Humidifier Levoit Classic 300S Gray — Ultrasonic, 6 L Capacity, Smart Features

Levoit Classic 300S Gray is an ultrasonic humidifier with a 6 L water tank designed for continuous indoor humidification. It generates a fine, cool mist to maintain comfortable relative humidity levels in bedrooms, living rooms and offices. The unit combines adjustable output settings with smart controls for scheduling and remote operation, offering quiet performance suitable for night-time use and prolonged operation without frequent refills.

A large 6 L tank extends runtime, lowering the need for frequent refills. Integrated smart features enable remote control, timers and automatic scheduling through a companion app or voice assistants, providing flexible management of humidification. The neutral gray finish fits common interior styles and the user-oriented design simplifies maintenance and filter access.

How to use

Fill the removable 6 L tank with clean, cool water and securely place it on the base.

When the unit indicates a low water level, power off and refill the tank before resuming operation. Regularly clean the water tank and base according to the manufacturer's maintenance guidance to prevent mineral buildup and maintain hygienic operation.

Usage recommendations

Use distilled or demineralized water to reduce mineral deposits and white dust. Place the humidifier on a stable, level surface at least a few decimetres from walls and electronics. Monitor indoor humidity with a hygrometer and keep relative humidity between 40% and 60% to balance comfort and mold prevention. Follow routine cleaning and descaling to ensure efficient and safe operation.
