A portable air quality tracker called Atmotube is currently being manufactured for consumers. It will fit in your pocket or on a key chain, according to TechCrunch. The device connects to a smartphone app that can tell you if the air you're breathing is toxic by measuring the levels of carbon monoxide, volatile organic compounds (VOCs) and allergens.

"Every day, we unconsciously take more than 20,000 thousand breaths and don't even think about most of them," said co-founder Vera Kozyr. "Over time, exposure to carbon monoxide and volatile organic compounds has been linked to an increased risk of heart disease, stroke, liver and brain damage, and even cancer."

Atmotube displays the concentration of particles per million of each volatile organic compound in the air that you're breathing, and also features a color-changing LED that is blue when air quality is good and red when it is bad, according to VentureBeat.

Air quality trackers have been on the rise in the past year, although until now these sensor-packed devices were only designed for use in homes, according to Gizmag.

"We decided to create a beautiful and functional object that can seamlessly become part of your life, alerting you to potential danger in the air," said Kozyr.

Atmotube is currently for sale on Indiegogo for $79.
