BPSHINE Portable Ozone Generator Mini air Deodorizer USB Rechargeable Air Purifier Sterilization Ozonator for Car, Rooms, Pet, Office (Black)

Produces a good amount of ozone for its size; great for eliminating smells. Perfect for small areas, closets, fridges, backpacks etc.You need to leave the room when this thing is running !

The instructions are very poor English. For example, the pushbutton labeled 'power' does not turn the device on, rather it temporarily lights up the LED battery indicators to let you know the charge state.However, the actual device seems to be reasonably good quality and works well. I used it to deodorize a vehicle that had been smoked in, I have run it for 30 minutes 3 times and the result has been great.What needs noting is that in order for ozone to be effective, the source of the odor needs to be cleared/cleaned first. Ozone then does a great job of destroying traces of the odor left behind. (This is true for ALL ozone machines, not just this one).I love how this method actually gets rid of the smell, without any sort of lingering masking agent.
