Getting the Balance Right in the Classroom between Ventilating the Classroom and keeping Teachers and Students warm through the winter months

Indoor Classroom Air Quality Monitoring

Staying safe & warm through the COVID19 pandemic is paramount to everyone and keeping school classrooms as safe as possible is key. To ensure good ventilation it's tempting to keep the windows open in the classroom all the time, but a cold, draughty classroom has a negative impact on learning, and may lead to other kinds of health problems.

ZiggyTec's ClassFresh monitor offers a balanced solution

ZiggyTec's ClassFresh air quality monitor is a stand-alone battery-operated unit that is simply placed on the classroom wall. We situate a small tablet display on the wall close to the teachers' desk.


ClassFresh monitors CO2 levels in classrooms and indicates to teachers using a simple traffic light system whether or not a window needs to be opened to ventilate the classroom.


Data is also recorded on the ClassFresh Cloud Platform which provides valuable data for identifying trends, troubleshooting and verifying solutions, as seen below.

The wall-mounted display informs the teacher when to open or close the classroom windows:

You definitely should open a window and allow the fresh air in to circulate

You can close some windows if you wish as ventilation is currently good

CO2 levels are rising in the room you should open some windows
