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.

Tested by Wirecutter
Consistently 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
Commonly 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
Where reviewers disagree 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.
The sources (1)
The Levoit Classic 300S Ultrasonic Smart Humidifier performs nearly as well as our top pick.
But the user interface isn’t quite as intuitive, and we’ve also heard some complaints about the tank leaking when it’s lifted off the basin.
The onboard buttons are more streamlined, but they’re also harder to navigate.
