THE AIR AROUND YOU
Why should you care
about air quality?
Particulates
Dust. Pollen. Wildfire smoke. Pollution. A lot can be in the air you can’t see. Get a more personal view of particulate levels, wherever your day takes you.

On monitoring indoor CO₂ levels
I have a CO2 monitor on my desk. It beeps whenever ppm>1000. Air quality has a much bigger effect on health than people realize.
— Elon Musk

GOOD QUESTIONS
Let’s clear
the air.
How does this differ from AQI in my weather app?
The AQI in your weather app comes from a measuring station that may be many miles or kilometres away. Halo Air is on your phone because air quality is hyperlocal: to the room you’re in, the street you’re on, and the places you go.
What do I do with the information?
See how your surroundings respond to everyday changes, such as opening a window or choosing a route away from a construction site. Track patterns, set your own alert thresholds, and get to know the air around you.
How does Halo Air attach to my phone?
Halo Air is designed to attach magnetically. The original design uses MagSafe on compatible iPhones and a magnetic ring for Android phones. Visit the campaign for the latest compatibility and development details.
Where can I find project updates?
Visit the Halo Air Kickstarter campaign for development updates and the latest project information.
