I have been using this method with a nebulizer for years. I inhale several times, 2-3 times per day. I used to get the flu twice a year, every year. Since I started H2O2 therapy I have not had even a cold or sniffle in the last 10 years! Could not worry less about Covid.
I have also used it more intensively to help with detoxing (longer sessions 4 times a day), and on the 2nd or 3rd day experienced an intense Herxheimer reaction immediately after, which proved beyond a doubt the effectiveness of this therapy.
