About This
- 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.
- Expanded Filtration Surface: Our upgraded under sink water filtration features an expanded filtration surface, allowing for more effective removal of contaminants. This ensures clean & healthy water for your household, enhancing your overall water quality and providing peace of mind.
- 50,000 Gal 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 50,000 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.
- Premium Quality Construction: Made with high-quality materials and premium 10” x 4.5” filters, the iSpring US21B-CPB provides safe, clean water for drinking and cooking straight from your tap. This durable under-sink filter system offers a continuous supply of refreshing filtered water without wasting space or water.
- Reliable Customer Support: We offer tech and customer support via phone and email from Atlanta, GA. Contact our team for product selection and after-sale support to enhance your experience. We're here to help now and in the future. Note: This filter system does NOT reduce Total Dissolved Solids (TDS) but keeps essential minerals in your water.
