iSpring US21B Heavy Duty 2-Stage Undersink Water Filtration System with 10” x 4.5” GAC+KDF and CTO Carbon Block Filters, 1” Ports

  • [Heavy Duty Water Filter System] Made of quality material for all components and equipped with 10” x 4.5” filters, this heavy duty undercounter water filter system is designed to provide you and your loved ones with a continuous on-demand supply of refreshing water whenever your kitchen faucet is on. No waste water. No tank taking up your under sink space.
  • [10"x4.5" Filters] 1st stage KDF plus GAC carbon filter(FG15B-KS) and 2nd stage CTO carbon block filter(FC15B) can remove up to 99% of contaminants, including chlorine, lead, mercury, and many other heavy metals. They also tackle problems like turbidity, cloudiness, colors, bad taste, and odors(e.g. hydrogen sulfide that smells like rotten eggs). A true shield that protects you and your family from ingesting harmful chemicals or contaminants in your tap water.
  • [Steady Water Flow] Thanks to the system’s connection design and its 1” inlet and outlet ports, you will experience less waiting time when filling up your glasses, pitcher, coffee pot, or cooking pots as the peak water flow rate is up to 15 GPM. Based on the contaminant levels in source water and your water use, we suggest that you change your filters every 6-12 months for ideal filtration performance.
  • [Easy DIY Installation] Comes with two 24-inch DIRECT CONNECT hoses that connect the system to the existing under sink incoming water supply and the cold water line of your kitchen faucet. Unlike reverse osmosis systems, you don’t need to spend time drilling a hole on your countertop for a RO faucet. Tool free. No mess. System installation and filter cartridge replacement are a breeze!
  • [TDS Note] Please be noted that the system is NOT designed to reduce Total Dissolved Solids(TDS) removal and instead keeps essential minerals in your water. If you are interested in a filter that significantly reduces TDS, please consider our iSpring Reverse Osmosis (RO) systems RCC7 series or tankless RO500.

    • Q: With this 2-stage undersink water filtration system, do I still need to install a water softener if my water is very hard?

      A: Yes, a water softener is needed if your source water has a high level of hardness, usually with TDS higher than 700 PPM. Hard water can reduce the lifespan of water filter cartridges. The harder the water, the greater amount of scale buildup occurs, and the sooner the filters get clogged.

      This powerful undersink water filtration system can remove up to 99% of sediment, chlorine, rust, pesticides, herbicides, industrial solvents, organic compounds, and various other contaminants that a regular water softener can't, although it does not soften your water. It is recommended that you add a Point-of-Entry(POE) water softener before this Point-of-Use(POU) undersink water filtration system US21B to achieve optimal performance if you have very hard water.
