KAY mini - The intelligent CO2 light for offices, meeting rooms, retail, law firms and to take away

The CO2 light KAY mini is the ideal partner in all types of rooms, because thanks to its "breathing" sensors, it warns actively if the CO2 threshold values ​​are exceeded due to insufficient fresh air supply due to excreted aerosols. On the basis of permanent measurements, KAY mini gives a ventilation notice that lights up according to the traffic light principle, thus reducing the spread of pathogens through the air and thus lowering the risk of infection. Correct ventilation plays a central role in combating disease in order to effectively lower the aerosol concentration in the room and the associated risk of infection. KAY mini provides security, trust and a hygienically routine ventilation system in closed rooms in times of viral diseases such as corona or flu.


KAY mini is also suitable for on the go to take with you to meetings or private parties thanks to the USB power supply via a USB charger or a USB power bank.

Using the example of office and meeting rooms, retail and law firms: When should the air be ventilated? Here, most users rely on the 20-5-20 rule proposed by the Federal Environment Agency. That means after 20 minutes of class airing for five minutes, so that the next 20 minutes in this room can then be held in a healthier indoor climate.
But outside temperatures in the minus range or customers, colleagues and clients who are freezing or sitting in drafts for a long time often make this model difficult with five minutes of ventilation. Here it is definitely an advantage to ventilate only then and only as long as / as necessary and is indicated with the help of KAY mini. The CO2 traffic light shows reliably and precisely to the second whether ventilation must be carried out soon (YELLOW) or immediately (RED) or whether the air in the room is still “fresh” enough (GREEN).





- The light principle clearly shows “bad air” in the premises
- KAY can be used mobile and only requires a standard power supply
- An integrated CO2 sensor measures the indoor air quality permanently and "breathing" and evaluates it for the carbon dioxide concentration
- KAY is ideal as a tabletop device
- A reliable reminder of regular intermittent and cross ventilation thanks to the traffic light principle
- Immediately more security and hygienic indoor air for colleagues, customers and clients

- CO2 measurement according to WHO standard
