Levoit - Dual 200S .79 gallon Smart Top-Fill Humidifier - White

The Dual 200S is only a cool humidifier. However, you can add essential oils to the base (once filled with water) to create a light aroma from the humidifier.

The filter can last up to a month, depending on the quality of the water and how often the humidifier is used. You can soak the filter in distilled white vinegar and then rinse it under warm water to clean it.
