Monitor Air.
Advance Science.
Air pollution is the world's largest environmental health threat, yet vast data gaps remain. We are launching this global citizen science initiative to empower citizens with commercial-grade air quality monitoring technology to build the world's largest open air quality database and drive change.
*Hardware fully subsidized by charitable donations.

A Global Effort to Democratizing Data for a Healthier Future
Air quality is a fundamental human right. This initiative bridges the gap between individual awareness and global scientific progress through three core pillars.
Access
Science Without Barriers
Cost should never prohibit contribution. Through charitable donations and a partnership with the Global IAQ Observatory, we provide commercial-grade IAQ monitors to participants at zero cost.
Action
Community-Led Research
Join a global network of individuals acting as citizen scientists. You aren't just a user; you are a contributor. By joining the movement, you become a vital part of a decentralized scientific network, filling critical data gaps in your region.
Impact
Evidence-Based Change
Data drives change. Use the data for yourself to breathe better today, and contribute to the centralized dataset that gives researchers and legislators the hard numbers they need to fight for cleaner air standards globally.

Commercial Grade Quality
To build a scientifically valid global database, we equip you with the exact same calibrated devices that typically retail for hundreds of dollars and are trusted by Fortune 500 companies and certified healthy buildings. This ensures every data point you contribute is actionable.
Measure PM2.5, PM10, CO2, TVOC, Temp & RH
Provide comprehensive parameters to understand the indoor environment
Wi-Fi & Ethernet Supported
Use Wi-Fi or Ethernet to upload the data for your viewing and contribute directly to the Global IAQ Observatory database
Continuous Data Analytics and Insights
View the data on our Data Platform to know the air quality you are breathing and gain actionable insights to improve your indoor environment
Building the World's Open Source Database
By simply plugging in a monitor, you contribute to a massive open-source resource used freely by scholars and policymakers globally.
Shaping Public Policy
Data from this network provides the hard evidence needed for legislators to pass laws protecting indoor air quality standards in public spaces, schools, and workplaces.
Fueling Academic Research
Scholars use this open dataset to study epidemiology and environmental health, leading to breakthroughs in understanding how air affects our bodies.
Standardizing Health
Helping international bodies establish global benchmarks for what constitutes a "healthy building," driving construction standards worldwide.
Your Privacy is Protected
We map pollution, not people. The goal is to understand environmental trends, not individual habits.
