## What reviewers say

Only one whitelisted tester yielded a readable, hands-on review: Wirecutter names the Classic 300S its humidifier runner-up, calling it nearly as powerful and reliable as its Levoit LV600S top pick with a handy night-light, but flags an unintuitive icon-only interface, tricky cleaning, and reports of tank leaks. RTINGS (paywalled) and TechGearLab (site maintenance) were unreadable and discarded. (Based on 1 review, 1 lab-tested, 2026-02-19.)

Praised: Nearly as powerful and reliable as Wirecutter's top-pick LV600S, and similarly avoids over-humidifying the room; Pleasant built-in night-light that is easy to turn off without stopping humidification; Same smart-home features and same two-year warranty as the top pick.
Flagged: Icon-only onboard buttons are less intuitive and harder to navigate than the top pick's labeled buttons; Reports of the tank leaking after a few months of use (Amazon reviewers and Wirecutter staffers); Harder to clean than the top pick due to the awkward water-vapor chimney and complex basin water channel; Ultrasonic design requires distilled or demineralized water to avoid chalky white mineral dust.
Disagreement: Single readable source, so no cross-tester comparison is possible. RTINGS is paywalled/JS-only and TechGearLab was down for planned site maintenance, so both were discarded and Wirecutter's verdict stands unchallenged here.
