How Our Indoor Air Quality Monitoring Works
Clear The Air delivers professional indoor air quality monitoring services for businesses and homes across the UK and Europe. Every device comes with a one-time hardware cost plus a simple monthly subscription, giving you continuous access to our monitoring platform, mobile app and real-time alerts with no hidden costs.
The CTA-PRO - Built for Professional Environments
Most consumer air quality monitors measure one or two things. The CTA-PRO measures six simultaneously. CO₂ to detect poor ventilation before it affects productivity or health. PM2.5 to monitor fine particulate matter linked to respiratory conditions. TVOC to track total volatile organic compounds from materials, cleaning products and furnishings. CO to detect carbon monoxide, a silent and potentially fatal hazard. Temperature for comfort and compliance monitoring. Humidity for damp detection. All from a single compact device measuring just 84 x 84 x 33mm, small enough to sit discreetly on any wall or surface.
What Makes It Different
No WiFi required. Unlike every other air quality monitor on the market, the CTA-PRO uses NB-IoT connectivity with an integrated eSIM. It works anywhere in the UK and Europe with no network configuration, no IT department sign-off and no dependency on your building's WiFi infrastructure.
Up to 2 years battery life. Reading sensors every 15 minutes and transmitting every 2 hours, the CTA-PRO runs for up to 2 years on a single battery. Deploy it and forget it.
Industrial-grade sensors. The CTA-PRO uses industrial-grade environmental sensors, not the consumer-grade components found in cheaper monitors. CO₂ accuracy to ±40ppm, PM2.5 resolution to 1μm, CO resolution to ±5ppm.
Full API integration. Connect to your building management system, CAFM platform or any third-party software via our open REST API. Your data, your systems.
Motion detection included. An integrated 110° motion sensor with 5m range means the device can trigger alerts based on occupancy, useful for healthcare and education environments.
