you could just buy a ozone generator and have it on a timer for 15 mins every hour. u.v bulbs producing unstable o3 molecules that "bump" into complex odor molecules reducing them to co2 and water. There are dangerous aspects to ozone, prolonged exposure to high levels of o3 will steal o2 from your blood the same way carbon monoxide does, and slowly axphixiate you.
IF you chill near your plants then buy one rated for the size of your growroom, if you dont chill near your plants then you can buy one whatever size you want! because the only effects it will have on your plants is they will be pest free, as ozone fucks with little critters in a big way, even bacteria.
i didnt want to dum down the possible danger but they really are not very dangerous, if you have common sense and know that standing there breathing in the exhaust fan will eventually make you feel dizzy.as i said if you buy rated for the size of box you have there wont be much excess to breath. im fine and i have a big one. a company called uvonair make these. they are as effective as you could ever want and put carbon filters to shame and in the end are significantly cheaper and cosistently more effective. my honest experience
