I am suffering the same burns and my research says a minimum 4 hours of "airing-out" after sanitizing will allow the ozone residue to dissipate. My face is a mess and the rim of my nostrils a crusty sore
I have had the exact same issue of what appears to be ozone chemical burns around my nostrils and strap contact points. Seems, we are supposed to remove the headgear and let it air out for at least 4 hours to allow ozone dissipation. As I write, my face is a mess from the ozone burns
