Key Features

🔹 Multistage Filtration Technology
ROCK’s advanced multistage design combines high-density sediment filtration with an activated coconut-carbon block, effectively reducing chlorine, heavy metals, chemical residues, and fine particles — while preserving the minerals your body needs.

🔹 Certified Safe & Durable
Made from lead-free, BPA-free materials and certified under IAPMO/NSF-equivalent standards for structural integrity and contaminant reduction. The result: healthier, better-tasting water you can trust for your entire family.

🔹 Long-Lasting Performance
Each filter delivers up to 30,000 litres (8,000 gallons) or 12 months of use — giving you peace of mind and less frequent replacements compared to pitcher or faucet filters.

🔹 Effortless Filter Changes
The twist-and-lock design allows quick, tool-free replacement in seconds. Simply twist out the old cartridge and snap in the new one — it’s that easy.

🔹 Compact, High-Flow Design
Engineered for both performance and convenience, the filter maintains a fast, stable flow rate while fitting neatly under any sink setup.
