This humidifier from Zojirushi offers three temperature settings: high, warm, and low, and is easy to maintain with no filter required. - Brand: Zojirushi - Model: EE-RP50-WA - Color: White - Features: High, warm, and low settings - Modes: Strong, Soft, and Moderate - Filter: Filter-free I used this until last year, but I'm selling it because I bought a new one. The inside has been cleaned with citric acid detergent, but there are some scratches and scuffs on the bottom. The box, instruction manual, and power cord are all included. Thank you for looking.
