical use by up to 50%, helping minimize fumes and skin irritation.

Smart Design and Use

• Effortless installation: drop the cartridge into your filter standpipe—no tools or tech knowledge needed.
• Smarter water chemistry: potentially lowers harsh chemical use while maintaining water quality.
• Universal fit: compatible with standard 1.25-inch standpipes; adjustable length from 6.5 to 16 inches for diverse filtration setups.

Note: Not compatible with saltwater systems, Smart IQ systems, or electronic monitoring equipment. This kit is designed for traditional filtration setups and is ideal for standard residential hot tubs of varying sizes. With regular replacement, your spa remains guest-ready and inviting for family and friends.
