## At a glance

- Top-fill design is described as allowing refills without lifting or flipping the tank, and the wide opening is intended to aid cleaning.
- The 360° adjustable nozzle lets users direct the cool mist.
- The up-to-40-hour runtime is specified for continuous mist on the low setting, not as an unconditional runtime.
- The listing says essential oils can be added directly to the water tank for fragrance.

## Pros

- 3.5-litre capacity and a low-setting runtime claim of up to 40 hours may reduce refill frequency during overnight use.
- Top filling and a wide opening are useful practical details for refilling and cleaning.
- Adjustable mist direction, touch controls, auto shut-off and a night light provide several listed convenience features.

## Before you buy

- The listing's 500-square-foot coverage, 28dB noise level and seven-colour light are stated in feature text, while its structured details provide different levels of specificity or do not confirm those figures. The 40-hour runtime applies to low mist, and the listed 230 Volts should be checked for suitability with the intended power supply. The filter-type field contains unrelated German text, so the filter specification is unconfirmed.

## In the box

- Machine body (Included)

## A good fit for

- Bedrooms or home offices where a cool-mist humidifier with a night light and adjustable nozzle is wanted.
- Buyers prioritising fewer refills, provided they understand the 40-hour claim applies to low mist.

## Less suited to

- Buyers who need a confirmed noise rating, verified coverage area or a clearly specified filter type.
- Anyone needing a cordless humidifier or a runtime above the stated low-setting claim.

## Frequently asked questions

### How long is the claimed runtime?
The listing claims up to 40 hours of continuous mist on the low setting. It does not establish that runtime for other settings.
### How is the tank refilled?
The product is described as top-fill, so the tank can be refilled from above without lifting or flipping it.
### Can essential oils be used?
The listing says a few drops can be added directly to the water tank. Follow the product instructions for use and cleaning.
### What room coverage is stated?
The structured details list 500 Square Feet, but the supplied information does not independently verify that coverage claim.
