For the past two years, Plume Labs has had one mission: helping you stay ahead of air pollution to improve your environmental health.

Today we are incredibly proud to unveil the design of Flow by Plume Labs, the first smart, mobile air quality tracker.

Flow is your environmental companion that helps you understand, monitor and lower your exposure to air pollution – indoors, outdoors and on the go.

A tall, sleek and elegant body, a versatile leather strap, and a matching dock and cable make it easy to charge at home and carry on the go.

Flow is built to last yet distinctive, discreet yet beautiful – a helpful companion you can be proud to have at your side to find fresh air every day.


  • Track the full range of indoor and outdoor pollutants, including particulate matter and dust in the air, NOx from car exhaust, VOCs from household products, and irritating ground-level ozone. Also track temperature and humidity for your environmental comfort.
  • Monitor your exposure with tailored air quality alerts on Flow’s companion mobile app. Discover easy ways to escape pollution, and find the ideal moment for an outdoor activity.
  • Improve what you breathe by building healthier routines, and help map your city to find clean air hotspots. Join a global movement of citizen monitors helping make the air we breathe more transparent.

We’re unveiling Flow for the very first time this week and are proud to be highlighted as a CES 2017 Innovation Awards Honoree in the ‘Tech for a Better World’ category.

With our beta test starting soon in London, we’re months away from opening pre-orders this fall – sign up here to be the first to know!

Fighting air pollution is a long journey, and we’re just getting started. Thanks to each and every one of you for being along for the ride.

Clean air, onwards!
