Levoit Classic 300S 6L Smart Ultrasonic Humidifier, Top Fill Cool Mist for Baby and Plants

Using another type of water such as hard, soft, purified, filtered, or tap water in a humidifier can have some drawbacks (leave behind white dust, unpleasant odors etc.);

It's recommended to use distilled water in our ultrasonic humidifiers. Distilled water has had minerals and impurities removed through distillation, resulting in purer water. Many of our humidifiers also come with built-in filters designed to help reduce impurities. And you can use a different type of water at your own discretion, but distilled water is preferable if possible.

We recommend to empty the water in the water tank daily and before you refill the water.

It's recommended to replace it monthly depending on the quality of water being used. If you notice any discoloration in the filter, please note that it is a part of normal use.

The 300S features Wi-Fi connectivity, app control (VeSync app), voice control with Alexa/Google Assistant, and automatic humidity control (Auto Mode) that maintains your desired humidity level without manual adjustment.

The built-in humidistat continuously monitors room humidity. In Auto Mode, the unit automatically adjusts mist output to maintain your set humidity level (e.g., 50%), turning on when it drops 5% below and off when reached. No manual intervention needed.

The 6-liter tank provides up to 60 hours of runtime on the lowest setting. Even on medium settings, you can easily get 2-3 days without refilling, making it ideal for busy households.

Excellent choice! The large 6L capacity and auto humidity control are perfect for extremely dry climates. Many Reddit users in Colorado specifically praise the 300S as a 'game changer' for maintaining comfortable humidity year-round.

Yes! The VeSync app lets you turn it on/off, adjust mist levels, set schedules, and monitor humidity from anywhere. Perfect for turning on the humidifier before you get home.
