When the open-plan room gets dry
Large rooms with high ceilings dry out quickly in winter. Nimbus emits up to 650 ml/h and spreads the moisture through the adjustable nozzle.
Put it where it's needed
Nimbus stands on the floor or a low table. Choose comfort, turbo or sleep and one of five mist levels on the panel.
What's included
In the box you'll find the humidifier with tank, nozzle and aroma tray. The descaling cartridge and water filter are built in.
Product FAQ
Is warm mist safe with children at home?
In warm mist mode the water is heated. Place the unit steadily where children and pets can't reach it, don't touch the nozzle while it's running and let it cool before moving or cleaning it. With children in the room, cool mode is the safe choice.
What humidity should I aim for?
Indoors, 40–60 % relative humidity usually feels comfortable. With the radiators on in winter, indoor air can drop to 20–30 %. Set the level you want and let the humidity sensor do the work – above 60 % is rarely needed and can cause condensation on cold windows.
How often should I change the water?
Wilfa recommends clean water and refilling the tank at least every third day. Empty and rinse the tank when you're not using it.
Are scented oils included?
No. Scented oils aren't sold here. Only use the aroma compartment or pad as the manual describes – never pour oil into the water tank unless the manufacturer explicitly says you can.
How do I clean it?
Empty the water and let the parts dry when you're not using it. Clean the tank and filter about once a week as the manual describes – with water and a soft brush, and descale when needed. Never leave old water standing for days.
How fast will it arrive, and can I change my mind?

It has three programmes – comfort for everyday use, turbo when humidity needs to rise quickly and sleep for the night – and five mist levels. The nozzle is adjustable so you can spread the moisture through the room.
