What the product listing won't tell you
Know before you buy
NSF 42+53 certified for lead, chlorine, and DBPs — solid conventional water protection at the lowest certified per-gallon cost ($0.19/gal). No NSF 401 means PFAS and emerging contaminants are unverified.
Your primary concerns are lead and chlorine/DBP removal and you know PFAS is not a documented issue in your water supply.

You want the longest filter life of any NSF-certified faucet filter (200 gallons — roughly 6 months for a typical family) to reduce replacement hassle.
Per-gallon cost matters and you're comparing NSF-certified options — Culligan FM-15A is 28% cheaper per gallon than PUR Plus.
PFAS, pharmaceuticals, pesticides, or emerging contaminants are a concern — no NSF 401 means these are unverified by any independent body.
You want an electronic filter replacement indicator — Culligan FM-15A has no indicator and requires manual tracking of the 200-gallon schedule.
