How do I use the Auto-Off Timer?
Tap the Timer button until the desired pre-set run time (2, 4, or 8 hours) is illuminated on the display. To exit Timer mode, tap the button again until the Timer button light shuts off. Do not use this option if you want the air purifier to run continuously. (Page 7)
