Stadler Form Karl Humidifier in Black

Karl’s evaporator system works by drawing air through a wick filter to release clean, natural vapour without the need for heat or ultrasonics, ensuring even distribution without wet spots on furniture. Just lift the flap to refill the 4 L tank with tap water from above – even while it’s running – and let the built-in hygrostat keep humidity levels steady at your preferred setting. The app adds a layer of ease, letting you check humidity from your phone or set schedules, which is handy for larger spaces where air can dry out quickly from heating or ventilation. Its stable base and spill-resistant design make it family-friendly, and the included Water Cube helps prevent bacterial buildup for fresher air day after day.

A Red Dot Award winner for 2023, the Karl stands out for its balance of power and subtlety, humidifying larger areas effectively while frugally sipping energy. People appreciate the straightforward cleaning – rinse the tank every few days and descale periodically in hard-water areas to keep it running smoothly season after season. At under 3 kg, it’s easy to move between rooms, and compatible accessories like extra filters or Hygiene Tabs let you customise for harder water or added freshness (though skip fragrances to protect the unit). Whether combating winter dryness or central heating effects, Karl delivers consistent comfort that supports better breathing and a healthier home environment.
