What to know before buying
Listing details to confirm
Listing details are contradictory or inconsistent: the title gives 3L capacity, the component list says 4.2L, while another specification lists 3 Liters. Coverage is listed as both 290 Square Feet and 40 m². The model name Neoclassic 450s and model number LUH-D302-WUK also appear alongside a description naming Dual 150. Confirm the selected product’s capacity, coverage and model before purchase. The 25 minutes runtime entry is also inconsistent with the stated function and should not be treated as a dependable runtime specification.

Frequently asked questions
What tank capacity does the listing specify?
It is inconsistent. The title says 3L, the details list 3 Liters, and the included-components entry describes a 4.2L humidifier. Confirm the capacity for the selected listing.
Can it adjust humidity automatically?
The feature text claims an Auto Mode that adjusts output based on room humidity, as well as selectable mist settings.
Can it be controlled from a phone?
The listing claims nursery humidity monitoring and remote adjustment from a phone. Confirm the selected model supports the described feature.
What runtime should buyers expect?
The specification lists 25 minutes, but this conflicts with the humidifier's stated use and should not be relied on as a confirmed runtime.
