setting of zero (0) indicates that the unit is off. One (1) is low speed. Two (2) is

FilterChange Calendar: The filter counter is designed to optimize the 
performance of the air purifer by reminding you when to change the HEPAtech 
Filter and pre-lter.
HEPAtechFilterCalendar:  The HEPAtech Filter 
indicator is located at the top of the calendar ring.  To 
set the HEPAtech Filter counter, rotate the calendar 
ring to align the month that you installed the lter with 
the top indicator.  Since the lter is designed for 6 
months use, the two indicators will serve as reminders 
to change the lter every 6 months.
Pre-lter Calendar:   The  inner  knob  of  the  lter 
counter  is  the  pre-lter  counter.   To  use,  align  the 
knob with the month that you installed the pre-lter.  
The replace symbol on the inner knob points to the 
month in which you should install a new pre-lter.  The pre-lter is designed for 
three months of usage.
