1 / 7Delletir 6L Top-Fill Ultrasonic Cool Mist Humidifier
The Delletir humidifier is a 6-liter top-fill ultrasonic cool-mist model listed for bedrooms, living rooms, offices and nursery use. Its long low-setting runtime and refill-from-the-top design may suit buyers seeking fewer refills, while feedback is mixed on mist output and reliability.
At a glance
- The top-fill opening lets you add water without removing the tank, and the listing says its wide opening simplifies cleaning.
- The claimed runtime of up to 50 hours applies on the low setting, so operation at stronger mist settings may require more frequent refills.
- A control knob adjusts mist output, and the listing describes automatic shut-off when water runs low.
- A seven-color ambient light is listed alongside ultrasonic operation and quiet-running claims.

What to know before buying
- The listing describes this as suitable for large spaces but does not provide a coverage area or mist-output rate. The listed dimensions, 3"D x 3"W x 5"H, also appear unusually small for a 6-liter humidifier, so confirm the product dimensions and room suitability before buying.

Customer feedback highlights quiet operation and lighting, with customers also describing the humidifier as working well. Reports are mixed on reliability and humidity output, including feedback that a unit stopped working after two months and that mist was weak. The stated 6-liter capacity and low-setting runtime may be useful for extended operation, but they do not establish consistent mist strength or durability.
Positive themes
- Customers report appreciating the quiet operation and lighting.
Mixed feedback
- Feedback on reliability and humidity output is mixed. Some report good operation, while others mention early failure or weak mist.
Frequently asked questions
How long does it run between refills?
The listing claims up to 50 hours of operation on the low setting. It does not specify runtime at higher mist settings.
How do you refill it?
It has a top-fill design that allows water to be poured in without removing the tank. The listing also describes a wide opening intended to simplify cleaning.
Does it shut off when water runs low?
The listing claims an automatic shut-off feature that activates when water runs low.
What room size does it cover?
A room-coverage area is not stated. Although the listing calls it suitable for large spaces, buyers needing a defined coverage figure should not assume one from that description.
