- How is this different from a warm mist humidifier?
- It makes cool mist with an ultrasonic plate instead of boiling water, so it is quieter and uses less power. Warm mist units boil water, which sterilizes it but uses more electricity and carries burn risk around kids.
- Do I need distilled water?
- Distilled or filtered water is best. Tap water leaves white mineral dust on furniture and builds scale on the ultrasonic plate, which shortens the unit's life.
- Does the essential oil tray work like a diffuser?
- It adds scent to the mist as it passes through, but it is not a concentrated diffuser. Use a few drops of oil and clean the tray between scents so residue does not clog it.
- How often should I clean it?
- Rinse the tank and wipe the base every few days, and do a deeper descaling clean about once a week with a vinegar and water soak. Skip it and you get film, odor, and weaker mist.
- What size room does it suit?
- Cool-mist ultrasonic units of this type work best in bedrooms and small rooms. For a large open living area, expect to run it longer or look at a larger output model.
- Does it shut off when the tank is empty?
- Nothing in the product details confirms an automatic shutoff, so check the tank level and switch it off before it runs dry.
