Review on 🌬️ 6-in-1 Indoor Air Quality Monitor: CO2 Detector, PM2.5 Pollution Sensor, Temperature & Humidity Reader - Real Time Monitoring and Alarm by John Brouillard

Overall this is a nice little air quality meter to leave at home or take with you. Pros: - Ease of use. You can leave it on after charging or leave it alone. It turns on and off with the push of a button - Displays CO2, PMI 1, PMI 2.5, PMI 10, as well as temperature and humidity - The writing is clear and CO2 and PMI readings are easy to see even from a long distance - Compact and Lightweight: It's not big at all and should be very easy to carry in your backpack for any day trip or even longer vacation. Accuracy: Seems accurate compared to Purpleair's PMI readings so far. Cons: - Too easy. PMI readings alternate between 1, 2.5, and 10 every few seconds. It's not possible to simply configure it to display a specific PMI value. That's the main reason why I can't give 5 stars here. If I want to know the value of PMI 2.5 and its current PMI 10 mapping, I have to wait for it to go through PMI 10, then to PMI 1 and finally to PMI 2.5. It would be nice if I could just glance at the monitor and immediately get the information I need.
