Mini Ozone Generator Deodorizer Air Purifier, USB Rechargeable Refrigerator Purifier Portable air Deodorizer for Small Space Home Car Shoes Closet Hunting Bag Clear Odor （Black）

This device is available from several suppliers. I am on my third (device and supplier). The first worked well but lasted only about a year. The second did not work from the start and would not take a charge. The third is still working after a week. Long may it continue to do so; it does good work in the fridge. Must try it in the car.

An interesting little device, I keep mine in the veg/salad draw of the fridge and I think it does help stuff stay fresh: I notice that mushrooms do not deteriorate as quick, and cut veg like peppers doesn't go bad as fast. The fridge smells better, or rather doesn't smell, which is good.The down side is that, being small, the battery is also small and requires recharging every three days or so (it's easy to tell as the bright blue light stops working.)I'd like it to be a bit bigger and to run for longer, say a week to a charge, but overall I'm pleased with it and would buy one again.
