We take thousands of breaths every day. Yet we give little thought to exactly what we're breathing in. The Atmotube Air Pollution Monitor is a highly portable tool that aims to keep you informed of the quality of the air around you. It constantly checks for levels of volatile organic compounds and harmful gases like carbon monoxide, and pairs with a companion app to let you check the current air quality or track it throughout the day. And with a cylindrical titanium body, it's one gadget you won't mind carrying around.
