About every 6 months you should check your lter to see if it 
needs to be replaced. Heavy build-up on the lter can cause the 
energized eld on the lter to not operate properly.
1.  Turn the air sanitizer off and unplug it from the wall outlet.
Warning: Wait 10 seconds before opening the panel.
2.  Push down on the  Hunter logo to release the door. Figure 6.
3.  Gently pull the door away from the unit and lift away. Figure 
7.
4.  Remove the HEPA Filter from the unit.
5.  Clean the outside of the unit and the door with a soft, damp 
cloth. 
NOTE: Ensure the door is completely dry before reinstalling it 
on the unit. Failure to do so could cause damage to the lters 
or motor.
6.  Check the lter for particle build-up.
7.  If the lter needs to be replaced, remove the new lter from 
it’s packaging and insert it into the unit. Place the lter back 
in the unit so “This side faces you” is visible. Ensure the lter 
is seated fully into the unit.
NOTE:  If  the  lter  is  not  fully  engaged  in  the  unit,  the  air 
sanitizer will not run.
8.  Set the tabs on the bottom of the door into the notches in the 
base of the unit and rock the door up until the top of the door 
makes contact with the magnet. Figure 8.
9.  Push the Hunter logo in until the door “clicks” into place.
10. Plug the air sanitizer back into the wall outlet and resume 
use.
11.  Touch the sensor pad for 3 seconds to reset the lter counter.
Note: If the lter is not seated properly inside the unit, the air 
sanitizer will not operate.
