for those that use ozone machines...do you turn them on and leave the boat for a few hours or can you stay on board?
In twenty years of living aboard and my wife having life threatening allergies to just about everything, out boat had to be kept immaculate. Every bilge compartment was painted high gloss white, washed regularly and bleached at the smallest hint of mildew, odor, fungus or bacterial growth. We ran two Heaven Fresh 300C air cleaners 24/7. This unit has HEPA filter, UV filter, charcoal filter, ion generation and ozone generation. The ozone generator has a separate switch as it should not be running when you are onboard. Ozone kills bacteria ..... even the good bacteria that we need in out bodies. Ozone will corrode some metals in heavy concentrations but remember there is ozone in the air anyway and all metals corrode with or without generating additional ozone. We ran the ozone once a week or so, when we were leaving the boat for an afternoon or a day. We never had an odor of any kind on the boat, our synthetic rubber did not disintegrate, our metals did not corrode and our children have ten toes and ten fingers.
