Everything you need to make the call - who each one is for, and who should skip it.
Go for it if you...
You need the strongest formal NSF/IAPMO certification breadth — covering PFAS (P473), lead (NSF 53), RO comprehensive (NSF 58), and emerging contaminants (NSF 401) simultaneously.
Your water has documented PFAS, arsenic, nitrate, fluoride, or multi-contaminant issues that carbon-only filters cannot address.
You prefer a plug-and-play electric system with no filter priming or gravity-wait time.
You're on a tight per-gallon budget — AquaTru Classic at $465/gallon is the lowest cost of ownership in the seed set.
You want AquaTru's 5-standard NSF certification plus glass storage for filtered water — eliminating plastic contact in the reservoir.
Your household has concern about bisphenol exposure from plastic water storage vessels, even BPA/BPS-free Tritan.
You prefer the aesthetic and inertness of glass for daily drinking water.
The main thing to know
AquaTru Classic ranks first in this category by holding the most comprehensive NSF certification pedigree in the countertop water filter market — five NSF/ANSI standards covering PFAS, lead, emerging contaminants, and RO comprehensive. The demineralization trade-off (pH ~6.5, mineral loss) and Tritan plastic reservoir are the genuine considerations. For verified safety from a countertop filter, no product in this set matches the breadth of AquaTru's certification evidence.
AquaTru Carafe ranks second — closely trailing the Classic at 8.96 vs 9.04 — primarily because Carafe-specific Tap Score lab verification has not yet been published. The glass carafe adds meaningful bisphenol risk reduction for stored water versus the Classic's Tritan reservoir. Functionally identical filtration performance. Choose Carafe if glass storage matters; choose Classic if per-gallon cost is the priority.
Skip this if you...
Mineral content matters to your household — RO removes calcium and magnesium; the $30 add-on restores them but adds cost.
You prefer zero plastic contact for stored water — consider the AquaTru Carafe glass variant instead.
Water waste is a concern — 3:1 waste ratio means 3 gallons flushed per gallon of clean water.
Per-gallon cost is a priority — Classic is $0.11/gal vs Carafe's $0.19/gal.
You want existing published Tap Score verification specific to the Carafe SKU — the Classic's data is not yet formally extended to the Carafe.
Heavy lifting is a concern — glass carafe is heavier than the Tritan equivalent.
Neither of these quite what you're looking for?

Straight answers - no sponsored content, no filler.
Both scored close to 9.0/10, so the better choice depends on your priorities. Safety is our top-weighted scoring pillar, followed by efficacy, and usability. Check which pillar matters most to your family and compare those specific scores.
R3 uses a deterministic scoring system - the same inputs always produce the same score. We evaluate each Countertop Water Filter across Safety, Efficacy, Usability using independently verified data. No sponsored rankings. No paid placements. Every score is fully reproducible.
Not necessarily. The overall score reflects how we weight those three pillars, but your priorities may differ. If you care most about safety, compare the safety scores directly. If budget drives your decision, the prices tell a clearer story. The "right" pick is the one that matches what matters most to your family.
