ok guys you can make a homemade ozone generator for about $30.
buy ANY florescent fixture with a cord already attached.
then just by a uv bulb of the same rating. i use a$22, 12" T5 under cabinet florescent fixture, with a 9 dollar uv bulb, and it will kill every trace of odor in my attic.
the secret i found is to mount the bulb vertically in a large tupperware container with layers of cardboard spaced about an inch apart, (like a series of baffles) hot vent air comes in the bottom, and goes back and forth across the layers till it exits holes at the top. high volume low speed air is the best. also.
DONT GO INTO THE LIGHT.
seriously if you can see the light, your getting cataracts.
