Airthings manufactures smart indoor air quality and radon monitoring devices that give building occupants and facility managers real-time visibility into environmental risks — radon, PM2.5 particulate matter, CO2, VOCs, humidity, and temperature. 

Their 7-in-1 sensor technology feeds a companion app and business dashboard, translating invisible air quality data into actionable insights, with an API available for facility managers who want air quality data integrated into their own building management systems. On the business side, their "Airthings for Business" line targets facility managers and schools pursuing air quality certifications and workplace wellness benchmarks, positioning them as a monitoring/diagnostics layer that complements (rather than replaces) mechanical ventilation and filtration equipment.
