Activated-carbon-fiber faucet filter for chlorine taste/odor only; 320 gal or 3 months. Replacement WD-FF-01C 3-pack $41.99 (~$14 each; annual cost est.). Not for pull-out, hand-held or sensor faucets. Waterdrop states NSF 42 and 372 certification, but neither the FC-01 nor its filter appears in NSF's Waterdrop listing (nsf.py 'Waterdrop'/'FC-01' 042) or on Waterdrop's own NSF page, so treat as manufacturer-stated. No lead, PFAS, arsenic, uranium, nitrate or fluoride claim on the manufacturer page (the Amazon title's 94.2% chlorine figure is not on Waterdrop's site). Amazon $18.99.
