FAQs: Evaporative vs. Ultrasonic Humidifiers

1. How often should I clean my humidifier?
Clean every 3-7 days using white vinegar to prevent mold. Follow the manufacturer’s guide for deep cleaning. Learn maintenance tips for appliances.

Only models with dedicated trays (e.g., LEVOIT, Everlasting Comfort) support oils. Adding oils elsewhere may damage the unit.
