Welcome to LUFT-GUET.CH

Thanks to LUFT-GUET.CH you always know that the air quality in your classroom, meeting room or office is optimal.

LUFT-GUET.CH reminds you with a simple traffic light system to ventilate when the CO2 content in the room is too high.

Regular airing increases the ability to concentrate and can protect against infections. Especially in closed rooms
without air circulation is a possibility, that someone could be infected through an aerosol cloud even minutes after another person has left the place.

Another added value of the LUFT-GUET.CH traffic light is the energy saving, you are airing only when it is necessary.
