Households seeking comprehensive under-sink filtration for city water with PFAS/PFOA/PFOS and heavy-metal reduction, plus convenient DIY installation.
Great Value
Up to 18 months per filter set; 8000 gallons total capacity
Key Buying Points
8-stage deep filtration targets PFAS, PFOA/PFOS, residual chlorine, fluoride, lead and heavy metals for safer, better-tasting water.
NSF/ANSI 42 certified CT filtration improves taste by reducing residual chlorine while preserving beneficial minerals.
Long-life design: up to 18 months of filtration, with total capacity up to 8000 gallons.
Ultra-compact under-sink form factor with DIY install in about 3 minutes and quick 3-second filter replacements.
Push-to-connect fittings and twist-and-lock filter design simplify maintenance and reduce DIY error.
Durable, leak-resistant construction tested to high burst pressures (age-resistant materials minimize cracking/leaks).
Includes under-sink unit, inlet/outlet hoses, adapters, and Teflon tape for a complete install; compatible with standard cold-water lines.
The Catch
Initial water may appear cloudy or milky due to trapped air; run water for several minutes to clear.
Some SKUs may require a dedicated faucet or additional faucet installation; base kit may not include it.
Replacement filters incur ongoing costs; each filter has its own lifespan and may require periodic replacements.
Not a water-softening or reverse-osmosis system; does not reduce Total Dissolved Solids (TDS).
Under-sink installation requires space and plumbing access; may not fit all sink configurations or renters' setups.
