Barely used (+ new original box) portable air quality monitor Atmotube Pro + phone app

Barely used. As new. With original box. Kept plugged in indoors. Selling as my new place can't facilitate 2 monitors. Among world's best air quality monitors. Lab level sensors. Award winning. Tried other expensive and cheap air quality monitors before. Others were inaccurate or loud or not versatile enough for real life practicality. Great tool for improving air quality during sleep which is underestimated and solves many health issues. Also great for health and safety of babies and children and elderly. Also great for industry. Press button for quick quality check. Details via phone app Bluetooth. Custom alert triggers USB C charging/power. Battery lasts over a week depending on use settings. Can set it to realtime full throttle performance whenever plugged in which is so handy (think power banks or even powering from your own phone!)
