Bedroom humidifier designed to keep air comfortable and easy to manage, with smart control and whisper-quiet operation. The Levoit Smart Cool Mist Humidifier brings scheduled humidity, app and voice control, and near-silent nights to busy households. Is it the right fit for a nursery, a light sleeper, or someone who wants hands-free humidity control?

⚡ At a Glance
  • Humidification Performance: Built-in humidistat with Auto Mode keeps humidity in the 40–50% range, pausing mist above 50%.
  • Best for: Light sleepers, bedrooms and households that want scheduled or remote humidity control.
  • Not ideal for: Large open-plan spaces or whole-house humidification needs.

Auto Mode uses a built-in humidistat to maintain a comfortable humidity band. Near-silent operation and smart controls suit bedroom use.


Effortless remote control - With VeSync app and voice control

VeSync app allows adjustment of humidity levels, custom scheduling and timers from anywhere, and pairs with Alexa and Google Assistant for hands-free commands. App-controlled Auto Mode can be toggled and adjusted remotely.

Schedule the humidifier to start before returning home or set a nightly routine without touching the unit. Voice control makes quick adjustments easy when hands are full.

Stable indoor humidity without fiddling - Thanks to built-in humidistat and Auto Mode

Auto Mode monitors ambient humidity and adjusts mist output to maintain a target range, with a default target of 45% and an operating band of 40–50%. The unit pauses misting when humidity exceeds 50%, and app settings allow manual override.

Rooms stay within a comfortable humidity range with minimal intervention, reducing dryness or over-humidification. Manual mist settings can be used when continuous output is preferred.

Quick refills and easier cleaning - With top-fill 3 litre tank and large opening

Top-fill design permits filling the 3L water tank from above, avoiding tank flipping, and the large opening simplifies access to the interior. Manufacturer guidance recommends cleaning the tank and base compartment every three days and never immersing the base.

Refilling becomes a fast, spill-free job and routine cleaning is simpler, helping maintain performance and prolong service life. Regular cleaning helps prevent build-up and keeps the unit hygienic.
