Reference monitoring alone cannot provide complete local coverage
Reference stations provide highly accurate air quality measurements, but their limited number can make it difficult to understand variation across towns, cities and operational sites. Zephyr® helps organisations expand monitoring coverage with trusted, indicative measurements and clearer local air-quality insights.
Features include:
Real-Time Monitoring
Access trusted indicative measurements and respond quickly to changing conditions.
Flexible, Easy Deployment
Solar, mains and battery powered options for a wide range of environments.
Network Deployment
Deploy monitoring networks across towns, cities and operational sites.
Integrated Insight
Access Zephyr® measurements through MyAir® or via API integration for mapping, trend analysis, and reporting.
Alerts & Notifications
Receive alerts for exceedances, system status and changing air quality conditions.
Managed Service & Support
Calibration, QA/QC processes, cartridge replacement and ongoing maintenance included.
Monitor key gases and particulates in real time
Zephyr® with replaceable cartridge system
Our air quality monitoring solutions are supported by ready-to-use calibrations validated through independent global comparisons against reference-grade equipment. This gives confidence that Zephyr® can meet indicative data quality objectives for ambient air quality monitoring, as outlined in EU Directive 2024/2881 and CEN/TS 17660
Trusted through calibration, co-location and validation
Zephyr® performance is supported through ongoing calibration, co-location studies and comparison against reference-grade equipment. This continuous validation approach helps maintain confidence in data quality across different environments, pollutants and applications.
By combining quality assurance processes with performance assessments from deployments around the world, EarthSense helps organisations access trusted air quality insight for operational, planning and reporting purposes.

New: Indicative environmental noise monitoring
Air quality tells part of the story. Environmental noise completes it.
Environmental noise is becoming an important part of planning, environmental assessment and community wellbeing. The Noise Cartridge adds indicative environmental noise monitoring to Zephyr®, enabling air quality and noise measurements from a single device, managed through MyAir®.
One device. One platform
Measure air quality and environmental noise from a single Zephyr® monitor, with all data available through MyAir®.
Reduce cost & complexity
Eliminate the need for separate hardware, installation, maintenance and software platforms.
Simple to Deploy & Upgrade
Compatible with existing and new Zephyr® and Zephyr S® deployments through a simple cartridge upgrade.
Privacy Assured
Measures sound levels only. No audio is recorded, stored or transmitted, helping protect privacy in public and community environments.

Trusted by organisations delivering better environmental outcomes
Working with Leicester City Council, EarthSense helped improve understanding of the impact of domestic wood burning on air quality. By combining Zephyr® monitoring with high-resolution MappAir® modelling, the project identified pollution hotspots, supported the Council’s Air Quality Action Plan and helped inform public health initiatives.
University Hospitals Plymouth NHS Trust used Zephyr® monitors and the MyAir® platform to support its Clean Air Hospital ambition. The project identified pollution sources, informed targeted clean air initiatives, and supported the Trust’s Green Plan and NHS net-zero commitments.
