1. Technology overview
IQAir traces its origins to a workshop in Germany in 1963, moved operations to Switzerland in 1981 and is headquartered in Steinach, Switzerland, through IQAir AG. Known for air purification, it acquired AirVisual in 2017 and publishes the annual World Air Quality Report, giving it a large global air quality data network.
For organisations, the AirVisual Outdoor monitor measures PM1, PM2.5, PM10, temperature, humidity and pressure, with an optional CO2 module, Ethernet, Wi-Fi or 4G and accuracy verified by the Swiss Federal Institute of Metrology (METAS). AirVisual Pro covers indoor spaces. The enterprise dashboard adds multi-site management, location grouping, threshold and offline alerts, reports, a device API and BMS or HVAC integration. Target users include schools, offices, hospitals, hotels and embassies.
2. Highlighted features & specifications
- AirVisual Outdoor: weatherproof PM1, PM2.5 and PM10 monitor with optional CO2 module.
- AirVisual Pro: indoor monitor for classrooms, offices and clinics.
- Enterprise dashboard: multi-site management, workspaces, group averages and bulk settings.
- Alerts and reports: threshold and offline email alerts plus automated reports.
- Device API: access to own device data, historical and raw data downloads.
- Building integration: smart control of HVAC and HEPA filtration via API.
3. Potential application
International schools in Hanoi can combine outdoor and classroom monitors to decide on outdoor activities and run purifiers automatically. Hotels and serviced offices can display indoor air data to guests and tenants. Hospitals and clinics can monitor PM2.5 and CO2 in waiting areas and link readings to HVAC control.
4. Benefits
METAS-verified accuracy and no required recalibration reduce maintenance for outdoor monitors. Indoor and outdoor comparison helps facility teams decide when to ventilate or filter. API-based control of HVAC and filtration systems turns readings into automatic action, and reports help buildings meet WELL and LEED healthy air requirements.
5. Market trends & opportunities
Employers, schools and hospitality operators are adopting indoor air quality monitoring as part of healthy building and ESG programmes, while public awareness of PM2.5 keeps rising through apps and air quality rankings. Hanoi and Ho Chi Minh City regularly appear on public air quality maps, increasing demand for on-site measurement.
6. Other information
IQAir was started in Germany in 1963 by brothers Manfred and Klaus Hammes and moved to Switzerland in 1981. IQAir AG in Steinach serves as headquarters for regions outside North America and China. It acquired AirVisual in 2017 and is an air quality monitoring partner of the UN Environment Programme.
