- Is $89.99 a good price for this humidifier?
- It is the only new price on record as of November 3, 2026, at Amazon, so there is no lower store price to compare against. Comparable smart 3 L ultrasonic humidifiers usually sell in the $60 to $100 range, so $89.99 is mid-to-high but not unusual for one with a humidity sensor and app control.
- How often do I need to refill the tank?
- At the full 250 mL/hr output the 3 L tank lasts about 12 hours, so roughly one refill a day. On low or sleep settings it can stretch past a full night and into the next day.
- Will it cover a large living room?
- No. Dreo rates it for about 300 sq ft, which is a bedroom or small office. For open-plan spaces you would need a larger console humidifier.
- Does it work with essential oils?
- Yes, it is listed for aromatherapy use and includes a medicine cup. Add oils only to the designated cup or tray, not into the water tank, to avoid damaging the ultrasonic plate.
- What comes in the box?
- Expect the humidifier base, the 3 L removable tank, a medicine cup and a quick-start guide. A power adapter is included; replacement filter pads, if used, are sold separately.
- When is it cheapest?
- Dreo humidifiers tend to drop during fall cold-and-flu season sales and Black Friday events. With only one store listing it, watch that Amazon price rather than expecting cross-store discounts.
