About this item

• 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.
• Superior GAC KDF Filtration: The 1st-stage FG15B-KS effectively reduces PFAS, PFOA/PFOS, chlorine, mercury, cloudiness, colors, bad taste, and many other heavy metals.
• 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 80,000 gallons of water.
