About This
- Targets Harmful PFAS Chemicals – The FC15B-PF carbon block filter is independently tested to reduce up to 99% of PFAS, including PFOA and PFOS, providing reliable protection from “forever chemicals” commonly found in municipal and well water.
- Chlorine, Taste & Odor Reduction – In addition to PFAS, the carbon filter also reduces chlorine, VOCs, and unpleasant taste and odor, while the sediment filter captures rust, dirt, and sand to protect plumbing.
- High Capacity & Long Lifespan – Each cartridge lasts up to 12 months or treats 50,000 gallons of water, depending on usage and water quality. Fits standard 10” x 4.5” housings in most home water filtration systems.
- Peace of Mind Guaranteed – Backed by a 1-year limited warranty and lifetime technical support from our U.S.-based customer service team. Whether you’re buying your first system or replacing filters, we’re here to help before and after your purchase.
- Please Note – This filter retains healthy minerals and does not reduce TDS. For total dissolved solids removal, pair with an iSpring Reverse Osmosis system—an ideal complement to any whole house water filtration system.
