Review

What to know about AquaTru Classic Smart

The Wi-Fi/app-connected version of the AquaTru Classic, with the same 4-stage IAPMO-certified RO filtration and 0.75-gallon tank plus filter and usage tracking in the app. BOS Water rated it highest of 18 countertop systems it tested.

Editorial notes

Why it stands out

Why we like it

AquaTru's Classic product page claims IAPMO certification for 84 contaminants, including PFOA and PFOS, and sells the Smart as a variant of that product. The related Classic Connect data sheet lists models AT2000 to AT2050 as certified to NSF/ANSI 42, 53, 58, 372 and 401. On the Classic, Quality Water Lab found all 14 PFAS analytes non-detect. BOS Water rated the Classic Smart highest of 18 countertop systems.

Filters last 24 months or 1,200 gallons and cost about $100 a year. The larger tank means fewer refills than the Carafe.

What to know

Skip it if you want glass-only contact, since the tank is plastic. Check the model number on the box against AquaTru's data sheet before relying on the certification.

Performance

Score breakdown

PFAS reduction evidence

Strength of proof that the system cuts PFAS: a current NSF/ANSI 53/58 PFOA/PFOS or total-PFAS certification (NSF, WQA or IAPMO) and/or independent lab results (TechGearLab/Tap Score, Quality Water Lab). Certified plus lab-verified scores highest; marketing-only claims score lowest.

8.8

Certified via the Classic/Connect data sheets per AquaTru's own page, but the Smart's model number isn't confirmed; independent PFAS non-detect was measured on the Classic.

Other contaminant coverage

Certified or lab-verified reduction of lead, chlorine/chloramine, VOCs, pharmaceuticals (NSF 401), microplastics, and for RO, TDS, fluoride, nitrate and arsenic.

8.6

Same 4-stage certified filtration as the Classic, about 84 contaminants.

Value

Upfront price plus annual filter cost per gallon, judged against the protection delivered.

7.5

$420 on Amazon (Best Buy $525); about $100 a year in filters.

Installation & cabinet fit

DIY difficulty, whether it needs a drilled faucet hole, a drain saddle or an electrical outlet, renter-friendliness, and under-sink footprint (tank vs tankless).

7.5

No plumbing, but the bulkiest certified unit, and the waste tank is emptied by hand.

Flow & daily convenience

Flow rate or production speed, filter-change ease, and filter-life reminders.

7.0

12-cup tank, the largest certified one; a full tank takes about 16 minutes; the app tracks filter life.

Health, materials & sustainability

Lead-free component certification (NSF 372), BPA disclosures, wastewater ratio, energy use, effects on pH and minerals, and any media leaching found in lab tests.

6.5

Tritan BPA/BPS-free plastic tank; BOS measured about 1.6:1 pure-to-drain; auto-flush uses extra water.

Reliability & support

Leak reports, warranty length, availability of replacement parts and filters.

6.0

BOS Water notes complaints about leaks, failures and the app.
