Review on 🌡️ Real-Time Temperature Monitoring for Formaldehyde Pollution by Chris Horton

It shows differences in HCHO and TVOC readings which I would like to know. However, particulate matter (PM) values are completely useless as they range from 1 to 5. In contrast, the Dylos Pro air quality monitor, which I've used for many years, is far more sensitive to particulate matter levels. It also lacks CO2 and O3 sensors, which are also important to monitor. It has very bright light from two sides, making it unsuitable for bedroom use at night.
