- How often do I need to refill it?
- The 1.5-gallon tank lasts up to about 70 hours on low. On higher speeds expect to refill every day or two.
- Does it work in a large living room?
- It is rated for rooms up to roughly 426 square feet. In open-plan spaces above that, expect it to struggle to raise humidity.
- Will it leave white dust?
- Ultrasonic models can leave white dust when filled with hard tap water. Use distilled or filtered water to avoid it.
- Does it shut off automatically?
- Yes. It shuts off when the tank runs dry and when the humidistat reaches your set level.
- Can I use essential oils in it?
- No. This model is not designed for essential oils; adding them can damage the ultrasonic plate and void coverage.
- How loud is it?
- It is quiet in normal use, with a soft water trickle. Most owners find it fine for sleeping.
- Where is the Homedics TotalComfort Deluxe Ultrasonic Humidifier cheapest?
- At Kohl's, for $119.99, as of our latest check.
