  See Stadler Form Oskar in action:

Meet the Stadler Form Oskar Big - one of the largest humidifiers in its class that is suitable for rooms sized up to 100 m². It features a unique V4 filter technology that prevents over-humidification, an adjustable hygrostat control and a large 6-litre water tank. Say goodbye to cracked lips, skin dryness and itching. Oskar Big is ready to take your comfort to the next level.  

  Excellent choice for:

  • Shoppers with rooms up to 100 m2

  • Those who live with eczema or naturally dry skin.

  • Customers who want to soothe the symptoms of dry mouth, eyes and throat.

  • Buyers who place a high value on low running costs.

  • Customers who prefer a device with a fragrance container. 

  • Those who want a large water tank.

  Why we love it:

  • Adjustable hygrostat control (the humidity can be set between 40% and 55%).

  • Inbuilt humidity sensor for maintaining a selected humidity level.

  • 4 humidity output levels. The higher the level, the stronger the mist output will be.

  • Can act as an aroma diffuser by adding your favourite fragrance to the water tank.   

  • Cheap to run, as it uses only 30 watts of power at its top output level. 

  • Uses ecological filters that are made of plant and textile fibre.

  • Easy to clean and maintain.

  • Large capacity 6-litre water tank.

  • Automatic shut-off function for safety. 

  • The memo function reminds you when to replace the filters.

  • In night mode, the evaporator works almost unnoticed.

  • Red Dot Design Award winner.
