when you say "molecule", by definition that would be a non-living particle. Your statement about taking away oxygen in the air so they can't breathe applies to the living bacterial cells that live and grow on our sweaty places and stay in our clothing. They produce the molecules that we associate with bad smells.
Atmospheric oxygen that we breathe is O2That's 2 oxygen atoms sharing electrons, kind of like holding hands or close dancing. Ozone is O3 ... That would be 3 oxygen atoms sharing electrons.
What people don't realize (we take it for granted that oxygen is good for us and therefore harmless) is that a single oxygen atom is HIGHLY reactive. That's why things oxidize, or rust (for iron). Ever leaned up against an aluminum sided house and gotten covered with white dust? That's aluminum oxide, or Al2O3. My point being that Oxygen atoms sort of attack and force other atoms to give up electrons so they can be stable. The oxygen we breathe has already gotten to be very stable by sharing electrons with 1 other O atom. When they form that ozone situation, they are much less stable. Therefore, when ozone comes into contact with other molecules, it will split apart and attack the individual atoms of the other molecules causing them to break apart.
Smell is caused by the specific shapes that molecules have. There are actually tiny little receptors in noses that accept molecules and send a message to the brain about what that molecule smells like (kind of like a lock and key situation, different molecules/keys trigger different signals/open different locks) When ozone molecules come into contact with these "scent molecules", they basically cause them to degrade into smaller, simpler molecules that do not trigger the same scent signals. Kind of lock grinding your key into a different shape. It might open a lock somewhere, but not the one it was designed to open.
You're pretty much right on about why too much ozone kills you. Too much ozone means not enough of the atmospheric O2 that we require to breathe... you basically suffocate

As far as I can tell, the carbon traps the scent molecules so that they can't get out. One of the coolest things about Carbon atoms is that they have the ability to form long chains. They have 4 electrons to make bonds with. Our organic molecules (carbohydrates, proteins, lipids, and nucleic acids) are basically long chains of carbon atoms attached to each other with other stuff hanging off the side.... think long trot line with droppers every foot or so... the main line is a chain of C atoms, and the droppers are hydrogens/nitrtogens/oxygen and other atoms in various configurations.
Carbon can even be manipulated into what are basically tubes and spheres... Google Image search for Buckminsterfullerene or bucky balls. I'm guessing the "activated carbon" is some form of these things that have the ability to act like cages for the scent molecules.
If the ozone could penetrate the carbon traps and interact with the scent molecules, it would probably work. If the scent molecules become bound tightly to the carbon molecules in such a way as to prevent the ozone from interacting with the scent molecules, not so much.
I'm also guessing that even if the scent molecules are broken down, the resulting smaller molecules would be just as likely to be absorbed and held by the carbon layer. The problem is that the carbon basically absorbs the other molecules and becomes saturated... just like a sponge can hold only so much water. You need to get the carbon to release the molecules. According to the experts it's the high temperatures that get the carbon to do that.
Now that I've written this and seen it down on paper (or screen, as it were)... I'd have to guess you'd have little luck reactivating carbon with ozone at low temps. But as any good scientist would tell you, you'll never know unless you test it out. Just how you would test whether or not your Scent-Lok is working basically means you need to be in a tree hunting.... sounds like a great excuse to take those extra few weekends off and hit the woods this year!
