Advanced protection from PFAS, fluoride, lead, and micro-contaminants.
Description
The ROCK Ultra Replacement Filter delivers professional-grade purification for those who demand the highest water quality in their home.

Key Features
🔹 Next-Generation Ultrafiltration+ Protection

Constructed from BPA-free, lead-free, food-grade materials for uncompromised safety from the inside out.
🔹 Long-Life Performance
Each cartridge provides up to 30,000 litres (8,000 gallons) or 12 months of protection, ensuring pure, great-tasting water all year round — at a fraction of bottled-water costs.
🔹 Easy, 3-Second Replacement
The twist-and-lock system allows effortless filter swaps with no tools or plumber required.
Simply twist out the old filter, twist in the new one, and enjoy instant refresh.
🔹 High Flow, Compact Design
Engineered for strong, stable flow with a sleek 9 cm profile that fits neatly under any sink — perfect for kitchens, offices, or compact spaces.
