The iSpring FC15B-PB Replacement Cartridge is your top choice for effective lead removal in your water filtration system. This advanced filter pack begins with a 10-inch high-performance sediment filter that effectively removes sand, silt, dirt, and rust, protecting your plumbing and appliances from potential damage. The second stage reduces arsenic (III & V), mercury, cadmium, and up to 99% of lead, giving you and your family peace of mind with every use. With its high-capacity performance, the WGB21B-CPB consistently delivers a continuous supply of top-quality water, making it ideal for cooking, bathing, and pets, so you can enjoy premium water quality throughout your home.

• Lead Removal: The media of the FC15B-PB filter can effectively remove up to 99% of lead from your water, ensuring safer drinking water for your household.
• Comprehensive Heavy Metal Filtration: Featuring advanced MetSorb media, our FC15B-PB water filter efficiently removes heavy metals like arsenic (III & V), lead, mercury, cadmium, and more. This superior filtration extends the lifespan of the filter, reducing replacement frequency. (Note: This product is independently manufactured by iSpring and is not affiliated with MetSorb.)
• Superior Sediment Filtration: The first stage utilizes a high-performance polypropylene (PP) sediment filter, capturing particles as small as 5 microns. This pre-filtration step not only ensures optimal water quality but also prolongs the life of the subsequent filters by preventing clogs.
• Standard Size: Our filters fit standard 10” x 4.5” housings, including brand-name models.
• Built to Last: Your filter changing schedule will depend on the contamination level of your source water. We recommend changing your filters every 12 months or after filtering up to 50,000 gallons of water.
• Guaranteed Freshness: Each cartridge is individually wrapped to maintain optimal freshness. Please unwrap before use.
• Peace of Mind Support: Register online to activate your warranty and enjoy lifetime free tech support from our U.S.-based team. We stand by our products—if you encounter any issues, contact us immediately, and we’ll gladly assist!
• Important Note: This filter does not reduce Total Dissolved Solids (TDS) like an RO membrane. If TDS removal is your goal, we recommend exploring our iSpring Reverse Osmosis (RO) systems.
