• Real-Time Air Quality Monitor: An onboard sensor with a color indicator keeps you informed of changing particulate levels and automatically adjusts the fan speed when Auto Mode is active.
• Long Filter Life: Replace the Green True HEPA and carbon filter only once a year under normal use, lowering ongoing maintenance and keeping ownership simple.
