Now this is just my personal opinion so please no lawsuits from the Hydroxyl crowd.
It's pure bullshit to me! A lot of pseudo science played on a bunch of restorers.
Operating the unit while people are occupying the area sounds extremely risky. To me I still smell a low level of Ozone

.
Who is responsible if and when someone screams they are feeling sick from your machine.
My experience has been it's slow to ineffective. It takes longer than Ozone to do it's job and is more expensive to operate. Who wins on this? Not the homeowner, not the insurance company....you and the Hydroxyl salesman.
Ozone is
not safe to use when occupied but works faster and works well. Just air the space out before it's reoccupied.
RW ozone should be fine to use in small doses. Run it a few hours and smell the clothes, if they still have an odor run it longer. The concern is elastic and natural rubber in wrist and waist bands they can take a small amount of expose but too much will degrade the rubber and damage the clothing. Ozone also does not penetrate
well so don't pack the too close together, use a small fan to help distribute the gas.
