Smart humidifier for bedrooms and large rooms

The LEVOIT OasisMist delivers warm and cool mist with a 4.5L top-fill tank and dual 360° nozzles. It covers areas between 215430 ft² and runs as quiet as 26dB. App control and Auto Mode keep humidity between 40 and 60 percent RH automatically. The BPA-free construction suits babies and adults alike.

Replaces manual fill and single-mist units

Upgrade from humidifiers that require flipping tanks or offer only cool mist. The jump is worth it when you want remote scheduling via the VeSync app, warm mist for winter comfort, and aromatherapy pads for essential oils. It solves the hassle of frequent refills and uneven coverage in larger spaces.

Easy top-fill setup with minimal issues

Pour water directly into the top opening without removing the tank. The wide mouth allows simple cleaning with the included brush. Most problems come from skipping regular pad changes or letting mineral build-up block the nozzles. The rectangular shape fits standard surfaces without special mounting.

Questions about this item

What are the exact dimensions of the LEVOIT OasisMist 4.5L humidifier so I can check if it fits my nightstand?

The unit measures 10.8 inches wide, 6 inches deep, and 11.97 inches high, weighing 5.3 pounds, so verify your surface has at least that footprint and clearance.

How do I set up the auto-humidity feature on the LEVOIT OasisMist, and what step do people often miss?

Connect the humidifier to Wi-Fi via the VeSync app, then enable Auto Mode and set your target between 40 and 60 percent RH; the step often missed is completing the app pairing before pressing the physical Auto button.

Which parts of the LEVOIT OasisMist 4.5L will I need to replace over time?

The box includes three aroma pads and three absorption pads with one of each pre-installed; plan to swap these periodically as they wear out or become saturated.
