Outdoor vs. Indoor Air Quality: Why Personal Monitoring Matters
Nearly 99% of the global population breathes air that exceeds WHO air quality limits, exposing them to harmful pollutants like fine particulate matter and nitrogen dioxide. Even in cities with monitoring networks, localized pollution events can go unnoticed—leaving you unaware of the air quality in your immediate surroundings.

Outdoor Monitoring
AirU monitors connect to AirView, giving you real-time data and mapping so you can see how outdoor air quality changes around you, helping you avoid pollution hotspots and respond to environmental events.

Indoor Monitoring
AirU personal monitoring lets you track air quality in your home, office, or workspace, helping you identify trends, detect pollution sources, and make informed choices for cleaner indoor air. Stay in control with real-time data and historical insights to create a healthier environment.
How does
it work?
AirU Pro air quality monitors capture ambient air through advanced sensors, uploading precise measurements to the TELLUS Cloud while securely backing them up on an onboard SD card.
Access and analyze your data anytime through your personal dashboard for actionable insights.

Highly respirable particles that cause asthma and adverse cardiac effects, and even promotes cancers.
Indicative of engine exhaust, vehicle traffic.
Breathing ozone is like getting a sunburn on your lungs. Ozone is a strong oxidizing gas that causes asthma and asthma exacerbations as well as respiratory inflammation.
VOCs can cause headaches and dizziness. Many VOCs are air toxics, and some are carcinogens.
This is an important greenhouse gas and a key indicator of home and building ventilation.
This is a highly toxic product of incomplete combustion that can tragically cause the death of residents. All homes should have a CO monitor and warning system.

The AirView Map and Dashboard are your gateways to understanding air quality micro-climates and identifying pollution contributors through visualizations and alerts, keeping your community informed.
With AirView you can view and download raw and modeled air quality data to support data-driven decisions.
TELLUS CoreDI is the culmination of over 15 combined years of rigorous multidisciplinary research, born out of the University of Utah. Focused on high spatial resolution air quality monitoring that is both economical and reliable. Designed to be integrated by local organizations and municipalities with a high degree of trust in the data.
A highly entwined, multi-tier hardware-software ecosystem that ensures the most accurate data collection and representation.
A suite of statistical tools developed in-house and refined over the last five years using trillions of data points spanning multiple regions across the globe to screen for outliers and flag erroneous measurements in real time.
Integration of 3rd party ground-truth data sources to continuously apply [update] in situ field calibrations to the network to correct for ever-changing environmental conditions and ensure the most accurate and trustworthy data.
Machine-learning-based spatial and temporal interpolation functions to reliably provide pollution information between data sources to provide pollution measurements anywhere in the network region.
