For this task I absolutely love my Xiaomi Mijia indoor air quality sensor[1].
Under $50, nice touch screen, WiFi, TVOC, PM2.5, CO2, temp, humidity. Have one by a laser cutter (particulate), one in a paint booth(TVOC), and one in the office conference room (when the CO2 is higher than 1200 its time for a fresh air). A+ product and so much better than what I could build myself at that price point. If you find yourself in mainland China do yourself a favor and drop into a Xiaomi store.
