Triple-Layer Purification Technology

Each filter features a three-stage purification system designed to deliver noticeably cleaner, better-tasting water:

• Cotton Layer: Traps hair, fur, and larger debris before they reach deeper filter stages.
• Activated Carbon & Coconut Shell Layer: Absorbs odors and improves water taste, leaving water fresh and appealing for your pet.
• Ion-Exchange Resin with ABS Grid: Reduces calcium and magnesium buildup, softening water for a healthier drinking experience.

Key Features
