The Wuerfeli (Swiss Made) visualizes your air quality and reminds you to ventilate. The handcrafted fabric pouch and the practical direct connection complete the package.

Fresh air like in the mountains. Targeted ventilation enhances your concentration, supports your immune system, and acts preventively against mold.

Sufficient oxygen. On average, you spend 90% of your time indoors, inhaling about 11,000 liters of air daily. To ensure the air is as oxygen-rich and fresh as outside, the Wuerfeli brightly indicates when you should open and close the windows.

Maximum fresh air with minimal energy loss. Discover the invisible pathways of air. With the Wuerfeli breathing function, you too can become a ventilation pro. Quick pulsation means rapid air exchange (for example, cross-ventilation), while slow pulsation indicates that there is still more to be done. Try to enlarge the air channel.

Automatically visible. Thanks to its efficient design, a Wuerfeli consumes about 30 times less power than an LED light bulb. The Wuerfeli always adapts to the lighting conditions in your room and is also suitable for your bedroom. Lights off, Wuerfeli off.

Intuitive colors explained clearly:

Blue: Windows closed. You never fill your lungs with stale air (400 - 550 ppm CO₂).

Green: You fill your lungs with stale air approximately every 15 minutes (550 - 1000 ppm CO₂).

Orange: You fill your lungs with stale air approximately every 5 minutes (1000 - 1600 ppm CO₂).

Red: Windows open. You fill your lungs with stale air approximately every 2 minutes (1600 ppm CO₂ or more).

Definition of exhaust air: Exhaled air from people indoors, expressed in volume percent.
