Concerns over air quality have increased the market for products like the Plume Labs 'Flow,' which is a personal air quality tracker that can be used inside the home or out in the world.
The Plume Labs 'Flow' works by constantly tracking for things like particle matter, dust, NOx (exhaust fumes), ozone, VOCs and more. The device will then send you regular measurements and analyses through the accompanying smartphone app regarding air quality. From here, the device can provide tips on what you can do and where you can go when air quality levels are poor.
As worldwide levels of pollution in urban locations continue to increase, products like the Plume Labs 'Flow' will likely continue to be developed to satisfy a consumer preference for personal health management.
