This well-designed and minimal air quality monitor tests for VOCs, PM2.5, humidity, temperature, and CO2. VOCs are chemicals that turn to vapor or gas easily. For example, formaldehyde in paints and varnishes can turn to vapor at a certain temperature, and breathing formaldehyde is harmful to humans. PM2.5 is extremely fine dust, which can also have adverse effects on human health. The Awair monitor connects to the Awair app, which gives detailed info on the contents of your air as well as tips to improve your air quality. It works with Alexa and Google Home. The HI-150 is compact enough to fit in your pocket and thus extremely portable. It measures VOCs, humidity, temperature, and PM2.5 and PM10 particulates. PM10 is dust that is slightly larger than PM2.5, as the numbers refer to micrometer measurements. The LED display is easy to navigate with one button to switch between screens, either giving you a general air quality rating or a more detailed rundown. Using a laser particle sensor and an electrochemical sensor combined, this professional air quality monitor measures VOCs, HCHO (formaldehyde), PM2.5, and PM10 while also giving a general air quality index reading. An AQI reading of below 100 is considered safe, while anything greater than 100 is considered unhealthy. The Temtop runs on a 6-hour rechargeable battery and can be charged via USB.
