# Delletir 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.

## Pros

- Top-fill access is designed to make refilling easier without lifting off the tank.
- The 6-liter tank and claimed 50-hour runtime on low can reduce refill frequency when used at that setting.
- Mist output is adjustable, and automatic shut-off is claimed for low-water conditions.

## Before you buy

- 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.

## In the box

- Machine body (Included)

## A good fit for

- People wanting a top-fill humidifier with a relatively large stated tank capacity and an extended low-setting runtime.
- Bedroom, living room or office users looking for adjustable cool mist and an ambient light feature.

## Less suited to

- Buyers who need a specified room-coverage area or a quantified mist-output rate, neither of which is provided here.
- Buyers who need customer feedback showing consistent long-term reliability or consistently strong mist output.

## Customer feedback

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.
