Review on 🌬️ Refrigerator Deodorizer: Compact Ozone Generator Air Purifier for Small Spaces – Rechargeable & Efficient Sterilizer for Refrigerators or Cars by Adam Radford

It works really well, I set 40 minutes to sterilize and deodorize my face mask. Works 40 minutes and turns off. I haven't tried other settings yet. My face mask smells of ozone if I take it out of the case too soon. I use a 1.5 gallon plastic case with a lid. You must wait an hour before taking out the face mask. Ozone damages your lungs if you smell it strongly.
