Product details
The Wuerfeli (Swiss Made) visualises your air quality and reminds you to ventilate. The handmade fabric bag and the power cable from LE CORD made of recycled plastic complete the scope of delivery.
Fresh air like in the mountains
Targeted ventilation increases your ability to concentrate, protects your immune system and has a preventive effect against mould. The four-coloured pyramid is the result of two extensive air studies, which takes intuition and air quality to a new level.
Sufficient oxygen
On average, you spend 90% of your time indoors. You consume about 11,000 litres of air every day. To ensure that the air is as oxygen-rich and fresh as outside, the Wuerfeli colourfully shows you when you should open the windows and when you can close them again.
Maximum fresh air with minimum energy loss
Discover the invisible ways of air. With the Wuerfeli breathing function, you too can become a ventilation professional.
Fast pulsating = rapid air exchange (e.g. shock ventilation)
Slow pulsation = more is possible. Try to enlarge the air channel.
Automatically visible
Thanks to its efficient design, a Wuerfeli uses about 30 times less electricity than an LED 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 in an understandable way
Blue: Close the window! You never fill your lungs with stale air
(400 - 550 ppm CO₂ ↔ 0 vol. % exhaust air)
Green: You fill your lungs with stale air about every 15 minutes.
(550 - 1000 ppm CO₂ ↔ 0 - 1.5 vol. % exhaust air)
Orange: You fill your lungs with stale air about every 5 minutes.
(1000 - 1600 ppm CO₂ ↔ 1.5 - 3 vol. % exhaust air)
Red: Open the window! You fill your lungs with stale air about every 2 minutes
(1600 ppm CO₂ or more ↔ over 3 vol. % exhaust air)
Definition of exhaust air: Exhaled air from people indoors, expressed in volume percent.
