Fresh air is just around the corner

WHY FLOW

  • «Technology can make the quality of our air much more transparent, and if we can empower people to take action to improve their own health, then together we can act to bring an end to air pollution.»

    Romain Lacombe, CEO, Plume Labs, at TED 2018

  • «It is possible to identify and avoid localised risk spots. Having a device like this, turns out, can make a difference.»

    Leslie Hook, Financial Times
WHAT IS FLOW FOR?

  • Make commuting a breeze

    We are keenly aware of which transportation options emit more CO2 but it’s harder to know which one is best for your lungs. Car, bus, train, subway, hyperloop or rocketship: Flow helps you compare the data between your commutes and pick what’s safest.

  • Take it for a spin

    Flow is a cyclist’s best friend. It will help you choose the smartest itinerary to drastically reduce your exposure to pollution. Pedaling in the smog is a thing of the past, you shouldn’t have to fear peak hour!

  • Give your lungs a chance

    Flow will also be a valuable partner for the sensitive urbanite. While it won’t replace your asthma or allergy treatment, by warning you of pollution peaks and giving you timely guidance it will help lift a weight off your shoulders.

HOW FLOW WORKS

  • Technology that breathes

    An exclusive 360° air intake design paired with the world’s smallest mechanical fan makes sure the outside air flows perfectly through the device. Reliable measurements start with thoughtful design!

  • Live feedback

    We wanted to keep things simple. A single press on the device’s button gives an immediate reading of what you’re breathing and a glance at the app will show you everything else. Hassle-free operation to make daily activities that much more enjoyable!

  • Hand-held brainiac

    Flow’s next-gen Neural Engine uses advanced algorithms to refine its measurements. With version 2, the on-board sensors have been optimised to detect down to nano-scale particulate matter and improve accuracy for gaseous pollutants.

  • Heavyweight tech, featherweight package

    70 grams of science: A custom 30x30 mm detection chamber houses a powerful laser detecting Particulate Matter through light scattering, while gasses (NO2 and VOCs) are measured with metal-oxide reactions using a tiny membrane heated up to 250°C.


FLOW APP

  • Clearer than ever

    The Flow companion app reveals what’s in the air around you. At home, at work, at school, in your favorite café or when you’re out for a run… You’ll always have the data at the tip of your fingers.

  • The big picture on a small screen

    The Flow app’s brand new dashboard gives you the bird’s eye view of what you’ve been breathing. Want to dig deeper? Your full history and the comparison of your exposure between different times and places are just a click away.

  • Enlightening and inspiring

    The Flow app is the perfect place to start your air quality journey. An interactive user guide, the latest tips and science to best protect yourself and tutorials to quench your learning thirst. All in the same place!

  • Safe travels
