The cube (Swiss Made) visualises your air quality and reminds you to ventilate. The handmade fabric bag and the power cable from LE CORD made from recycled plastic round off the scope of delivery.
Fresh air like in the mountains. Targeted ventilation increases your ability to concentrate, protects your immune system and has a preventative effect against mould.
Sufficient oxygen. On average, you spend 90 % of your time indoors. This means you take in around 11,000 litres of air every day. To ensure that the air is as oxygen-rich and fresh as outside, the Wuerfeli shows you in colour when you should open and close the windows.
Maximum fresh air with minimum energy loss. Discover the invisible paths of air. With the Wuerfeli breathing function, you too can become a ventilation pro. Fast pulsation means rapid air exchange (e.g. shock ventilation), slow pulsation means that there is still more to do. Try to enlarge the air duct.
Automatically visible. Thanks to its efficient design, a Wuerfeli consumes around 30 times less electricity than an LED light bulb. The Wuerfeli always adapts to the lighting conditions in your room and is also suitable for your bedroom. Light off, Wuerfeli off.
Intuitive colours explained clearly:
Blue: Window closed. You never fill your lungs with stale air (400 - 550 ppm CO₂).
Green: You fill your lungs with used air about every 15 minutes (550 - 1000 ppm CO₂).
Orange: You fill your lungs with stale air (1000 - 1600 ppm CO₂) about every 5 minutes.
Red: Open the window. You fill your lungs with used air (1600 ppm CO₂ or more) about every 2 minutes.
Exhaust air definition: Exhaled air from people indoors, expressed as a percentage by volume.
