What does OzoneGuard™ do?
With the OzoneGuard in place, a significant portion of ground-

level ozone inside the air purifier — including any trace levels of 

ozone by-product — is converted into oxygen before the cleaned 

air circulates back into the room.
Why is the OzoneGuard™ smaller than the grill itself?
The majority of the air output is directed toward the center of the 

grill and therefore a larger OzoneGuard isn’t necessary.
Does the Ionic Breeze still have the Negative-Ion Feature™ option?
Yes it does. The new OzoneGuard front grill does not affect the 

popular Negative-Ion Feature of the Professional Series™ Ionic 

Breeze

®

 air purifiers. An emitter at the bottom of the new grill has 

replaced the ionizing wires inside the original grill. The feature 

itself works the same way as before.
