What does ventilation do against viruses?

When we exhale, we spread aerosols. Viruses get into the air through this. With regular ventilation, we reduce the amount of aerosols in the air and thus the risk of infection - for example with corona.

AND BY THE WAY:Fresh air keeps us awake, helps us to concentrate and makes us more productive.

This is how it works

The air is fresh.
< 1000 ppm CO2

Airing is done quickly and easily forgotten. All the better if everyone in the room helps out. It's now very easy with CARU air. Because anyone can read traffic lights. And it's also fun.

Ventilate soon.
1000 - 1400 ppm CO2

Until now we could only guess when it would be time to ventilate again. With CARU air you now know exactly: as soon as yellow and at the latest when red.

> 1400 ppm CO2

When it's time to ventilate, we should also know how: Open as many windows and doors as possible at the same time and fully. Ventilation is the motto. And that until the CARU air flashes green again.

High quality CO2 sensor.

CARU air stands for Swiss quality. That is why we rely on the high-quality CO2 sensor from Sensirion: For efficient and sustainable ventilation, especially in the cold autumn and winter months.

High data security.

That is important to us. That is why CARU air neither records data nor stores it in the cloud. We think:The moment to ventilate is what matters.

Who is behind it.

At CARU, we are a leading global AgeTech company from Zurich. Our core product:a voice-controlled emergency call with chat function. CARU air is also recently part of the portfolio.

With both products, we pursue one goal: high quality of life - from young to old.
