About this item

• 1. COMPLETE 3-STAGE FILTER KIT WITH FREE WRENCH: Full matched replacement kit for C11S countertop RO system, including PAC pre-filter with built-in PP cotton pads, premium RO membrane and coconut shell CF post filter. A dedicated filter disassembly wrench is included for tool-free and effortless filter replacement.
• 2. HIERARCHICAL PRECISE FILTRATION: Built-in PP cotton pad inside PAC first traps sediment, rust and large impurities; PAC further blocks coarse contaminants to protect RO membrane; 0.0001μm RO membrane removes ultra-fine dissolved contaminants effectively; CF coconut carbon filter optimizes water taste and eliminates residual chlorine thoroughly.
• 3. UPGRADED RO MEMBRANE ADVANTAGE: RO filtration precision far outperforms common microfiltration and nanofiltration. The independent high-precision RO membrane realizes deep water purification, while front and rear dual carbon filters cooperate to balance filter service life and fresh water flavor perfectly.
• 4. GRADED CLEAR REPLACEMENT CYCLES: PAC pre-filter: replace every 6–8 months; RO membrane: replace every 18–24 months. The overall service life will be shortened in high-sediment and hard water areas.
• 5. EASY RESETTING & RELIABLE AFTER-SALES SUPPORT: Simply reset the filter life indicator after finishing filter replacement with the matched wrench. Our professional customer support team provides timely assistance for all operational issues, ensuring your C11S RO system runs stably and efficiently all the time.
