Genuine replacement filter cartridge for Arctic Spas - Silver Sentinel Filter

This high efficiency pleated cartridge restores filtration performance and improves water clarity in compatible Arctic Spas hot tub filtration systems. The durable synthetic media traps fine debris and helps reduce maintenance frequency while maintaining proper water flow.

The Silver Sentinel Filter Drop In delivers superior filtration for Arctic Spas manufactured between 1998 and 2008 (excluding Marmot models). Unlike standard cartridge filters that only capture surface particles, this filter features dense media that traps contaminants throughout its depth, achieving 1-micron filtration versus the typical 20-micron standard. Designed for hassle-free operation, simply install and replace every three months—no cleaning or maintenance required. When spent, filters are fully recyclable, making this an eco-conscious choice for spa owners seeking reliable water clarity and quality.
