Discover how we work.

AirGuard is an indoor air management company, based in Hong Kong, that specialises in measuring and monitoring indoor air quality and also deactivating airborne bacteria and viruses - so providing a safe indoor environment for everyone, everywhere.

  • Measure

    We install a network of state-of-the-art IoT sensors throughout the space, continuously sampling the indoor air quality to highlight any potential issues.

  • Mitigate

    Upon the initial data analysis, we will provide a detailed preliminary report on your indoor air quality and any personalised solutions we see fit for your space. This may include the deployment of our Active Germ Suppression Units (AGS).

  • Manage

    Your indoor air will be continuously monitored for changes or sub-optimal indoor air quality. These data will be visualised on a dashboard display to which you will have full access, or in the form of a customer-facing kiosk display.
