OzoneGuard™
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.
Please read this product instruction manual for impor-
tant safety information and operating instructions.
