About This

  • Replacement Filters: To replace filters for your Ontulor S2OP-U1 under-sink water filtration system, search B0FYDVZ1TH for PP filter, B0FYF5NZJ2 for C1 filter, B0FYF72PK6 for UF filter, and B0FYF6QMZ1 for C2 filter
  • Better Taste Than Bottled Water: Enjoy fresh, clean water right from your tap. This under sink water filtration system preserves essential minerals while reducing harmful contaminants, giving you a crisp, refreshing taste that’s even better than bottled water—without the cost or plastic waste. Perfect for drinking, cooking, and making coffee or tea
  • Quick & Easy Setup: Designed to fit standard 3/8’’ or 1/2’’ water lines. Even if you’re not handy, you can quickly set it up by following the included step-by-step manual and video guide. The under sink water filter system can be mounted on the wall or placed on the floor, so you can choose the setup that works best for your kitchen space
  • Long Filter Lifespan & Smart Monitoring: The built-in filter life display and pressure gauge make system maintenance easy. At a glance, you’ll know when to replace each cartridge and whether your water pressure is within the optimal range. PP and C1 filters last up to 6 months, UF and C2 filters up to 12 months. Only the inner cartridges need replacement, not the stainless steel housing. Plus, this eco-friendly system produces no wastewater and requires no electricity
  • Advanced Ultrafiltration Technology: Features a high-precision 0.01-micron UF membrane combined with premium filter media to effectively reduce chlorine, odors, heavy metals, fluoride, and other common contaminants. Delivers safer, cleaner, and better-tasting water straight from your tap
  • Space-Saving Design: Compact size (16.38’’L × 4.33’’W × 11.93’’H) easily fits under your sink without taking up valuable storage space. Perfect for small kitchens, and since it runs without electricity, you don’t need to worry about power connections
  • Dedicated Faucet: Comes with a lead-free brushed stainless steel faucet for drinking water only. Use your regular kitchen faucet for washing, and the included faucet for pure, filtered water—ensuring both safety and convenience
  • Note: This water filter system does not reduce TDS levels. Instead, it retains beneficial minerals that your body needs while providing clean, great-tasting water
