Sharper Image SI867 用户手册

The Sharper Image Quadra was packed with an OzoneGuard 

front grill preinstalled. To clean the OzoneGuard and the front 

grill, follow the directions for Thorough Cleaning of the front grill.
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 air purifier 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 air purifier. 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.
