i don't know anything about that one but since i don't see a bulb i'm guessing it is CD type. NGT (nongreenthumb) i believe uses one of these (and loves it):
IONIC BALL AIR PURIFIER IONIZER CLEANER W BREEZER OZONE on eBay, also Other Methods, Air Purifiers, Gadgets Other Electronics, Consumer Electronics (end time 27-Nov-07 22:15:00 GMT)

be sure whatever ozone generator you use, get the test strips and set it up right. if anyone starts complaining about sore throats - be aware it could be the ozone (or they might be coming down with something).
