Your cart is empty.
A palm-sized sensor that shows what you and your family are actually breathing, wherever you go — so you can make simple, everyday choices.
The one or two streets you walk every day can be far more polluted than the blocks around them, and more than the nearest fixed station will ever show. Your own monitor tells you which route is cleaner, so you can pick the right path for you.
Your street can read higher than the nearest official monitor.
Clip it on, drop it in a bag, or leave it running at home.
From box to monitoring in under 2 minutes
Keep it with you, updates every second
Leave it at home or outdoors, updates every minute
