## Abstract

A device and method is provided for converting oxygen within air into ozone. The device has a portable housing with an air inlet and an enhanced ozone air outlet. A lamp housing is positioned within the portable housing and has a plurality of UV lamps for emitting UV radiation, the plurality of UV lamps extending from one end of the lamp housing to the other in a generally parallel configuration. The device also has a blower positioned within the portable housing for moving the air into contact with UV radiation from the plurality of UV lamps. The device further includes a plurality of baffles positioned within the lamp housing for dispersing the air as the air moves through the lamp housing. The device can be used to eliminate odors and contaminants found in the air, as well as to eliminate oils and contaminants found in water and to kill insects.
