Indoor air quality monitors

Make indoor conditions safer, healthier, and better with sensor monitoring.

Reduction of the risk of infection with viruses or bacteria

The higher the CO₂ concentration in the room, the greater the potential for contamination with viruses and bacteria. Better ventilation helps to contain infections via aerosols and droplets and to reduce the number of new infections.

The future of improving indoor air quality

When we think of air quality, we tend to think of air pollution in the regions surrounding our homes. We rely on measures such as the Air Quality Index to let us know when airborne pollutants in our towns or cities reach levels that may cause or exacerbate health issues.
