Should you buy an air purifier or air quality monitor first? This guide compares immediate relief against diagnostic insight to help you decide.
Acenew Smart Air Quality Monitor with CO2, WiFi, Temperature & Humidity Sensors
This smart air quality monitor is perfect for keeping an eye on your bedroom's air while you sleep. I use mine to make sure CO2 levels stay low and the room stays comfortable overnight. The NDIR CO2 sensor updates readings every 3 seconds, so you always know the air quality in real time. If the CO2 gets too high, you can set the screen to auto-off and silent monitoring—no buzzing alarms to wake you up. Just raise your hand to check readings, and the backlight turns on. The Tuya Smart app gives you all the data, plus CO2 alarm history and adjust alert thresholds. You can also see temperature and humidity at a glance. Keep it plugged in for continuous use; the battery lasts about 3 hours if needed. Note: It doesn't measure PM2.5 or formaldehyde.
