About This

  • [SGS Tested Bacteria & Virus Removal]: This filter features a high-efficiency filtration membrane and offers superior microbial protection. The FC15-BV water filter has been rigorously tested by SGS and effectively removes viruses, bacteria, colloids, and particulates, ensuring water safety and cleanliness. Its advanced membrane captures even the smallest pathogens, providing robust defense against waterborne illnesses and ensuring cleaner, healthier water for your home.
  • [Patented Design for Easy Installation] - Say goodbye to complicated setups! Unlike other brands that require crawling under the sink and taking up to 30 minutes to install, iSpring’s exclusive top-mount faucet kit features a cutting-edge, tool-free design. With its stand-and-install setup, you can have your system up and running in just 20 seconds - no hassle, no stress.
  • [Advanced Water Filtration for Purity]: The iSpring US31-BV utilizes a robust 3-stage filtration process to provide the cleanest, safest drinking water. The process begins with sediment filtration to remove large particles, followed by CTO filtration to remove chlorine and some organic chemicals. Finally, the specialty CTO filtration layer thoroughly eliminates bacteria, viruses, rust, dirt, taste, and odors, leaving you with crisp, clear water free from contaminants.
  • [Reliable Performance & Superior Craftsmanship]: The iSpring US31-BV offers a high flow rate of up to 1 GPM, surpassing conventional under-sink filtration systems. Perfect for providing pure drinking water, washing fresh produce, and meeting the daily water needs of your entire household. The system is built with precision and high-quality materials. It features an elegant European-style brushed nickel faucet and a transparent first-stage housing for effortless filter monitoring.
  • [Easy Setup and Low Maintenance]: The system is designed for straightforward installation and low maintenance. No plumber is needed. This under-sink water filter is a simple DIY project. To maintain peak performance, it is recommended to replace the filters every 6 to 12 months, depending on water usage and the quality of the water source.
  • [TDS Retention and Customer Support]: The iSpring US31-BV maintains the total dissolved solids (TDS) levels in your water, preserving important minerals. If you're looking to reduce TDS further, we recommend considering an iSpring reverse osmosis system. Backed by a 1-year warranty and lifetime customer support from Atlanta, GA, the iSpring team is always ready to assist with any questions or concerns.
