⚡ At a Glance
- • Tank Capacity: 4L tank delivers extended operation for overnight use
- • Best for: Bedrooms, nurseries and larger rooms needing sustained humidity
- • Not ideal for: Small desktops or travel where compact size is essential
A 4L humidifier uses high-frequency ultrasonic atomization to produce ultrafine 5μm mist. Dual-intake with a 4-inch outlet projects mist for wider coverage while operating at around 28 dB.
Long, quiet nights – thanks to a 4L tank and ultrasonic atomisation
A 4-litre reservoir supports up to 36 hours of continuous mist, while high-frequency ultrasonic atomisation breaks water into 5μm ultrafine particles. Measured noise drops to about 28 dB thanks to the low-vibration motor design.
Extended runtime reduces refills for overnight use and quiet operation keeps sleepers undisturbed. Smaller mist particles humidify air without leaving surfaces wet.
Faster room coverage – with dual-intake and a 4-inch mist outlet
Dual-intake draws air into the unit as a four-inch outlet projects a supersized mist column reaching up to 40 inches. The combination increases distribution speed so humidity spreads more evenly across larger spaces.
Humidity reaches further into the room faster, so relief from dry air happens sooner. Useful in larger bedrooms or shared rooms where single-point misting can be slow.
Easy upkeep and mood control – with top-fill design and 3-in-1 functionality
Top-fill access lets water be added without inverting the tank, while modular components are simple to remove for cleaning. The unit also supports aromatherapy and includes an ambient night light; compatibility with a demineralisation cartridge helps reduce limescale.
Quick refills and straightforward cleaning cut maintenance time and effort. Ambient lighting and essential-oil support let rooms feel more relaxing, noting that oils and cartridges are sold separately.
