I built an Ozone Closet two years ago. I think it works. I believe it reduces ordors from my clothes. I have a timer on mine (25 mins - boots too). When it is on, You definitely don’t want to breath in that stuff. There are a lot of people who do wierd stuff to eliminate oders (or replace them). I chose to do it electronically. Only an idiot goes into the woods with smelly clothes. And only an idiot doesn’t consider wind when hunting. I hunt off the ground to help control my odor - if people don’t do that, more power to them. Don’t hate me cause I use science.
