Review on 📊 Formaldehyde Temperature Humidity Portable Chemical Pollution Tracker by Robert Dabney

I plan to use it to have peace of mind when traveling, especially when renting from Airbnb and sometimes hotels. Temperature readings are useful, but humidity and HCHO readings are critical. Obviously VOCs are bad for your health, but viruses prefer low humidity. I compared the temperature and humidity readings to my thermostat above and the humidity was identical. The temperature deviation is <1°, which is absolutely acceptable. I couldn't compare the formaldehyde values, but I assume they are just as accurate. This isn't meant to be left on over the weekend, but to occasionally check air quality, which is perfect for my needs.
