The Levoit LV600HH is a 6 L hybrid ultrasonic humidifier that can run warm or cool mist, with a built-in humidity sensor and a remote. This page is based on manufacturer-published specifications and manuals plus aggregated owner reviews; we did not test the products ourselves.
Our verdict
If you need to humidify a large living room or open bedroom, or you want warm mist in winter, the LV600HH is the bigger-room Levoit to look at. If you mainly want app control and easy top filling, the Classic 300S is simpler.

What to know before you buy
- Run time: Levoit’s page lists 36 hours in its summary and “up to 50 hours” in a graphic. Plan on the lower figure.
- Power: warm mist uses a heater, so expect higher power use than cool mist.
- Water: ultrasonic mist can leave white dust with hard water.
