It is an ionizer, not an ozone generator.
Ozone attacks and destroys molecules with oxidation. This can shatter small chain aerosols and hydrocarbons, or beak them into shorter chains. This means the remaining molecules don’t come across as the “human” smell they were before because they are physically not the same anymore.
An ionizer negatively charges particles passing through it. Most airborne particles are positively charged, repelling each other... which keeps them aloft. Throw some negatively charged ones in the mix and they stick together and fall from suspension. They don’t disappear, and they aren’t destroyed... they just fall down and settle. As they fall to (or pool up at) the bottom of the tree, they still smell like human.... the molecules aren’t altered in any meaningful way, simply stuck together.
It could be effective, I guess, in reducing how much of your scent makes it’s way downwind. However, at bow ranges, I would think that it would result in an abnormally high concentration of your scent accumulating at the base of your tree.
They are absolutely NOT equally effective. The ozone, though corrosive, is immensely more effective.
