Review on 🧺 Lucalda Portable Ozone Generator: USB Rechargeable Odor Removal Machine for Fresher Fridge Food & Extended Shelf Life by Doreen Johnson

These ozone generators really do work as advertised and are great value. However, the internal battery (type 18650) does not provide the promised 5 days of operation when set to 1 minute ozone every 3 hours. The 2 samples I got run a maximum of 2-1/2 to 3 days and only 24 hours when used in the fridge. does not work in 1 minute mode when charging every 3 hours. They also work on charging if you set the ozone production mode for 1 hour and turn off the mode. Update: 1st Sep 21 1 minute of ozone every 3 hours is just the right amount for us to not smell ozone or other musty smells. So we ordered a few more, 1 for another room in the house and a few as gifts for orphanages! They did a great job in our basement/storage area getting rid of the 'musty smell'.
