  • Enhanced Filtration Capacity: The US21B-CPB under sink filter system includes 2 filters and features a 4-layer deep filtration process. The 1st stage FG15B-KS effectively reduces PFAS, PFOA/PFOS, chlorine, mercury, cloudiness, colors, bad taste, and many other heavy metals. The 2nd stage FC15B-PB is SGS tested to reduce up to 99% lead from water.

  • 80K High Capacity: With 1” inlet and outlet ports, the system reduces waiting time when filling glasses, coffee pots, or cooking pots. It offers a high capacity of up to 80,000 gallons. For best performance, up to 12 months change filters based on your water's contaminant levels and usage.
  • Effortless DIY Installation: The under sink system includes 2 upgraded 48-inch DIRECT CONNECT hoses that easily link to your existing under-sink water supply and kitchen faucet. Unlike other undersink water filters, this setup requires no countertop drilling or extension hoses. It's tool-free and mess-free, making installation and filter replacement a breeze.
