I'm no expert on this, but I don't see how the unvented hood could have
any effect on moisture. It might I suppose (conjecturing out of my league
here) have an indirect effect as the air cools while travelling through
the hood, causing moisture to condensate out of the air. But the
resulting water would have to end up somewhere.<br><br>

nothing in using that vent for moisture dissipation? I do think the vent
is trapping moisture as the windows aren’t fogging up when I use it but
did before when I did not. If it’s just for grease and odors, I’ll
stop wasting the power in using it.<br>

They're just a second-best solution to dealing with grease and odors when
exterior venting is not possible. I've often had to resort to them in
apartment renovations. They're moderately effective at best.<br><br>
I doubt they'd have any effectiveness on gasses such as CO since they
aren't readily filterable. Nor on heat dissipation.<br><br>
