About this item
- SGS-Tested Lead Removal: The media of FC25B-PB filter is rigorously tested by SGS, effectively removing up to 99% of lead from your water, ensuring safer drinking water for your household.
- Comprehensive Heavy Metal Filtration: Featuring advanced MetSorb media, our FC25B-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.
- Advanced CTO Filtration: The second-stage CTO filter is designed for precision, effectively eliminating residual chlorine, fine impurities, and lingering odors. This step enhances the overall taste and clarity of your water, delivering pure, crystal-clear results.
- Standard Size: Our filters fit standard 20” 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 100,000 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 right away, and we’ll be glad to 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.
