If you care about your overall health, you want to know the quality of the air you breathe. When you use the Flow 2 by Plume Labs Portable Air Pollution Sensor, you’ll get that information. This little gadget straps onto just about anything and tells you the quality of the air around you. In fact, this air quality monitor measures the particulate matter of PM1, PM2.5, and PM10. Additionally, it’ll tell you how much nitrous oxide—or NO2—and volatile organic compounds (VOCs) are in the air. So you’ll know if there’s any of that nasty stuff spewing from vehicles or buildings and contaminating the air you’re breathing around you. Especially important for vulnerable populations, good air quality is a necessity for everyone.
