Our take

Aquasana's AQ-5300+ is the easiest path to NSF P473 certification under the sink without going to reverse osmosis. Three-stage filtration, dedicated faucet, ~600 gallons per filter set (about a year for a household of 2). Holds NSF P473 certification specifically for PFOA + PFOS — that is the regulatory checkbox the average person actually wants. Install is more involved than a pitcher but easier than RO.

Pros

  • NSF/ANSI P473 certified for PFAS
  • Long filter life (~600 gallons)
  • Faucet included, no electricity

Cons

  • Permanent installation
  • Requires room under sink
  • Filter replacements are bundled (3 stages)
