Why monitor indoor air quality?

Clean, fresh air is fundamental to life and health, and yet repeated studies have revealed that in many cases the air you’re breathing at school, in the bus or at work and probably also at home falls well below the ideal of what clean, fresh air should be.

Ventilation (replacing old stale air with clean fresh air) is the most effective and economical method of improving and maintaining high indoor air quality, but without monitoring to reveal the otherwise invisible air quality details, it's easy to overlook ensuring that adequate ventilation is provided.'s goal is for ventilation monitoring to be easy and accessible so everyone can benefit from well ventilated indoor spaces.

The benefits of clean, fresh air


Stale air contains odours, feels "stuffy" and leads to reports of headaches and other discomfort.

Reduced infection risk

Clean air lowers the risk of transmission of respiratory viruses such as Covid-19 as well as common colds and the Flu. [ref]

Improved productivity

Stale air containing high CO2 levels slows response times and decreases overall productivity of office workers. [ref]
