Small Size Ozone Generator, Dailyart Portable USB Rechargeable Ozonator for Cars Refrigerator - Odor Removal Machine Review

Doesn't say but it's for the bag they ship and nothing else, died after a month, crappy innards, wrapped in expensive looking aluminum

It was the devas who taught. However, it does a great job. Says recommended for car or fridge. I used it successfully in Myers' 1 bedroom apartment. Ice is very dangerous to breathe when not in use

I like that it's really good at removing the smoke smell from my new car. I wish the cycle had lasted longer. You need to long press the button to get the best cleaning. I can run it 4 times before it needs charging. This is a good little air purifier and works great despite being small.

This is a low power ozone generator for small spaces like a refrigerator or car. I've only used it in the fridge so far and it seems to extend the shelf life of food. Although I haven't done a formal test, I see that in the few weeks I've been using it, fruits and veggies that tend to go bad if you don't use them quickly seem to last longer. It's good. The only thing is that the number of options for use and installation is limited. Otherwise, it's a reasonable price, so I'd recommend it.
